"Wonderful. Dave kindly walked me through the reset process on the phone and did not need to come out to service the water heater. I will be calling him in the future for any needed repairs."

"Rays HVAC tech came in and evaluated the problem with the A/C (early Sept. 2020). The coil was freezing up and dripping water. Another company wanted to replace the coil for over $3,000. Rays said it just needed free-on. Topped it off for $200 and the system ran fine after the service. would highly recommend it. Used Rays HVAC for a heating issue March 2021. Ray was quickly reachable, great communication, came the next afternoon. Great job on the repair and for a very good price."

"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."

"I could not be more satisfied with the work I just recently had done by AAA HVAC. I was first very satisfied and agreed with the quote for the work and was scheduled for the very next day. I quickly realized these guys meant business . They went right to work to replace my boiler and hot water heater. If you are looking for fast and top notch work, then do yourself a favor and give these guys a call they are experts at what they do and you will see for yourself. I also have an old central air system and when need be , I know who to call. Thank you guys for a great job that looks great too !"

"

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.

"Excellent! The team worked diligently for 5 days to install a central air system in our old house with Plaster Walls. It was NOT easy, yet they did a fantastic job. They were able to add all ducts to the first floor with out any "chases" or enclosures requiring to be build. And almost none of our first floor lines up with our second floor closets, but they figured it out. Great time and fantastic service. Make sure you get Brandon and Sean. The work their butts off, and ensure your house stays clean (they cleaned up everything after every day - not an easy feat). Cannot say how happy am I with their work!"

"Our oil burner began emitting Carbon monoxide (CO) early one morning and stopped working. We called several repair services and no one called us back in a timely manner. We found AB Castello's on Angie's List, completed the Angie's List form and Desmond from AB Castellos called us immediately. Robert arrived less than an hour later. The first thing he did when he arrived was check for CO emissions. He then determined that our 16 year old furnace needed to be replaced. Later that day we received an estimate via email, had all of our questions answered on the phone, and arrived the next morning prepared to remove and replace our furnace. Desmond and Robert worked all day, into the evening, in order to install the new furnace. They were determined not to leave us one more night without heat. They were very polite, pleasant, neat and did an excellent job. I would highly recommend this company should you need service of any kind. Their response time was better than almost any other contractor we have hired, and their work excellent. They also cleaned up very well before leaving our home, and were very careful as they carried equipment in and out of our house. I cannot speak highly enough of them"

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