We are still in the dead of winter and using our furnaces around the clock to keep our homes warm. When your furnace starts to blow cold air from the vents, it isn’t something that you want to leave alone in hopes that it starts to work properly. You need to start troubleshooting right away to attempt to get to the bottom of the problem. There are some problems that can be fixed when you start to investigate the problem a little further. Air Supply Heating & Air Conditioning is here to share some tips to help you get to the bottom of what is going on with your furnace.
Dirty Furnace Air Filter
One of the first things you should always check when you’re having issues with your heating system is the air filter. When the filter is dirty, your furnace can’t get the airflow that is needed for it to work properly. You should be changing this filter on a regular basis to keep your furnace working efficiently to warm your home.
You should also check the thermostat to make sure all the settings look like they should. Sometimes, you may have the fan turned on which will leave your fan blowing around the clock. This can lead to cold air coming from your vents. You also need to make sure your thermostat is set to heat your home and the temperature is right.
Furnace Pilot Light is Out
The pilot light needs to be lit when the furnace is on to heat your home. If the light is out, you will have a problem. Sometimes, the light may have just gone out, but there are also situations where the light isn’t getting lit properly to begin with. If there is a blockage of soot and dirt, or a malfunctioning thermocouple, you could run into a furnace that is unable to heat properly.
Clogged Condensate Line
Any high efficiency furnace is going to produce a byproduct of condensed liquid. When this happens, you usually don’t see it because it is drained away. Sometimes, there is a blockage in the condensate drain line and it leaves your furnace blowing cold air and water leaking from it. Removing the blockage can help fix the problem.
Low Gas Supply
Many furnaces are powered with natural gas. If this is the case for yours, you need to make sure there isn’t a problem with the gas supply line. Make sure the gas line hasn’t been shut off for any reason and that the gas valve isn’t closed. If neither of these problems are present, you may have a blockage in the line.
