Service and Maintenance

Western Allied Mechanical's Service Division provides complete HVAC solutions. From service and repair to complete system renovations, we are prepared to be your contractor.

In 1975 Western Allied Service Company opened a Northern California office to expand our services already established in Southern California. In 2003, the Service Company joined forces with the Construction Company to form Western Allied Mechanical.

While others have strained with rapid growth and periodic contraction, we held true to our owner directed, moderate growth strategy that provides high levels of delivered expertise and quality.
