"I bought my unit from NETR in 2018. It worked fine until we discovered it wasn't blowing any cold air. I made the big mistake of hiring someone a family friend recommended and they diagnosed it incorrectly and then basically disappeared on me. Anyway, it took a few weeks but they repaired it today and I was impressed with their courtesy and getting the job done very quickly and successfully. I felt like I was being dealt with honestly. Thanks, Jared and Jack. I should mention I paid about $300 for the refrigerant today. I don't know what the final cost will be but probably a bit over $1000."

"I had originally thought that a high velocity mini-duct central a/c system was the only option for my Victorian home with baseboard heating. But when Joe Carnevale from Airco explained the benefits of a multi-zone slim-duct system with concealed air handlers in the attic to cool the second and third floors and a conventional system tied to existing (unused) floor registers on the first floor, I was intrigued. After rebates and tax credits (which aren?t available for high velocity systems) the cost was extremely competitive and the fact that the system has four individually controlled zones means that I can adjust the cooling levels to keep operating costs lower. The installation was a little tricky as I asked (owner) Steve Duarte and his crew to run the refrigerant, electrical, and condensate lines through an unused chase to the second and third floors rather than affix a conduit to the outside of the house (which wouldn?t have been allowed due to my home?s historic designation.) The work was done efficiently and with practically no disruption to the day-to-day living that went on during the installation. The left the house and basement very clean. I have been very satisfied with the system?s performance during the several heat waves we?ve experienced this summer. All in all it was a very professional job from start to finish and I would highly recommend Airco Home Comfort Services to anyone considering central air conditioning, and in particular to owners of older homes without existing ductwork.

Small jobs welcome

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

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