Houston's combination of extreme summer heat — heat indices exceeding 105°F from May through September — and very high humidity makes AC a safety-critical system, not a comfort accessory. The latent heat load (moisture removal) is as demanding as the sensible cooling load. Licensed AC repair contractors in Houston diagnose compressor failures, capacitor problems, refrigerant leaks, and condensate drain clogs. Texas requires HVAC contractors to hold a Class A or Class B license from TDLR — verify at license.tdlr.texas.gov. Repairs run $150–$500; compressor replacement averages $1,400–$2,800. Contractors here serve Houston and the Greater Houston metro including Katy, Sugar Land, The Woodlands, Pearland, Cypress, Spring, and Humble.
