You’ve been running your heater for hours trying to heat up your house but you can’t get rid of that frigid air. You reach up to feel the air coming out of the vent and in shock you feel cold air! Before calling an HVAC company, here are a few things you can try.
Check the Thermostat
Now that you know there is cold air coming out of the vent, check out the thermostat. If your home is warm and the thermostat is at the temperature you set it for, the problem may be with the thermostat itself. Check to make sure the settings are right and the thermostat is set for “auto” and not for “on.” If the switch is set for “on,” the fan on the furnace will continue to blow even if the heater is not actually heating the air.
Change the air Filter
A dirty air filter is a quick and easy fix, but it can cause furnace issues if not regularly changed. Once an air filter becomes dirty and clogged, it restricts air flow into the furnace. This restricted airflow can cause the furnace to overheat resulting in a safety control shut off of the burners.
Other Possible Causes
Have you tried both of the troubleshoot options above and still feel cold air coming out of your vents? The most efficient, effective, and cost friendly option is to have a heating and air company come to your home to take a look. Superior Water & Air offers a free estimate and is available 24 hours a day, 7 days a week, 365 days a year. Here are a few other reasons that may be the cause behind your home’s furnace not working properly.
Ignition or Pilot Light Issue
If the ignition system is not working properly, it would hinder your furnace’s ability to light. This means that the furnace is not lighting the fuel, which leaves you stuck in a cold house.
Inadequate gas Supply
Your gas supply could be turned off or there could be a problem with your gas line. If your gas line isn’t supplying enough gas to your furnace it can lock down as a safety mechanism.
Major Duct Problems
If you have large leaks or holes in your air ducts, this could be another possible cause of the cold air coming from the furnace. Cold air from the attic or crawlspaces can then get into your ducts and turn the air cold before it reaches the vents to each room.
The newer high-efficiency furnaces have condensate drain lines, which remove the water that is built up during the heating process. If this line becomes clogged, it can activate a safety switch that will prevent the burners from lighting.
Still Blowing Cold Air?
After your attempts to fix your furnace and finding the possible cause of the cold air, it may be time to get your furnace fixed.
