4 Common Wintertime Heat Pump Issues in Sterling, VA
Here in Sterling, VA, the temperature drops into the 20s during the winter, so you’re going to need your heat pump working to keep you warm and comfortable. Find out about four common problems that a heat pump can experience during the winter.
1. Defrosting Malfunction
Modern heat pumps have defrosting systems that can clear ice from either their indoor or outdoor units. According to the International Association of Certified Home Inspectors, the defrost cycle should last from about 30 seconds up to a few minutes. The idea is to get the frozen portion of the heat pump to at least 57 degrees Fahrenheit and then return to the heating cycle.
If the defrosting cycle doesn’t work, then the heat pump will stay frozen. At that point, you’ll need a professional to repair your heat pump.
2. Debris in the Outdoor Condenser Coil
The condenser coil’s job is to absorb heat from the outdoor air and transfer it into your home. If there is debris on the coil or in the system, then the outdoor unit could freeze.
3. Weather That’s Below Freezing
Below freezing, especially in cases of snow or sleet, your heat pump might struggle to pull heat out of the air. This usually results in freezing, which interferes with your heat pump’s ability to warm the inside of your home. If this combines with a defrosting problem, then it’ll be a job for an expert to fix. Many heat pumps have a heat strip to help them produce warm air when temperatures dip below freezing.
4. Stuck Reversing Valve
This problem isn’t intrinsic to winter; it can happen throughout the year. It’s especially irksome in winter because it can result in your heat pump blowing cold air when it’s cold outside. Fixing or replacing the reversing valve should fix the issue.
