Even in mild Orange County winters, your HVAC system works hard to keep your home or business comfortable. Colder mornings and cooler nights can put extra demand on your heating equipment, making regular maintenance essential to prevent unexpected breakdowns, improve energy efficiency, and extend the lifespan of your system. At 20th Century Air, we believe that a little preparation goes a long way when it comes to protecting your comfort all season long.
1. Replace or Clean Air Filters Regularly
Your HVAC filter plays a crucial role in maintaining airflow and indoor air quality. During winter, when your system runs more frequently, filters can quickly accumulate dust and debris. A clogged filter forces your system to work harder, driving up energy costs and increasing wear on components. Replace disposable filters every 1–3 months or clean reusable ones as recommended by the manufacturer.
2. Schedule a Professional Tune-Up
Routine HVAC maintenance is the most effective way to ensure your system performs at its best. During a winter tune-up, one of our technicians will inspect your system for leaks, test safety controls, clean coils, check refrigerant levels, and verify that all electrical connections are secure. This proactive approach helps detect minor issues before they become costly repairs and ensures that your unit operates efficiently throughout the season.
3. Keep Vents and Registers Clear
Blocked vents can restrict airflow and cause uneven heating throughout your home. Take time to ensure furniture, rugs, and curtains are not obstructing air vents or returns. This simple habit helps your HVAC system maintain consistent temperatures and reduces unnecessary strain on the motor and ductwork.
4. Inspect and Seal Ductwork
Leaky ducts can waste up to 30% of your system’s heating output, leading to higher bills and uneven comfort. Check visible ductwork for holes, gaps, or disconnected joints. Sealing these leaks not only conserves energy but also keeps dust and allergens from circulating through your home.
5. Keep the Outdoor Unit Clean
Even though Southern California rarely sees snow, outdoor debris like leaves and dirt can still accumulate around your condenser. Gently clean around the unit and ensure at least two feet of clearance on all sides for optimal airflow.
6. Upgrade Your Thermostat
A programmable or smart thermostat is a simple way to improve comfort and efficiency. You can schedule temperature changes throughout the day, reducing energy use when you’re away and maintaining the perfect indoor climate when you’re home.
7. Don’t Ignore Warning Signs
If you notice unusual noises, weak airflow, or inconsistent temperatures, don’t wait to call 20th Century Air. Early diagnosis and repair can save you from costly breakdowns and ensure your system keeps running smoothly all winter long.
