Customer Testimonials
Edwin & Harold were professional & very congenial. My problem was addressed the same day as my scheduled appointment.
Knowledgeable, good service , great customer service from booking with Amanda all the way to having the technicians in my home
Excellent customer service! Took the care and time to patiently explain everything and listen to my needs and concerns and offered multiple options to consider at my own pace.
Edwin and Harold did a great job and explained everything that they needed to fix. Peace of mind is so important with electrical work.
Prompt service, no B.S. Honest people doing honest work, and always very polite and personable. Completely satisfied with their service.
Had Erwin and Harold out for a second time to do more work in our home we are renovating. I have no complaints about this company, they are honest and give plenty of options to work with your budget. Respectful, understanding and very thorough explanation of their work. Highly recommend you get a quote from them before paying double to the larger companies!
Edwin was very informative and respectful. Quick and effective work. Very thorough and good at his job. He discovered that every outlet that was worked on previously by a unlicensed handyman were done incorrectly. My home could have burned down, thankfully i caled a professional. I would recommend him everytime
Erwin did a great job on the lights in are den he was here when he said he would and gave a far price for what he did.
Erwin did an awesome job! Super professional, on time, and really knows what he’s doing. Everything came out great, and he made sure it was done right. On top of that, he’s just a really nice, friendly guy—easy to talk to and made the whole process stress-free. Definitely someone you feel comfortable having in your home. I’d 100% recommend him to anyone looking for a reliable electrician!
Erwin and Harold were absolutely fantastic. Courteous and clean service. Very professional. Advised me on what was needed to bring my kitchen oven up to code and accomplished my installation quickly and same day. Estimate was equal to what I paid. Very honest workers and professional experience. 10/10! Will be calling them for everything in the future for electric. Amanda, the lady who I scheduled the appointment with was also friendly and professional and answered all my questions. Overall a fantastic company, I couldn't speak highly enough of them!
The team was wonderful. They went above and beyond to make sure that I was satisfied, even offering to help me with a few loose ends on other projects. Their reprices were fair and upfront with no hidden fees, and I never doubted the integrity of their work. I will be coming back to them for anything electrical in the future
Harold came in, was very proffesional. Fixed our outlet and panels in a timely manner and were very accomodating. Would reccomend.
The outlet wasn't working he came and fixed it quickly and was very respectful.
This is my first experience with Edinson Electrical Solutions. I was very pleased with their service and will use them for all my electrical needs in the future. They were very professional and respected my house. Thank you very much.
I have used Edwin a few times for my house and each time he is very customer oriented, shows up when he says, and does a fine meticulous job. I recommend him highly if you are looking for an electrician.,
Jr and Harold helped me with an electrical issue where I kept losing power in my bedroom and living room. They came out, diagnosed the problem quickly, and fixed it the right way. What really gave me peace of mind was their lifetime craftsmanship warranty. It’s great knowing the job was done properly and that they stand behind their work. Highly recommend them!
Erwin was amazing. We needed an entire new panel, it was waterlogged and he worked the same day doing everything over for us. He was so amazing that he even got us a pizza out of the kindness of his heart. I definitely want them any time I have any other issues. 10/10 would recommend.
Erwin is great at what he does he came through for me and my family during a snowstorm storm so if you have any electrical problems I recommend you give him a call
Great service. Quick efficient and very good customer service. Will definitely book with Edinson Electrical solutions again.
They truly came through for us. This wasn’t an easy project—our entire parking lot was without lighting—but their team handled it quickly, safely, and professionally. They diagnosed the issue, coordinated the work, and had everything fully operational in just two visits. We’re grateful for their efficiency and expertise.
The electricians(Erwin Harold and their crew) did a wonderful job. Erwin explained step by step in details on the things they were going to work on before they did the job. They accommodated everyone in the household especially our autistic son. With all the cosmetic work that had to be done, in the end,it looked like no damage to the house was even done. Thanks to them now we have permanent power instead of partial power. We will definitely recommend them to everyone.
