"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"I am a long time customer who pays Rodenheiser a monthly fee which covers annual maintenance and some priority in the event of any necessary repair required. I had an a/c compressor failure. I had to wait 3 weeks to have a technician visit and tell me that the unit’s motor was dead and the compressor needed replacement. Then, after ordering a new compressor, which was available within 3-4 days I was scheduled for an installation 3+ weeks later. I had to complain strenuously and threaten to cancel the order to get the installation moved forward to within 10 days. Apparently being a long time customer and paying a monthly fee for better service means absolutely nothing. The installation went well. Not sure about future relationship."

Small jobs welcome

"My central AC system had gone several years without service so I wanted it brought back to peak efficiency and this is exactly what Jay did. After changing some parts and cleaning it, he pronounced it as running perfectly. Jay was very friendly, courteous and professional and his can-do philosophy assured me that the system would be running well and I could depend on them to keep it that way."

"First off, the consult was great. I was able to add services to my initial request and received a deal doing so. I also added a second set of services later that month. Adam and Steve completed the work and were completely professional and super efficient. They answered my questions and made sure I understood the work being performed. They worked with my schedule and were fantastic. I had a gas hook-up for a change from electric stove to gas stove - they even took care of the permits and inspection. They removed an old water access point for the fridge's icemaker that was in an awkward spot. They also added a regulator for the water pressure and water filtration system. Fantastic work all around. Should we need any more plumbing/gas work, I would definitely hire them again."

FAQs for central a/c service or repair projects in Ayer, MA

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.
