MSI HVAC is a family-owned, multi-state distributor and manufacturer of heating and air conditioning products, serving the contractors of the Southwestern United States.

MSI was founded in 1986 in a small warehouse in Brea, California. After several years and several moves, the company embarked on a growth plan expanding to other California cities as well as Las Vegas, Nevada. Today, we have a collective 175,000 square feet of manufacturing and warehousing space and more than 125 people engaged in the distribution of heating and air conditioning equipment and supplies.

MSI’s business is built on long-term commitments with customers and suppliers, and honesty and integrity in all matters. We proudly offer Honeywell and Armstrong Air products at all of our locations.

We are dedicated to the most efficient use of time and resources to continually identify and satisfy our customers’ growing needs. We invest heavily in the most advanced technologies and equipment automation and, most of all, in our associates. MSI is prepared to put resources where they are needed.

We would count it an honor to be your supplier of choice.
