"I found East Coast Comfort for my son’s house when he had heater problems and they fixed his issue quickly and seemed very honest and knowledgeable so then I used them for my house for various smaller jobs and they were always impressive and responsive so when I went to replace my HVAC - I got a quote from them (Ed) which was very reasonable. Lisa remained communicative throughout the entire process. Tony and his team were true professionals. They arrived on time, explained the work to be performed as well as the steps they were taking along the way. They removed the old HVAC system and installed the new one being very careful throughout the entire process. The whole team was friendly and efficient. Ed is also great as he has been to my house for various problems over the years and always does an awesome job. We are extremely satisfied and would highly recommend East Coast Comfort for simple repairs or a full system installation or anything in between!"

"From the person answering the phone to the serviceman, all interactions were polite and professional. They got someone out to check out the problem (water on the basement floor around my a/c unit, which was not cooling well) on the same day I called, during a heat wave. The serviceman did a fair amount of work to find the problem. After he added refrigerant to the system it was working just fine, and with his suggestion I realized I didn't need to have the temperature set as low as I had been doing. The place stayed cool at a higher setting because it was working more efficiently and really pulling the humidity out of the air."

"Initially I had my AC repaired due to a leak. They were upfront about it possibly not holding the Freon..But for a couple of hundred dollars, I wanted to try it over replacing the entire HVAC sysrem. Mine was 33 years old at that point. So the Freon lasted about a month and I said let's just try it one more time and they were willing to try although again they said it probably isn't going to last even with "stop leak" added. Well it lasted about 5 days. So, when I called them to have them install a new HVAC, they took the second service call and credited it to the new HVAC. I have had the new HVAC for about a month, with the Google Nest thermostat and I could not be happier. Tony, JD, Mike and the other guys are the best. Amazing, professional, honest, with a fair to low price. I honestly would have paid more based on other bids. I would say don't even bother with other bids, but that wouldn't he prudent. So, get other bids but go with these guys. I promise you you will not be disappointed. I could not have asked for a better experience!!!"

"I received a finde product and good service from the company. The only issue was the original crew didn't connect the unit to the thermostat correctly and we had one cold night. We called the office and they promptly fixed the issue."

"It went very well. They did a good job. The cost was over $400. I don't know whether or not that's too high or not. I seldom have plumbers in so I can't say the cost was high, although I was surprised it was $400, but that could be the going rate. He seemed very agreeable and very happy. I needed something and he was happy to get it. He was very knowledgeable and helpful in that regard. As for the quality of their service, so far so good. Everything went okay. It stopped leaking."

FAQs for central a/c service or repair projects in Princeton, NJ

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
