HVAC Services Mount Juliet TN | Call Clay Heating & Cooling

A failing capacitor is one of the most common reasons an AC unit won't start, especially during our hot Mount Juliet summers. The capacitor provides the initial jolt of energy to the motors. If it's weak or fails, your system may hum but not start, or it may trip the breaker. Our technicians can quickly test and replace a faulty capacitor to get your cool air flowing again.

Thermostat malfunctions are a frequent issue that can lead to discomfort and high energy bills. First, try replacing the batteries if it's a wireless model. If that doesn't work, the problem could be with the wiring, a blown fuse on the furnace control board, or the thermostat unit itself. Our experts at Clay Heating & Cooling can diagnose the exact cause—whether it needs recalibration, rewiring, or a replacement—to restore precise temperature control in your home.

Watch for warning signs like your AC unit humming but not starting, taking longer than usual to kick on, or randomly shutting off. You might also hear a clicking sound from the outdoor unit or notice that it's not blowing cold air. These are common indicators in our area. We recommend proactive maintenance, as catching a weak capacitor early can prevent a complete system shutdown on the hottest day.
