No-Heat Calls, Answered Day or Night

When the heat dies in a Durham home, every hour counts. We respond around the clock to gas and oil furnaces, boilers, and heat pumps that have quit, tracking down failed ignitors, locked-out controls, dead blower motors, and seized circulators. If the trouble points to a cracked heat exchanger, we shut the unit down and explain the carbon monoxide risk before anything else.

Summer breakdowns are just as urgent, especially for households with seniors or young children. We restore cooling fast in Durham, handling refrigerant leaks, failed compressors, blown capacitors, and frozen coils on every major brand, including Lennox, Carrier, Trane, and Goodman. Our trucks carry the common parts so most emergency repairs wrap in a single visit.
