Seasonal HVAC Maintenance Checklist for Texas Homeowners

If you’ve lived in Texas long enough, we know you know our seasons are… fickle. One minute it’s 102° with the sun roasting you like brisket, and the next you’re dusting off that one (and only) jacket you own. Probably.

So, whether you’re reading this in the blazing furnace of July, the frosty clutch of January, or that random week in March where Texas throws a full-blown FIT, this checklist has you covered. Scroll accordingly, folks.

Pro tip: Bookmark this one so when you find it again in a year, you’ll have the comforting realization that HVAC jokes age better than your air filter.

Fall/Winter HVAC Prep

Texas winters may not be the tundra, but when that first cold snap sneaks in, you’ll be glad you planned ahead...

Swap your filters: Think of this as your system’s skincare routine. Fresh filters mean fewer flare-ups of dust-zits. Gross? Yes. Memorable enough to haunt you until you actually change it? Also yes.

Check your thermostat: Flip it to heat and make sure it stays that way. Easy peasy.

Schedule a tune-up: Even in Texas. Your heater hasn’t been touched since last Halloween. It’s basically feral.

Seal up drafts: Your warm air shouldn’t slip out faster than my overweight Frenchie the second my gate cracks open.

Spring/Summer HVAC Prep

Ah yes, Texas’ faaavorite season: Summer Until Further Notice. Here’s how to keep your cool...

Clean around your outdoor unit: Weeds, leaves, and rogue pool noodles aren’t décor; they’re sabotage.

Check your refrigerant levels: Lukewarm AC in August is basically a human rights violation. Mkay?

Test your thermostat (again): Switch it to cool and make sure it actually cools. If not, call us. Simple.

Get that spring tune-up: It’s cheaper than your AC flatlining in July and you calling us at midnight having a total existential crisis. We say that because you wouldn’t be the first. Aaaaand you won’t be the last.

Your Year-Round Checklist

Change your filters every 1–3 months: If you can binge-watch 14 seasons of a show you don’t even like, you can handle this.

Keep vents clear: Furniture blocking airflow? Just move it. Don’t overthink it.

Listen for weird noises: If your system sounds like a dying giraffe, probably time to give us a call.

Final Word

Whether you’re reading this while sipping LAVA-HOT hot cocoa (you maniac) or peeling yourself off leather car seats, staying on top of HVAC maintenance is the best way to keep your home comfortable year-round.