Erwin and Harold from Edinson Electrical Solutions visited us to work on the dishwasher, the circuit breaker panel, outlets and possible installation of a new outlet box in the basement. Erwin was very thorough. He went through all the requirements of what needed to be done and provided options for us to pick. We wound up putting in a new outlet box for the dishwasher (which he diagnosed as needing replacement). He installed a new whole house surge protector at the circuit breaker panel. He fixed a few of the troublesome outlets. We decided not to install the outlet box in the basement at this time. What was impressive was the time he spent explaining the pros and cons of what needed to be done. I appreciated the explanations. They did an outstanding job for us and not was reasonable for the work that was performed.
Erwin and team were great! Provided multiple options for our project so we could decide what works best. It was a large project, upgrading 2 panels, removed 1 meter and went to 200 amps. Communication was great throughout and he made us a priority. We used Edinson for a previous project as well, we will continue to use them and would highly recommend them for a small or large project.
Harol y Jr. son electricistas increíblemente profesionales y amables. Se tomaron su tiempo para asegurarse de que todo estuviera bien y fueron honestos con nosotros sobre los precios. Nos ayudaron con todas nuestras dudas y nos brindaron un servicio excelente. Harol and Jr. are incredibly professional and friendly electricians. They took the time to make sure everything was okay and were honest with us about the prices. They helped us with all our questions and provided excellent service.
Erwin came out and was very professional. He explained everything and did not rush. I would absolutely recommend him to others.
Juan was excellent! He showed up on time, was very professional, and completed the job quickly and neatly. Great communication and reliable service. I’ll definitely call him again when I need electrical work done.
Erwin and Harold did an excellent job replacing many outlets and lights for our remodel. They also upgraded several switches for us. They were very respectful of our house, cleaning up after themselves as they worked. We will be calling them in the future for other work we will need to have done.
Erwin came during a same day emergency that required a readjustment and reinstallation of improperly connected wires connected from the ceiling to make sure the lights worked properly. He was professional and made sure everything stayed working properly. Totally would recommend! Five Stars!
Erwin came to fix an electrical issue I had with my lights not working in my bathroom. He was very flexible with when I was available and efficient in getting the issue resolved quickly and professionally. I would recommend this company 100%!
Erwin was amazing! We called when our circuits when being tripped and we didn't know why. He came and was professional and courteous. He explained everything he was doing and checked in multiple times so we knew what to expect. The job was bigger than he expected but he stayed calm and worked diligently until it was finished. He gave us multiple professional recommendations before he left for things we can improve our efficiency.
We were having some intermittent issues with power in our house. Erwin came out and checked everything out for us. He was great and answered all of our questions about the state of our wiring and helped us plan out future projects. The price was well worth an hour of his expertise, and they’ll be at the top of our list when we do start on renovations.
Amazing service! Erwin was extremely professional and resolved my issue quick! I would highly recommend.
they was fast and cleaned up. Showed and explained everything that happened. it was very pricey but they did a good job.
Erwin was great, I had a partial power in my room and my husband found him on Google he came right away to check and fix the problem.
Edinson Electrical was referred to us by our realtor, Rudy Amelio. They were available very quickly to do the work. Erwin checked the site; and Harold got started immediately. We had a long list of small projects which they completed rapidly a d skillfully. Harold was very respectful of our property. They found some additional items to repair and checked and double checked everything. They were both very polite, responsible, thorough, as well as informative. Erwin and Harold aee some of the nicest, most honest people I’ve had the pleasure of meeting and working with. Highly recommend!
I recently purchased a house, erwin and his crew, help us with a City requirements list, pull the permits i guide us on the entire process
I had problems after all the rain we had with my GFI outlets outside. Edwin came in a timely manner and completed it neatly and correctly. They are both working perfectly and safely now. I highly recommend this company!
