About Us

Uncompromising integrity and a commitment to exceed your expectations. That’s what MCM Air stands for today.

Hi I’m Ryan Olson, owner of MCM Air. In 1976 when my father started the company, he was focused on building custom homes in the Oshkosh, Winneconne and all Fox Valley communities. Today MCM is the only Factory Authorized Carrier Dealer in the Oshkosh/Winneconne area.

NATE certification is the mark of technician excellence.


MCM Builders Inc began building custom homes in the area in 1976. Due to our customer-first approach and our emphasis on quality, the business began to grow. In 1990, MCM Builders started a heating division that began installing Carrier HVAC systems in addition to building custom homes. MCM Builders discontinued custom home building operations in 1992, so that they could focus solely on the HVAC division. At that time, they continued with the Carrier product lines, because of their reliability, as they moved exclusively into the heating, air conditioning and ventilation field.

Our original sheet metal shop was located in a rented building on Main Street in Winneconne from 1990 to 1994. With continued expansion, we moved our business outside the village in 1995 to our present location.
MCM Air Inc continues to serve the entire Fox Valley area installing quality Carrier products in both new construction homes and existing homes. Our extensive construction background enables us to design custom HVAC systems tailored to your individual comfort and energy savings needs. We accomplish that by installing customized products and systems that heat, cool, humidify, ventilate, and purify your indoor air. As we grow, we continue to emphasize superior workmanship, dependable service, and a customer-first approach, just as we have done since the early days of MCM Builders. We are caring people dedicated to providing quality solutions for you indoor comfort.

Recognizing Carrier dealers who exemplify leadership and management, customer satisfaction, expertise, business growth and operational excellence.

The President’s Award, started in 2007, is Carrier’s highest honor for its dealers.
