AC repair, replacement, and maintenance across the Alamo City — keeping you comfortable through 100°F summers and unpredictable winters.
Local conditions create unique hvac challenges for San Antonio homeowners.
San Antonio averages 18–22 days above 100°F annually and over 115 days above 90°F. AC systems run 7–8 months per year here — April through October and sometimes longer — with units operating at maximum capacity just to maintain 78°F indoors when outdoor temps hit 100°F. This extended runtime cuts system lifespan to 10–12 years versus the 15–20 year national average.
Winter Storm Uri (February 2021) brought over 108 consecutive hours below freezing to San Antonio, leaving hundreds of thousands without power and heat for days. Most San Antonio homes rely on heat pumps backed by inefficient electric resistance heaters — systems designed for mild winters that failed catastrophically at single-digit temperatures. Over 25% of Texans resorted to dangerous heating methods like gas ovens.
San Antonio's subtropical humidity averages over 70% in summer, with overnight levels reaching 80–90%. AC systems must work harder to remove moisture from the air, putting extra strain on evaporator coils and condensate drainage systems. High humidity reduces effective cooling capacity and accelerates mold growth in ductwork and air handlers if condensate lines clog or drip pans overflow.
Air conditioning accounts for nearly half of residential electric bills in San Antonio. CPS Energy applies a Peak Capacity Charge from June through September for usage exceeding 600 kWh, and summer bills commonly reach $250–$400 with usage of 1,400 kWh/month. During extreme heat, CPS asks residents to conserve between 2–7 PM, and power fluctuations can damage compressors and capacitors.
As of January 2023, all new AC systems in Texas must meet a minimum SEER2 rating of 14.3 (equivalent to 15 SEER). San Antonio's extreme heat means higher-efficiency systems (SEER 17–20+) pay for themselves faster, but the upfront cost for a new system ranges from $8,000 to $16,000. New federal regulations phasing out R-410A refrigerant may increase costs another 10–30% for units manufactured after January 2025.

Verify the thermostat is set to cool mode and below room temperature. Check the HVAC breaker — CPS Energy grid fluctuations during peak summer demand can trip breakers. Reset once; if it trips again, leave it off and call a technician to avoid electrical damage.
San Antonio's pollen, dust, and humidity can clog filters faster than average. A clogged filter restricts airflow and can freeze your evaporator coil, shutting down the entire system. In San Antonio's 7–8 month cooling season, replace filters every 30–60 days.
Check that the outdoor unit is running and clear of debris. San Antonio storms can deposit leaves, branches, and dirt around condensers, and the city's hard water can leave mineral deposits on coils. Maintain 2 feet of clearance around the unit. If the unit is iced over, turn the system off and call a technician.

(520) 783-3777Close blinds on south- and west-facing windows. Run ceiling fans and avoid using the oven or dryer. When San Antonio hits 100°F+, indoor temps can climb dangerously fast — heat-related illness risk spikes quickly. Move elderly family members, children, and pets to the coolest room.
San Antonio requires permits for HVAC installation and replacement through the Development Services Department. Verify your technician is licensed and registered with the City. During summer heat waves, expect higher pricing and longer wait times — scheduling spring maintenance (March–April) avoids the premium and the rush.

HVAC emergencies in San Antonio follow predictable patterns. Knowing when risk peaks helps you prepare.
San Antonio's HVAC demands are among the most punishing in the country. The city averages over 115 days above 90°F with a cooling season stretching 7–8 months — April through October and sometimes beyond — pushing AC systems to their limits. Air conditioning accounts for nearly half of residential electric bills, and CPS Energy's Peak Capacity Charge from June through September adds further financial pressure. Then Winter Storm Uri proved the other extreme: 108+ hours below freezing, hundreds of thousands without power, and heat pumps that simply could not handle single-digit temperatures. San Antonio's subtropical humidity (70%+ in summer) further strains cooling systems by forcing them to dehumidify as well as cool. If your system is over 10 years old, schedule a pre-summer inspection before the June–August rush when wait times and prices surge.
