Spring HVAC Checklist: Get Your AC, Furnace, and Heat Pump Ready for Warmer Days in Los Angeles & Orange County

Prepare your HVAC system for warmer days in LA and OC with this spring checklist—your guide to comfort, efficiency, and peace of mind.

As winter fades and warmer days roll into Los Angeles and Orange County, now is the perfect time to give your HVAC system the attention it needs. Whether you rely on an AC unit, furnace, or heat pump, early spring is your chance to prepare your home for the heat without any surprises—or emergency repair calls.

At Smartchoice Service, we help local homeowners keep their comfort systems running smoothly and efficiently all year round. Here’s a practical, easy-to-follow spring HVAC checklist you can use right now.

Replace or Clean Air Filters

This is the easiest and most overlooked step. Dirty filters restrict airflow, force your system to work harder, and reduce air quality. Swap out your filters or clean reusable ones every 1–3 months depending on use.

Schedule Professional HVAC Maintenance

A spring HVAC tune-up is essential to catch issues before they become problems. A technician will inspect coils, check refrigerant levels, tighten electrical connections, and ensure your system is operating safely and efficiently.

Test Your Thermostat

Before temperatures spike, check your thermostat. Set it to cooling mode and ensure it responds correctly. If you don’t already have a smart thermostat, this is the perfect season to upgrade for better energy savings.

Clear the Outdoor Unit

Remove leaves, dirt, and debris from around your AC condenser or heat pump. Give it at least 2 feet of clearance on all sides for proper airflow.

Check Ductwork and Vents

Look for visible signs of wear, leaks, or disconnection in your ductwork. Also, make sure all vents in your home are open and unblocked for balanced airflow.

Listen for Unusual Noises

If you hear rattling, buzzing, or grinding, call a professional right away. Unusual noises often signal that something is loose, worn out, or on the verge of failing.

Consider Upgrading Outdated Equipment

If your AC or furnace is over 10–15 years old, it might be time to invest in a new, energy-efficient installation. Today’s systems use less energy and cool more evenly, especially in California’s climate.

Don’t Forget Your Furnace

Yes, it’s spring—but ignoring your furnace until next winter isn’t a great idea. Now’s a good time to schedule a post-season check to make sure it’s in good shape and ready for next year.
