Duct Unlimited
Duct Unlimited was formed in 2021 resulting from what we saw as a need of HVAC/General Contractors for quality, made-to-specifications ductwork with quick turnaround times.
As owners of a full line sheet metal fabrication shop and an air conditioning company since 1964, we decided to get into the manufacturing side of the business.
From straight pieces of square duct to a large assortment of fittings, lined or unlined, we would love the opportunity to quote your project.
Capabilities
We currently have the following tools at our disposal:
