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 shuts the furnace down on a frigid night. Maintenance is built around this reality for Harrisonburg, VA homeowners: find the problem while it is a trend, and fix it on a calm weekday instead of in an emergency.
The repairs homeowners call us about most are AC Repair and Furnace Repair. If something has stopped working, start there.
Warning Signs for HVAC Maintenance
Spotting the early warning signs lets you act before the problem gets expensive. These are the signals our technicians see most often:
- A newer unit with warranty terms that call for regular professional service
- The system sounds different at startup than it did last season
- Longer run times to get to the thermostat setting
- Higher heating and cooling costs with no clear explanation
- Musty air when the fan starts, or a filter that has been in far too long
- Nobody has opened up the system in over a year
- Uncertainty about whether your system is in good shape or on borrowed time
- A surprise breakdown during the last hot or cold spell
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. If you notice any of these signs, call (540) 646-1514 for a prompt inspection.
