One symptom, many possible causes. That is the central challenge of HVAC repair, and it matters even more in New Braunfels, TX, 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. If something has stopped working, start there.
Warning Signs for HVAC Repair
The sooner you notice these red flags, the easier and cheaper the fix. Here are the most common indicators that it's time to call a professional:
- Unfamiliar sounds from the equipment, like squealing, grinding, or banging
- Utility bills climbing while comfort keeps falling
- Airflow at the registers that feels weak in every room
- Puddles near the furnace or air handler from a blocked drain line
- Air at the registers that is the wrong temperature for the mode you selected
- Repeated breaker trips every time the heating or cooling kicks on
- Frequent on-off cycling while the house never gets to the thermostat setting
- An outside unit that buzzes but will not start
