"Ken has an eye for detail and he was able to articulate repairs need to keep your unit running for the long term. His work leaves no stone left unturned and his repair recommendations are based on integrity. I was very happy with the maintenance work and the additional repair that was required. I plan to have him back for because he gave me a fair price on a UV light and air purifier."

"Fontana Brothers installed my new Bosch HVAC system, and I couldn’t be happier with the experience. Freddie and Shaquille arrived exactly on time, worked efficiently, and left the work area cleaner than it was before they began. Their attention to detail and professionalism were outstanding. As a Realtor for more than 30 years, I’ve dealt with many HVAC companies, and Fontana Brothers continues to be one of the very best. They consistently deliver excellent service to both me and my clients, and their pricing remains highly competitive. I trust them completely with my referrals. Special thanks to Dan Fontana, who heads the service department — always organized, responsive, and helpful — as well as the entire office staff, who are consistently friendly and a pleasure to work with. I will absolutely continue to recommend Fontana Brothers to others seeking HVAC installation, repair, or replacement."

"Quick service. Very professional tech (John) explained his findings and the repairs need to solve the problem. He also explained what was needed to prevent future problems. We decided on a plan to get the work done. John had all the parts needed in his van and the work was completed in a timely fashion the same day. We are highly pleased with PLAN B A/C service and will use them again in the future."

"I couldn?t be happier with my experience with Three Guys AC! They recently repaired my heat pump, and the whole process was smooth, professional, and stress-free. The technician was extremely knowledgeable, showed up on time, and took the time to explain everything to me clearly. My system is running perfectly now, and the quality of their work really shows. It?s rare to find a company that combines honesty, skill, and great customer service the way they do. I?ll definitely be using Three Guys AC for all my future HVAC needs ? highly recommend!"

"I have ARS do all my A/C work. This was actually for a maintenance check of the system. Technician, Flogert Mihaj, is very nice, respected my property, knowledgeable, and explained what was or wasn’t found. Their customer service people, Madison, made sure I had Flogert come, as I’ve dealt with him many times before."

FAQs for central a/c service or repair projects in Dover, FL

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.
