Cobos Air Conditioning and Heating | Licensed HVAC Services in San Antonio, TX

Yes, capacitor failure is one of the most common causes of AC breakdowns during our extreme heat. The capacitor helps start your AC's motors, and the strain from constant operation in high temperatures can cause it to fail. If your AC is humming but not cooling, or won't turn on at all, a faulty capacitor is a likely culprit. We offer same-day emergency service to diagnose and replace capacitors quickly, getting your cool air back on.

Regular, professional maintenance is key to preventing capacitor failures. During our seasonal tune-up, we inspect the capacitor for signs of wear, bulging, or leakage. We also clean the coils and check refrigerant levels, which reduces overall strain on the system. Scheduling maintenance in the spring, before the peak summer heat, is the best way to catch a weakening capacitor and other issues before they lead to a complete breakdown.

Absolutely. We understand that an AC failure during a San Antonio summer isn't just an inconvenience; it's a health and safety concern. That's why we provide 24/7 emergency repair services year-round, with a special focus on rapid response during heatwaves. Our technicians are equipped to handle common heat-related failures like capacitor issues, compressor problems, and refrigerant leaks to restore your comfort as quickly as possible.
