Why Is My Heat Pump Leaking?

Your heat pump cools your home in the summer months and warms your home in the winter months, much like a traditional HVAC system. So, it’s no wonder that your heat pump can experience issues similar to those you might experience with your heating or cooling system!

Heat pumps function by transferring heat either into your home (in winter) or out of your home (in summer) using refrigerant. However, this process can malfunction in a variety of ways that could lead your heat pump to leak.

Read on to learn why your heat pump could be leaking and how to fix it. Or, if you’re ready to schedule heat pump repair in your St. Louis area home, contact Jerry Kelly Heating & Cooling online or call us today.


There are mainly two different issues that can cause your heat pump to leak, each of which has a different solution.

Frozen Evaporator Coils

This is usually the problem when a heat pump is leaking. If your heat pump’s refrigerant levels get lower than they’re meant to, ice can form on the evaporator coils, which impairs your system’s performance as it attempts to cool your home in the summer. However, when your unit kicks off, the ice may melt, causing your heat pump to leak.

If this is the case, then it’s likely that your heat pump has a refrigerant leak, since refrigerant levels typically remain consistent otherwise. It is dangerous for homeowners to recharge their own refrigerant. It’s best to schedule heat pump repair service with an HVAC professional who can safely bring your refrigerant levels back to normal so your heat pump functions properly once again.

Drain Issues

Your heat pump is meant to drain away excess moisture. The water is supposed to collect in the condensate pan, then travel down a drain line to be carried away from your unit. However, if your condensate pan is clogged with debris or mold, it can overflow instead of sending moisture through your drain line, resulting in the heat pump leak that you’re seeing.

While you can check your condensate pan on your own to see if there’s any physical debris causing a clog, checking for mold or algae is a bit more complicated. The easiest way to resolve this issue is to call in a specialist to remove the clog so your heat pump can properly drain again, resolving the leak.