I live in an apartment complex where several units lost power after a tree came down during a storm on Father’s Day. It was pouring, and honestly, we thought we’d be without power for a long time. But Edinson Electrical Solutions showed up quickly and got right to work. They were professional, focused, and clearly knew what they were doing. It was impressive to see how they handled such a big job under tough conditions. Power was restored to all the apartments faster than we expected. Truly grateful for their dedication and the quality of their work.
We had an emergency when a tree fell and knocked out our power even on Father’s Day and during heavy rain. Harold and his crew from Edinson Electrical Solutions showed up fast, handled everything safely and professionally, and got our power back on with excellent work. In a stressful moment, they brought peace of mind. We highly recommend Edinson Electrical Solutions for their quality, responsiveness, and dedication!
I contacted Erwin for help with 2 sub panel installations at my residence and from the moment I called him to the moment he walked off my property it was an example of customer-first professionalism. If you want to have a quality job done, with a friendly, safe and professional electrical contractor, look no further. He handles everything from A to Z and does not consider the job done until the customer is satisfied. I cannot say enough positive things about my experience with him and his team. Outstanding service. If you choose this company, you won’t have any problems
I had a great experience with Edinson Electrical Solutions. They helped make my house much safer by upgrading all the smoke alarms, fixing some wiring issues with my baseboard heaters, and installing a electronic surge protector. Their work was very thorough and professional from start to finish. I’m extremely satisfied with the job they did and would definitely recommend them to anyone looking for honest, high quality electrical work.
Juan and his crew were very professional, clean and respectful of our home. They fixed a ceiling fan and installed all new smoke alarm / carbon monoxide detectors, efficiently throughout the house.
We recently purchased our forever home and spent hours searching for a highly reputable electrician to help us with a large project. Erwin is the epitome of professional; he came for the estimate and talked us through every viable option to make major upgrades to our VERY outdated knob and tube electrical system. He was very receptive to our input and made us feel like we put a plan together as a team. His dedication to his clients is very apparent as he followed through with all the work he said he would do within the timeframe he provided; not only that, but he went above and beyond to ensure that we were left feeling safe and secure before he wrapped things up. He completely alleviated all our initial concerns by the time the project was done and has remained in contact to make sure everything has continued running smoothly. It’s rare to find someone that genuinely cares about others in the capacity that he does with the skills to boot. Don’t just take my word for it; give him a call and I guarantee that you will have him on standby for all your current and/or future needs. Keep up the great work!!!
Honest, reliable and quick to respond. It doesn’t get better than Edison Electrical Solutions.

I’m very impressed with Edinson Co, specifically having worked with Erwin to estimate and assess an older century house’s electrical system. The process was smooth, thorough and actually enjoyable. Erwin is a down to earth guy and will have no problem keeping you aware of what needs to be done work wise, albeit very kind, funny and friendly to talk with. Never once did I feel pressured or unsure about any of his work. The process was simple enough to any homeowner; going off a general inspection and digging even deeper into whatever pops up on the report is exactly what Erwin did. His report was thoroughly informative after taking time checking for GFI circuitry and for k&t. If you have an older house and are interested in finding out what kind of projects you might encounter, Erwin definitely will shed some light on the situation. I am so grateful Erwin was referred to me, being that finding an honest and dedicated electrician is golden nowadays. Thank you so much Erwin!
Erwin arrived on time. The problem was fixed. Very professional. I would call them again

Air Conditioning Wiring Service
Air conditioning systems pull significant electrical loads, often between 15 and 60 amps depending on tonnage and efficiency rating. A dedicated circuit is required for nearly every central AC condenser, and skipping this step causes nuisance tripping, overheated wires, and equipment damage. Edinson Electric calculates the exact circuit size based on the manufacturer’s minimum circuit ampacity, also known as MCA. We then select the correct wire gauge, breaker amperage, and disconnect rating for that specific unit. Copper conductors are used in most residential applications, sized at 10 AWG, 8 AWG, or larger when the load demands it. Every run is secured properly inside walls, attics, or conduit, with strain relief at each penetration. Our electricians also verify that your existing electrical panel has enough available capacity before adding a new AC circuit. Load calculations follow Article 220 of the NEC, which prevents overloading the main service. When panel space is tight, we discuss subpanel or service upgrade options before starting the job. This planning step keeps your home safe and your warranty intact.
