HVAC service for one of Texas' fastest-growing cities

Leander has grown fast, and most of its homes were built in the last 20 years. That means a lot of Leander homeowners are living with the system the builder picked: often the smallest, most basic unit that met code. As those systems come off warranty, many owners start seeing their first repairs, rising electric bills and upstairs rooms that won't cool.

Kassa Kool is based in Northwest Austin, about 20 minutes from most Leander neighborhoods.

Hot upstairs? You're not alone in Leander

In many Leander two-story homes, one system serves both floors. Cool air sinks, heat rises, and the upstairs runs 5 to 8 degrees warmer on summer afternoons. A bigger AC rarely fixes it. These usually do:

  • Balancing dampers to send more air upstairs in summer
  • An added or larger upstairs return so hot air has a way back to the system
  • Sealing and insulating long attic duct runs that lose cooling before the air arrives
  • A zoning system that cools each floor on its own thermostat
  • A ductless mini-split for a single bonus room or media room

We measure airflow room by room first, then recommend the simplest fix that works.

When your builder system comes off warranty

Most new-home HVAC warranties cover parts for 5 to 10 years, but not labor or maintenance. Before yours runs out, a thorough checkup can catch installation issues like low refrigerant charge, kinked lines or a clogged drain while repairs may still be covered.

If your system is already out of warranty and struggling, we'll tell you honestly whether a repair or an upgrade is the better value, and 0% same-as-cash financing for 25 months is available with approved credit.

Rebates for Leander homeowners

Austin Energy rebates generally don't apply in Leander. Depending on your address, your electricity comes from Pedernales Electric Cooperative (PEC) or is delivered by Oncor. Check the name on your bill, and we'll look up current programs when we quote a new system.

Leander HVAC FAQ

Will you work on a system that's still under builder warranty?

Yes. We can diagnose the problem and tell you whether it's likely a warranty item. Some manufacturer warranties require the original installer or a registered dealer for covered repairs, so check your paperwork first and we'll help you figure it out.

Why is my new Leander home so humid inside?

An oversized system can cool the air quickly and shut off before it removes moisture. Fan settings and leaky ducts also play a part. We can check your system's run time and airflow and recommend a fix, from a fan setting change to a dehumidifier.

How fast can you get to Leander?

Same-day visits are often available if you call in the morning. After-hours appointments are available too.

Do Austin Energy rebates apply in Leander?

Usually not. Most Leander homes are on PEC or Oncor. We'll check current programs for your address when we give you a quote.
