Residential Mechanical Systems Installer (Heating & Cooling)

Build comfort. Build your career.

Picture this: A homeowner in Greater Hartford finally replaces an aging system. You arrive in a fully stocked company truck, remove the old unit, set a high-efficiency furnace or heat pump, fine-tune the air handler and duct connections, program the thermostat, and complete startup and testing. Everything meets code, aligns with manufacturer requirements, and reflects the quality standard you take pride in. That’s your everyday impact at One Hour Heating & Air Conditioning.
