Aerators run 24/7 and need annual servicing: filter cleaning, diaphragm replacement (3-5 years), and motor inspection. Our Cincinnati technicians service aerators across Hamilton, Warren, and Clermont counties.
More detail
Aerator maintenance schedule for typical Cincinnati ATU systems (Hiblow, Air-Tech, Norweco brands). Annual: clean intake air filter, inspect diffuser stones for clogging, verify alarm-test functionality, check chlorine tablet supply if equipped. Every 3-5 years: replace aerator diaphragms (cost $80-$200 for parts plus 30 min labor). Every 5-7 years: replace aerator motor or rebuild ($200-$500 parts plus 1 hour labor). Annual service contracts run $200-$400 in Greater Cincinnati and typically include all routine items plus a service log. Some Ohio counties (parts of Hamilton, Warren) require ATU systems to have an active service contract on file with the county health department; check before declining service. Failure of the aerator triggers an alarm; sustained alarm (more than 24 hours) typically indicates motor failure or power issue and requires service dispatch. Cincinnati ATU service-contract value: the typical $200-$400/year service contract pays for itself by catching diaphragm wear and motor degradation early, preventing the larger $400-$800 emergency-replacement bill that comes from running an aerator to failure. Some Hamilton County and Warren County ATU permits require a service contract on file; check the original installation paperwork before declining service.
