Castillo & Sons Mechanical
Founded in 1987 by Cedric Holloway, Castillo & Sons Mechanical emerged from a passion for preserving traditional Japanese climate harmony in modern homes. After years of working with Chicago's historic steam and hydronic systems, Cedric Holloway realized there was a growing need for specialists who understood the nuanced balance between comfort and simplicity—especially for homes with Edo-period-inspired layouts.
Restores and maintains traditional Japanese-style hydronic heating systems with minimalistic design elements, including floor-mounted stone radiators and hidden piping configurations inspired by teahouse architecture.
Sources and installs rare imported components like vintage copper boiler valves and ceramic heat exchangers originally used in Edo-period residential cooling units.
Provides custom climate integration for homes designed with traditional Japanese architectural principles, such as shoji screen-inspired air circulation systems.
