Proactive Tips to Maintain Your AC System's Optimal Condition
Maintaining your AC system involves more than professional servicing; homeowners can adopt several practices to keep their units in top shape:
- Replace Air Filters Regularly: Swapping out your AC filters every one to three months helps your system breathe easier, boosts airflow, reduces strain on components, and maintains cleaner indoor air quality.
- Keep the Outdoor Unit Clear: Trim plants, sweep away leaves, and keep at least two feet of clearance around your outdoor unit so airflow stays strong, and the system runs without blockages or overheating.
- Monitor Thermostat Settings: Set your thermostat at a steady, efficient temperature—around 76–78°F in summer—to prevent unnecessary cycling, reduce utility costs, and help your system last longer without wear and tear.
- Seal Leaks in Ductwork: Tiny gaps or holes in ductwork let cool air escape before it reaches your rooms, making your system work harder—sealing those leaks can seriously improve overall performance.
- Schedule Professional Inspections: Having your AC inspected by a trained technician each season helps catch minor issues before they turn into expensive repairs and keeps your system reliable when you need it most.
Staying proactive with your AC care not only saves money but also keeps your system running smoothly when it matters most. For added value, don’t miss our latest promotions designed to help Eureka homeowners stay cool and comfortable all season long.

- Refrigerant Level Check and Adjustment: We measure and adjust your refrigerant levels to manufacturer specifications. This ensures your system delivers cool, consistent air without straining the compressor or wasting energy due to under or overcharged lines.
