AC Repair in Houston, TX — Top-Rated Companies & 2026 Prices

A Houston AC works harder than almost any residential system in the country: 2,500+ runtime hours a year against heat and Gulf humidity. When it fails, you need two things fast — a licensed tech who can actually come today, and a fair price. Here are both.

Frequently asked questions

How much does AC repair cost in Houston?

Most Houston homeowners pay $150–$650 for a standard repair, plus a $75–$150 diagnostic fee that is commonly waived if you approve the work. Compressors and coils run $900–$2,800. Houston prices track the Texas average — see the table above for 2026 numbers by repair type.

Can I get same-day AC repair in Houston?

Yes — most companies on this page offer same-day windows during the cooling season, and several dispatch 24/7. Call before noon for the best chance of a same-afternoon slot in July and August.

Why does my AC keep freezing up in Houston?

Usually restricted airflow (dirty filter, blocked returns) or low refrigerant. Houston’s humidity makes the ice worse and the melt messier — shut the unit off, let it thaw, and book a diagnostic. Running it frozen risks the compressor.

My AC runs constantly but the house stays humid. Why?

Often an oversized unit that cools too fast to dehumidify, or leaky ducts pulling humid attic air into the system — both extremely common in Houston. A load calculation and duct inspection will identify which one you have.

When is the cheapest time for AC work in Houston?

October through March. Off-season you will find shorter waits, promotion pricing, and no emergency premiums. If your system limped through this summer, that is your window.
