What type of fuel your furnace uses for this combustion. This series of heated coils (called a heat exchanger) has a fan (called a blower motor) which blows your houses’ air over them and into your air ducts where it is dispersed throughout your house. This simple process, regardless of what type of fuel you use, is how your furnace is able to blow warm air into your home.

If the furnace is not getting power, check the furnace circuit breaker or fuse as this might also be an issue.
On the other hand, the unit may be clogged with dirt and dust and you may be able to fix that yourself but may likely need special attention to unclog the debris and dirt from the components.
