"Jason is a great guy very honest, quoted me a price and when his crew was done they all checked to make sure my ac was up and running . No hidden fees or extra charges. Arrived at the time we set and got right to work finished the job on the same day. Called me the next day to make sure I was happy. Iâ  m very happy. I would recommend him to anyone looking to replace their unit, very reasonable priced. Thank you very much Florida Air conditioning."

"It was absolutely amazing to work with E Z air conditioning. He was on time to the appointment and was very clear about what work needed to be done and how much it would cost. When it came to pricing, he was willing to present all the details to me with such clarity that I didn’t feel like he was hiding anything. His candid way of communicating makes you feel like you’re just chatting with a normal person and not a slimy sales guy. The work took about 2 hours and it was worth every penny. Peace of mind and quality work. Thank you E Z Air!!!"

"After having another company tell me it was a Reverse Valve issue and pretty much said "good luck" as he left, I called Fenwick/Weychoff and they had a tech out by 9pm same day. The tech, Mark Wesley, not only fixed a simple issue and got my house cool that same day, but only charged me the base price for the service call. It ended up being an issue with the thermostat. Nothing wrong with the reverse valve. Thanks, Mark, and thanks, Angi, for recommending Fenwick/Weychoff! Respectful and honest. They've got my business from now on!"

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