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 locks the system out on a frigid night. Maintenance is built around this reality for Marana, AZ 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. That's the place to start if you need a fix today.
Warning Signs for HVAC Maintenance
Recognizing the warning signs early can save you time and money. Watch for these telltale signs:
- Your last professional tune-up was more than twelve months ago
- A surprise breakdown during the last hot or cold spell
- Cooling or heating that takes noticeably longer to reach the setpoint
- Energy bills creeping up without any change in your habits
- Recently installed equipment whose manufacturer expects maintenance records
- Uncertainty about whether your system is in good shape or on borrowed time
- Filters you cannot remember changing, or a musty smell when the blower starts
- A startup sound that has changed since last year
Don't Wait for a Total Failure
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. If you notice any of these signs, call (442) 201-0613 for a prompt inspection.
