The Complete Guide to
HVAC in Texas
Texas isn't just hot — it's the most demanding climate for residential air conditioning in the continental United States. This comprehensive guide helps you navigate equipment decisions, energy costs, and maintenance with Texas-specific data.
Why Texas HVAC Is Different
Three factors combine to make Texas the toughest environment for residential cooling: extended operating season, extreme temperatures, and challenging humidity.

The result: Texas AC systems experience 25-33% shorter lifespans than national averages. A 10-year-old DFW system has accumulated wear equivalent to a 13-15-year-old system in moderate climates. Equipment sized for moderate climates fails here. Maintenance schedules designed for four-month cooling seasons fall short. And homeowners face $5,000-$20,000 decisions with limited access to transparent information.
