343 Commercial HVAC Contractors in Dallas, TX

Dallas commercial properties face some of the most demanding HVAC conditions in the country — sustained summer heat above 96°F for weeks at a time stresses rooftop units and drives high energy loads. Commercial HVAC Dallas serves a wide range of business sizes, from small retail to mid-size office, with 44 contractors in the market averaging 4.7 stars and 23 offering 24/7 response for equipment failures that can shut down operations.

Annual maintenance per rooftop unit runs $500-$2,000, service contracts for small businesses under 5,000 square feet cost $1,000-$5,000 per year, and mid-size commercial contracts covering 5,000-25,000 square feet typically run $3,500-$10,000 annually. Texas holds commercial HVAC contractors to the same TDLR Class A or Class B licensing standard as residential work — 48 months field experience in the prior 72 months is the baseline requirement.

Reviews from Dallas commercial clients consistently highlight individual technicians. At Astar Air Conditioning, Jason O. and Stephen Yates are each named for honest, no-pressure service — Stephen specifically for explaining everything without upselling, Jason for following up by email with service summaries.
