75°F HVAC | Licensed HVAC Services in San Diego, CA

Yes, that's a classic sign of a refrigerant leak, a common issue in our area due to the constant strain on AC systems. Low refrigerant makes your unit work much harder, leading to poor cooling, higher bills, and potential compressor failure. 75°F HVAC uses advanced leak detection to find and seal the leak, then precisely recharge your system to restore efficient, powerful cooling.

Short cycling—where your system turns on and off too frequently—is often caused by an oversized unit, a dirty air filter, or faulty sensors. It's wasteful and wears out components quickly. Our repair service includes a full diagnostic to pinpoint the exact cause, whether it's cleaning coils, replacing a sensor, or recalibrating your thermostat, to restore normal, efficient operation.

Our San Diego-focused maintenance plans are proactive. We check refrigerant levels and coil integrity to catch small leaks early, clean critical components to prevent overheating that leads to short cycles, and ensure all electrical connections and sensors are functioning correctly. This preventative care keeps your system running smoothly, improves efficiency, and helps avoid costly emergency repairs during our hottest months.
