Commercial HVAC is one of the largest cost components of any Texas commercial buildout or renovation. Getting it wrong — wrong system size, wrong contractor, or wrong spec — can cost you tens of thousands in callbacks and repairs. Here's what you need to know.
Commercial HVAC Cost Ranges in Texas
Retail and office spaces (rooftop package units): $15–$25 per sq ft installed. Restaurant and kitchen environments (with makeup air and hood systems): $25–$45 per sq ft. Warehouse and industrial spaces (large tonnage units): $8–$18 per sq ft. Medical offices (with specialized ventilation requirements): $20–$40 per sq ft.
For a typical 3,000 sq ft office buildout in DFW, expect $45,000–$75,000 for a complete commercial HVAC system installed.
What Drives Commercial HVAC Costs Up
The biggest cost variables are system type, tonnage requirements, ductwork complexity, and whether the building has existing infrastructure you can reuse. Restaurant hood systems and makeup air units are particularly expensive — a commercial kitchen exhaust system alone can run $15,000–$40,000.
In Texas's climate, commercial systems are also sized for significantly higher cooling loads than comparable buildings in northern states. Don't let a contractor undersize your system to win a low bid — you'll pay for it in energy costs and comfort complaints.
Texas Licensing Requirements for Commercial HVAC
All commercial HVAC work in Texas requires a TDLR-licensed Air Conditioning and Refrigeration Contractor. This is state law — not optional. Always verify the TDLR license number before signing a contract. You can check at tdlr.texas.gov.
Every commercial HVAC contractor on BidBridge Texas is verified for active TDLR licensure before they can receive a single project lead.
