Dealing with a frosted heat pump

Winter is not the most accessible season to have your HVAC unit running.

There is always the fear of having the unit frozen when the temperatures drop to deficient levels.

What’s more, this is not a surprising occurrence. What matters is understanding how best to tackle such a situation where your heat pump is frozen to a point where it cannot work. So what should you do when you find yourself in such a dilemma? Well, first, you need to establish the cause of the frosted heat pump. Usually, there are two categories of causes, beginning with minor and major(red flag) causes. These red-flag causes require professional HVAC intervention and include cases of low refrigerant, poor defrost relay, malfunctioning outdoor fan motor, and bad defrost thermostat and control, just to mention a few. Other not-so-serious causes of the frosting may include the outdoor coil being blocked, leading to a snowdrift. It may also be a case of the unit sinking to the ground leaving no room for ice to melt or water to drain. A leaving gutter with dripping water on top may be a contributing factor. In some cases, freezing rain may be behind this issue. Nonetheless, there are a few things you must do to redeem the unit. Remove the ice on top of the unit after switching it off. You should also repair gutters and raise the unit above ground. Always ensure that there are no leaves or ice underneath the unit. The last thing you need is for the heat pump to be blocked since restoring it will cost you money.
