Many homeowners in Wind Gap, PA, prefer heat pumps because they keep your home comfortable year-round; they can warm your home when it’s cold and cool it down when it gets too hot. However, sometimes, you may notice your heat pump blowing hot air when in cooling mode, making it unable to cool your home. Here are some reasons for a heat pump heating while in cooling mode.
Wrong Thermostat Setting
If your thermostat setting is incorrect, it will blow hot air around your home. When you notice your heat pump is blowing hot air, check if your thermostat setting is in cooling mode and adjust it accordingly.
Apart from wrong settings, other thermostat problems, such as faulty circuit breakers, low batteries or damaged thermostats, can cause a heat pump to remain stuck in heating mode. So, it’s good to have an HVAC professional check your system when you notice a problem.
Damaged Reversing Valve
Heat pumps switch between cooling and heating modes by reversing refrigerant flow, which becomes possible when through the use of a reversing valve. Sometimes, the valve may get stuck, causing the system to remain in heating mode even after you switch the thermostat to cooling mode. The valve can stick when it’s faulty or when the switching mechanism has a problem.
Low Refrigerant Levels
Heat pumps don’t generate heat like furnaces; they move heat in and out of your home using refrigerant. Without enough refrigerant, a heat pump won’t be able to absorb enough heat from your room and move it outside, which causes it to blow hot air in cooling mode.
Because a heat pump doesn’t consume refrigerant during normal operation, any drop in level is usually due to leaks in the system. A qualified air conditioning maintenance professional can identify and repair leaks in the refrigerant line and add new refrigerant.
