Texas Heatwave AC and Heating install and service work in a Brownsville, TX home's mechanical space
Your Brownsville HVAC team

Local AC & heating for the southern tip of Texas

Texas Heatwave serves Brownsville and the rest of Cameron County from our Harlingen shop — about a half-hour north on the US-77/83 expressway. 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 Southmost to a full system replacement out near UTRGV or the Port on TX-48, for homes and businesses alike.

Brownsville sits at the southernmost point of the state, right on the border across from Matamoros — which means one of the longest, hottest cooling seasons in Texas. Add the heavy humidity and salt air rolling in off the Gulf, and an air conditioner down here works nearly year-round. When a system never gets a break, small problems turn into breakdowns fast.

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.

Yes. Texas Heatwave serves Brownsville and the rest of Cameron County from our Harlingen location, just up the US-77/83 expressway. We repair, install, and maintain AC and heating systems for both homes and businesses. Call (956) 591-7829 for a free quote.
How fast can you get to my home in Brownsville?
We're based about a half-hour north in Harlingen, right off US-77/83, so we move fast on Brownsville repair calls and do our best to reach you 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.
Why does my AC run almost constantly in Brownsville summers?
As the southernmost city in Texas, Brownsville has one of the longest cooling seasons in the country, and the thick Gulf humidity makes your system work even harder to keep up. A unit that rarely gets a rest wears out faster, which is why regular maintenance and quick repairs really pay off down here.
Do you service both homes and businesses in Brownsville?
Yes — residential and commercial HVAC across Brownsville, from Southmost and historic downtown to the neighborhoods near UTRGV and out along Paredes Line Road and Boca Chica Boulevard. We handle everything from a single-home AC repair to light commercial systems.
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 Brownsville.
