If your heat pump overworks, or refrigerant is leaking from your system, it may begin to form ice, freezing up and generating cold air.
What is a reversing valve in a heat pump?
Your heat pump has a failing reversing valve. The reversing valve is a vital component in heat pump systems. It is responsible for reversing the flow of refrigerant in your system, which for you means going from “heat” to “cool” and vice versa.
Why is air flow important in a heat pump?
Healthy air flow is vital to a heat pump. If you haven’t had maintenance in a while, an air flow problem may have developed, which can alter the quality of your heat pump system’s heating and cooling power.
How much heat does a furnace blow?
In a furnace, the heat being produced and blowing into your home starts out at upwards of 110 or more degrees, often much higher than that. A heat pump, however, generates a lower but more even 90ish or so.
Does a heat pump have to be a backup?
A heat pump system is more than capable of keeping up with our cold seasons, and in the event that the outside unit actually did fall behind, there’s a backup system in place that essentially operates like a furnace. This kicks on if your heat pump can’t handle things in its usual way.
What is the reversing valve on a heat pump?
Your heat pump has a part built into it called the reversing valve. This valve reverses the flow of refrigerant within your system. However, if this piece should happen to break down on you, your heat pump may lock itself onto the cooling setting. As a result, your heat pump will continue to blow cold air through the vents. If the reversing valve is the problem, it’s best to call a professional. This is a very complex job to fix.
Does a heat pump blow cold air?

What does "HEAT" mean on a heat pump?
The “HEAT” setting will cause your heat pump to operate in heating mode and blow warm air instead, but only if there is a call from the thermostat. Set the thermostat to cool mode, a few degrees below your room’s temperature, so the thermostat calls for cooling.
What to do if there is no airflow in a heat pump?
If there is no airflow, check the air handler. If there is not enough air blowing out of the vents, check your air filter. The air filter needs to be cleaned if dirty or replaced. Heat pumps perform less efficiently from lack of airflow. Clogged components, particularly the coils and the air filter, can restrict airflow.
Why is my heat pump not cooling?
