Teresa, a city staff member, told the council the Hickman Community Center has experienced repeated mechanical failures since October 2025 and that mixed-metal corrosion—exacerbated by use of glycol and lack of routine pH testing—has driven repair costs. "These expenditures are a total of $52,894.53 in repairs to that system," she said, and noted the largest single repair this month exceeded $21,000.
The council approved two linked actions after discussion: a motion to authorize Grunwald to rework corroded components and add two automatic air-bleeding vents to the system (quote $25,695), and a motion to approve an annual HVAC service agreement with Grunwald for $9,679 beginning Oct. 1, 2026. Council members said the repairs are needed now and that the recurring service contract would help avoid emergency breakdown costs.
Teresa said the system was not designed for glycol and that introducing glycol without regular pH monitoring had "amplified that corrosion process" in mixed metals. She recommended replacing corroded sections with copper where appropriate and adding vents so air pockets do not have to be manually bled after repairs. Grunwald advised staff that, for the city’s system, certain components should be replaced and that a pressure-reducing valve would be preferable to a glycol makeup tank, although staff favored keeping the makeup tank for immediate leak detection.
Council discussion addressed scope control and budgeting. Staff said the $25,695 would be paid from the general fund and that change orders beyond the quote would come back through normal purchasing and claims reporting. Council moved to give the mayor administrative authority to approve work within purchasing-policy thresholds and directed staff to keep members apprised.
The first motion (approve the rework and add vents) passed by roll call. The second motion (approve the annual $9,679 service agreement, effective Oct. 1, 2026) also passed by roll call. The council noted the service contract would be included in next year’s budget documents.
The council’s vote sends the repairs to procurement and authorizes staff and the mayor to proceed within established purchasing rules.
