"Outstanding service. I called because my boiler was leaking and the after hours technician responded within 30 minutes of our call. Our coil plate and gasket were rotted and bolts had snapped and we decided that we would replace the boiler because ours was 16 years old. We spoke with the owner and sales manager the following morning and were told that they would be happy to replace the boiler if that is what we wanted to do but they felt our boiler could be repaired at a fraction of the cost and no where near the end of it's usable life. So we decided to go for the repair and they were right, it worked like a charm! So instead of a $9,000 boiler and indirect replacement, we spent $472 and my boiler was up and running the next day. We have used Advanced Mechanical Services for our conversion from oil to natural gas and for our air conditioning installation. They have always been very professional, courteous, prompt and their pricing has always been competitive. I would highly recommend them."

"Everything went well and my family have enough heat for the first time in a two years. Joe knows the heating systems and plumbing very well. He diagnosed the true cause of the problems and replaced the components that need replace. There was no unnecessary work and the cost estimate is very accurate. I highly recommend Joe to anyone who need plumbing or heating system repair or installation."

"So incredibly impressed by Stanley. He called us literally moments after we submitted our HomeAdvisor form. Answered many questions over the phone and clearly is a subject matter expert. Arrived at agreed upon time. Gave us an option to fix the current A/C compressor or replace it. Had it up and running in no time. Would gladly give 10 stars if that option was available. And NO we are not a relative! LOL. What a gem. :)"

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

FAQs for central a/c service or repair projects in Middlefield, CT

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.
