Good to know in Houston

Houston homes need a system that fights both heat and humidity, which is why two-stage and variable-speed units are popular here. Many older homes inside the Loop have tight attics and original ducts, and a new system on bad ducts will not cool well. After a hurricane or a flood, also check that the outdoor pad is high enough.

The City of Houston requires a permit and a mechanical inspection for an AC changeout, and the work must be done by a TDLR-licensed contractor. Check that the permit is pulled in your address before the crew starts.
