Get the Facts Before You Spend
Clear, no-pressure answers to the questions Leander homeowners actually ask — how your system works, common AC and heating problems, heat pumps and ductless mini-splits, repair vs. replace, real Central Texas cost guides, rebates and tax credits, seasonal maintenance, indoor air quality, permits, and how to choose a company you can trust. Built by a team that would rather teach you than sell you, serving Central Texas since 2009.
Start With the Fundamentals
How your AC actually works
One idea unlocks every cooling repair: your system moves heat — it doesn’t make cold. Understand that and you can tell an honest diagnosis from a sales pitch.
How AC moves heat
- Cool, low-pressure refrigerant — soaks up heat from the air in your home.
- Hot, high-pressure refrigerant — dumps that heat into the outdoor air.
Your AC never makes cold — it moves heat outdoors in a sealed loop, over and over. A heat pump runs these same four parts in reverse to warm your home in winter.
