Mason-Dallas, Inc. was founded 1978 based on a philosophy of providing superior customer service and the highest quality engineering design and technical products to the HVAC industry for vibration/isolation, seismic and noise control. At the time of our incorporation, Mason Industries was our sole source supplier for these products and continues to be one of our most valued business resources. This and the other long-time relationships with our vendors are testimony to our commitment to providing quality service and support to our business associates. This same dedication carries through to our customers. Most of our initial customers remain our customers today.

​ “Quality Products, Customer Service and Added Value” remain the cornerstone for Mason-Dallas. In order to provide solutions in response to our customers’ needs a wide range of HVAC, hydronic, vibration/seismic and noise control solutions have been added to the Mason-Dallas line of quality products.
