Maintaining your HVAC system is key to keeping your SoCal home comfortable, energy-efficient, and safe. With winter in full swing and temperatures shifting day to day, a properly maintained heating and cooling system ensures your home stays cozy when it’s chilly and efficiently cool when it warms up.

Regular maintenance also helps your system adapt to changing conditions, reduces the likelihood of unexpected breakdowns, and extends its lifespan. These simple habits help your system respond better to changing temperatures and keep your home feeling just right.

1. Change or Clean Filters Regularly

Dirty filters reduce airflow, make your system work harder, and can lower indoor air quality. Keeping filters clean is one of the easiest ways to improve efficiency and comfort.

What to do:

• Check filters every 30 days, especially during heavy use.
• Replace disposable filters according to the manufacturer’s instructions.
• Clean reusable filters with water and mild soap as needed.

Quick tip: If you notice dust buildup on vents even after changing filters, it may indicate a deeper duct issue.

2. Inspect and Clean Vents and Ducts

Blocked or dirty vents cause uneven heating and can strain your system. Regularly inspecting vents and ducts ensures your home stays comfortable and your system doesn’t overwork.

Steps to follow:

• Remove dust and debris from vents and registers.
• Check ducts for visible damage or leaks.
• Make sure furniture or other objects aren’t blocking airflow.

Quick test: place your hand over each vent. If the airflow feels weaker than usual, it may be time to have your ducts inspected by a professional.

3. Check Your Thermostat Settings

Your thermostat controls comfort and energy use. Minor adjustments can have a significant impact on efficiency and costs.

Tips:

• Set heating schedules for cooler mornings and evenings.
• Consider using a programmable thermostat to optimize energy use.
• Test that the thermostat accurately reflects your home’s temperature.

Quick tip: If some rooms stay colder or warmer than expected, it could indicate issues with heat pumps, furnaces, or ductless mini-split systems.

4. Inspect the Outdoor Unit

Even in mild SoCal winters, your outdoor HVAC unit needs attention. Keeping it clear and clean improves performance and energy efficiency.

Steps to maintain:

• Remove leaves, branches, and debris around the unit.
• Ensure at least 2 feet of clearance on all sides.
• Look for visible signs of wear or damage.

Quick tip: Gently sweep around the base and fan area to avoid airflow obstruction, which can affect both air conditioning and heating performance.

5. Monitor for Strange Noises or Odors

Unusual sounds or smells can indicate problems that should be addressed promptly.

What to watch for:

• Grinding, rattling, or squealing noises during operation.
• Burning or unusual odors from vents.
• Any persistent irregularities in system operation.

Even minor sounds or odors can signal early problems. Address them promptly to avoid bigger issues.

6. Schedule Professional Maintenance

Even with regular at-home checks, a professional inspection ensures your system is running efficiently and safely. Technicians can spot small problems before they become bigger headaches.

Professional services include:

• Inspecting electrical components and connections.
• Testing system performance and refrigerant levels.
• Cleaning coils, fans, and other internal parts.

Consider a seasonal inspection of your HVAC system to stay ahead of efficiency drops and unexpected breakdowns.
