Why Doesn’t My Heat Pump in Jacksonville, FL, Ever Shut Off?

As a homeowner in Jacksonville, FL, having a heat pump that runs constantly without shutting off, especially in the summer, can be confusing. Understanding why your system runs nonstop, even when the outside temperature drops, can help you maintain indoor comfort. Here are some possible reasons your heat pump doesn’t shut off:

Running in Heating Mode

When you switch your thermostat from heating to cooling mode, it signals the heat pump’s reversing valve to reverse the refrigerant’s flow. Sometimes, your system can get stuck in heating mode, running continuously even when the outside temperature drops. One common reason for this is a faulty solenoid.

Dirty or Clogged Condenser Unit

Since your condenser is an outdoor unit, it’s common for its air filters to clog with materials like leaves, debris, dust and sticks, which can lower their efficiency. When you have clogged air filters, your heat pump will take longer to move the heated air out of your home, causing it to keep running.

Low Refrigerant Levels

A heat pump uses refrigerant to move heat in and out of your home. If the refrigerant falls below the recommended level, the system will run longer to cool your house. Low refrigerant levels can be due to leaks, which require repair by a qualified service technician.

Undersized Heat Pump System

Heat pumps can cause problems if incorrectly sized. A system that’s too small will struggle to cool your home, causing it to run nonstop.

Although the above issues can significantly impact the efficiency of your heat pump, causing it to run nonstop, a qualified service technician can easily resolve them.
