Running your furnace without a filter, even temporarily, can lead to significant issues. While it might seem like a quick fix, doing so can allow dust, debris, and allergens to circulate throughout your home, potentially damaging the furnace and reducing its efficiency. Additionally, a dirty furnace can pose safety risks, including overheating. It's essential to consider the type of filter your system requires and the potential costs of repairs if something goes wrong. Curious about the best practices for maintaining your furnace?
