The Hamilton County Courthouse was initially plagued by temperature fluctuations between the 60s and mid-80s due to inefficient steam heating equipment that could not make precise adjustments, leading employees to open windows and rely on electric heaters to combat overheating.

To address this issue, the outdated steam heating system, which included corroded pipes and boilers, was completely replaced.

A new combined heating and cooling system was installed, featuring updated equipment such as a new hot water heating boiler, a water chiller for air conditioning, new piping, and an advanced temperature control system.

This system ensures that each room has independent heating and cooling, replacing the original cast iron radiators and single building-wide control with individual thermostatic controls.

Additionally, window air conditioners previously used in offices were eliminated, and the new system now provides adequate cooling to both the corridors and offices.

The contract for the renovation was awarded to McIlnay & Company of Central City, with a construction agreement established on July 1, 1989, for $182,411.00.

However, construction faced delays when asbestos was discovered in the pipe tunnels, necessitating its removal before work could commence.

State inspectors also identified issues with the existing electrical service entrance, prompting a change order to rectify this concern.

Furthermore, upon examining the existing boiler, insufficient foundation support was identified in the boiler house, leading to an additional change order.

Ultimately, the renovation was completed on May 11, 1990, with the final project cost adjusted to $193,434.00.
