Is your heat pump running nonstop? If so, you could be looking at a higher energy bill than what you’re used to. Read on to see some of the most common reasons for a heat pump that just won’t shut off.
Thermostat set to Emergency Heat
Thermostats can be confusing- especially when it comes to heat pumps. Your thermostat has two heat settings: “Heat” and “Emergency Heat”. So, which one should you be using this winter in Asheville? Keep it simple and stick with the Heat setting. Heat pumps pull heat from outside to warm the home. When temperatures are freezing, however, the heat pump must use supplemental heat, usually from an electrical source. This electrical heat is less efficient and more costly, but it doesn’t stay on forever. That is, unless you’re using Emergency Heat. Emergency Heat is meant for- you guessed it- emergencies, such as when the unit won’t turn on. This setting will use electrical heat nonstop until it’s switched. Make sure your thermostat is set to Heat this winter.
Heat pump refrigerant leak in Asheville
Heat pumps use refrigerant to transfer heat into the home. If your refrigerant charge is low, the heat pump will have to work harder to bring in heat, causing it to run continuously. However, low refrigerant is also a problem of its own. Heat pumps don’t use refrigerant like furnaces use fuel, so if your refrigerant is low, it’s leaking. Call Sheer Comfort Heating & Air Conditioning if you have a refrigerant leak in your home.
Dirty air filter
A dirty or clogged air filter can restrict air flow through your HVAC system. This can have countless negative effects on your heating system, including a heat pump that won’t stop running. Low airflow can cause the outdoor heat pump unit to ice over, which will make it run nonstop as it tries to draw heat into the home. When in doubt, follow the golden rule of HVAC: Change your air filter at least once a month!
