Common Causes of Heat Pump Leak

One of the effective ways of heating your house is heat pumps. Unfortunately, there’s a chance for them to experience leaks, even if you’ve got the best unit possible. The job of your heat pump is to warm your house during the cold months and cool your house during the hot months.  

To do its job, a heat pump will move heat out of your house during summer and into your house during the winter. A heat pump can achieve this with the help of a refrigerant. Unfortunately, several factors can cause heat pump leaks.  

Today, we’re going to talk about the most common causes of a heat pump leak.  

Condensate Drain Clog 

To direct moisture out of your house, the condensate drain system depends on several tubes. If these tubes are blocked, it can lead to clogs that prevent the flow of moisture. The water will slowly back up if a clog occurs. If left ignored, it will start to flow out of the drain pan.  

Overflow Pan Crack 

Just like an AC unit, a heat pump will pull out humidity from the air. Then, the humidity will accumulate on the coil and drips down the overflow pan. The pan might start to rust over time. This can result in cracks. If the pan cracks, you’ll end up with a leaking heat pump.  

Dirty Coils 

The cold evaporator coil inside the unit will accumulate condensation from the air. Then, this condensation will flow down into the overflow pan. Unfortunately, the coils can malfunction and cause the water to drip onto your floor if they’re extremely dirty.  

Frozen Evaporator Coils 

During the summer season, low refrigerant levels can result in ice forming on the cooling coils. This will affect the cooling process and the function of your heat pump. It can produce ice on the evaporator coils if the levels of refrigerant in the system are lower than they should be. This affects the ability of the pump to operate properly. When you turn off the system, the ice will melt. The melted ice will drip down the floor, causing your heat pump to leak.  

Drain Issues 

Almost every heat pump has a drain pan. The job of this pan is to gather condensation from the heat pump. The pan can overflow if it becomes clogged with algae, mold, or debris. Next, it will produce a puddle of water around the unit. The water will run over and cause leaks if the condensate pan isn’t properly installed or the drain line gets clogged. On a lot of occasions, the unit will turn off automatically before this happens. However, you will have to address this problem right away. 

How to Avoid Heat Pump Leaks 

The ideal way to avoid heat pump leaks is to address possible issues early on. If you schedule annual inspections of your heat pump, you can easily prevent leaks and other damages from happening. Furthermore, you can improve the efficiency of your heat pump if you regularly conduct proper maintenance of your heat pump.
