5332014328_365dfc0775_mIf you go any significant amount of time without cleaning your home, you’re sure to notice how much dust and dirt can accumulate all over the place. Although you might not notice it, dirt particles also float around your air and get caught in your furnace’s airflow. If that dirt ends up building up on your furnace, it can cause some significant problems. Today we’re going to talk about the effects of a dusty furnace and what you can do to keep your system clean!


How does dirt build up on your furnace?


As we mentioned above, dust particles get caught up in your home’s airflow and are sent through your furnace via the return ducts. Your air filter is designed to trap those dust particles so that they do not build up on your furnace. If your filter is clogged, dust particles will bypass your filter and build up on your system’s components.


In addition, if you skip out on annual maintenance for your furnace, dirt that would have otherwise been removed will accumulate in layers and significantly impair your system’s performance.


What are the effects of a dusty furnace?



    • Comfort problems. If dirt builds up on the outer walls of your heat exchanger, it will form a layer in between the heat exchanger and the air that’s blown over it. This means that the air that’s delivered to your home won’t be as warm as it could or should be.






How to avoid a dusty furnace


There are two simple things you can do to avoid dirt buildup on your furnace. First, make sure that you check and/or change your air filter once a month. Your filter is your furnace’s primary defense against dirt buildup, and it has to be clean in order to perform its job properly. Second, schedule a furnace tune-up every year. During your tune-up, we’ll clean your system and get rid of any dirt that might have accumulated on your system over the year.

Zach H came out because we had asked for a smart thermostat 2 years ago and we’re not given one. i mentioned to him that upstairs is always EXTREMELY HOT and he went up felt it and went above and beyond and racked his brain to fix it. he found the issue and was on top of it immediately for a problem he wasn’t even sent out for. you don’t find many people who do extra service. very thankful. it already feels 10x better!
