Winter is coming, and you’ll soon be relying on your heat pump to keep your home warm throughout the day. More usage means more stress on the system, which equals a higher chance for various parts of the heat pump to malfunction. If you want to keep your heat pump in the best possible condition, look out for the following signs that your system is in need of some professional service.


Even if the temperature outside is above freezing, ice can still form on the outside portion of the heat pump. This is because the heat pump coil is constantly siphoning thermal energy from the air around it, causing the temperature to drop. A little ice isn’t necessarily a problem, since the system has a defrost cycle designed to melt any build-up off the coil. However, if that defrost cycle malfunctions the ice can quickly encase the system. A heat pump coil that is completely iced over will be unable to properly siphon thermal energy from the air, causing a drop in system output. Eventually, the ice can spread to other areas of the system and cause it to break down. Call for repairs if your heat pump is more than 50% covered in ice.

Short Cycling

Short cycling is when your heat pump turns itself on and off every couple of minutes. It can be caused by any number of things, from a damaged compressor to a short circuit between the thermostat and the system. What matters, though, is that it increases the amount of wear and tear on the system exponentially. If left unchecked, short cycling can shorten the lifespan of the heat pump by a number of years. Call a professional if you hear your heat pump turning on and off every few minutes.
