"Terrific experience. Scheduling was easy. My technician, Guy, gave me a call ahead of time, hit the time he said he'd be here and was courteous and efficient. I ran a large mechanical contracting business for years so understand this business. Guy ran through his checks on what is a fairly complex home system. He pointed out problems that were minor, major, or had the potential to be major. We discussed options and timing. Since our system is old, it will be difficult to repair some of the parts and pieces while others would be fairly standard. We may want to look at a new system this summer to avoid a major problem during a future heating season. I will definitely be talking to Sila."

"Joe explained various options (models, efficiency rating, attic vs. cellar installation, etc.) thoroughly, promptly followed through on my follow-up questions, and prepared a detailed & accurate quote. He measured the size of the house and cold-air returns to ensure the system was sized properly. He is a patient guy & very pleasant to work with. Scheduling the installation was painless, the installers (Steve and his assistant Derek) started on time, and worked diligently & efficiently.
Everyone is very experienced and knowledgeable, and all clearly take pride in their work. They kept in excellent communication with me throughout the installation. They were respectful of my home, my concerns, my pets, etc.
They stand by what they sell, too. This winter, about 18 months after it was installed, my tankless hot water heater had a factory defect that caused it to shut off. Steve came the day I reported the problem, was on the phone with the manufacturer for hours to diagnose the issue, and came back twice more to finish the repair (3 visits might sound absurd, but it wasn't Airco's problem, it was the manufacturer's, as they were misdiagnosing the issue). The unit is now working perfectly thanks to Steve's persistence. A bonus: Airco charged me for only a small portion of Steve's time from his initial visit. They ate the cost of his additional visits! These guys are golden.

"everything they did was excellent, their techs are highly trained, they work quickly and the end product for the install looks and works great. They have an annual maintenance contract that covers checkups in the spring for A/C, and the fall for the furnace. Never seen a more thorough report after each checkup. The office staff is very responsive and knowledgeable about all of their services, overall I would say they run a really great operation."

"Atlantic Heating & Air Conditioning responded professionally and quickly to my call. A service technician diagnosed the problem and ordered the a new gas valve and two sensors. A second technician, replaced the defective parts and serviced the boiler. Both technicians performed their work in a very professional manner, identified the source of the problem and clearly explained what was needed. I was impressed with their work and would definitely hire them again."

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