Heat pumps are unique because they offer heating and cooling in a single efficient package. But when the heat pump in your Mount Zion, IL, home blows hot air in cooling mode, there’s a problem. Here are a few heat pump issues that might cause your equipment to behave this way.
You’ve Accidentally Engaged Heat Mode
It’s surprisingly easy to switch most thermostats to heat mode accidentally. This can be the result of a stray keypress or an inadvertent bump. If your heat pump blows hot air while it should be in cooling mode, this is the first thing to check.
A Dirty Filter or Coil
Dirty air filters are another likely culprit when a heat pump blows hot air in cooling mode. Restricted airflow limits how much heat your system removes while it runs. Fortunately, a quick air filter change should remedy the problem.
Excess dirt may reach the evaporator coil if your heat pump runs with a dirty filter for too long. Caked-on dirt can prevent effective heat absorption, leaving your air warm. To fix that, you’ll need an HVAC maintenance visit.
Refrigerant Loss
Your heat pump uses refrigerant to produce the chilly air you expect. If it loses enough of this substance via leaks, it will blow hot air even in cooling mode. The only solution is for an HVAC technician to fix the leak and recharge the refrigerant.
Stuck Reversing Valve
A heat pump can fail to switch to cooling mode if its reversing valve gets stuck. In that condition, your system will only produce heat. Installing a new reversing valve is usually the only viable fix.
