If you could look at the readings, you would see most failures coming a season in advance. A capacitor measuring 8 percent under its rating in spring is the one that fails in the first heat wave. A system bleeding refrigerant through a pinhole leak keeps running, weaker each week, until the coil freezes solid. A furnace flame sensor fouls slowly and then shuts the furnace down on a frigid night. That is the whole point of maintenance for Fairfield, CA homeowners: find the problem while it is a trend, and fix it on a calm weekday instead of in an emergency.
Our two most requested repairs are AC Repair and Furnace Repair. Start there if your system isn't running right.
Warning Signs for HVAC Maintenance
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- A newer system whose warranty terms expect documented maintenance
- Uncertainty about whether your system is in good shape or on borrowed time
- Longer run times to get to the thermostat setting
- The system sounds different at startup than it did last season
- Nobody has opened up the system in over a year
- A surprise breakdown during the last hot or cold spell
- Filters you cannot remember changing, or a musty smell when the blower starts
- Energy bills creeping up without any change in your habits
Act Before It Gets Worse
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Call (707) 210-0161 at the first sign of trouble.
