Family owned and operated since 1969, Grant Heating & Cooling is a knowledgeable and dependable resource for meeting all your comfort needs. Contact us for installation, maintenance or service

"I contracted with Grant Heating & Cooling Inc. to install HVAC system in my home in the spring of 2024. They were very professional and did a very good job. In the winter of 2025 I had a minor problem with one of the Mitsubishi heat pump system units. The company was quick to troubleshoot the situation. The technicians were courteous, knowledgeable about the system and thorough. It required several visits to diagnose the problem and fix it. The manager, Nick was very responsive to the situation which required bringing out an expert from Mitsubishi. All of this work was covered under my warranty. The problem was fixed and I could not speak highly enough about the company’s policies and customer service. I would highly recommend them for all facets of their work and standing behind their installations. I am very happy to be working with them for my continued maintenance. They are an excellent company. Sincerely, Susan Coursey"

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

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