Winter HVAC Maintenance in California

Dirty air conditioner covered in leaves

While California’s winters are mild and typically hover within the 40s to 50s during the day, evenings and mornings can be rather chilly.

Completing the following simple winter maintenance tasks will go a long way toward keeping the chill at bay in the Bay Area:

Check Vents

Ensure all vents are clean, open, and not blocked by furniture or other obstructions. This will facilitate proper airflow throughout your home.

While it may seem counterintuitive from an efficiency standpoint, you should keep vents open in rarely used rooms. Leaving the vents open in these rooms will reduce energy usage and protect your HVAC system from excessive wear and tear.

Replace Air Filters

Homeowners should change their air filters at least every three months or even every one to two months if pets are in the home.

Regularly changing the filter will improve your comfort and indoor air quality. It will also facilitate proper airflow through your HVAC system, reducing wear and tear and extending your system’s serviceable life span.

Clean the Outdoor Unit

If you have an air conditioner or heat pump, removing debris and trimming the foliage from the outdoor unit is imperative. This improves system efficiency, making it easier for your system to maintain the desired thermostat setting.

Listen for Abnormal Sounds

Adjust your thermostat to the heat setting and listen as the unit powers up and commences operation. If you hear squealing, screeching, rattling, or rumbling, you need professional heating service from a certified technician. Consciously listening ensures you won’t ignore any noises.

Install a Smart Thermostat

Smart thermostats are a cost-effective investment that will significantly reduce your utility bills and prolong the serviceable life span of your HVAC systems. They give you superior control over the temperature in your home and make it easy to adjust the thermostat while you are away on vacation, at work, etc.

Seal Drafts

Your ductwork is vital to your HVAC system’s efficiency. Seal leaky ductwork to ensure that all the conditioned air from your HVAC systems makes its way through your ducts and is distributed through your home.

Other areas where heat is commonly lost are underinsulated attics and crawl spaces. If necessary, add or upgrade your insulation to ensure every inch of your home is adequately insulated. You should also use the appropriate caulk or sealant to seal any air leaks around doors and windows.
