One symptom, many possible causes. That is the core challenge of HVAC repair, and it matters even more in Palatine, IL, 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
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- Rising utility costs even though the house feels worse
- The outdoor unit humming but refusing to actually start
- Grinding, squealing, buzzing, or banging you have not heard before
- Barely any air coming out of the vents
- A circuit breaker that keeps tripping when the system starts
- The system short-cycling on and off without reaching the set temperature
- Water pooling around the indoor equipment, often from a clogged condensate drain
- Air at the registers that is the wrong temperature for the mode you selected
