"Overall pleased with their service. Wish it had been cheaper but who doesn't. The tech was presented with a homeowner installed system done to industry standard and code, and willingly diagnosed and recognized the issues. Repairs successfully applied. The only reason for not giving a full 5 star review is because the tech failed to recognize a missing wire connection in the thermostat and even that barely deserves a 1/2 star demotion as he had the system working correctly upon completion."

"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."

"They serviced my central air conditioning and forced hot air (gas) for the cheapest out of three quotes I received. The tech was super professional and knowledgeable. They gave an awesome report at the end. Would use again for sure!"

"Josh installed a new water heater, provided us with instructions on proper use and maintenance and has serviced it since. He is honest, thorough, and trustworthy. He also maintains my dad’s HVAC needs too. He has come out for emergency calls too. Suggest things to prevent future additional repair expenses. His prices are reasonable, especially for the personal, friendly customer service and service provided. I would highly recommend Northwoods HVAC."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"I called CZ plumbing and Chuck answered the  telephone. I explained that an alarm on the septic pump was indicating malfunction.  He   and Zack came over within an hour of my telephone call.  
They kept us informed of  the repair process from  start  to finish. Great customer service. Fair price. They stand behind their work and I would have them back in a flash. Good people."

FAQs for central a/c service or repair projects in Sanford, ME

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.
