Our Story

Wilcox Heating and Cooling began with a simple idea: provide honest, dependable HVAC service without the high costs that homeowners have grown used to. Founded in 2025, WHC is a family-owned business built on more than 12 years of hands-on HVAC experience working in homes, new construction sites, and mechanical environments across Wisconsin.


After years of seeing customers pay too much for services that didn’t always deliver lasting results, we set out to do things differently. WHC was created to offer homeowners a better option — one where quality workmanship, fair pricing, and personal attention come first.
