About this listing
Bon Air Service CO. INC. is listed in Grand Prairie, TX, in Dallas County, and holds a Texas Department of Licensing and Regulation contractor licence #92183, current to 09/26/2026. Licensing for air conditioning and refrigeration work in Texas falls under Occupations Code Chapter 1302, which requires contractors to hold a licence before carrying out this work. Grand Prairie sits in IECC climate Zone 3A — warm and humid, meaning hot summers with meaningful winter heating days, so systems are sized for both. New split-system air conditioners installed anywhere in Texas must meet a minimum of 14.3 SEER2 under the federal South-region standard — worth knowing when you compare quotes, since a cheaper unit that falls below it cannot lawfully be installed here.
Round-the-clock service: this contractor advertises 24/7 emergency availability on their own website. We have recorded the claim, not verified the hours — confirm someone will actually answer before you rely on it at 2am.
