Reasons why your furnace might be blowing cold air

Cool breeze in the air is an indication of the advent of sweater weather, hot cocoa, and bundling up in cozy duvets. As the temperature falls outside, your furnace works hard to keep your house toasty warm. However, it can sometimes give you a little unpleasant surprise by greeting you with cold air.

Here are the top 5 reasons why your furnace might be blowing cold air and when should you call Furnace repair Barrie! 





1. Incorrectly set thermostat


When the furnace is cranked up for the first time after the season has changed and it’s blowing cold air instead of warm, it can incite some panic. Our first instinct might be to check the thermostat which, in many cases, is set incorrectly. 

Make sure your thermostat fan setting is AUTO and not ON. A thermostat with an ‘on’ setting means the fan will run continuously even if the furnace is not working. 


2. Clogged condensate lines


The newer and latest furnaces have condensate lines that help to remove moisture created during the heating process. Clogged condensate lines could prevent your furnace from igniting and can cause cold air coming out of your vents. A furnace repair Barrie technician will help you identify this problem.

 

3. Not enough gas supply


Not getting an adequate amount of gas supply might also be a reason why your furnace is not working properly. Furnaces are designed to shut off for safety reasons, one of them is inadequate gas supply. In this case, you should look for furnace repair Barrie and seek professional help. 


4. Overheated furnace


Air filters usually collect a lot of dirt and debris over time. If not cleaned regularly, the compromised airflow can cause the system to overheat and turn off. Other reasons like malfunctioning parts, old and weary furnaces, can also cause the furnace to overheat. 


5. Leaky air ducts


Air ducts carry warm air from the furnace to the entire house. Over time, these may develop a few holes or cracks in them through which the warm air starts to escape. You will need a professional’s help in this case. 


Cold air coming out from the duct is undesirable by many so the best way to avoid it is to be proactive rather than being reactive. Regular maintenance and cleaning schedules by Zeeco Services LTD might save you from the trouble of finding a technician at the last moment.
