"Our AC went out in the middle of July and CSW had a technician out the same day. They diagnosed the issue quickly, gave us options, and had the new unit installed within 48 hours. Professional from start to finish."

"Had CSW install a new furnace and ductwork in our 1970s ranch home. They also upgraded our thermostat to a Nest. The house has never been more comfortable. Fair pricing and great communication throughout."

"We had CSW install a mini-split system in our converted garage. It was the perfect solution — no ductwork needed. The room stays cool in summer and warm in winter. Very happy with the recommendation and installation."

Common questions about AC repair in San Antonio

AC Repair FAQ

AC repair costs in San Antonio range from $150 to $600 for common repairs like capacitor replacement, contactor replacement, or refrigerant recharge. Compressor replacement costs $1,500 to $3,000. A full AC system replacement (condenser + evaporator coil + installation) costs $4,500 to $12,000 depending on the system size and SEER rating. C.S.W. Power Solutions provides a free diagnostic and written estimate before any repair work begins.
In San Antonio's hot climate, AC systems should be professionally serviced at least twice per year — once in spring before cooling season and once in fall before heating season. Regular maintenance includes cleaning coils, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, and testing thermostat calibration. Annual maintenance extends system life by 5 to 10 years and reduces repair costs by up to 40%.
Common causes include low refrigerant (leak), a dirty or frozen evaporator coil, a failed compressor, a bad capacitor, a clogged air filter, or a malfunctioning thermostat. In San Antonio's extreme heat, AC systems work harder and are more prone to these issues. If changing the air filter and checking the thermostat settings does not resolve the problem, call a licensed HVAC technician for diagnosis.
In San Antonio's climate, a well-maintained central AC system typically lasts 12 to 15 years. Systems that are not regularly maintained may fail in 8 to 10 years. Signs your AC needs replacement include frequent repairs, rising energy bills, uneven cooling, R-22 refrigerant (phased out), and the system is over 12 years old. Newer systems with 16+ SEER ratings can reduce energy costs by 30-50%.
Yes — during business hours. C.S.W. Power Solutions provides same-day urgent AC repair in San Antonio Monday-Friday 7 AM-6 PM and Saturday 8 AM-2 PM. In the Texas summer heat a broken AC is no small thing, especially for children, elderly, and pets. Call 210-504-9796 early in the day for the best chance at same-day dispatch.
For San Antonio's hot climate, we recommend a minimum 16 SEER rating for new AC installations. Higher SEER ratings (18-25) cost more upfront but save significantly on monthly energy bills. A 16 SEER system uses about 25% less energy than an older 10 SEER unit. Federal minimum requirements increased to 15 SEER2 for the South region in 2023. C.S.W. Power Solutions helps you calculate the best SEER rating for your home size and budget.
