Very reasonable and completely professional.Posted on Kevin HouleTrustindex verifies that the original source of the review is Google. Tommy was the technician that they sent out! He was very thorough and very professional. He found the issue right away but didn’t stop there! He continued to perform a multi point inspection and gave me the rundown of what he found!! Great service and great professionalism will def recommend to family and friends!Posted on R. Scott KellTrustindex verifies that the original source of the review is Google. Did repair my AC but destroyed my attic ladder and refuse to make it right. Manager didn’t want to discuss it, just wanted to denigrate and talk over me, complete lack of professionalism. When a repairman is in your home, it’s like a store, “you break it, you buy it.Posted on Cathy JumperTrustindex verifies that the original source of the review is Google. Work was completed satisfactorily, and installers were very professional and personable.

A: In 2026, a single-zone installation in Houston typically ranges from $3,500 to $6,000. Costs vary based on the unit’s SEER2 rating and the distance to the outdoor compressor. We offer 0% APR financing to make this upgrade affordable.
A: For specific rooms or additions, yes. They are more efficient because they eliminate “duct loss” (air leaking into the hot attic). For a whole 3,000 sq ft home, a central AC Installation is usually better, but mini splits are the best “supplemental” cooling.
A: Yes! Most systems we install are “Heat Pumps,” providing powerful heating even during Houston’s occasional freezes. If your unit stops heating, check our Furnace Repair or emergency heat pump services.
