ACS Filters & Service

Old School Value, Expert Service, and Efficient Solutions 

ACS Filters and Services was founded in 1969 by Sam Viola. Today, our business, and flagship location on Grand Ave, still upholds the same mission : to serve Chicagoland engineers with the equipment needed for quality ventilation. 


ACS has a reputation for 55 years for heartfelt service and quality products at low prices. We have a large inventory of HVAC filters and belts. ACS’ service department delivers quickly and can schedule filter change-out services. Other services include free site surveys of cottonwood screens. 


Here to help you save money in your budget, while also ensuring your HVAC ventilation filter and belt needs are taken care of – ACS wants to make it easy to keep us as your preferred supplier.
