It isn’t unusual for a heat pump to ice-up in really cold weather, but it’s defrost cycle should kick on periodically to melt the ice. If the condenser unit of the heat pump is frozen up and the defrost cycle doesn’t melt the ice, turn it off. Make sure none of the return-air registers are blocked, and check the filter to make sure it isn’t clogged. If there doesn’t seem to be a problem with air flow to the unit, see more information at Heat Pump Cold Weather Problems or call an HVAC service professional.
The store scheduling was great - confirmed for an open date within minutes. My technician was thorough and patient in explaining and working through the resolve needed for my furnace problem. He was courteous and good-natured, which helped to calm my frazzled state over a unexpected HVAC repair. The tech took care in my home not to create or leave a mess. Finally, & more importantly, I felt that rate was fair and I didn't feel cheated at the end of it all. I was also pleased that I could put the expense on my Home Depot card. I'd rather not need it, but if I run into another problem, I would gladly use them again.
