If you’ve lived in Austin for a while, you know the weather keeps us on our toes. One week it’s chilly enough to turn on the heat, and the next you’re running the AC again. On top of that, spring allergies and summer triple-digit days can push your system to its limits.

The good news? A little seasonal HVAC maintenance goes a long way. This HVAC maintenance checklist is designed for central Texas homeowners to help you stay comfortable year-round, keep energy bills manageable, and avoid those last-minute breakdowns.

Spring: Get Ahead of Allergy Season

Springtime means bluebonnets in bloom, but it also brings cedar, oak, and plenty of pollen. Your HVAC system can help keep the worst of it outside — if it’s ready.

What to do this spring:

  • Change your air filter: During the heavy allergy season, swap it out monthly. A filter with a MERV rating of 8–13 is best for catching fine particles.
  • Book an AC tune-up: Getting ahead of the first 90-degree day saves stress later. Regular seasonal HVAC maintenance can improve HVAC energy efficiency by up to 15% (U.S. Department of Energy).
  • Set your thermostat: Aim for 76–78°F when you’re home. Bump it up a few degrees when you’re out to save energy.

Smart energy tip: Upgrading to a smart thermostat can cut cooling costs by about 10–12% each year (ENERGY STAR).

Summer: Beat the Texas Heat

There is hot, and then there’s Austin hot. If there was ever a time when your HVAC has to be on point, it’s during the Texas summer! With average highs in the mid-90s and plenty of 100°+ days, your AC needs all the help it can get.

Summer checklist:

  • Clear the airflow: Dust vents, vacuum registers, and make sure furniture isn’t blocking them.
  • Protect the outdoor unit: A little shade (without blocking airflow) helps it run more efficiently.
  • Adjust your thermostat: Set it around 78°F when home, and closer to 82–85°F when you’re away. Each degree above 72°F can save about 3% on cooling costs.

Smart energy tip: Ceiling fans don’t actually cool the air, but they can make it feel 4–6 degrees cooler. That means you can raise the thermostat without sacrificing comfort and enjoy extra energy savings.

Fall: Stay Flexible

Fall in Austin is a toss-up. Some years, you’ll run your AC in October. Others, you’ll need heat by November. This in-between season is the perfect time to prepare for both.

Fall checklist:

  • Change your filter (again): After a long summer of heavy AC use, it’s ready for a fresh start.
  • Check your heating system: A fall furnace or heat pump tune-up makes sure you’re not caught off guard during the first cold snap.
  • Seal the leaks: Caulking and weatherstripping can cut heating and cooling costs by up to 20% (ENERGY STAR).

Smart energy tip: When the weather is nice, open windows in the evening and let fresh air in — but only if outdoor air quality allows.

Winter May be Mild, But Don’t Skip It

Austin winters aren’t harsh, but sudden freezes happen, as we know, and that’s when HVAC systems tend to fail. A little attention in winter goes a long way.

Winter checklist:

  • Check thermostat settings: Keep it around 68–70°F when home. Lower it slightly while you sleep or when you’re out.
  • Flip your ceiling fans: Switch them clockwise at low speed to gently push warm air down.
  • Test carbon monoxide detectors: Especially if you use gas heat, this step is critical for safety.

Smart energy tip: Lowering your thermostat by 7–10°F for 8 hours a day can save about 10% on heating costs each year (U.S. Department of Energy).

Habits That Work Year-Round

Some things never change — and they’ll keep your system in better shape all year long.

  • Replace filters regularly (every 1–3 months, monthly during heavy use).
  • Keep your outdoor unit clear of leaves, grass, and debris.
  • Schedule professional seasonal HVAC maintenance twice a year: once in spring for cooling, once in fall for heating.
