Just like any piece of hardware in your house your air ducts require some maintenance throughout the year to keep your home’s air clean, and your HVAC system operating at its peak efficiency. Air duct cleaning can save you anywhere from 25% - 40% on your energy bill. Even if you’re one of the lucky people and dust doesn’t cause an allergic reaction, its unsightly and can still deteriorate the air quality in your home – the components found in dust can affect your lungs and overall health even if you do not have a dust allergy. How much dust you have in your home depends on several factors including where you live, the season, how many people live in your home, whether you have pets, and how much you clean.
