"The team of 3 arrived as promised! They set up the work station by spreading cover on the floor to protect my tiles. That was very satisfying to me. They were actually busy working diligently throughout the day. They provided 3 space heaters for my use if I needed. I was informed of what was going on that needed my attention. The end product seemed very good although it is too early to judge its quality. This review would have been rated with 5 stars, but I have concerns in some areas. First, the height of the exhaust pipe was shorter than I had expected. Their reasoning for not raising the exhaust pipe is not accurate. They claimed my windows were in the way. There is a clear pathway to place the the pipe if they had wanted. I’m still concerned about the exhaust fumes entering my living room if the window is open. I was told quality inspection would be performed, that has not happened yet. I hope it happens! Second, the thermostat wiring on the second floor or zone 3 does not have common wire C. The bypass that was installed in the Teco relay system didn’t work. It worked briefly for short time and then stopped. When I contacted the sales agent, he referred me to the office to explain my issue. I thought he was going to take me out of the loop as most customer satisfaction oriented company would have done. I complied and the customer service office referred me back to the same person! When the he got back to me, it was more in defense than empathy. He tried erroneously to cast the blame on my supplied thermostat, which was not involved. Eventually, he sent someone who was able to fix the problem. Third, the sales agent didn’t provide the most critical info on the contract form, the AHRI number. This number is needed for MassSave loan application. He provided it later. So far, the Lennox hot water and boiler combi and my 3 google nest learning thermostats are working very well. Even with the stated issues, I would definitely recommend ARS Rescue Rooter for providing a good product at a fair price. This company has the potential to leap frog competition to become the leader provider in this industry. If only it implements hassle free procedures for its customers."

"Even though our furnace died (it was old) still have to commend the professional, knowledgeable and kind staff at Green Energy who not only came over immediately to render assistance but also brought us space heaters while we wait for them to install our new system. Irvin lightened the mood and answered all our questions while helping us understand the issue and pick the best next solution. Terry was awesome since day 1 and both have been great with our kid ð ¶. Thanks Irvin & Terry!! -Lisa"

"Jake Souza is professional, friendly, knowledgeable, and accurate. He arrived on time, pinpointed the problems with the unit, and gave me payment options. He gave me hints on how to keep the unit running in great condition, such as shutting it off when the lawn is mowed, because it can suck in unwanted debris. Cover the top of the unit for the winter to keep anything from entering it. Rinse the sides of the unit lightly with a hose to remove debris from vent openings. I am very satisfied with the work this professional did on my central air conditioning."

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