How Often Should You Service Your AC?
March 15, 2026
Your air conditioning system is one of the most expensive appliances in your home. A new central AC system costs between $5,000 and $15,000 installed. Yet many homeowners skip the one thing that protects that investment: annual maintenance.

The Short Answer
Once per year, minimum. Ideally, you should have your AC serviced in spring before the cooling season begins. If you have a heat pump that handles both heating and cooling, schedule maintenance twice a year — once in spring and once in fall.
What Happens During a Tune-Up?
- Check refrigerant levels and test for leaks
- Clean or replace the air filter
- Inspect and clean the condenser and evaporator coils
- Test thermostat calibration
- Inspect electrical connections and tighten terminals
- Lubricate moving parts
- Check the condensate drain line
- Measure airflow across the evaporator coil
What Skipping Maintenance Costs You
According to the Department of Energy, a well-maintained AC system operates up to 25% more efficiently than a neglected one. On a $200/month summer electric bill, that's $50/month you're wasting.
Worse, most manufacturer warranties require proof of annual maintenance. Skip it, and your $10,000 system might not be covered when the compressor fails.
