Heat pumps are much like air conditioners in that they need refrigerant to cool your home. While this refrigerant should never naturally deplete, leaks and other issues can leave the system needing more. Here are a few signs your Birmingham, AL heat pump may not have enough refrigerant.

Decreased Output

During the warmer months, your heat pump will use its refrigerant to pull heat from inside your home and transfer it outside. Without enough refrigerant moving in the system, your system won’t be able to efficiently meet your temperature needs. You may notice your system struggling with decreased airflow or cooling.

Visible Leak

Check around your external unit for any signs of pooling liquid. If you spot moisture when it hasn’t rained recently, it’s likely a refrigerant leak. The chemicals used in HVAC systems are typically toxic and flammable.

Rather than risk contaminating your yard or putting your family at risk, it’s best to call for fast heat pump repairs. Your technician will expertly restore your system’s efficiency and prevent the leak from causing more damage to your property.


A gurgling noise is a clear indication that there’s an issue with your refrigerant line. This often occurs when the line produces air bubbles as the refrigerant leaks out of the system.

Won’t Cycle

Without enough refrigerant in your heat pump, it’s possible it won’t turn on. Modern systems have advanced monitoring functions that keep track of internal issues. When this monitor determines your heat pump doesn’t have enough refrigerant, it will activate a fail-safe to prevent more damage.

A heat pump can begin to leak refrigerant if the line corrodes or the system develops excessive wear and tear from old age. Contact Total Comfort Heating and Air now to ask about our HVAC maintenance options in Birmingham, AL.
