Why is my Furnace on yet I’m not getting any heat?

When the temperature falls in the wintertime, the very last thing you need is a furnace that appears to be operating but isn’t for pumping hot air through the vents. It can be incredibly frustrating if your furnace fails to perform correctly amid frigid weather. So, look for furnace repair in Cambridge, ON. Fortunately, the cause may be less complicated than you believe, and you may be able to resolve the issue on your own. Read below to know more about this issue.


The most common issue that could cause this problem is the thermostat. Near the bottom of your thermostat, there should be a fan switch. There are two settings on the switch: ON and AUTO. When the fan is turned on, it will continuously circulate air around the house. You may notice cold air coming from the vents as a result of this. 

When the switch is set to auto, the fan will only turn on once the air temperature has reached the desired level. To prevent cool air from repiping to your home, ensure the thermostat’s fan switch is set to auto.

Air Filter

Remember the last time you replaced your furnace’s air filter? If this is the case, the furnace’s filter is likely too dirty to function correctly. A filthy air filter might disrupt the airflow across the heat exchanger, causing it to overheat. If you don’t change the filter regularly, it may become clogged, reducing airflow. To improve interior air quality and avoid furnace problems, change your air filter once a month. So look for furnace repair in Guelph, Ontario, to get your filters cleaned or replaced.

Pilot Light

The operation of old furnaces is dependent on a set pilot light. The pilot light may be snuffed out and must be re-lit for the burners to produce heat. If you do not see a blue flame down at the bottom of your furnace, locate the reset switch and ignite the pilot again with a lighter.

Duck Leak

The air your furnace heats escapes into your attic or crawlspace when your supply ducting has holes or connection gaps. If there is a lot of duct leakage, the air coming out of your vents may feel colder or weaker than usual. Furthermore, leaking ducts impair the effectiveness of your furnace by requiring it to run longer and harder than necessary.

Heat Registers

Because you generally don’t pay attention to your heat registers, it’s difficult to discover when they’re mistakenly closed. This is all too frequent, particularly in a family with small children who enjoy playing with things. Make sure all the registers are completely open and not obstructed. If this does not work out, look for furnace repair in Cambridge, ON.

If none of the troubleshooting techniques described above solves the problem, it’s time to contact a professional to have your furnace problems diagnosed.
