Katy housing and HVAC
Most homes are slab-on-grade with attic air handlers, and many have two systems. Homes from the late 1990s and early 2000s are reaching replacement age, while newer homes may have spray-foam attics and high-efficiency equipment.
Katy has hot, very humid summers like Houston and mild winters. Heavy rain and tropical storms can flood low areas, as Harvey did in 2017 along the Addicks and Barker reservoirs.
Permits and seasonal timing in Katy
Permits in the Katy area are issued by the City of Katy inside city limits and by Harris, Fort Bend or Waller counties elsewhere. Texas licenses AC contractors through TDLR.
Upstairs cooling
Two-story homes often have upstairs systems that struggle with attic heat, leaving bedrooms warm on summer afternoons.
Condensate drain clogs
High humidity means attic air handlers produce a lot of water, and clogged drains or tripped float switches are common calls.
Aging first systems
Homes from the early 2000s are reaching replacement age, often failing during the first long heat wave of the year.
