If your HVAC has been operating for some time without attention, it could be circulating odors, dust and other contaminates. SERVPRO Franchise Professionals routinely inspect the heating, ventilation and air conditioning unit (HVAC). Keeping them clean can extend the life of the equipment. This can in turn save you money and give you cleaner air to breathe. However, air duct cleaning is not always necessary. SERVPRO Franchise Professionals will make recommendations about the best way to address any indoor air quality concerns.
