Complete Guide to AC Repair in San Antonio
Most Common AC Repairs in San Antonio
The intense Texas heat puts extreme stress on air conditioning systems. The most common repairs we handle include refrigerant leaks (causing reduced cooling capacity), frozen evaporator coils (often from dirty filters or low refrigerant), failed compressors (the heart of the AC system), faulty capacitors and contactors (preventing the unit from starting), clogged condensate drains (causing water damage), and thermostat failures. Many of these issues can be prevented with annual maintenance, but when they occur, prompt repair prevents further damage and higher costs.
Our Diagnostic Process
Every repair begins with thorough diagnosis. Our technicians check thermostat operation, measure voltage and amperage at the unit, test capacitors and contactors, check refrigerant pressures, inspect electrical connections, examine the evaporator and condenser coils, and verify proper airflow. We use digital manifold gauges, multimeters, and thermal imaging to pinpoint problems accurately. Once diagnosed, we provide upfront pricing before beginning any repairs, so you know exactly what to expect.
Refrigerant Leaks and Recharging
If your AC is blowing warm air or running constantly without cooling effectively, low refrigerant is often the culprit. Refrigerant doesn't "run out"—if it's low, there's a leak somewhere in the system. Simply adding refrigerant without fixing the leak is a temporary fix that will fail again. We use electronic leak detection and UV dye to find even the smallest leaks, repair them properly, evacuate the system to remove moisture and air, and recharge with the correct amount and type of refrigerant (R-410A or R-22 depending on your system age). For more information about refrigerant and system efficiency, visit our AC maintenance page.
Compressor Failures
The compressor is your AC system's most expensive component, and failures are common in aging systems or when electrical issues occur. Signs of compressor failure include the outdoor unit humming but not running, circuit breakers tripping repeatedly, or warm air from vents. Compressor replacement on older systems (10+ years) often isn't cost-effective compared to full system replacement. We provide honest recommendations about repair vs. replacement based on your system's age, condition, and repair costs. If replacement makes sense, we can usually credit your diagnostic fee toward installation. Learn more about new AC installation options if replacement is recommended.
Preventing Future Repairs
Most AC repairs can be prevented with annual maintenance. Our maintenance service includes cleaning coils, checking refrigerant levels, testing electrical components, lubricating motors, inspecting ductwork, and replacing filters. Maintenance customers receive priority scheduling, discounted repairs, and extended warranty coverage. Regular maintenance extends system life from 10-15 years to 20+ years and reduces energy costs by 15-30%. San Antonio's climate demands reliable cooling—don't wait for breakdowns to occur. Explore our preventive maintenance programs to protect your investment.

AC Repair FAQs
How much does AC repair cost in San Antonio?
AC repair costs vary widely based on the problem. Simple repairs like capacitor replacement run $150-300, while major repairs like compressor replacement can cost $1,500-3,000. We provide upfront pricing before beginning work so you can make informed decisions. Many repairs are covered by manufacturer warranties if your system is newer.
How long do AC repairs take?
Most AC repairs are completed in 1-3 hours during the same visit. Complex repairs requiring special parts may take 1-2 days if we need to order components. Our technicians carry common parts on every truck to complete most repairs immediately.
Should I repair or replace my AC?
A good rule of thumb: if the repair cost exceeds 50% of replacement cost and your system is over 10 years old, replacement is often more cost-effective. We provide honest recommendations based on your system's age, condition, efficiency, and repair costs. Sometimes repair makes sense even for older systems if the issue is minor.
Do you offer emergency AC repair?
Yes, we provide 24/7 emergency AC repair throughout San Antonio. Call (210) 501-9445 anytime for immediate assistance. We respond to emergency calls within 2 hours and prioritize families with young children, elderly residents, and those with medical conditions.
What warranty do you offer on repairs?
All repairs include a 90-day labor warranty on our workmanship. Parts warranties vary by manufacturer, typically 1-5 years. If you experience issues with our work within 90 days, we'll return and make it right at no charge.
Why is my AC freezing up in San Antonio?
AC freeze-ups are common in San Antonio and usually result from restricted airflow (dirty filters, blocked vents), low refrigerant levels from leaks, or thermostat issues. The extreme temperature difference between our 100°F+ outdoor temps and desired indoor temps stresses the system. Turn off your AC immediately if frozen and call us for diagnosis.
How often should I change my AC filter in Texas?
In San Antonio, change standard 1-inch filters every 30 days during cooling season (May-October) due to constant AC runtime and dusty conditions. Thicker 4-inch pleated filters can last 90 days. If you have pets or allergies, change filters more frequently. Dirty filters are the leading cause of AC problems in our area.
What is the best AC temperature setting in San Antonio summer?
We recommend 78°F when you're home and 82-85°F when away. Setting your thermostat below 72°F during extreme heat (100°F+) forces your AC to run constantly, causing excessive wear and high bills. A programmable or smart thermostat helps optimize comfort and efficiency for San Antonio's climate.
