a.If your space has a heat pump system that provides both heating and cooling, it may seem like there are twice as many possible causes when something goes wrong.
A heat pump system does operate somewhat differently than a traditional air cooled air conditioner.
In some cases, there are issues you can prevent and problems you can solve on your own when you are aware of the heat pump troubleshooting steps. During the cold winter months, your heat pumps outside unit will sometimes be covered with a coating of frost on the side, or even light ice. In the winter, heat pump icing is often perfectly normal. Every so often, the unit will go into defrost mode to remove that frost. But, if the coils are encased in ice, or if the entire unit is covered with a thick sheet of snow and ice, this indicates a problem. This needs to be taken care of soon, because it could cause more damage beyond repair. You should never use a hard or pointy object to try to chip away the ice because fan coils are very delicate and can be easily damaged. Instead, use water from a hose to melt the ice.Removing the debris or snow and checking for leaking gutters that could be dripping water onto the unit, and repairing them is a good start to defrosting your heat pump unit. Call your HVAC service tech to troubleshoot defrost issues. If your heat pump is freezing up in the summer, either on the indoor or outdoor unit, you could have a refrigerant leak, clogged filter, or very dirty coils that are keeping heat from transferring as it should. In this case, you should turn the system off to prevent further damage, and contact your HVAC professional for assistance.
