Managing Frozen Pump Coils

There are plenty of issues that you could encounter with your HVAC unit; it’s almost unheard of for a unit not to encounter an issue in the years that it’ll run for. While there are plenty of problems that you’re sure to encounter, there are some that are more serious than others and require more attention. One of the issues that we see towards the end of winter, where storms lighten up but temperatures really drop, are frozen pump coils. This is one of the more serious issues that we see, so we want to walk you through the process of recognizing this.

The heat pump is going to be what provides the efficient heating that warms up most homes. When your pump coil freezes, it not only puts your heating and cooling unit at risk for damage, but it also increases the cost of energy. These pump coils are prepared to deal with light amounts of frost because of the inevitable chances of it happening. When heat transfers through this coil, your unit’s refrigerant turns into gas and releases as a moisture, which then turns into frost on the exterior of the coil.

However, if by some chance your heat pump stops working, this small amount of frost will turn into ice, and provide an insulation of sorts to the coil. When this happens, the defrost sensor of your unit should recognize it and begin defrosting the build up, getting it back into working condition.

If the defrost is unable to thaw the coil for too long, this ice buildup could cause your unit to stop working. As a result of this, your unit could experience greater damages that snowball from this one piece malfunctioning. If your coil has a build up of ice, we suggest turning your unit off and checking to see if the defrost eliminates the ice. If the ice remains, it’s time to contact a professional.
