As the weather gets colder, we’re going to be turning on our heating systems across the city. While it may seem daunting, understanding the inside of your furnace will help you make the best decisions this winter. Knowing the basics will give you everything you need to take care of your furnace. When it comes to the deeper technical details, trust the experts here at Homesense to take a look. Read on for the three most important components of your furnace.


Blower Motor

The blower motor is the main component that circulates air throughout your house. You’ll find it directly next to your air filter. It communications with the control board attached to it, which in turn communicates with your thermostat. The blower motor works to circulate air in both the summer and winter. Because of this, it can be a major repair if it does happen to break. One of the best things you can to take care of your blower motor is to change your air filter regularly. When your air filter gets dirty, the blower motor will have to work harder to circulate air, leading to a potential costly repair.


Inducer Motor

This second motor is also incredibly important within your furnace because it helps make your breathing air safe in your home. The inducer motor works to remove combustion from the air before it goes in to your home, ensuring that you don’t have exhaust in your breathing air. If you look at your furnace, you’ll see a PVC pipe, which is where the combustion air travels and is removed from your home. The inducer motor can be found between your blower motor and your heat exchangers. It’s a good bit smaller than the blower motor.


Heat Exchangers

This third and final basic component of your furnace is perhaps the most important. It has the biggest impact on both your heating and overall health. The heat exchangers are a handful of pipes that create the flames that heat your home. When the air starts to circulate, the control board of your furnace will communicate with the heat exchangers to start the flames. The air that goes through those flames is the warm air you feel vented into your home. Heat exchangers can wear out over time, so it’s important to have routine maintenance to have them looked at. If they do get a crack in them, it can be fairly dangerous to your home.


We believe it’s just good sense for homeowners to know these things. With a greater understanding of your system, you can be more equipped to make the best decisions for your home. Need help with your furnace? Give us a call at 317-203-8149 or schedule an appointment online.
