Why Is My Furnace Blowing Cold Air?

Your furnace seems to be kicking in okay, but the air blowing through your registers is not that warm. It seems the furnace is on a lot more than it should be and you’re still feeling chilly! Something is wrong with your heating system. Friesen’s Climate Control in Edmonton are heating and air conditioning specialists in Edmonton. They share some information to help you troubleshoot the problem.

Here are some things you can check when your heating system isn’t blowing warm air:

Thermostat Settings

Some digital thermostats sometimes have separate settings for the blower and for the heat. That means that sometimes your furnace is set to go on, but not set to actually heat up and blow warm air into the home. Some  older thermostats have an icon for the fan blower and a different one for the heat. The heat icon usually looks like a little flame. Make sure both the heat and the fan blower are on. Your thermostat has this setting so you can choose to circulate air in the warmer seasons your home without heating it.

Furnace Filter

The filter works hard to keep dust and debris out of the heating system and it needs to be replaced regularly. Dirty filters can restrict the airflow of your furnace. When airflow is restricted, it makes the furnace work harder and it can become inefficient and even unable to do the job properly. Sometimes a clogged filter can cause a furnace to overheat and even break down. When the furnace overheats, a safety device can turn the furnace burners off and the blowers will keep blowing cold air to cool the furnace down to a secure level.

Pilot Light

The pilot light is a small gas-flame inside the furnace that ignites the fuel. You need to make sure that the pilot light has not blown out, which could be a possible reason for your furnace delivering cold air. To fix this, check that the gas valve is on, then follow the instruction manual to safely reignite the pilot light. Often the instructions to do this are right on your furnace or on the inside panel. If it lights and your furnace starts to work properly, than you’ve fixed the problem. Otherwise, contact the pros at Friesen’s Climate Control. Learn how to light a pilot light.

Gas Supply

If a sufficient amount of gas is not supplied to the furnace, it may cause your furnace to stop working for safety. If you think you have an issue with your gas line, call in your local gas provider to investigate the issue for you. If you suspect a gas leak, leave the house immediately until the professionals have investigated and remedied the situation.

Leaky Ducts

It’s highly possible that your furnace may be doing its job correctly, but the ductwork isn’t supporting it. Large holes and leaky spots in your duct system may be discharging the warm air before it can even get to each room in the house. An HVAC professional can inspect and repair your faulty ducts.
