Why choose Ray-Mac Mechanical for your service needs?

Founded in 1979 in Mt. Shasta California as a repair and service business, Ray-Mac Mechanical has grown to be the leader in the Heating, Ventilating, Refrigeration, Air conditioning and Sheet Metal Fabrication field for the California North State. As a locally owned and operated business we provide a wide range of services for our commercial, residential and industrial clientele. At Ray-Mac we boast one of the most experienced and complete mechanical staffs in our geographical area. We are dedicated to providing the most up to date diagnostic tools and training to our service staff. With over 50 years of combined service experience we have the ability to properly diagnose and repair any type of equipment. We budget a large portion of our yearly continuing education dollars keeping up with the latest information and techniques in our field. Proper repair is always more important than selling new equipment. Using properly trained service technicians with the most up to date diagnostic equipment most units can be repaired to normal operating conditions for far less than replacement. This is our goal.
