617 AC Installation Contractors in Dallas, TX

Dallas summers are relentless — July and August highs average 96°F with more than 100 days above 90°F every year, and even moderate humidity makes poorly cooled spaces uncomfortable fast. AC installation Dallas is one of the most active home services markets in Texas, with 94 contractors, a 4.7-star average, and 40 companies offering 24/7 scheduling for urgent installs and replacements.

Window units run $150-$700 installed, ductless mini-splits for a single zone cost $2,000-$8,000, and central AC replacement using existing ductwork typically lands between $3,500 and $12,000. High-efficiency systems and larger square footage push costs toward the upper end. Texas licenses HVAC contractors through the Texas Department of Licensing and Regulation (TDLR), requiring a Class A or Class B license with 48 months of practical experience in the prior 72 months — or 36 months with an approved technical certification.
