San Antonio’s 2024 Heat Crisis: When Record Temperatures Push HVAC Systems and Emergency Services to the Breaking Point
The summer of 2024 proved to be a defining moment for San Antonio residents as the average maximum temperature last year was 83.7, making it San Antonio’s hottest year since meteorological record-keeping began. This unprecedented heat wave didn’t just break thermometers—it overwhelmed HVAC systems across the Alamo City and strained emergency response networks to their limits, creating a perfect storm of mechanical failures and service demands that left many residents scrambling for relief.
The Scale of San Antonio’s 2024 Heat Emergency
The numbers tell a sobering story. The National Weather Service reported the temperature hit 108 at San Antonio International Airport at 3:20 p.m. The previous highest recorded temperature for the date was 105 last year. What made 2024 particularly challenging was the early onset of extreme temperatures, as we’re already ahead of schedule in 2024, having hit 100 degrees for the first time on May 25—a month ahead of San Antonio’s typical first 100-degree day of the year.
The heat wasn’t just about raw temperature readings. National Weather Service offices in South Texas warned that the feels-like temperatures approached 120 degrees in communities when the actual air temperature was in the lower 100s. High dew points – the measure of the amount of water vapor in the air – caused the feels-like temperatures to skyrocket, creating conditions that pushed air conditioning systems far beyond their design limits.
HVAC Systems Under Siege
When temperatures soar beyond normal operating parameters, HVAC systems face unprecedented stress. Particularly when the weather is hot, a failing HVAC can represent a disaster. The interior of the household can become dangerously warm. The prolonged nature of the 2024 heat wave meant that air conditioning units were running continuously for weeks without respite, leading to accelerated wear on critical components like compressors, capacitors, and cooling coils.
The situation became particularly dire when health systems can be impacted by an influx of patients with heat-related illnesses, while simultaneously dealing with widespread HVAC failures. Those who are most affected by excessive heat are the elderly and young children. The fluctuations of body mass temperature can quickly rise to dangerous levels.
Emergency Response Networks Stretched Thin
The overwhelming demand for emergency ac repair san antonio services during the 2024 heat wave revealed critical gaps in the city’s emergency response infrastructure. Where there is an emergency HVAC San Antonio event, a reliable repair team is needed. The best technicians respond to emergency calls around the clock.
Local HVAC companies found themselves in unprecedented situations, with service calls backing up for days. The combination of equipment failures and parts shortages created a cascading effect that left many residents without cooling for extended periods. The San Antonio Water System has rented four portable HVAC units to help keep its field crews cool amid triple-digit temperatures, highlighting how even municipal services had to adapt to the extreme conditions.

Lessons Learned and Future Preparedness
The 2024 heat wave served as a wake-up call for San Antonio’s emergency preparedness. The City of San Antonio has 52 locations of cooling centers around the region. One way to reduce vulnerability is to reduce exposure to impacts like heat waves with cooling centers. However, the crisis revealed that cooling centers alone aren’t sufficient when residential HVAC systems fail en masse.
Regular inspections may help to prevent problems that result in an emergency failure of the system. This preventive approach becomes even more critical as climate change continues to drive more frequent and intense heat events. In 2023, San Antonio experienced 75 days with temperatures over 100 degrees, and 2024’s patterns suggest this trend will continue.