The disconnect box is one of the most overlooked parts of AC wiring, yet it is critical for service safety. Code requires a means of disconnect within sight of the outdoor condenser, typically a fused or non-fused pull-out switch. We mount this box on a sturdy surface, weatherproof the connections, and use the correct fuse size when applicable. The whip from the disconnect to the condenser is sealed at both ends to keep moisture, insects, and debris out of the unit. Liquidtight flexible conduit is the industry standard for this connection, and we use UL-listed fittings on every job. Bonding lugs inside the disconnect get tied to the equipment grounding conductor for shock protection. Each connection is torqued to manufacturer specifications using a calibrated screwdriver. Loose connections are a leading cause of AC electrical failures, and we eliminate that risk through careful workmanship. The completed disconnect is labeled clearly so future service technicians can shut down power quickly. These small details add up to a system that runs reliably for the life of the equipment.
Thermostat wiring is another piece of the AC system that requires careful attention. Modern smart thermostats often need a common wire, also known as a C-wire, to power the display and communication features. Older homes frequently lack this conductor, which means we run new 18-5 or 18-8 thermostat cable between the air handler and control location. The cable is stapled or stapled-and-stapled to framing per code, keeping it protected from damage. Terminations at the air handler control board are matched to the thermostat’s wiring diagram, eliminating miscommunication between the two devices. We label each wire at both ends with permanent markers or color-coded tags for future reference. Smart thermostat integration is tested before we leave the job site. If your system uses zoning, dampers, or humidity controls, additional conductors may be required. Edinson Electric coordinates with HVAC contractors when needed, keeping the project moving smoothly. The result is a responsive, accurate control system that delivers consistent comfort.
Mini-split installations have grown popular across Hokendauqua and the Lehigh Valley, and the electrical work differs from traditional central air. Each indoor head connects to the outdoor unit through a multi-conductor cable that carries both power and communication signals. We run this cable through a small wall penetration, which is then sealed and protected with a line-set cover. The outdoor condenser still requires a dedicated circuit and disconnect, just like a central system. Single-zone mini-splits often run on 15 or 20 amp circuits, while multi-zone units may need 30 or 40 amps. Voltage requirements vary between 115V and 240V depending on the model, and we verify this before pulling wire. Surge protection at the disconnect is recommended, since electronic boards in mini-splits are sensitive to voltage spikes. We use only manufacturer-approved cable types and fittings to maintain warranty coverage. Inspection-ready workmanship is the standard on every mini-split job we complete. Homeowners get a quiet, efficient cooling system backed by clean, code-compliant wiring.
Older homes in the Lehigh Valley sometimes have electrical panels that cannot support a new central AC installation. Federal Pacific, Zinsco, and undersized split-bus panels are common in homes built before the 1980s. These panels often need replacement before any new AC circuit is added, both for safety and code compliance. Edinson Electric performs full panel evaluations as part of the AC wiring quote process. If a panel upgrade is needed, we include it in the project scope with clear pricing up front. New 200-amp panels with copper bus bars and properly rated breakers handle modern AC loads with ease. We also add whole-house surge protection during panel upgrades, which protects your AC compressor and electronic boards. Permits and inspections are handled by our office, taking that burden off your shoulders. The finished installation is safer, more reliable, and ready for future electrical demands like EV chargers or heat pumps. Every panel upgrade carries our lifetime craftsmanship warranty for added peace of mind.
