Avatex Service Company is a Houston-area HVAC contractor offering air conditioning, heating, heat pump, ductless, indoor air quality, electrical, refrigeration, insulation, and general contracting services for residential and commercial customers. The company services both The Woodlands and Houston markets and offers online estimates, financing, and a maintenance plan.

With a 4.6-star overall rating across 129 reviews, the score reflects a split experience. Positive reviews describe technicians Victor and Jonathan as honest, knowledgeable, and dedicated — going above and beyond on a full system installation and treating customers fairly. One reviewer describes them as "not enough words to describe how dedicated and knowledgeable they are." A Christmas Eve emergency call resulted in full unit replacement by Friday, delivered efficiently and professionally.

The majority of negative reviews — which appear consistently — involve Avatex being dispatched as a warranty contractor through home warranty companies. In these cases, reviewers describe: no-shows without communication, missed appointment windows across multiple dates, technicians not responding to texts or calls, and at least one case where a misdiagnosis (wrong part ordered) was corrected by a different company. Several reviewers note that Old Republic warranty dispatches in particular led to prolonged delays and unresolved issues.

The split between direct customers (who report strong experiences) and warranty-dispatch customers (who report communication failures) is pronounced and worth noting. Homeowners contacting Avatex directly — not through a warranty company — appear to have significantly better outcomes. For Houston and Woodlands homeowners considering Avatex directly for AC repair, installation, or service, the direct-customer record is positive. Warranty company referrals have produced a different pattern.
