HVAC Guides for Austin Homes
Real homeowner questions, answered with first-party knowledge from our service work across Austin, Round Rock, Cedar Park, Georgetown, and Lakeway.
Should I repair or replace my AC in Central Texas?
A simple decision framework with real Central Texas thresholds — repair under $500 on a unit under 10 years old, replace 12+ with major component failure. Everything in between is the judgment zone.
Why is my AC running but not cooling in the Texas summer?
The 6 most common reasons an AC runs but won't cool in a Texas summer — most are diagnosable in 15 minutes and many are fixable same-day for under $300.
What size AC do I need for my Austin home?
Sizing an Austin AC from square footage alone is how most homes end up oversized. Here's how Manual J load calculations actually work and what tonnage range matches your home.
Are heat pumps worth it in Central Texas?
Central Texas winters are perfect for heat pumps — they cool like an AC and heat at 3× the efficiency of electric strips. Here's when the math works, and when a gas furnace is still cheaper.
When does a ductless mini-split make sense in an Austin home?
Mini-splits aren't a replacement for central AC — they're a fix for problem spaces. Additions, garage conversions, ADUs, and that one room the central system can't reach.
Why is my furnace short cycling in Texas?
Short cycling — when your furnace fires up every few minutes instead of running full cycles — wastes gas, wears out components, and signals a fixable problem. Here's how to diagnose it in a Texas home.
How can my HVAC help with cedar fever and Austin allergies?
Cedar fever, oak pollen, pet dander — your HVAC is the most powerful tool in the home for cleaning the air you breathe. Here's how to use it properly in the Austin metro.
Are smart thermostats worth it in Austin?
Smart thermostats save 10–15% on cooling in a typical Austin home, qualify for Austin Energy rebates, and let you pre-cool before peak rates. The trick is configuring them correctly for Texas humidity.
