HOME / AC SERVICES / AC REPAIR
Residential AC repair starts with finding why the system is not cooling, not with replacing parts at random. Blast Mechanical diagnoses central split systems and heat pumps for homeowners across East Houston, the Clear Lake/NASA Corridor, and mainland Galveston County, then explains the repair before authorized work begins.
Common calls include warm supply air, weak airflow, short cycling, a frozen evaporator coil, water around the indoor unit, unusual compressor or blower noise, a tripped breaker, and an outdoor unit that will not start. The cause may involve a capacitor, contactor, fan motor, blower, thermostat, safety switch, condensate drain, refrigerant circuit, compressor, evaporator coil, or condenser coil. Testing determines which component is actually responsible.
In the Gulf Coast climate, an AC system must remove heat and moisture. A system can reach the thermostat setting and still leave the house humid when airflow, equipment sizing, run time, drainage, or system operation is wrong. Diagnosis should consider temperature change, airflow, coil condition, condensate removal, and indoor humidity together.
If your AC has stopped entirely or you're seeing signs like water intrusion or an electrical smell, see when an HVAC problem shouldn't wait for guidance on what to do next.
There is no single age or cost rule that decides every case. The decision should consider the failed component, total repair cost, system condition, refrigerant type, efficiency, comfort history, and whether the indoor and outdoor equipment remain a compatible matched system. Blast Mechanical will explain both paths when replacement deserves consideration.

Warm air, weak airflow, repeated starts and stops, ice on the refrigerant line, water near the air handler, unusual electrical or mechanical noises, and a sudden change in cooling performance all justify a diagnostic visit.
Often, yes. Repairability depends on the leak or failed component, parts availability, refrigerant requirements, system condition, and cost. New residential equipment is moving to lower-GWP refrigerants, but an existing system should be evaluated on its actual condition rather than replaced solely because its refrigerant is older.
