The Ultimate Spring AC Tune-Up Checklist for Triangle Homeowners

Spring in the Triangle means warming temperatures, pollen season, and the perfect time to make sure your AC is ready for another North Carolina summer. A spring tune-up prevents mid-summer breakdowns when every HVAC company is booked solid.

DIY Spring AC Checklist

1. Replace your air filter — A clogged filter restricts airflow and can cause your system to freeze up. Change it every 1-3 months.
2. Clear the outdoor unit — Remove leaves, sticks, and debris within 2 feet. Trim back shrubs.
3. Clean the outdoor unit — Gently hose down the condenser coils. Don't use a pressure washer.
4. Check your thermostat — Switch from "heat" to "cool" and make sure the system responds.
5. Open all vents — Make sure supply and return vents aren't blocked by furniture or curtains.
6. Check the condensate drain — Pour a cup of white vinegar down the PVC drain line to prevent clogs.
7. Listen for unusual sounds — Grinding, squealing, or banging means call a pro.
