Prevent breakdowns and extend your AC's lifespan with regular maintenance. Constant Appliance Service provides expert air conditioning maintenance and tune-ups throughout San Diego County. Our EPA-certified technicians keep your system running at peak efficiency year after year.

What We Do During an AC Tune-Up

Our maintenance visit is a full system check and service, not a quick filter change. We focus on the items that prevent costly repairs and protect your investment:

• Filter replacement and cleaning — improved airflow and indoor air quality
• Coil cleaning — evaporator and condenser coils for maximum heat transfer
• Refrigerant level check and recharge — when needed, to factory specifications
• Thermostat calibration — accurate temperature control
• Electrical connection inspection — safe, reliable operation
• Condensate drain cleaning — prevents water leaks and overflow
• Blower motor lubrication — quiet, efficient airflow
• Safety controls testing — shutoff and limit switches

Benefits of Annual AC Maintenance

When to Schedule Your Tune-Up

The best time for AC maintenance in San Diego is before the cooling season — typically March through May. That way your system is ready when the heat arrives. We also serve customers who schedule later in the season; we offer same-day and next-day appointments when possible.
