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 losing charge 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. Maintenance is built around this reality for Vancouver, WA 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. Start there if your system isn't running right.
Warning Signs for HVAC Maintenance
Catching these issues early helps you avoid costly problems. These are the signals our technicians see most often:
- Filters you cannot remember changing, or a musty smell when the blower starts
- A startup sound that has changed since last year
- Energy bills creeping up without any change in your habits
- Cooling or heating that takes noticeably longer to reach the setpoint
- It has been more than a year since anyone opened the equipment
- A surprise breakdown during the last hot or cold spell
- Uncertainty about whether your system is in good shape or on borrowed time
- A newer system whose warranty terms expect documented maintenance
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. If you notice any of these signs, call (971) 535-9388 for a prompt inspection.
