If you’ve lived in Gainesville for more than one summer, you already know the deal. The humidity rolls in, the AC runs hard, and when something goes wrong, the whole house feels 20 degrees too hot in about an hour. That’s where we come in.
Res Air Heating & Cooling has been helping Gainesville homeowners and small businesses keep their air conditioners, heat pumps, and furnaces running for years now, and we’ve built our reputation the old-fashioned way: by showing up on time, doing the job right, and not nickel-and-diming people on parts they didn’t need.

A Bit About Gainesville
Gainesville wears a lot of hats. It’s a college town, sure. The University of Florida shapes a huge part of life here, and Saturdays in the fall belong to the Gators. But it’s also home to families who’ve been here for generations, retirees who came for the weather, and a steady stream of new residents drawn by the nature, the food scene, and the easy pace of life. There are afternoons spent at Paynes Prairie, weekends at Ginnie Springs, and quiet walks through the old oak-lined streets of Duckpond.
What no one tells you when you move here is how hard the climate can be on HVAC equipment. The heat is one thing. The humidity is the real problem. Air conditioners run almost year-round, and when winter does show up, it gets cold enough that you’ll be glad to have a working heater on hand. Skip the maintenance, and a Gainesville summer will find every weak point in your system.

What We Do
We handle pretty much everything on the residential and light commercial side. Here’s the rundown.
- Air Conditioning — Sales, service, the works. Most of our calls involve AC, and we know these systems inside and out.
- AC Repair — If your unit is making weird noises, blowing warm air, leaking water, or just not keeping up, give us a call before it quits on you completely.
- AC Installation and Replacement — When it's time for a new system, we'll size it right for your home and install it the way the manufacturer intended. No shortcuts.
- AC Maintenance — One tune-up a year keeps most major problems at bay. It's the easiest money you'll ever spend on your house.
- Heat Pump Services — Heat pumps make a lot of sense in this part of Florida. One unit, both seasons. We install, service, and tune them up.
- Heat Pump Repair — When something's off with a heat pump, the symptoms can be tricky to read. We'll figure out what's actually wrong instead of swapping parts and hoping for the best.
- Heat Pump Installation and Replacement — A modern heat pump can save you real money every month. If yours is more than a decade old, it's worth a conversation.
- Heating Services — It doesn't get cold often around here, but when it does, you want the heat to work. We've got it covered.
- Furnace Repair, Replacement, and Installation — Gas or electric, old or new, we'll keep yours safe and running. And when it's time for a new one, we'll walk you through your options without the hard sell.
- Mini Split Services — Got a sunroom that's always too hot? An addition that isn't on the central system? A garage you'd actually like to use in July? Mini splits are the answer, and we install them all the time.
- Indoor Air Quality — Pollen, pet hair, humidity, mold. There's a lot going on in the Florida air. We offer purifiers, dehumidifiers, UV lights, and ventilation upgrades to clean it up.
- Full HVAC Services — Anything that doesn't fit neatly into one of the boxes above, we probably do. Just ask.
