Metal-Air has been providing ammonia refrigeration services to various municipalities throughout Northern and Central Ontario for over twenty years. Our list of customers is long and growing. Our ammonia technicians have a combined one hundred years of service and have an extensive background in ammonia refrigeration, both in service and in construction.

Metal-Air has been involved in an extensive list of arena projects throughout Northern and Central Ontario, including the construction of new arenas from the ground up. Our capabilities on these projects include complete new ammonia refrigeration plants, brine headers and rink floor piping. Along with new construction, Metal-Air has completed several retrofit projects. These projects include but are not limited to the replacement of condensers, brine headers, chillers and compressors.


Our extensive inventory of parts and fully equipped service vehicles allow us to quickly respond to emergencies which in turn will limit the downtime of the plant. In the off season, Metal-Air does provide a full range of plant maintenance, including but not limited to 6,000 hour compressor maintenance, spring shut downs and fall startups.
