The Short Answer
Twice a year. Schedule a heating tune-up in the fall and an AC check in the spring. This keeps both systems running efficiently when you need them most.
Why Twice a Year Matters
Think of HVAC maintenance like an oil change for your car. Skip it, and things still work — for a while. But over time, small problems compound into expensive failures.
Regular maintenance:
- Helps prevent breakdowns — Most emergency calls we get could have been avoided with a tune-up
- Extends equipment life by 5-10 years
- Reduces energy bills by 10-25%
- Maintains your warranty — Most manufacturers require annual maintenance
What Happens During a Tune-Up?
A professional HVAC tune-up includes:
Heating (Fall)
- Inspect and clean the burner assembly
- Check the heat exchanger for cracks
- Test safety controls and gas pressure
- Inspect the flue and ventilation
- Replace the air filter
- Check thermostat calibration
Cooling (Spring)
- Clean the condenser coils
- Check refrigerant levels
- Inspect electrical connections
- Test the compressor
- Clean the condensate drain
- Replace the air filter
What You Can Do Between Visits
Between professional tune-ups, there are a few things you can do:
- Change your air filter every 1-3 months — This is the single most impactful thing you can do
- Keep vents and registers clear — Don't block them with furniture or curtains
- Keep the outdoor unit clear — Remove debris, leaves, and snow from around your AC unit
- Listen for unusual sounds — Early detection prevents expensive repairs
