If your heat pump struggles to heat in winter or cool in summer, there may be issues with refrigerant levels, compressor performance, airflow, or thermostat/control settings.
Grinding, squealing, rattling, or loud clicking—especially during mode changes or defrost—can indicate loose components, motor or fan issues, or a failing reversing valve.
Rapid short cycling or failure to switch between heat and cool can point to thermostat faults, refrigerant issues, defrost control problems, or an improperly sized system.
Cool air in heat mode or warm air in cool mode may indicate low refrigerant, a reversing‑valve problem, outdoor unit icing, or duct/airflow issues.
Visible ice on the outdoor unit that doesn’t clear, or frequent/extended defrost cycles, can indicate airflow restrictions, low refrigerant, or defrost control issues that need attention.
In a northern Indiana winter a heat pump does a few things that look like trouble but are normal, and a few that mean it needs a repair. Knowing the difference saves you a service call, or tells you when to make one.
On cold, damp days frost builds on the outdoor coil. Every so often the heat pump reverses for a few minutes to melt it: the outdoor fan stops, steam may rise off the unit, and the vents can blow cooler air for a short time. A light coat of frost that clears after a defrost cycle is the system doing its job.
Call us when the outdoor unit is encased in solid ice, when ice stays on the coil after a defrost cycle, when the top of the unit or the fan is iced over, or when the system goes into defrost again and again. The usual causes are a failed defrost control board or sensor, low refrigerant from a leak, an outdoor fan motor that has stopped, or airflow blocked by a dirty filter or coil. Turn the system off at the thermostat instead of chipping at the ice; the coil fins bend easily and a damaged coil turns a repair into a replacement.
Most heat pumps have backup heat: electric heat strips in the indoor air handler, or a gas furnace in a dual-fuel system. Backup heat comes on during defrost and on the coldest nights, when the heat pump alone cannot hold the thermostat setting, and the thermostat shows AUX while it runs. Electric strip heat costs more to run than the heat pump, so it shows up on your NIPSCO or AEP Indiana Michigan Power bill. If AUX stays on most of the day in mild weather, the heat pump side usually has a fault. The EM HEAT setting is meant for a failed outdoor unit, not for everyday use; if you have switched to it, call us.
A few minutes of cool air during defrost is normal. Cool air that keeps coming after you confirm the thermostat is set to heat points to a reversing valve stuck in cooling, a low refrigerant charge or a failed backup heat strip, and it needs a diagnosis. If the heat is out on a cold night, our emergency service page explains how to reach us. A fall tune-up under the Climate Shield maintenance plan checks the defrost controls, the reversing valve and the refrigerant charge before the cold sets in. Call (574) 633-4557.
