  • How does mini-split deep cleaning affect indoor air quality?

    Mini-split cleaning is key to improving indoor air quality, along with duct cleaning, heating system maintenance, filter changes, and proper ventilation.

    According to NADCA, a typical single family home accumulates up to 40 pounds of dust, dander, mold, and chemicals annually through everyday living. Think of your heating system as a pair of lungs, breathing air in and out continuously. The contaminants are pulled into the heating system and recirculated back through the house 5 to 7 times per day. While many particles are excluded by the furnace filter, over longer periods of time, this re-circulation causes a build-up of contaminants in the duct work. This can aggravate asthma or allergies and potentially shorten your furnace’s lifespan.
