Emergency AC Repair in Austin
Your AC stopped working during a heat wave. Your family includes young children, elderly relatives, or pets at risk in extreme heat. You're experiencing complete cooling failure at 11 PM on a Saturday night.
We arrive within 1-2 hours across the Austin metro area. Our technicians are available 24/7 including weekends and holidays. Fully equipped trucks carry parts for most emergency repairs, so we restore most systems during the same visit—no waiting days without cooling.
Austin summers routinely exceed 100°F for weeks straight. We responded to over 1,200 emergency calls during the 2023 heat dome. We serve all neighborhoods from Westlake Hills to Pflugerville, and our emergency line is always answered by a real person who can dispatch help immediately.
Air Conditioning Repair in Austin
our AC isn't cooling like it used to. Your system blows warm air or cycles on and off repeatedly. Your unit makes strange noises or produces unusual odors.
We provide complete diagnosis that identifies the root cause, not just symptoms. You get an honest assessment of whether repair or replacement makes more sense for your situation. We complete same-day repairs for most common AC problems, and our work is guaranteed—if it breaks again, we fix it free.
Austin's hard water and dust accelerate AC component wear faster than in other climates. We service all major brands installed in Central Texas homes. Most repairs in Hyde Park and Travis Heights are completed within 3 hours of our arrival.
Central Air Conditioning Repair in Austin
You have a traditional central AC system like most Austin homes. Your split system has an outdoor condenser and indoor air handler. Your whole-house cooling stopped working properly.
Our technicians are trained on all central AC configurations. We test airflow, refrigerant levels, electrical connections, and thermostat operation. We replace failed components the same day in most cases and restore even cooling throughout your entire home.
Central AC systems work overtime during Austin's 4-month summer season. Older neighborhoods like Brentwood often have 15+ year old units needing repair. We carry parts for systems common in Austin homes built from the 1980s through 2020s.
AC Compressor Repair in Austin
Your system won't turn on or cycles off immediately after starting. Your outdoor unit makes grinding, clicking, or buzzing sounds. Your AC runs but doesn't cool despite other components working fine.
We provide accurate diagnosis that prevents unnecessary compressor replacement. We test electrical supply, capacitor, and refrigerant levels first. Repair costs significantly less than full replacement when we catch problems early. New compressor installations include warranty protection.
Austin's sustained high temperatures stress compressors more than in humid climates. Failed compressors are common in systems 10+ years old throughout Round Rock. Hard starts during summer heat waves damage compressor components over time.
Freon Leak Detection in Austin
Your AC blows less cold air than normal despite running constantly. Your system freezes up with ice on outdoor or indoor coils. Refrigerant levels keep dropping and require frequent recharges.
We use electronic leak detectors to pinpoint the exact leak location. UV dye injection makes tiny leaks visible under blacklight. We repair leaks instead of just adding more refrigerant. Proper refrigerant charge restores full cooling capacity.
Austin heat accelerates refrigerant leaks in aging line sets. Many Georgetown homes have copper lines damaged by foundation settling. Leak repairs prevent expensive refrigerant waste and environmental harm.
AC Capacitor Replacement in Austin
Your AC won't start or makes a humming sound but the fan doesn't spin. Your system starts then shuts off after a few seconds. Your outdoor fan blade won't turn without a manual push-start.
This is a quick, affordable repair that usually takes 30-60 minutes. Capacitors fail frequently in Austin heat, so we stock all sizes on our trucks. We prevent motor damage that happens when a failed capacitor forces the motor to work harder. Your system starts reliably and runs efficiently again.
Capacitors fail three times more often during Austin's July-August peak heat. This is the most common repair call we get in Cedar Park during summer months. We carry dual-run and start capacitors for all residential AC sizes.
Blower Motor Repair in Austin
You notice weak airflow from vents throughout your house. Your AC runs but little air comes out. You hear loud squealing, screeching, or grinding from your indoor unit.
We test motor bearings, capacitor, and electrical connections. We clean dust and debris that restrict motor operation. If repair isn't cost-effective, we replace the motor. Strong, consistent airflow returns to all rooms.
Austin dust and cedar pollen clog blower wheels faster than in humid climates. Older homes in Tarrytown often have original motors that need replacement. Variable speed motors in newer systems require specialized diagnosis.
Evaporator Coil Repair in Austin
Your indoor coils freeze with ice buildup. Water leaks from your indoor AC unit. Cooling is reduced despite your outdoor unit running properly.
We inspect coils for leaks, clogs, and corrosion damage. We clean coils to restore heat transfer efficiency. We repair small leaks or recommend coil replacement if damage is extensive. This prevents mold growth and water damage inside your home.
Austin humidity causes coil corrosion in older systems. Many Pflugerville homes have undersized coils from builder-grade installs. Coil leaks often result from improper drain line maintenance.
Ductless AC Repair in Austin
You have mini-split systems in garage apartments or home additions. You use ductless units in older Austin homes without existing ductwork. Your room-by-room cooling systems aren't working properly.
We service all major ductless brands including Mitsubishi, Daikin, LG, and Fujitsu. We repair indoor wall units and outdoor condensers. We fix refrigerant leaks in line sets connecting units. Quiet, efficient cooling returns to individual zones.
Ductless systems are popular in East Austin renovated homes. Garage conversions in Clarksville often use mini-splits. This market is growing as homeowners add cooling to unconditioned spaces.
Air Handler Repair in Austin
Your indoor air distribution unit has blower and coil problems. Your system has variable speed air handlers not modulating properly. Your unit has control board or sensor failures.
We provide complete air handler diagnosis including airflow testing. We repair or replace blower assemblies, coils, and controls. We ensure proper refrigerant flow through your indoor coil. Balanced air distribution returns to all rooms.
Variable speed air handlers are becoming standard in new Austin homes. Older Steiner Ranch homes often have builder-grade air handlers. Austin attic installations expose air handlers to extreme heat stress.
Preventative AC Maintenance in Austin
You want to avoid emergency breakdowns. You're a new homeowner establishing a maintenance schedule. Your system is approaching 7-10 years and needs extra care.
We catch small problems before they become expensive repairs. Regular service extends AC lifespan by 5-7 years. Improved efficiency lowers your energy bills. You get priority scheduling during peak summer season.
Austin AC systems should be serviced twice yearly in spring and fall. Pre-summer maintenance prevents breakdowns during 100+ degree heat. Cedar pollen season requires extra filter and coil attention.
