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.
