Air Industries - Freehold's Reliable HVAC Repair

Yes, this is a frequent issue we see in Freehold homes, especially during our humid summers. A sudden loss of cooling is often caused by a failed AC capacitor. The capacitor is like a battery that helps your outdoor unit's compressor and fan motor start and run. High heat and humidity put extra strain on it. Our technicians can quickly test and replace a faulty capacitor to get your cool air flowing again, often with same-day service.

This is a classic sign of a problem with the heat pump's reversing valve, a common issue we repair in Freehold. This valve is responsible for switching the refrigerant flow between heating and cooling modes. If it's stuck, electrically failed, or clogged, your system can't produce heat. Our HVAC experts specialize in diagnosing and servicing reversing valves to restore your system's proper function for year-round comfort.

That humming noise often means the compressor is trying to start but can't, which is a strong indicator of a bad capacitor—a very common repair call for us in Freehold. Do not repeatedly turn the system on and off, as this can damage the compressor. The safest step is to turn the system off at the thermostat and call us. Our technicians can safely test the capacitor and other components to prevent further damage and get your system running smoothly.
