Your Key Biscayne, Florida Air Conditioning & Heating Company
Connected Air Conditioning & Heating has become a go-to HVAC company in Key Biscayne, FL for one simple reason: we show up fast, quote the price before we start, and fix it right the first time.

Key Biscayne sits in our Florida service network, and local systems have a specific problem to fight: year-round florida humidity keeps air conditioners running nearly 12 months a year, so drain-line clogs, frozen coils and worn blower motors are the #1 emergency calls. Because those failures are predictable, our trucks carry the parts that break first here — which is how we finish most Key Biscayne repairs in one visit. See our full Florida coverage.
We serve all of Key Biscayne and the surrounding Florida communities: older established neighborhoods running 20-year-old equipment and undersized ductwork, newer subdivisions where builder-grade systems are already failing, plus offices, restaurants and warehouses that need commercial HVAC repair.

What Key Biscayne Customers Say
Rated 4.9 out of 5 across Google, Facebook and Yelp.
“Best air conditioning repair in Key Biscayne, hands down. Three companies quoted a full system replacement. These guys found a bad contactor, fixed it for a couple hundred dollars, and told me the system had years left. Honest people.”
Danielle R.Key Biscayne, FL
“Furnace quit on the coldest night of the year. They answered on the second ring at 2am and had heat restored by 4am. I've never had a contractor take a no-heat call that seriously.”
Tony V.Near Key Biscayne, FL
“Full system replacement — new furnace and AC. Crew showed up on time, laid down drop cloths, finished in one day and walked me through the new thermostat. Our upstairs is finally comfortable.”
