When cooler temperatures arrive and Texans turn on their heating systems, being confronted with cold air instead of warm air can be a surprise. To make sure you have a warm and cozy house, you will want to uncover the reason your furnace is causing you to feel cold air blowing from your vents. Some issues your heating system might have are easy to fix; but others require qualified professionals to resolve. Read on for some of the things you should investigate about your furnace to stop the cold air from blowing
Your Thermostat is Not Functioning Correctly
Your thermostat transmits your temperature choice to the furnace. If the thermostat isn’t working correctly, your furnace could be blowing cold air because the temperature is either being communicated improperly or not at all. Repairing or replacing your thermostat might be necessary to ensure that the temperature setting is accurately transmitted to your furnace. A professional HVAC technician can assist you with repair or replacement of your thermostat, including offering guidance regarding upgrades such as to a smart thermostat for programmable control of the indoor air temperature.
The Setting of Your Thermostat Fan is Wrong
If you have a furnace with a blower fan that’s set to run continuously, it will run regardless of the temperature setting. This means that your furnace could be blowing cold air because of the set temperature has been achieved according to your thermostat. Check the fan setting on your thermostat and make sure it is set to “auto,” rather than “on.” The auto setting allows your furnace to run the fan only during a heating cycle; so cold air does not cycle through your vents at other times.
Your Furnace Control Panel is Broken
Another reason your furnace might blow cold air is if the electronic control panel is broken. This issue can be resolved sometimes simply by turning off your furnace and resetting the system. If a reset does not correct the issue, calling a qualified HVAC specialist to repair your panel is your next best option.
Your Furnace Air Filter is Dirty
If your furnace has a dirty air filter, air flow might be impeded. If that happens, the temperature inside the furnace will rise and cause it to overheat. An overheated furnace will result in a furnace shutdown. Replacing the filter is usually the way to stop cold air from blowing through the system. If you need help finding and replacing your filter, contact a skilled HVAC technician.
Your Pilot Light Is Out
If your furnace pilot light is out, your furnace will blow cold air due to no combustion of fuel. If you relight the pilot light the fuel will burn again and heat will be restored. If you are
unable to relight the pilot light or if it continues to go out, you should call a proficient HVAC technician for assistance.
You Have Leaky Air Ducts
Your furnace might be blowing cold air due to air duct leaks. Leaky air ducts let heat escape; so the air that emanates from your vents isn’t as warm as it should be. Duct leaks can be repaired to resolve heat loss. You will likely have to call in a professional to make the repairs.
