"Sam and AJ are the best! Submitted a request on Angi yesterday afternoon, received an immediate call back saying they could be here within 2 hours to diagnose an issue with our central A/C air handler in our attic. AJ was here promptly, and immediately went to work systematically checking through each part of the system. Side note - it must have been 115 degrees in the attic while he was working, didn't seem to bother him at all! Within 2 hours, he had identified a failed motor, sourced the parts, and gotten me a very reasonable quote for replacement. Parts arrived the next day, when he and Sam came out to install, got the whole system back up and running normally, and cleaned up. They did the job for the price they quoted, in the time they quoted it, without trying to sell me an entire new A/C system.... can't tell you how much that's appreciated. First time customer, but will definitely be using them for our boiler service as well. Fantastic service. Could not be happier I found them."

"Isaiah, the service technician from Ray’s, did routine annual maintenance on my central air. My prior contractor retired and I had not had this done in a couple of years. Isaiah was through and answered my questions and concerns. I will be happy to use Ray’s services again."

"I recently hired Kyle to service my central air conditioner. What a find!!!! I will absolutely hire him again. He is bright, personable and explains every step of his process. You can tell he is passionate about HVAC, and enjoys his work. He was able to quickly evaluate my system and get it back up and running. My system is old and really needs to be replace but Kyle was able to keep in running for another year... Highly recommend this company"

"Excellent service - arrived on time and completed within estimate. Joey was my technician he could not be any more professional or efficient. Valentina handled my emergency call early on a Sunday morning and by the early afternoon I had everything back to normal. Couldn’t be more pleased with the services performed, or the professionals involved. No need to look any further, this is the place to call."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"We have relied on ABCastello to service our furnace for several years. Recently our CO detector went off, and they arrived in a very timely manner to evaluate the issue. As seniors, heat is a top winter necessary. They were able to make the necessary repair the same day! Not only did they provide excellent service, but they are polite and leave the area clean. What more can you ask for. It is a real pleasure to know our furnace is always in such good hands. Needless to say, we would highly recommend them. Thank you, Desmond and Rob!"

FAQs for central a/c service or repair projects in Cedar Knolls, 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.
