Your Katy HVAC team

Local AC & heating for Katy's growing neighborhoods

Texas Heatwave serves Katy from our Houston location, just east down the Katy Freeway (I-10). Owner Miguel Ajpacaja started the family-owned company in 2023 after more than ten years in the trade, and our crew handles it all — from a quick AC repair in a Cinco Ranch home to a full system replacement near LaCenterra or the Katy Mills area, for homes and businesses across the Harris, Fort Bend, and Waller County lines that run through town.

Katy has grown up fast around the I-10 and Grand Parkway (TX-99) corridors, and it sits in one of the hottest, most humid pockets of the Gulf Coast. Between the long cooling season and all the new construction going up across Katy ISD, there's no shortage of hardworking equipment out here — and a system that runs almost year-round shows wear quickly, whether it's in a brand-new build or an older home closer to Old Katy.

We're fully licensed and insured, we quote before we start, and we back small repairs with a 100% satisfaction guarantee. Straight talk and a fair price, every visit.

Katy HVAC FAQs

Straight answers to the questions we hear most from Katy and west Houston homeowners and businesses.

Do you offer AC repair in Katy?
Yes. Texas Heatwave serves Katy and the west Houston area from our Houston location, just east on the Katy Freeway (I-10). We repair, install, and maintain AC and heating systems for both homes and businesses. Call (832) 479-2737 for a free quote.
How fast can you get to my home in Katy?
Our Houston location is right nearby in west Houston, so Katy is one of our quicker runs and we do our best to get there the same day. AC problems don't wait for a good time, so call early in the day for the best shot at a same-day visit.
Do you serve all of Katy, including Cinco Ranch and the newer master-planned communities?
Yes — all across Katy, from Cinco Ranch and the neighborhoods around LaCenterra and the Grand Parkway (TX-99) to Old Katy and the areas near Katy Mills. We handle everything from a single-home AC repair to light commercial systems for local businesses, across the Harris, Fort Bend, and Waller County parts of town.
Why does my AC run so hard through a Katy summer?
Katy sits in one of the hottest, most humid parts of the Gulf Coast, where the cooling season is long and your system works overtime for much of the year. A unit that rarely gets a rest wears out faster — in a brand-new build or an older home alike — which is why regular maintenance and quick repairs really pay off here.
Are you licensed and insured?
Yes. Texas Heatwave is fully licensed and insured and certified by the state of Texas (TDLR TACLA 132429E). You're covered every time our team is on the job in Katy.
