4 Signs of a Heat Pump That’s Low on Refrigerant

A heat pump is a great way to both cool and heat your home with one appliance. Heat pumps use refrigerant to both cool and heat the treated air throughout your Pittsburgh, PA, home. You want to keep your heat pump in good working order, so heed the following four signs that yours is low on refrigerant:


If you notice a leak anywhere around your heat pump, it’s a sign that your refrigerant is going to run out soon. Look for leaks around the base of the unit and near the connection points. Have service technicians fix the leak right away and refill the refrigerant in your system when this problem occurs.


If you notice ice starting to build up on your system, it’s a clear sign that the refrigerant is low. The refrigerant absorbs heat, so the coils will start to develop ice if there isn’t any refrigerant to do that. Some heat pumps will also start to go into defrost mode if there isn’t enough refrigerant.


If you notice that your heat pump is making noises, specifically a gurgling noise, low refrigerant is likely the cause. If it gets too low, air can get into the line and cause this bubbling to start. You can’t efficiently cool or heat your home when this problem happens.

Weak Output

If you feel like your heat pump isn’t heating or cooling your home enough, low refrigerant is the culprit. If there isn’t enough refrigerant to flow through the system, it can’t heat or cool the air enough to impact the temperature in your home. A heating and air conditioning expert in Pittsburgh, PA, can top it off for you.
