If you could look at the readings, you would see most failures coming months ahead. 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. That is the whole point of maintenance for Ann Arbor, MI homeowners: find the problem while it is a trend, and fix it on a calm weekday rather than as a crisis.
The repairs homeowners call us about most are AC Repair and Furnace Repair. Start there if your system isn't running right.
When to Call for HVAC Maintenance in Ann Arbor
Spotting the early warning signs lets you act before the problem gets expensive. Keep an eye out for the following clues:
- It has been more than a year since anyone opened the equipment
- New noises when the equipment starts up
- Recently installed equipment whose manufacturer expects maintenance records
- A filter you cannot recall replacing, or a musty odor at blower startup
- Cooling or heating that takes noticeably longer to reach the setpoint
- Energy bills creeping up without any change in your habits
- No real sense of how healthy your heating and cooling equipment is
- A surprise breakdown during the last hot or cold spell
Early Action Saves Money
