"Totally excellent service. My furnace was not working so I had no hot water. I called after 7 pm and Mike was there first thing in the morning to check it out. He located the problem and took immediate action to resolve it. Called suppliers, located the part for a 57 year old furnace. The following day Jason and Chase came and made the repair. Cost effective price with professional workmanship. Reliable and trustworthy."

"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."

"Very well. I felt Craig was very professional and very knowledgeable. I think the previous company did me a favor when I was told they couldn’t service my boiler any longer"

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