Double Furnace In Your Home? DIY Air Filter Basics


DIY Air Filter | Double Side Furnace

You most often create it by using a box fan and a top-quality filter (such as MERV or HEPA) that you can easily attach to the fan. 

Some homes, especially two-story houses, may have two furnaces to address the challenges of effectively heating and cooling a multi-level living space. Two-story homes often experience temperature variations between the upper and lower levels due to the natural tendency of warm air to rise. By using two furnaces—one for each floor—homeowners can achieve more precise temperature control and ensure even warmth distribution throughout the house.

This setup allows them to optimize energy efficiency and comfort, ensuring that each level maintains its desired temperature without overworking a single furnace and potentially leading to more balanced heating and lower utility costs. Find us on Google Maps
