Texas seasons

When it’s in the 80s during the day and the 30s at night, you know you’re going through a Texas winter. It’s around this time of year that, after relying on their heaters for a couple of months, people start needing to switch back and forth from heat to AC, which is harder on the system than running one or the other. So now is a good time to be sure you are giving your HVAC some love to make sure it will see you through the surface of the sun, otherwise known as summer in Texas.

Here are some HVAC tips from our experiences in the field:

Mind the Gap

A little gap in your ductwork may not seem like that big of a deal, but think about it this way: when you’re driving in your car, think about how even opening a window a crack has an effect on the temperature in the car. All that air moving rapidly affects the car quickly, even through a small opening. The same is true with your HVAC. Pressurized air moving rapidly through your system will flow quickly through any gaps, reducing the efficiency of your HVAC by making it work harder to cool or heat your space.

These gaps commonly occur over time without proper maintenance. As the season changes, it’s a great time to have your HVAC serviced to check that your system is sealed up tight.

Tin Foil Is Not Just for Aliens

The attic is basically a giant unconditioned space sitting on top of your house. In the summer, you end up having an oven up there, and in the winter, a freezer. Either makes it harder for your HVAC to do its job. Attic insulation helps with this, but then you have that pesky attic hatch that opens up and lets all that unconditioned air right in. This simple tool that Inspector Matt showcases in the video is a great solution for sealing your attic hatch. It’ll make your attic more efficient.

Watch the Drain Lines

We’ve discussed drain lines, or condensate lines, before. A critical part of maintaining your HVAC system is actually just being aware of these lines. If the secondary line is dripping outside your house, you know the primary is clogged and it’s time for some maintenance.

Inspector Sean also brings up a great point in the video: Do you have a drain pan alarm for your attic unit? Anyway, to clean your condensate line, you can use a home mixture of vinegar and water or a product called NuLine. You should do this every 3-6 months to keep your lines from clogging.
