AC Maintenance & Tune-Ups
Preventative maintenance is the key to keeping your air conditioning system in top shape. Regular tune-ups can extend the life of your AC, reduce the risk of unexpected breakdowns, and maintain energy efficiency. Our maintenance services often include:
- Cleaning or Replacing Air Filters
A clogged filter restricts airflow, forcing your AC to work harder and raising utility bills. - Checking Refrigerant Levels
Proper refrigerant pressure is essential for efficient operation and reliable cooling. - Inspecting Electrical Connections
We tighten loose connections and check for potential safety hazards. - Lubricating Moving Parts
Keep fan motors and other components functioning smoothly for optimal performance.
Scheduling routine AC tune-ups helps you avoid costly repairs down the line—especially important in the hot Sonoma County summers!