Outdoor wiring exposed to the elements requires specific materials and methods. Edinson Electric uses UV-rated, sunlight-resistant cable jackets and stainless steel hardware on every exterior installation. Conduit runs are sloped to drain condensation, and weather-tight fittings keep water out of junction boxes. Penetrations through the home’s exterior wall are sealed with code-approved fire caulk and exterior-grade sealant. We mount disconnects high enough to avoid snow drifts but within reach for service technicians. Painted conduit, when requested, blends the installation into your home’s exterior aesthetic. Bonding between the disconnect, condenser, and ground rod is verified with a low-resistance meter. Each component is torqued, tested, and inspected before we close up the job. Our crews leave the work area cleaner than they found it, removing all debris and packaging. These finishing touches reflect our commitment to a five-star service experience.
Safety testing is the final step on every AC wiring job we perform. We use multimeters, clamp meters, and insulation testers to verify voltage, amperage, and circuit integrity. Polarity, grounding, and bonding are all checked before the system is energized. Once power is on, we measure starting amps and running amps to confirm the wire and breaker are correctly sized. Any reading outside the manufacturer’s specifications triggers a deeper diagnostic before the job is closed out. We also test the disconnect operation, GFCI protection where required, and surge device function. Photos of the finished work are saved in your customer file for warranty reference. The homeowner gets a walkthrough explaining the new equipment, breaker location, and how to shut down power in an emergency. This educational step gives you confidence in your new system from day one. Edinson Electric stands behind every connection with our lifetime craftsmanship warranty.

The Importance of a Licensed Electrician for Air Conditioning Wiring in Allentown
Hiring a licensed electrician for air conditioning wiring in Allentown is one of the most important decisions a homeowner or business owner can make. Pennsylvania requires licensed professionals to perform this kind of work because improperly wired AC circuits create serious fire and shock hazards. A licensed electrician understands the latest National Electrical Code requirements and knows how to apply them to your specific installation. Local townships also have their own permit and inspection processes, and a licensed contractor handles that paperwork on your behalf. Insurance companies frequently deny claims for damage caused by unlicensed electrical work, leaving homeowners to absorb the full cost of any incident. Licensed electricians carry liability insurance and workers’ compensation, which protects you if something goes wrong on the job. They also stay current with continuing education requirements that cover new equipment, updated codes, and improved installation methods. Edinson Electrical is fully licensed and insured in the State of Pennsylvania, giving customers the peace of mind that comes with verified credentials. Our lifetime craftsmanship warranty would not be possible without the training and accountability that licensing requires. When the work involves your family’s safety and a major equipment investment, cutting corners is never worth the savings.

Commonly Asked Air Conditioning Wiring Questions
Air conditioning wiring is a service many homeowners only think about when something goes wrong or when new equipment is being installed. The questions below cover the most common concerns we hear from customers in Allentown and the surrounding Lehigh Valley.
Air conditioning wiring costs vary based on the size of the unit, the distance from the electrical panel, and any existing panel limitations. A standard central AC wiring job typically falls between 600 and 1,500 dollars, including the circuit, breaker, disconnect, and whip. Mini-split installations can run a bit lower for single-zone systems and higher for multi-zone setups. Older homes often need additional work, such as panel upgrades or rewiring, which can add 1,500 to 4,500 dollars to the total. Permits and inspection fees are usually included in the quoted price by Edinson Electric. We provide written estimates after a free in-home evaluation, so there are no surprises later. Financing through Synchrony helps spread the cost over manageable monthly payments.
Material costs make up a portion of the total, with copper wire prices fluctuating based on market conditions. Heavier gauge wire, such as 8 AWG or 6 AWG, costs significantly more per foot than 12 or 14 AWG. Long wire runs from the panel to the outdoor condenser also add labor and material to the job. Conduit, fittings, and weatherproof disconnects all factor into the final price. Surge protection upgrades, while optional, add only modestly to the total and protect your investment.
