How to Troubleshoot a Furnace Blowing Cold Air

The middle of the winter season is a time when you don’t want your furnace to be blowing cold air. During the harsh weather conditions, if your furnace gives way, you should contact an HVAC repair in Yucaipa to troubleshoot the issues. Some issues can be easily fixed. On the other hand, some problems might require professional intervention.

Steps to troubleshoot when your furnace is blowing cold air

Below are a few ways by which you can troubleshoot your furnace blowing cold air –

    1. Check the fan settings of the thermostat
      If you have set the blower fan of the furnace to run non-stop, it will be working even when the system is not working to generate heat. There is a probability that the furnace is blowing cold air due to incorrect settings. To correct it, you will have to check the fan settings of the thermostat. Currently, the setting would be ON. Ideally, the fan setting should be kept as AUTO. Once you update the setting, the fan will run only during the heating cycle of the furnace. It will not be pushing cold air outside the heating cycle. If the issue persists, you can reach out to HVAC repair in Yucaipa for a solution.

    2. Checking the air filter of the furnace
      Within the furnace, a clogged air filter might be an obstacle to the air movement. As a result, the temperature within the furnace might rise. If the system becomes too hot, the limit switch will shut down the unit and the heating cycles. Cleaning or replacing the dirty filter might prevent cold air from blowing through the furnace. Follow the below steps to replace the air filter –
      • Search the furnace for the filter compartment and open the access door.
      • Take out the old filter and dispose.
      • Insert a new filter of the same dimensions.
      • Close the access door.
        If your furnace is still blowing cold air, it might be the correct time for you to call the heating service Hemet.

    3. A broken control panel of the furnace
      If the furnace is blowing cold air, there are high chances that the control panel is broken. Resetting the system should solve the problem. You can try switching the system off and then turning it on after 5 minutes.

    4. Unit surrounded by standing water
      Condensation takes place around a high-efficiency furnace. The condensate drain line takes out the condensation from the system. Standing water around the system indicates that the condensate line is blocked. You can try cleaning the clogged drain by locating the condensate drain pan and then cleaning it. Attach a wet vacuum to suck out the object blocking the drain. Heating service in Hemet can help you in understanding the problem and dealing with it.
