One symptom, many possible causes. That is the core challenge of HVAC repair, and it matters even more in Rialto, CA, where failures seem to wait for the most extreme weather of the year. Equipment that will not start at all might have a failed low-voltage transformer, a thermostat that has stopped calling, a control board that has lost its sequence, or a float switch shut off by a backed-up condensate drain. Equipment that runs but never catches up is a different list: a weak capacitor, a worn contactor, a low charge, a dirty flame sensor, or a clogged filter choking off the blower.
Most of our service calls are for AC Repair and Furnace Repair. Start there if your system isn't running right.
