HVAC MAINTENANCE GUIDEFOR SUMMERVILLE HOMEOWNERS

Regular maintenance extends your system's life and keeps it running efficiently. Here's what you can do yourself, what needs a professional, and when maintenance stops making financial sense.

DIY MAINTENANCE (DO THIS QUARTERLY)

Change air filter every 1-3 months (more often with pets or allergies)

Clear debris around outdoor unit (maintain 2 feet of clearance)

Check thermostat batteries and settings

Ensure all vents are open and unblocked by furniture

Listen for unusual sounds during operation

Check condensate drain line for clogs (pour 1 cup vinegar monthly)

ANNUAL PROFESSIONAL MAINTENANCE

Schedule professional maintenance twice yearly: once in spring (before cooling season) and once in fall (before heating season). A proper tune-up includes:

Refrigerant level check

Electrical connection tightening

Coil cleaning (indoor + outdoor)

Blower motor inspection

Capacitor testing

Drain line clearing

Thermostat calibration

Safety control verification

WHEN MAINTENANCE ISN'T ENOUGH

If your system is 10+ years old, you're paying to maintain past-prime equipment.

Maintenance can't restore lost efficiency. A 12-year-old system running at 70% capacity will still run at 70% after a tune-up, just slightly more reliably. At some point, the $200-$400/year you spend on maintenance plans would be better invested toward a system that's actually efficient. A new 24+ SEER2 variable-speed heat pump saves $400-$1,200/year in energy costs alone.
