We have years of experience in the business! Here at Hornets Heating & Cooling we pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!

"Hornet?s Heating and Cooling replaced and installed a new outside unit 7 years ago and replaced the evaporator coils on the unit in my attic. This weekend my ac stopped working and I had another HVAC company come out to diagnosis. I provided paperwork from Hornets that I have a 10 year manufacturing warranty and a 5 year warranty on certain parts. After their diagnosis, they informed me the evaporator coils were damaged and that old parts were used. The outside unit was a 2018 model, but the parts were from 2014. Not only were old parts used, Hornets did not register the parts, therefore voiding the warranty, as well as the installation of the outside unit was of poor work. Now I'm having to pay another HVAC company to replace a unit that typically should have a usefulness of at least 10 years. I would give them 0 stars, but I have to give 1 in order to post this review."

FAQs for central a/c service or repair projects in Denver, NC

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.
