AC Repair & Service in Leander

Fast AC Repair in Leander

Same-day appointments are often available in Leander, depending on the day’s schedule. Your technician diagnoses the problem, explains it in plain English and shows you the published price from our StraightForward Pricing™ book before any work begins. The service fee is $131 to get a technician to your door, or $49 for Koala Club members (waived when you have paid work done), and diagnosis is free after that.

AC Services We Provide in Leander

AC Repair

Capacitors, contactors, fan motors, refrigerant leaks, frozen coils and compressor trouble: we repair every major brand, no matter who installed the system. We check the refrigerant charge with superheat and subcool readings, find leaks with an electronic leak detector, and back the work with our written 100% Satisfaction Guarantee.

AC Replacement & Installation

Many Leander homes were built in the last 15 years, so their original builder-grade systems are reaching the age where a major repair raises the replace question. If yours is past saving, we’ll tell you, and you can see every system and tier priced online before anyone comes out. We size every replacement with a Manual J load calculation.

AC Maintenance & Tune-Ups

Most breakdowns we see on a July afternoon start as something a tune-up would have caught: a weak capacitor, a dirty coil or a drain line about to back up. A Cool Check is $149, and Koala Club members get one every spring plus a fall Heat Check. Learn about the Koala Club →

See Your Price Before We Start

Most companies keep their prices hidden until a salesperson is sitting at your kitchen table. We publish ours. Every replacement system and tier is on our website, and every common repair has a set price in the book your technician carries. Leander pays the same published prices as Round Rock, and Koala Club members save 10% on all repairs and replacements.

Common AC Problems in Leander Homes

Leander’s newer neighborhoods and two-story floor plans shape what goes wrong. These are the calls we see most:

• Clogged condensate drain lines. Our most common repair. An attic air handler can overflow into the ceiling when the line backs up. Clearing it is $277, or $249 for Koala Club members.
• Failed capacitors. Texas heat wears them out, and a weak one strains the compressor. We replace capacitors that test outside manufacturer tolerance, and Club members get a lifetime warranty on new ones.
• Hot upstairs rooms. One system serving two floors often can’t keep the second story cool. Airflow fixes, an added return or duct sealing usually come before a second unit.
• Refrigerant leaks at the coil. Common on builder-grade evaporator coils. We find the leak before adding refrigerant, and we weigh in what we use so you pay for the exact amount.
• Warm air from the vents. Often a failed outdoor component, a frozen coil or low refrigerant. Shut the system off and call us before it does more damage.

If you notice any of these, call before the next heat wave turns a small repair into a big one.
