Your HVAC system works by pushing cool or warm air, depending on the season, through your ductwork with the help of a component called the air handler. An air handler, also known as the blower, is a large indoor fan that blows the air generated by your furnace or air conditioner into your home's ductwork for easy delivery of air into your home's living spaces. Maintaining your air handler unit is critical for your HVAC system's energy efficiency and your home and personal comfort. That being said, DK Hardware offers a wide range of air handler accessories so that your air handler unit is safe and sound for years. For example, our condensate cop drain pan float switch from Diversitech shuts off the system when water backs up in the drain line due to a clogged line. Our air handler foam block from Diversitech is a completely resilient, lightweight foamed plastic block that provides A/C air handler support in attic installations. You can also check out some more air handler accessories on this page and choose the one based on your requirement. '
