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

Every Dungannon service call includes a full diagnostic and a flat written price — with no overtime charge on nights, weekends or holidays.
Dungannon sits in our Virginia service network, and local systems have a specific problem to fight: humid virginia summers and damp winters stress both cooling coils and gas furnaces, and duct leakage in older homes drives energy bills sky-high. Because those failures are predictable, our trucks carry the parts that break first here — which is how we finish most Dungannon repairs in one visit. See our full Virginia coverage.
We serve all of Dungannon and the surrounding Virginia 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 Dungannon Customers Say
Rated 4.9 out of 5 across Google, Facebook and Yelp.
“Best air conditioning repair in Dungannon, 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.Dungannon, VA
“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 Dungannon, VA
“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.”
