Our Duct Cleaning Service Will Keep Your Indoor Air Clean At O’Brien O’Comfort your home’s Indoor Air Quality (IAQ) is important to us. Having a clean, properly functioning heating, ventilating and air conditioning (HVAC) system is vital to maintaining a healthy living environment. Air duct cleaning allows air duct system to run more efficiently than a dirty one, resulting in lower utility bills and a cleaner, less dusty home.Our air duct cleaners check for dust, dirt, pollen, animal dander and other airborne contaminants that are pulled into your HVAC system every time the furnace or air conditioner runs. Over time as your HVAC systems run they build up dust, dirt, pollen and debris inside your ductwork, making your air duct system susceptible for the buildup of mold spores, bacteria, fungus, mildew and other microbes, which are then re-circulated through your home. O’Brien O’Comfort uses a Power Vac HEPA Unit to remove these undesirables from your system giving you Peace O’Mind.
