Riverside County’s extreme summer heat — with temperatures regularly hitting 100-110°F from June through September — puts enormous demand on residential air conditioning systems. A well-maintained AC handles this demand efficiently; a neglected one breaks down when you need it most. Davis Plumbing and Heating Inc. provides professional AC maintenance throughout Riverside County to keep systems running reliably and efficiently.

What a Professional AC Tune-Up Includes

  • Air filter inspection and replacement — A clogged filter restricts airflow, reduces efficiency by 15-20%, and can cause the evaporator coil to freeze.
  • Evaporator coil inspection and cleaning — Indoor coil accumulates dust and debris over time, reducing heat transfer efficiency.
  • Condenser coil cleaning — The outdoor unit’s coil must transfer heat to the outdoor air effectively. Debris, leaves, cottonwood fluff, and dust all reduce this ability. We clean the condenser fins carefully to restore efficiency.
  • Refrigerant level check — Low refrigerant means reduced cooling capacity and potential compressor damage. We check levels and identify any leak that must be repaired.
  • Electrical connections check — Loose connections cause overheating and system failures. We inspect and tighten all electrical terminals.
  • Capacitor testing — Start and run capacitors are among the most common AC failure points. We test both and replace any that are out of spec before they fail completely.
  • Thermostat calibration — Verify the thermostat reads accurately and the system cycles correctly.
  • Condensate drain cleaning — The condensate drain carries up to 20 gallons per day of water away from the indoor unit. Blockages cause water damage. We flush the drain and treat with algaecide tablets to prevent regrowth.
  • Overall system performance check — Temperature differential, airflow, and system cycling are all verified against manufacturer specifications.

When Should You Get an AC Tune-Up?

Spring (March-May) is ideal — before the summer heat hits and before AC companies get slammed with emergency calls. Getting your tune-up in early spring means: the system is ready for summer, any issues are fixed before they cause breakdowns, and you’re not competing with emergency calls for scheduling priority.

DIY Maintenance Between Professional Service Calls

  • Replace air filter every 1-3 months
  • Keep 2 feet of clearance around the outdoor condenser unit
  • Rinse the outdoor condenser fins with a garden hose annually (low pressure, spraying from inside out)
  • Keep the area around the indoor air handler clean and unobstructed
  • Make sure all supply and return vents are open and unblocked
