About 70 licensed contractors serve the area with an average rating near 4.8 across almost 10,000 verified reviews.

The cost of a new central AC system can catch homeowners off guard. A basic 3-ton unit runs between $5,500 and $11,000, while a mid-efficiency 4-ton model costs $7,500 to $14,000. The most efficient 5-ton systems reach $9,500-$16,000. Those price differences reflect equipment specs and installation complexity rather than markup variation. Texas law requires contractors to hold either a Class A or Class B license from the TDLR, so the cheapest estimate rarely covers what is actually required to do the job properly.
