Fall is almost here, which means cooler nights that may inspire you to turn on your heating system. But what if you have a heat pump that’s stuck in cooling mode? No worries–there are a couple of ways to deal with this. The leading AC maintenance company in the area, Custom Air Systems, shares some troubleshooting tips here.
But First, A Brief Look at the Heat Pump’s Modes
Heat pumps are an excellent HVAC option because they can both cool and heat your home effectively. While the system is in cooling mode, the refrigerant will circulate through the indoor and outdoor components, absorbing heat from inside your house and expelling it outside. At the same time, it will draw cooler air back into your living space. When the heat pump is in heating mode, the refrigerant flows in the opposite direction, thanks to a component that’s aptly called the reversing valve.
There are a couple of things that can make your heat pump become stuck in cooling mode. Before seeking professional HVAC repairs, you should try a few things. For example:
Check your thermostat. Did you set the heat pump to heating mode, only to find it has returned to cooling mode? The most common explanation for this is that a family member switched it back. This is normal, as everybody has different ideas of what’s a comfortable temperature. Should this be the case, just set the heat pump to heating mode again via the thermostat and wait for the temperature change.
Take a look at the reversing valve. The reversing valve is generally self-automated, but it’s not uncommon for it to become stuck, preventing your heat pump from switching modes. You can take a soft object (like the plastic handle of a screwdriver) and tap either side of the valve body to free it. If this doesn’t work, call an HVAC professional like Custom Air Systems–the reversing valve may be broken, in which case it will need to be replaced.
