Never Compromise on Quality When It Comes to the Air You Breathe

Forced air systems, including furnaces, air conditioners, and heat pumps, circulate warm or cool air throughout your home via ducts and vents. These systems utilize filters to prevent dust and debris from being distributed along with the conditioned air. These filters not only enhance indoor air quality but also safeguard your forced air system.

When filters become overly clogged with particles, they diminish your system's efficiency, leading to increased heating and cooling costs, due to the hindered air movement from your heating system into your home or business. A severely clogged filter can cause a build-up of hot air near your heating system, triggering its emergency shut-off mechanism and leading to intermittent operation. Furthermore, clogged filters can exacerbate the presence of mold, dust, and other allergens in your home.
