Trinity Piping & Mechanical | Professional HVAC Repair in Lumberton, NC

Yes, that's a classic sign of a failed AC capacitor, which is a very common repair need in our area's heat. The capacitor provides the necessary electrical jolt to start the compressor and fan motors. When it fails, you'll often hear a humming sound without the system turning on. Our technicians at Trinity Piping & Mechanical can test your capacitor on-site and replace it with a quality part to get your cooling restored promptly.

This is frequently caused by a problem with the heat pump's reversing valve, a key component that switches the system between heating and cooling modes. If the valve is stuck, damaged, or has lost electrical charge, your system can get 'locked' in the cooling cycle. Our experts are skilled at diagnosing reversing valve issues. We'll determine if a repair is possible or if a replacement is the most reliable long-term solution for your home's comfort.

First, check your home's breaker panel to ensure the circuit hasn't tripped. If the breaker is fine, it's time to call a professional. Sudden failures, especially during our seasonal extremes, often point to specific electrical components like capacitors or contactors. To prevent further damage, avoid repeatedly trying to restart the system. Call Trinity Piping & Mechanical. As your local HVAC specialists, we offer prompt, same-day service when possible to diagnose the root cause and get your heating or cooling back online.
