Local factors in Houston, TX
Houston's long, humid cooling season keeps air conditioning under heavy load for most of the year, and equipment sizing usually leans toward humidity control as much as raw tonnage. Gulf hurricane exposure and intense rain events put wind rating and drainage details higher on the checklist here than in most inland markets. Much of the metro is slab-on-grade construction from the 1970s onward, with attic-mounted equipment common. Permitting is generally straightforward, but flood-zone elevation rules apply in large parts of the metro.
Houston, TX's mid-tier market tracks close to the national midpoint, which means the spread inside the range above comes more from the local conditions described here than from baseline labor rates.
