HOME / HEATING REPAIR
Heating repair in Southeast Texas commonly involves a gas furnace, electric air handler with heat strips, or heat pump. Blast Mechanical diagnoses residential heating failures across East Houston, the Clear Lake/NASA Corridor, and mainland Galveston County, then explains the repair before authorized work begins.
Call when the system will not start, the thermostat calls for heat but supply air stays cold, the unit starts and stops repeatedly, airflow drops, auxiliary heat runs unusually often, the outdoor heat-pump unit ices excessively, or the furnace produces abnormal ignition or blower noises.
A gas furnace may have an ignition, flame-sensing, pressure-switch, limit-switch, venting, gas-control, or blower issue. A heat pump may have a refrigeration, reversing-valve, defrost-control, outdoor-fan, thermostat, auxiliary-heat, or airflow issue. Diagnosis begins by identifying the system type and operating sequence.
A gas smell, carbon monoxide alarm, or scorched-smelling furnace is not a routine repair call. See when a heating problem shouldn't wait for what to do first.
A gas furnace may be running the blower without establishing or maintaining flame, while a heat pump may be in defrost, operating with failed auxiliary heat, or experiencing a refrigeration or control problem. The system type and operating sequence determine the diagnosis.
A fall inspection is a practical way to check heating operation before colder weather. Homes with a heat pump also benefit from a spring cooling visit because the same refrigeration system operates in both seasons.
Auxiliary heat can operate normally when outdoor conditions or thermostat demand require extra capacity. Emergency heat is a manual setting that bypasses normal heat-pump heating. Frequent or unexpected auxiliary-heat operation can also signal a thermostat, defrost, airflow, refrigeration, or heat-strip issue.
