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. That is the whole point of maintenance for Seattle, WA homeowners: find the problem while it is a trend, and fix it on a calm weekday instead of in an emergency.
Most of our service calls are for 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:
- A breakdown last season that arrived with zero warning
- Energy bills creeping up without any change in your habits
- A newer system whose warranty terms expect documented maintenance
- The house taking longer to reach the temperature you set
- No real sense of how healthy your heating and cooling equipment is
- A filter you cannot recall replacing, or a musty odor at blower startup
- A startup sound that has changed since last year
- Nobody has opened up the system in over a year
Don't Wait for a Total Failure
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Don't wait, call (425) 969-3321 and we'll take a look right away.
