"The gentleman from Kingdom surpassed every other furnace service that we have EVER had. He called within 10 minutes of our request on home advisor promised to be here within an hour and he arrived 45 minutes later. He diagnosed the problem with our furnace went to the store and returned with a new pressure release valve within a half hour. Installed it tested it, bled the lines which immediately improved the heat in a cold bedroom. I can't say enough about how totally excellent this repair man was if I could give 10 stars I would."

"Through the several steps of getting this generator project done Palmer was on time and on task always. Their communication is outstanding from Michelle's initial visit and proposals through tank delivery by Corey and most centrally through all of Steve's installation work and coordination with inspectors, electricians and me. Two weeks later first power outage and everything worked like a charm. I just started with Palmer four months ago and added oil delivery and service to my generator work and I've been pleased with everything in the office and field. Very grateful."

"Recently had Kyle's cooling and heating out to replace my furnace and central Ac system. Could not have been happier with the process from getting a quote for replacement to scheduling to the install itself. Kyle was very informative on any questions I had and I will certainly be using this company to perform the yearly service on my new hvac system. Highly recommend!"

FAQs for central a/c service or repair projects in East-derry, NH

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.
