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 locks the system out on a frigid night. That is the whole point of maintenance for San Mateo, CA homeowners: find the problem while it is a trend, and fix it on a calm weekday rather than as a crisis.
Most of our service calls are for AC Repair and Furnace Repair. That's the place to start if you need a fix today.
