Serving the Greater Rochester Area and the Twin Cities since 1988

Since our humble beginnings in Rochester, Minnesota in 1988, K&S has grown to be one of the largest volume heating and air conditioning companies in Minnesota. We are honored to represent quality companies like Lennox and Carrier, but today's owners are demanding more...especially when it comes to warranties.

Due to our huge volume, K&S has been able to sit down with Daikin American Industry designers at their location, just west of Houston, Texas, and have furnaces and air conditioners built to our tough standards. Daikin's Texas location is the largest heating and cooling factory in the world. We are so confident in the K&S Diamond Series design, we can back each furnace and air conditioner with one of the strongest warranties in America.
