Almost every summer breakdown we run in Upland, CA was visible months earlier to anyone holding a meter. A run capacitor reads 8 percent under its rating in April and fails on the first 95-degree afternoon. The refrigerant charge drifts low through a pinhole leak and the system limps a full season before the coil finally freezes. A flame sensor fouls gradually until the furnace picks the coldest night of the year to start locking out. Maintenance exists to catch this arc early, while the repair is cheap and convenient instead of urgent and cold.
Our two most requested repairs are AC Repair and Furnace Repair. If something has stopped working, start there.
Warning Signs for HVAC Maintenance
The sooner you notice these red flags, the easier and cheaper the fix. Keep an eye out for the following clues:
- Musty air when the fan starts, or a filter that has been in far too long
- Nobody has opened up the system in over a year
- A newer unit with warranty terms that call for regular professional service
- Longer run times to get to the thermostat setting
- A surprise breakdown during the last hot or cold spell
- The system sounds different at startup than it did last season
- Utility bills rising even though nothing about your routine changed
- Uncertainty about whether your system is in good shape or on borrowed time
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Call (909) 310-3067 at the first sign of trouble.
