Staying Cool This Fall: HVAC Tips for Austin Homes During October Heat

Fall is officially here, but if you live in Austin, TX, you know October doesn’t always bring crisp, cool air. Instead, it’s often a mix of lingering summer heat and unpredictable temperature swings. That makes it tricky to know when to switch from AC to heat, or whether you should keep running your air conditioning well into the season.

The good news? With a little HVAC maintenance and planning, you can keep your Austin home comfortable, energy-efficient, and ready for those cooler nights when they finally arrive. Here are some basic tips to keep your home comfortable during this transition:

1. Schedule Seasonal HVAC Maintenance

Even if your AC has been working hard all summer, October is a smart time to schedule a tune-up. A licensed HVAC technician can:

• Check for worn parts
  
• Clean coils and filters
  
• Test airflow and thermostat accuracy
  
• Ensure your system is ready to switch between cooling and heating

Regular maintenance helps prevent breakdowns when you need your HVAC system the most—and it can extend its lifespan.

2. Change Your Air Filters

Austin’s warm fall weather means your AC is still running, and dirty filters make it work harder than necessary. Swap filters every 30–60 days to improve indoor air quality and keep energy bills lower. This is especially important in October, since ragweed and other allergens are common in Central Texas.

3. Use Ceiling Fans to Stay Comfortable

Ceiling fans don’t cool the air, but they create a breeze that makes your home feel cooler. In October, keep your fans spinning counterclockwise to circulate cool air. Once temperatures finally drop, you can reverse the direction to push warm air down.

4. Seal Drafts and Air Leaks

Even while it’s hot, sealing windows and doors helps keep cool air inside and hot air out. When colder weather arrives, those same seals will keep heat in. Weatherstripping, caulking, and simple insulation upgrades can make a noticeable difference in both comfort and energy bills.

5. Adjust Your Thermostat Settings

Since Austin nights can be cooler in October, consider setting your thermostat a few degrees higher during the day and lowering it slightly in the evening. Smart thermostats make it easy to manage these changes automatically, so you’re not constantly adjusting settings.

6. Plan for Heating Season

Even if you don’t need your heater just yet, October is the right time to test it. Turn on your furnace or heat pump for a short cycle to make sure it’s working properly. Catching issues early means you won’t be stuck waiting for repairs on the first chilly night.
