One symptom, many possible causes. That is the core challenge of HVAC repair, and it matters even more in Port Huron, MI, 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 falls behind 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.
Our two most requested repairs are AC Repair and Furnace Repair. That's the place to start if you need a fix today.

- Rising utility costs even though the house feels worse
- Water pooling around the indoor equipment, often from a clogged condensate drain
- Barely any air coming out of the vents
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- A circuit breaker that keeps tripping when the system starts
- Frequent on-off cycling while the house never gets to the thermostat setting
