How to Prepare Your HVAC System for Holiday Season Guests

Expecting guests this holiday season? Here's how to make sure your HVAC system keeps your home cozy, safe, and stress-free for everyone.

As the holiday season approaches in Southern California, it's time to prepare not only your menus and guest lists but also your home's HVAC system. Whether you're expecting a few friends or a full house of family, a well-functioning heating and cooling system can make all the difference in creating a warm and welcoming environment.

Why Your HVAC System Needs Attention Before the Holidays

During the holidays, your home experiences increased activity, more cooking, and additional body heat all of which can put added strain on your HVAC system. If your system hasn't been serviced recently, this extra demand can reveal hidden issues, from inconsistent temperatures to complete breakdowns. Planning ahead allows you to avoid last-minute emergencies when technicians are busiest.

Check Airflow and Comfort Zones

Make sure warm air is distributed evenly across all rooms, especially if you're using guest bedrooms or expanding to additional areas of the home. Weak airflow could indicate clogged filters, dirty ducts, or blocked vents. Check our guide on how to improve HVAC airflow for tips on balancing comfort across your space.

Clean or Replace Your Air Filters

A clean filter ensures better air quality — which is especially important if guests have allergies, asthma, or are sensitive to indoor pollutants. Replacing the air filter also helps your HVAC system run more efficiently, reducing the chances of overheating or poor performance.

Adjust Your Thermostat Settings

Use your programmable or smart thermostat to optimize comfort before guests arrive. You can set a warmer temperature during active hours and lower it overnight or when no one’s home. Not sure how to set it best? Read our thermostat settings guide for seasonal advice that works year-round.

Schedule a Pre-Holiday Maintenance Check

If it's been a while since your last inspection, fall is the perfect time to schedule an HVAC tune-up. A technician can catch small problems early, clean components, and ensure your system is ready for extra use. This also gives you time to plan for any repairs  or even consider an upgrade if your system is aging.

Don’t Forget About Air Quality

Consider installing a whole-home air purifier or upgrading your filter to a HEPA option to reduce holiday odors, cooking smoke, and allergens. Good indoor air quality keeps everyone more comfortable and helps prevent guests from catching seasonal bugs during their stay.
