Electronic Air Cleaners

Electronic air cleaners are HVAC accessories that use charged collection cells to trap airborne particles as air moves through the system. They can help reduce dust, smoke, and fine debris in the air when they are set up and maintained the right way. Over time, the collection cells can get dirty, the charge system can weaken, or airflow can drop if the unit is not serviced. For related indoor air work, see our Air Cleaners & Humidifiers page and our Filter Replacement / Maintenance page. If you want more background, our blog post on indoor air quality solutions for Chicago residents gives helpful context.

Electronic air cleaner service starts with a system check to see whether the unit is cleaning air the way it should. We inspect the cabinet, collection cells, power supply, and airflow path. If the cells are dirty, we clean them and inspect them for wear. If the charge system is weak or the unit is not capturing particles well, we test electrical function and look for wiring or grounding issues. We also confirm that the HVAC system has the airflow needed for the cleaner to work properly. Once service is complete, we test the unit again and explain how often it should be cleaned and checked based on your home conditions.
