AC Replacement & Installation in Houston: what's different
AC Replacement & Installation in Houston is shaped by local conditions. Humidity and mold: Oversized systems and leaky attic ducts leave homes clammy and promote mold on registers and in air handlers.
Slab-on-grade homes with attic ductwork are typical, and many two-story homes run two systems. Older homes inside the 610 Loop may have pier-and-beam foundations with ducts under the floor. Aging R-22 equipment is still common in 1980s and 1990s neighborhoods. For AC Replacement & Installation, that means the contractor should start with load calculation and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: clogged condensate drains. Houston air conditioners pull a lot of water from the air, so algae-clogged drains and tripped float switches are frequent calls.
Inside city limits, mechanical permits come from the City of Houston; suburbs like Pasadena, Sugar Land and Pearland run their own permit offices. The best time to schedule AC maintenance is February through April, before the first stretch of 90°F humid days. Replacement work booked in fall or winter usually means shorter waits than in July.
Houston climate
Summers are long, hot and muggy, with high dew points from May through October. Winters are short and mild, though occasional hard freezes stress heat pumps. Hurricanes and tropical storms bring flooding and power outages.

What size AC do I need?+
It depends on the house, not just square footage. A Manual J calculation accounts for windows, insulation, shading, orientation and your local climate. Oversized systems short-cycle and leave the house clammy.