Labor pricing reflects the licensed and insured nature of our crews. Edinson Electric does not cut corners with unlicensed help, and our pricing reflects code-compliant, permitted work. Every job carries a lifetime craftsmanship warranty, which means our work is built to last. Homeowners who compare quotes should verify that other contractors include permits, disconnects, and proper load calculations. The cheapest option often leaves out essential components, which leads to inspection failures or unsafe installations down the road.
Yes, central air conditioners require a dedicated circuit in nearly every case. The National Electrical Code mandates that fixed appliances drawing significant current have their own circuit, free from other loads. Sharing a circuit with other devices causes nuisance breaker trips and creates a fire risk from overheated wiring. The dedicated circuit also protects the AC compressor from voltage drops that shorten its lifespan. Manufacturer warranties typically require dedicated wiring as a condition of coverage. Edinson Electric calculates the correct circuit size before installing any new AC wiring.
The size of the dedicated circuit depends on the unit’s minimum circuit ampacity, listed on the data plate of the condenser. Common sizes range from 15 amps for small mini-splits up to 50 or 60 amps for larger central systems. Wire gauge is selected to match the breaker amperage and run length, following NEC ampacity tables. Voltage is almost always 240 volts for central AC, though smaller mini-splits sometimes use 120 volts. The breaker type, whether standard, HACR-rated, or GFCI, depends on the location and equipment requirements.
Adding a new dedicated circuit means there must be available space and capacity in your electrical panel. Older panels may already be full or under-rated for modern loads. In those cases, a subpanel or full panel upgrade becomes part of the project. Edinson Electric evaluates panel capacity during every AC wiring quote, so you know up front what the job will involve. The result is a safe, code-compliant installation that supports years of reliable cooling.
A dedicated circuit is required for nearly every central air conditioning unit, heat pump, and ductless mini-split system installed today. The National Electrical Code mandates dedicated circuits for fixed appliances of this size because shared circuits cannot safely handle the inrush current of an AC compressor starting up. Inrush current can briefly spike to several times the running amperage, which would trip breakers on shared circuits and shorten the life of other devices on the same line. Window AC units rated under 7.5 amps can sometimes share a circuit, but anything larger needs its own. Dedicated circuits also simplify troubleshooting because a single breaker controls only that one appliance. This is one of those code requirements that exists for very good practical reasons.
The specific size of the dedicated circuit depends on the manufacturer specifications printed on the equipment data plate. Minimum Circuit Ampacity, often abbreviated MCA, tells the electrician what size conductor is required. Maximum Overcurrent Protection, abbreviated MOCP, indicates the largest breaker or fuse that can protect the circuit. We never exceed MOCP because doing so would allow the equipment to draw more current than it was designed to handle. Conductor sizing also accounts for voltage drop over distance, which becomes more important on longer runs. Our team double-checks data plates against existing breakers before energizing any circuit.
Sharing an AC circuit with other loads creates several long-term problems beyond nuisance breaker trips. Voltage sags during compressor startup can affect lighting, electronics, and computer equipment on the same circuit. Continuous overload conditions cause breakers to weaken over time, eventually leading to nuisance trips even at normal operating loads. Heat buildup at terminals from undersized wiring is a known cause of electrical fires in older homes. A properly sized dedicated circuit eliminates all of these concerns. Edinson Electrical installs every AC circuit to code on the first visit, with documentation that satisfies inspectors and insurance companies. Doing it right the first time is always less expensive than fixing problems later.
Wire size for a central air conditioner depends on the amperage rating of the equipment, the length of the conductor run, and the temperature rating of the insulation. Most residential central AC units in the two to three ton range use 10-gauge copper wire on a 30-amp circuit. Larger systems in the four to five ton range typically require 8-gauge copper on a 40-amp or 50-amp circuit. Heat pumps with electric resistance backup heat can require even heavier conductors because total load is calculated differently. Aluminum wire is sometimes used for longer runs to reduce material cost, though it requires anti-oxidant compound and specific termination methods. We verify sizing against the equipment data plate every single time.
