Janesville Winair is part of Winwholesale, a group of independent corporations that are wholesale distributors of plumbing supplies, industrial equipment, heating and cooling materials, electrical equipment, waterworks supplies, pumps, fasteners, and electronics. Each of our locations is privately owned and operated but held together by a central philosophy of opportunity, responsibility and pride.

We sell HVACR (heating, ventilation, air conditioning and refrigeration) products to qualified service people and contractors. We are also involved in sizing and design of new and replacement systems.

We are located at 4303 Capital Circle on Janesville's northeast side, easily accessible from Interstate 90 or Highways 11 & 14. With more than 13,000 square feet of warehouse space, we are able to stock a broader and deeper inventory to suit your needs.
