Texas AirZone

Texas AirZone designs, installs, repairs and maintains heating and cooling systems, ductwork, plumbing, water purification and water heating, indoor air quality, and insulation for homes across Dallas–Fort Worth. In business since 1997, the company treats the whole house as one system, looking at ducts, insulation, airflow, humidity and filtration together. It reports more than 12,000 residential systems and 2,000 commercial installations, and much of its work is on custom and estate homes.

A visit starts with a walkthrough by a comfort specialist, followed by a written proposal when design work is needed. Service is by appointment only, and emergency calls are handled outside regular hours. The same crews that install a system return to maintain and repair it. Work centers on the Park Cities, Plano, Frisco and other North Dallas neighborhoods, with select properties farther out taken by referral. Financing is available for qualifying new systems and major projects.
