Heat pumps are built for warmer southern climates, but when freezing temperatures hit, they can struggle to keep up with the demand for heat. Before you call a professional, there are a few steps you can take to troubleshoot the issue and possibly save yourself time and money.

Common Heat Pump Issues in Freezing Weather

Here are some problems you might notice during freezing temperatures:

• The outdoor unit is frozen or iced over.
• Your system is blowing warm air but not hot air.
• The system is not running at all.

If you’re experiencing any of these issues, follow these steps before scheduling a service call.

Steps to Take Before Calling a Technician

1. Check if Your Outdoor Unit Is Frozen

A frozen outdoor unit is a common issue in freezing weather. Here’s what to do:

• Option 1: Switch to Emergency Heat Mode
  Activate the emergency heat setting on your thermostat. This will engage the indoor heat strips to provide supplemental heat while your outdoor unit defrosts. Note: Your home may not feel as warm as usual, but this will keep you comfortable until the unit can be repaired or fully thawed.
• Option 2: Use A/C Mode to Force Defrost
  Set your system to air conditioning mode for up to 15 minutes. This will reverse the refrigerant flow, heating the outdoor unit to melt any ice. Once defrosted, switch back to regular heat mode.

2. Assess the Air Temperature from Your Vents

If your system is blowing warm air but not hot air:

• This may be normal during freezing temperatures. Heat pumps are less efficient in extreme cold and often rely on auxiliary heat to supplement the demand.
• If the air feels uncomfortably cool, check your thermostat settings to ensure the system is running in heat mode and not set to fan-only.

3. Inspect the System’s Operation

If your system isn’t running at all:

• Check the power supply. Ensure the breaker hasn’t tripped and that your thermostat is powered on.
• Inspect the thermostat settings. Confirm it’s set to heat mode and the desired temperature is higher than the current indoor temperature.
• If everything looks fine and the system still won’t run, it’s time to call a professional.
