Local heating & cooling, based right here in the Valley

Texas HeatWave A/C and Heating is a family-owned HVAC company serving Harlingen and the surrounding Rio Grande Valley. Owner Miguel Ajpacaja started the business in 2023 after more than ten years in the trade, and our Harlingen team handles everything from a quick AC repair to a full system replacement — for homes and businesses alike.

Down here, an air conditioner isn't a luxury — it's how you get through July. When yours quits, you don't want a runaround. You want someone nearby to show up, tell you plainly what's wrong, and fix it for a fair price. That's how we run every call across Harlingen.

We're fully licensed and insured, we quote before we start, and we back small repairs with a 100% satisfaction guarantee. Same friendly, straight-talking service, every visit.
