"Royal Comfort was one of the three contractors that responded to my repair request. The company provides prompt and responsive service. Technicians are knowledgeable, trustworthy, professional and courteous. Jesse is honest, no pressure and easy to work with and doesn't try to upsell something that you don't need. Kudos to Hugo and the team. Highly recommend and would use them again."

"Inspection and work performed was extremely thorough, well communicated throughout the job so I could understand the status and look to the future of our units. He also allowed me the opportunity to look at what he had done, and what the duct cleaning company had or had not done. Specialist (Dennis) offered me a very reasonable service plan for the season that seemed very good value and which I paid for."

"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."

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"Dave (service manager) is friendly, honest, and very knowledgeable. I needed the smoke pipe replaced on my gas furnace, along with some routine maintenance, and he contacted me shortly after I posted the job. He gave me a free estimate the next day, which included itemized costs of all the labor and each of the parts needed. He and his colleague finished the job quickly and cleaned the area up when they were done. The cost was exactly what he quoted. I will be using them from now on for all my heating and cooling repairs and maintenance."

FAQs for central a/c service or repair projects in Katonah, NY

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.
