When you think “winter problem,” you probably picture burst pipes and blizzards—aka, not Houston. Our winters are mild, short, and a little moody. But here’s the twist: winter is when indoor air quality (IAQ) quietly becomes a big deal. We close windows, spend more time inside, kick on the heat—then recirculate the same air day after day. If your home’s air was a playlist, winter is when it gets stuck on repeat.

We hear this one all the time: “It barely gets cold here — do I really need a furnace tune-up?” Short answer: yes. Long answer: absolutely, yes. Even though Houston winters are mild, your furnace still plays a critical role in your comfort and safety. When temperatures drop, you don’t want to discover your furnace is more “decorative” than functional. And beyond comfort, skipping your tune-up can expose you to serious risks.

Fall in Houston is… unpredictable. One day it’s sweater weather, the next you’re wondering why you ever put the shorts away. We get 50° mornings and 85° afternoons, sometimes in the same 24 hours. And while that’s mildly amusing when you’re trying to pick an outfit, it’s not funny when your HVAC system decides it’s not up for the challenge. That’s why fall is the perfect time to give your system some TLC. Here’s your ultimate fall HVAC maintenance checklist — Houston style.

Your HVAC system works hard to keep your home comfortable through Houston’s wild weather — from scorching summers to chilly winter fronts. Without regular maintenance, though, your system can lose efficiency, break down unexpectedly, or shorten its lifespan. Following a seasonal HVAC maintenance checklist helps prevent costly repairs, improve energy efficiency, and keep your system running smoothly year-round.
