You need your furnace to work when it is cold outside. If your furnace didn't seem to be working right, there are a few primary reasons why your furnace may be underperforming.
Reason #1: Dirty Filter
One of the main reasons that furnaces underperform is simple: they have dirty air filters. When an air filter is clogged up with dust and pollen, not enough air will be able to get through the air filter, and thus not enough air is being heated by your furnace and pumped into your home. When your furnace is acting wonky, the first thing you need to do is go and check the air filter. You should check the air filter about every other month to prevent this from becoming an issue in the first place. You should always keep a spare air filter on hand so you can easily switch out your air filter when it gets used up. This will keep the air in your home clean and will allow your furnace to function properly.
Reason #2: Bad Thermostat
Your thermostat is kind of like the brain of your furnace. The thermostat sends your furnace the information that it needs to determine how to heat the air and how much heated air needs to be sent to your home in order to keep it warm. When a thermostat starts to malfunction, it can impact the performance of your entire furnace.
If you think your thermostat is not working correctly, it is time to upgrade your thermostat. Upgrade to a smart thermostat that will allow you to great control over the temperature in your home. A smart thermostat can give you greater control over your energy output, as well.
Reason #3: Bad Blower Motor
The blower motor is responsible for blowing air through your home. When the blower motor fails, your furnace will still turn on and create hot air; however, that hot air will not be circulated through your home.
It is normal for the motor to experience issues if you have an older furnace. Bearings may wear out and belts may fail. A blown blower motor can generally be avoided through a yearly maintenance inspection. However, if your furnace is turning on but is not blowing hot air, you need to call in an HVAC technician to come and fix your blower motor.
If your furnace is not working properly, check the air filter, see if the thermostat is working properly, and check the blower motor.
