A problem with your heat pump could be stressful during the chilliest winter conditions. According to the U.S. Energy Information Administration, electricity and natural gas are used nearly equally in the residential sector of Georgia, meaning that both furnace and heat pump problems are of significant importance in the Chamblee area. Troubleshooting steps for both types of systems are nearly identical.

System Controls

Whether your heater blows cold air or fails to turn on, your first point of inspection is the thermostat. Verify that heat is selected, and check the exact temperature settings. You may be dealing with a weak battery, making a quick battery test an important diagnostic step as well. Even if these steps do not reveal a problem, you could be dealing with a malfunctioning thermostat, which would require a professional diagnosis.

Filter and Vents

If the system controls are fine, you will want to check to make sure that the filter is clean and that the vents are not blocked. If your heating system has been delivering cold air or inadequate air supplies to part or all of the house, there could be a leak or a blockage. This is more likely the case if the problem is only identified in a small portion of the home. If your heating system has been short cycling, a dirty filter could be an issue, causing overheating that leads to quick on-and-off activity.


Both a furnace and a heat pump require electricity to operate. Although the power in your house may seem to be fine, a blown fuse could cause the heating equipment to stop working. Check the fuse box for a tripped switch, making any adjustments as needed.
