If your heat pump won’t turn off, this can send your utility bills through the roof and may also cause serious damage to the system itself. While many homeowners may complain that their heat pumps don’t turn on, the opposite problem is no less threatening. Here are a few reasons why your heat pump in Plano, TX may constantly remain on.
Dirty Filters
Over time, dirt and debris accumulate on your heat pump’s air filters. If you don’t clean or replace these filters at least every three months, the dirt may actually prevent cool air from entering your home. Under these conditions, your HVAC system may end up operating constantly in a vain attempt to keep you cool.
Refrigerant Leak
Ultimately, a heat pump with too little refrigerant will neither heat nor cool your home effectively, and this may cause your thermostat to force it to work 24/7. Hissing or gurgling noises may further confirm the existence of a refrigerant leak. Refrigerant can be dangerous. If you suspect that you have a large leak inside, leave your home and call a service technician to fix the problem.
Reversing Valve Issues
The reversing valve is the component that enables your heat pump to respond to the needs of the seasons and switch between heating and cooling modes. The valve controls the direction in which refrigerant moves through your system and therefore also controls whether the system will deposit heat indoors or outdoors. If anything happens to force the valve to remain in its heating mode position, your HVAC system will become useless as a cooling device.
If your heat pump is unable to cool your home, this will again only force your thermostat to push it to work even harder. Hence, it may never turn off at all. If this is truly the explanation for that behavior, you’ll probably notice your heat pump heating your home instead of cooling it. Electric backup/auxilliary heaters that are stuck in the energized state can also cause this.
If your heat pump refuses never stops running, it may eventually reach a point where it completely stops working. To prevent that, you must take action. Call our team at Samm’s Heating and Air Conditioning to request HVAC services in Plano, TX today.
