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. Maintenance is built around this reality for Plymouth, MN 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
Catching these issues early helps you avoid costly problems. Watch for these telltale signs:
- Musty air when the fan starts, or a filter that has been in far too long
- New noises when the equipment starts up
- Nobody has opened up the system in over a year
- A surprise breakdown during the last hot or cold spell
- A newer unit with warranty terms that call for regular professional service
- Longer run times to get to the thermostat setting
- No real sense of how healthy your heating and cooling equipment is
- Higher heating and cooling costs with no clear explanation
Act Before It Gets Worse
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. If you notice any of these signs, call (763) 247-5064 for a prompt inspection.
