Who we are

Your local HVAC team for the Valley and Greater Houston

Texas Heatwave AC and Heating is a family-owned HVAC company built on doing right by our neighbors. Owner Miguel Ajpacaja started the business in 2023 after more than ten years in the trade, and today we run two full service teams — one in Harlingen for the Rio Grande Valley, and one in Houston for the greater metro. Same values, same honest work, on both sides of Texas.

When your air conditioner quits on a 100-degree afternoon, you don't want a runaround. You want someone to show up, tell you plainly what's wrong, and fix it for a fair price. That's how we run every call — for homes and businesses alike.

We're fully licensed and insured, we quote before we start, and we back small repairs with a 100% satisfaction guarantee. From a quick AC repair to a full system replacement, you get the same friendly, straight-talking service every time.

Preventive maintenance

Stop breakdowns before they start

The best AC repair is the one you never need. Two tune-ups a year keep your system clean, catch worn parts before they fail, and hold down your energy bills through the peak of summer and the winter cold snaps.

On every visit, our techs check refrigerant levels, tighten electrical connections, clear the condensate drain, and test the parts that do the heavy lifting — so your AC and heat are ready before you need them.

Meet the Owner

I've spent more than a decade in the HVAC trade, learning the work hands-on, one system at a time. In 2023 I started Texas Heatwave to build the kind of company I'd want working on my own home — honest, fair, and respectful of your time and your money.

My team and I treat every house and business like it's our own. When you call, you get people who care whether the job is done right, not just done fast. Thanks for trusting us to keep your family comfortable.
