One symptom, many possible causes. That is the central challenge of HVAC repair, and it matters even more in Dearborn, 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 never catches up is a different list: a weak capacitor, a worn contactor, a low charge, a dirty flame sensor, or a filter clogged badly enough to starve the blower.
The repairs homeowners call us about most are AC Repair and Furnace Repair. Start there if your system isn't running right.
Warning Signs for HVAC Repair
The sooner you notice these red flags, the easier and cheaper the fix. Watch for these telltale signs:
- Vents blowing warm when you want cool, or cool when you want heat
- Water pooling around the indoor equipment, often from a clogged condensate drain
- Rising utility costs even though the house feels worse
- A humming outdoor unit that never kicks on
- Frequent on-off cycling while the house never gets to the thermostat setting
- A circuit breaker that keeps tripping when the system starts
- Barely any air coming out of the vents
- New noises such as grinding, squealing, buzzing, or banging
Early Action Saves Money
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. If you notice any of these signs, call (313) 251-3680 for a prompt inspection.
