Why Is My Heat Pump Running Constantly in Sumter, SC?

A single-stage heat pump that constantly runs is an indication of a problem. Here are four reasons your heat pump in Sumter, SC runs without stopping.

Low Refrigerant Charge

Heat pumps use a refrigerant to absorb heat from your home and transfer it outdoors or from the outdoor space to your home. If the refrigerant leaks, the heat pump works harder to attain the thermostat temperature setting. This can result in the pump running constantly.

Heat Pump Stuck in AC Mode

Heat pumps can warm or cool spaces. They do this by reversing the flow of the refrigerant. If a heat pump’s solenoid valve breaks down, the heat pump might run on AC mode constantly.

When that happens, the heat pump constantly runs without reaching the preset temperature. Call a technician for repairs to get the heat pump running efficiently again.

Undersized Heat Pump

An oversized heat pump cycles on and off as it reaches the desired temperature fast. This makes the system less energy-efficient. On the other hand, an undersized system works harder to reach the thermostat temperature.

These systems take longer to heat or cool a home and thus tend to run consistently. You can ensure this does not happen by contracting a professional to size and install a heat pump.

Failure of the Outdoor Unit

If the outdoor unit fails, the heat pump is not able to absorb or transfer heat between the indoor and outdoor space. When that happens, the indoor unit runs constantly but does not offer any heating or cooling results. The outdoor unit might have problems, such as bad capacitors, broken fans, or compressor burnout among other problems that hinder the flow of the refrigerant.

You can avoid most of the problems above through routine maintenance as recommended by the manufacturer. Call Air Solutions Heating and Cooling technicians in Sumter, SC, for HVAC, geothermal, indoor air quality and heat pump services.
