I purchased a minority position in Frontier Refrigeration and Air Conditioning in 1979. With-in the next several years I purchased the shares of one of the funding partners ,to partner with the existing partner at a share split of 45%(mine) and 55% (his).Several years later I would purchase the remaining shares to obtain 100 % ownership.In the course of 100% ownership I would change the target markets for the company,seeing out new technologies that would provide niche markets for our company and to better position us for growth in coming years.

Laboratory and Hospital Refrigeration Service

Our first goal was to become established in the Hospital,Laboratory Refrigeration Marketplace, servicing the most sophisticated refrigeration equipment that was found in these specialized locations. We quickly became known for this type of service. New equipment manufactures would contact us directly before selling their equipment into Manitoba to ensure that we would be the company of choice to look after their equipment both during the warranty period as well as afterwards.This niche has cemented our reputation in Manitoba and ensures that we receive the calls to repair or modify the most complex HVACR problems for a variety and ever growing customer base.This department alone has grown to three full time mechanics to service the Manitoba Marketplace.


We were one of the first companies in Manitoba to embrace the newly emerging geothermal marketplace, designing and installing hundreds of residential and commercial projects with-out the assistance of numerous Design Softwares that are available today.Our company pioneered the Geothermal Application to Ice Rinks and Low temperature applications utilizing off the shelve geothermal products.The existing technology was found to be less efficient when utilized for the low temperatures required for Ice Rinks and other specialized low temperature applications.With that in mind,utilizing our vast refrigeration resources, refrigeration and geothermal experience ,we designed and marketed the first water to water heat pump specifically designed for this marketplace. The technology is now utilized by several manufactures to manufacture product for this market place.We are continually involved with research on new technology and ways to reduce energy use for our customers.

Design Build HVACR

Our company specializes in this concept to include full design and installation of HVACR Systems from one source,the contractor. Our Design Build experience has led us to complete complete chilled water systems for many larger clients including:

  • Interlake Regional Health Authority (Chilled Water Air conditioning)
  • Rehau Manufacturing (Process cooling)
  • Winpak (Process Cooling)
  • Winnipeg River Learning Center (Geothermal Design Build for 20,000 square foot learning center utilizing our geothermal designed/built water to water heat pumps)

Service work

We provide high level service work with exceptional follow up to ensure that our customers and their equipment is looked after in a professional manner, tailed to ensure a continuous stream of happy, satisfied repeat customers.

Preventative Maintenance

Designed to save the customer energy dollars by ensuring well maintained equipment and reduced downtime due to failures when equipment is not well maintained.Providing customers good value for their investment and providing the service that they have invested in.
