Your air conditioner works hard — especially during the long, hot summers of the Calaveras and San Joaquin Valley foothills. These six simple steps can help it run more efficiently, last longer, and keep you more comfortable all season long.
1. Change Your Air Filter Regularly
This is the single biggest thing you can do for your HVAC system. A dirty, clogged filter forces your system to work harder, restricts airflow, and can cause the evaporator coil to freeze. For standard 1-inch filters, replace every 1–3 months. Thicker media filters (4–5 inch) can last 6–12 months. Check yours monthly — if it looks gray and dirty, it's time.
2. Keep the Outdoor Unit Clear
Your outdoor condenser unit needs at least 2 feet of clearance on all sides to breathe properly. Trim back plants, remove leaves and debris, and make sure nothing is resting against the unit. A blocked condenser has to work harder and runs hotter — exactly what you don't want in July.
3. Clean the Condenser Coils
Dirt and dust build up on the outdoor coil over time, insulating it and reducing its ability to transfer heat. Gently rinse the coil with a garden hose (spray from the inside out) each spring before cooling season begins. For a deeper clean, a professional tune-up includes coil cleaning as part of the service.
4. Check and Seal Your Ductwork
The U.S. Department of Energy estimates that the average home loses 20–30% of conditioned air through duct leaks. That's a significant amount of money you're literally pumping into your attic or crawlspace. If some rooms are always hotter or colder than others, leaky ducts may be the cause. We can inspect and seal your ductwork during a system check.
5. Use a Programmable or Smart Thermostat
There's no reason to cool an empty house to 72°F. A programmable thermostat lets you set temperatures based on your schedule — cooler when you're home, warmer when you're not. Even raising the setpoint by 7–10°F for 8 hours a day can save up to 10% on your annual cooling costs.
6. Schedule Preventive Maintenance
The best thing you can do for your AC is have it professionally inspected and tuned up each spring. A trained technician will check refrigerant levels, clean the coils, inspect electrical components, test capacitors, verify airflow, and give you an honest written report on your system's condition. Small problems caught in April don't become expensive emergencies in August.