Voltage drop calculations matter more than many homeowners realize, especially when the condenser is located far from the panel. Excessive voltage drop causes motors to run hot, draw higher amperage, and fail prematurely. The National Electrical Code recommends keeping voltage drop under three percent on branch circuits, and we design accordingly. On longer runs we sometimes upsize conductors by one gauge to compensate for distance. This small adjustment protects the equipment for its entire service life. Documenting these calculations is part of our standard process.
Temperature rating of the conductor insulation also factors into sizing decisions. THHN-rated conductors are common for indoor runs, while THWN or XHHW are used where moisture exposure is possible. Inside conduit run outdoors or in damp locations, the conductor must be rated for those conditions. We pull copper conductors for AC circuits in nearly all residential applications because copper handles heat better than aluminum and connects more reliably to standard terminals. Wire sizing is one of the technical details that separates code-compliant installations from problematic ones. Edinson Electrical takes the time to do this calculation correctly because the difference shows up in equipment longevity and energy efficiency. Homeowners in Allentown get installations engineered to last.
Pennsylvania law and local township ordinances generally require licensed electricians to perform fixed wiring installations including air conditioning circuits. Homeowner permits are available in some jurisdictions for owner-occupied single-family residences, but the work must still pass inspection and meet code. The technical knowledge required goes well beyond pulling wire and connecting it to a breaker. Properly sizing the conductor, selecting the right breaker, calculating voltage drop, and grounding the system all require training that most homeowners do not have. Mistakes in any of these areas can result in equipment damage, fire risk, or shock hazards. The risk is rarely worth the savings.
Insurance considerations alone make DIY AC wiring a risky proposition for most homeowners. Homeowners’ insurance policies often contain exclusions for damage caused by unlicensed electrical work, even if the homeowner did the work themselves. A fire traced back to a DIY electrical installation can result in a denied claim and significant out-of-pocket loss. Selling the home later can also become complicated when undocumented electrical work is discovered during inspection. Buyers and their inspectors flag non-permitted work, and that often leads to costly remediation before closing. The short-term savings of doing it yourself often disappear quickly when these long-term issues surface.
Even competent DIY enthusiasts often underestimate the complexity of AC wiring because it looks straightforward on the surface. The disconnect placement, conduit type, weatherproofing, and terminal torque specifications all matter. HVAC manufacturers may void equipment warranties when the electrical installation does not meet their specifications. Edinson Electrical handles every detail, pulls the permits, schedules the inspections, and provides documentation for your records. We also back our work with a lifetime craftsmanship warranty that no DIY project can match. For most homeowners in Allentown, hiring a licensed electrician is faster, safer, and more cost-effective in the long run. We make the process simple from start to finish.
A condenser disconnect is a weatherproof switch mounted near the outdoor AC unit that allows electrical power to be safely shut off for service. The National Electrical Code requires a disconnect within sight of the condenser and within fifty feet of it. This is not an optional accessory; it is a code requirement on every modern AC installation. The disconnect provides a clear, accessible way for service technicians to deenergize the equipment without going back inside to find the breaker. It also serves as a safety device during emergencies when the unit needs to be shut down quickly. Skipping the disconnect or installing it incorrectly is a common failure point on inspections.
There are two main types of disconnects used for residential air conditioning: pull-out disconnects and fused disconnects. Pull-out disconnects are simple, reliable, and most common on standard residential installations because the breaker at the panel provides overcurrent protection. Fused disconnects add a second layer of fuse protection at the unit and are sometimes specified by manufacturer or required for longer circuit runs. Both types must be rated for outdoor exposure, NEMA 3R at minimum, to handle weather conditions. We mount disconnects at a height and location that allows easy access for service technicians. Proper mounting includes sealing the back of the box to prevent water intrusion and using approved fittings on conduit entries.
