Find the Fault Before You Replace Parts

HVAC Electrical Diagnostic in Alvin, Pearland & Houston

Alpha Mechanical Air Condition & Heating — HVAC electrical diagnostic for homes and businesses in Alvin, Pearland, Manvel, Friendswood, Houston, and Galveston.

Electrical Diagnostic

A system that is dead, tripping the breaker, or humming without starting is usually electrical. Alpha Mechanical performs HVAC electrical diagnostics with meters—not a parts-cannon—so you pay for the failed component, not a handful of guesses.

What we test on a diagnostic visit

We check incoming voltage, capacitors, contactors, fuses, disconnects, and motor windings. Outdoor units after storms around Galveston and Houston often fail at the capacitor or contactor; indoor units fail at boards and float switches.

You get a clear explanation of what failed, why it failed, and whether a repair or a larger replacement is the smarter spend. Same-day repair is common when parts are on the truck.
