If the heat pump in your Webster, TX home seems to always be running, you might wonder if that’s normal. Constant operation can cause concern. Let’s examine some reasons behind this and find out if there is cause for concern.
Thermostat Settings
First, check your thermostat. See if you set it to “emergency heat.” This setting forces constant operation.
Avoid this mode unless absolutely needed. If you set the fan to “on” instead of “auto,” the fan runs continuously, even if the heat pump isn’t actively heating, which can help even out temperatures but may make you think the entire system is running.
Outdoor Temperature
Heat pumps work best in moderate climates. When temperatures dip below freezing, they will not find the heat outside that is needed and will have to rely on a heat strip or auxiliary heat to provide the warmth that is needed.
Airflow Issues
Restricted airflow hampers performance. Dirty air filters often cause this problem. When air cannot flow freely, your system will continue to run, working longer to reach the set temperature, using more energy.
Check the filters regularly and replace them when dirty. Ensure vents remain unobstructed and keep furniture and curtains away from them.
Refrigerant Leaks
Low refrigerant levels impact efficiency, as a leak means less heat transfer. Your heat pump must run longer to achieve the desired temperature.
You might notice ice buildup on the outdoor unit, another sign of low refrigerant. A technician can find and fix leaks. Don’t attempt this repair yourself because this can be extremely dangerous.
Malfunctioning Components
Older systems or those that receive irregular maintenance often develop problems. A faulty reversing valve might cause continuous operation, because the valve isn’t able to switch between heating and cooling.
A bad capacitor can also prevent proper startup and shutdown. In this case, the system needs professional attention. Seek an expert when you suspect component failures.
Heat pumps should cycle on and off a couple of times each hour. If yours runs nonstop, change your filter and make sure nothing blocks your vents or registers. If you find that simple fixes do not solve the problem, call Davis Air Conditioning & Heating for our professional HVAC services.