Replacing an old, corroded disconnect during an AC upgrade is one of the most cost-effective preventive measures a homeowner can take. Disconnects exposed to weather for ten or fifteen years often develop internal corrosion that increases resistance and generates heat. A failing disconnect can cause nuisance shutdowns, flickering lights when the AC cycles, or in serious cases an electrical fire at the unit. Edinson Electrical inspects every disconnect during AC service calls and recommends replacement when the existing one shows signs of wear. New disconnects are inexpensive compared to the trouble they prevent. Customers in Allentown appreciate that we look at the whole installation, not just the immediate problem. Our goal is always a complete, code-compliant system that performs reliably for years.
A breaker that trips repeatedly when the AC runs is almost always a sign of a real electrical or mechanical problem, not a faulty breaker. The most common cause is a compressor drawing higher amperage than the circuit can handle, often due to a failing capacitor, dirty condenser coils, or low refrigerant. Each of these conditions forces the compressor to work harder and draw more current, eventually exceeding the breaker rating. A licensed electrician can measure starting amperage and running amperage to confirm whether the electrical load is within specification. If the amperage is high, the issue is mechanical and requires an HVAC technician. If the amperage is normal but the breaker still trips, the breaker itself or a connection along the circuit is failing.
Loose connections at the breaker, disconnect, or condenser terminal block can also cause repeated tripping over time. Loose connections generate heat, and heat weakens the breaker until it trips at lower and lower currents. This kind of failure can be dangerous because the same heat that trips the breaker can also start a fire. Edinson Electrical tests every connection during a diagnostic visit using a thermal camera or infrared thermometer to identify hot spots. Tightening or replacing connections often resolves the problem without replacing the entire breaker or circuit. We also check for damaged insulation along the conductor run that could be causing intermittent grounding.
Ground faults and short circuits are less common but more serious causes of breaker tripping. A ground fault occurs when a hot conductor contacts a grounded surface, while a short circuit involves a hot conductor contacting a neutral. Both conditions cause an instant high-amperage surge that trips the breaker immediately. Damaged conductors, water intrusion at the disconnect, or failed insulation inside the condenser can create these conditions. We use a megohmmeter to test insulation resistance and confirm whether the conductors and equipment are within acceptable limits. Replacing a tripped breaker without finding the root cause is rarely a permanent fix. Edinson Electrical finds the actual problem and corrects it, so the breaker stops tripping and the equipment runs reliably.
Whether to replace your electrical panel during an AC installation depends on the age, condition, and capacity of the existing panel. Panels that are forty years old or older often lack the capacity to support modern AC systems alongside other household loads. Brands like Federal Pacific, Zinsco, and Pushmatic are known to have safety issues and are commonly replaced even when they appear to be working. Adding a new AC circuit to one of these panels is risky and may not pass inspection. A load calculation determines whether the panel can safely support the new equipment along with existing loads. If the calculation shows the panel is overloaded, replacement or a service upgrade is the safest path.
Even on newer panels, available breaker space can be a limiting factor when adding a new AC circuit. A full panel with no open slots requires a tandem breaker, a subpanel, or a panel replacement to accommodate new circuits. Tandem breakers are not allowed in every panel, so this option depends on the manufacturer and model. Subpanels add cost but can be a sensible solution when the main panel has capacity but no space. We discuss all of these options during the estimate so customers can make an informed decision. Sometimes a small upgrade is all that is needed; other times a full replacement is the better long-term investment.
Replacing a panel during an AC installation often makes sense because the work overlaps and bundles labor costs. Pulling permits, scheduling inspections, and coordinating work crews can all be combined into a single project. Modern panels also support smart home features, generator interlocks, and whole-house surge protection more easily than older equipment. Edinson Electrical installs panels from manufacturers known for quality and long-term reliability, including Square D, Eaton, and Siemens. Our installations include accurate panel directories, neat conductor management, and properly torqued connections. Financing through Synchrony makes larger panel-and-AC projects affordable on a monthly basis. We help homeowners in Allentown plan electrical upgrades that support their cooling equipment for decades to come.
