"Eric and his Installers were so nice and respectful.. they showed up to the job at 8 am (exactly when they said they would) they installed a new Rheen central air system in my house. They did an amazing job especially since the weather was so bad that day. it poured rain all day, but that did not slow them down.. they did not rush or cut corners and the work was done right.. they even took the time to answer all my questions and show me all they did and explain the good and bad of the installation.. they were very clean and did not leave a mess.. very reasonably priced too. I would definitely recommend them to anyone I know... Thank you again, Eric. Fantastic Job."

"Billy was great from start to finish. So pleasant, so patient, and very thorough! He explained everything and even checked in after the work was completed to make sure the central air was working well. Would definitely recommend for AC repair and will use him again in the future!"

"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

"Vinny and his son arrived at my house at 8:45am on Friday, 15 minutes earlier than expected (a pleasant surprise). He stuck to the price quote he gave me 8 months earlier. Their work was thorough, neat, clean and of excellent quality. The new central A/C unit is quiet and efficient. I will use them going forward to maintain and service my A/C unit as well as my furnace. I referred them to my neighbor across the street who is looking to get a new central A/C unit next year. I strongly recommend them to anyone who is looking to service or get a new central A/C unit, furnace, hot water heater, etc. You wont be disappointed. He is a man of his word."

FAQs for central a/c service or repair projects in Port Jefferson, NY

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.
