Northern Weathermakers HVAC — Serving Chicagoland Since 1949
An employee-owned commercial HVAC company built on integrity, craftsmanship, and a commitment to treating every customer like family.
Our Story
On February 1, 1949, William L. Hochschild, Jr. founded Northern Refrigeration and Engineering Company. The company was built on a commitment to dependable service, technical expertise, and long-term customer relationships—principles that continue to guide Northern Weathermakers today.
We are an employee-driven company. Our technicians, engineers, and project managers take personal ownership of every job they touch. That pride in workmanship is what sets Northern Weathermakers apart — and it's why our clients keep calling us back.
We serve medical facilities, manufacturers, multi-tenant buildings, retailers, warehouses, and more — bringing the same hands-on attention to a 1,000 SF office as we do to a 500,000 SF industrial campus.
What We Stand For
Integrity First
We give honest assessments, fair pricing, and transparent communication — before, during, and after every project.
Craftsmanship
Our in-house sheet metal, piping, and engineering teams ensure that every installation is built right — not just built fast.
Responsive Service
We offer 24/7 emergency response because HVAC failures don't keep business hours. When you call, we answer.
Family Culture
We treat our employees and customers like family — because long-term relationships are how we've survived and thrived for over 75 years.
