Changing your HVAC filter is one of the simplest yet most vital parts of home maintenance. A clean filter ensures your system doesn't work overtime to pull air through a layer of dust, which lowers energy bills and prevents expensive mechanical breakdowns. Beyond protecting the equipment, it significantly improves indoor air quality by trapping allergens, pet dander, and dust. In extreme cases, a clogged filter can cause the evaporator coil to freeze. This can damage the compressor or lead to flooding when the coil thaws, potentially damaging floors and ceilings. Swapping a simple filter can save you thousands in repairs and energy costs. See less
