Small jobs welcome

"Can’t say enough about how pleased I am with Peter and his crew. Peter worked with me to come up with a solution that fit my needs and stayed within my budget. The work was clean and professional. Absolutely no corners cut. Peter and his crew were friendly and accommodating throughout. I look forward to working with them again year after year for any preventative maintenance or future projects. Will surely be recommending Peter to any friends and family looking to do similar projects."

"Response and repair of my Central Air successfully accomplished all within one hour of placing the call, incredible service! EPA regulations regarding availability of Freon facilitate overpricing of Freon and government controlled price fixing, obviously beyond the control of HVAC Starters."

"The project went well. There were some leaks after the initial installation, but these were fixed before any damage was done to the ceiling and wood flooring."

"Justin and Cam, the technicians, did a great job. We have an old farmhouse with a very strange configuration of partial crawlspace and partial full basement, and water was leaking through the fieldstone foundation wall from the crawlspace. They quickly diagnosed that the problem was coming from 1 or 2 zones of the hot water radiator heating system, and they were able to shut off those zones to stop the leak, while allowing the house to still use water for sinks, toilets, and showers. We'll have to do more work later to replace pipes to the radiator but, because they are hard to access, we need to plan ahead for some construction work. I'm fully satisfied that these guys were able to find the problem and give us even a temporary solution that allows us to have our working plumbing again without the basement getting wet. Would definitely work with them again."

"I've used this company for a few years, beginning with an issue I had where I needed some emergency assistance with an a/c system leaking water into the house. They fixed the issue and it cost far less than I thought it would. I've also used them for a couple heating repairs, annual furnace cleaning and a/c maintenance. I am about to hire them again since the a/c system is dying and it will need replacement since it's more than 20 years old. I would highly recommend Unique Indoor Comfort to anyone in need of a good HVAC/Heating company."

"Palmer Gas has been providing our homes with propane gas and services for over 25 years. The office and customer service staff is courteous and helpful. The installers and repair personnel show up on time and leave the area they are working on cleaner than it was when they started the work. The technicians and repair staff explain what they are doing in a very understandable way. That is important for this of us that are not mechanically oriented. I would recommend the company and staff for your propane needs."

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