What Heating Services technicians do
Heating technicians are licensed professionals who service gas furnaces, oil boilers, heat pumps, and radiant heating systems under local mechanical codes. Their inspection process includes combustion analysis—measuring CO concentration and flue draft to verify heat exchanger integrity—followed by gas pressure and manifold pressure tests at the valve train. Technicians check flame sensor resistance, inducer motor amperage, and ignition timing before running a full heat cycle, then document AFUE performance and carbon monoxide safety readings as part of every service record.
