"I whole heartedly recommend Airco. Their team was experienced, skillful, friendly and professional throughout the duration of this job, from Joe's first visit to my home to discuss air conditioning options to Derek and Cam's final touches on the duct system. I had complete confidence in them, as well as in Steve, Danny, Frank and Patrick. Additionally, Airco's connections to MassSave and Commerce Bank meant financing and payment options to suit my budget. No more hauling loud and heavy window a.c. units up from the basement. Instead, I am enjoying consistent cooling throughout my home with no noise whatsoever. I am a very happy customer!"

"They were extremely responsive and professional. Someone was dispatched to my home within 24 hours. He accurately diagnosed the problem - that the condensate pump had failed and needed to be replaced. He offered to replace it immediately because he had the part on his truck. The price quote ranged from $1350-$2100 depending on length of warranty I preferred. This seemed extremely high because I had the part replaced once before 3-4 years ago by another company for approx $400. I mentioned that to the installer; he indicated that the price was the price and he was sorry he couldn’t lower it. I found the identical pump online for prices ranging from $35-$75! It looked like an easy swap, so instead of paying Rodenhiser, I ordered the part from Amazon, received it the next day. I have zero experience or training and was able to swap it and fix the problem in literally 10 minutes. I understand that service companies need to charge for labor and mark up parts costs, but a repair I could do in 10 mins for under $50 should not have carried a $1350+ price tag! This was very disappointing, and I will not use them again."

"Dan Thompson, was very thorough and accommodating with repairing my furnace. I appreciate his attention to detail and all the work of the other ARS contractors that replaced my furnace and thermostat. Will be using ARS services in the future!"

"Contacted company to obtain estimate along with other companies. Darren was very responsive even though he was headed out on vacation for a long weekend. He did follow-up with email to make sure I understand his proposal which none of the other companies did that provided an estimate. I did contract with Atlantic to replace my old system which was 20+ years old. They came to the house (Darren, Liam and Adam) before starting the work so they could review the plans for starting the following Monday. They did confirm everything with me including the start time. I was contacted at the end of each day with an updated status on the work. The job took two and 1/2 days to complete and the basement was left clean after their work. Communication was excellent as well as explaining what they may need to do in the basement to ensure that everything was up to current code. Both Liam and Adam were professional and polite."

Customers say: Quality work

"Really terrific work and attention to detail. Derek and his crew are obviously super knowledgeable and professional and did not in any way try to oversell or up-sell us (Derek even told me how to clean the condenser unit in the springtime myself). The install (of a combined propane furnace and central A/C) took place just days after I first spoke with Derek, and involved minimal downtime while the old system was swapped out for the new one. I would recommend DG without reservation to friends and family (and strangers)!"

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.
