History

American Mechanical Services (AMS) is one of the nation’s leading providers of commercial heating, ventilation, and air conditioning (HVAC) maintenance, repair, replacement, and new equipment installation, as well as plumbing and related services.

AMS began in 1997, when American Residential Services (ARS) purchased approximately 25 independent contractors and consolidated them to create a commercial HVAC arm. The newly acquired contractors were already well established companies with years of experience in the HVAC industry. This allowed AMS to quickly assimilate into each market. Accordingly, it was during this period that the AMS entities were acquired and reorganized into our current entity locations, which include:

• Air Conditioning Associates, Inc. d.b.a. ACA – Denver Boiler
• American Mechanical Services of Colorado Springs, L.L.C.
• American Mechanical Services of Denver, L.L.C.
• American Mechanical Services of Houston, L.L.C.
• American Mechanical Services of Maryland, L.L.C.
• American Mechanical Services of Texas, L.L.C.
• AMS Mechanical Services, L.L.C. d.b.a. AMS Mechanical Services of Indianapolis, L.L.C.
• Anderson Air Conditioning, L.P.
• Southcoast Heating & Air Conditioning, L.P.
• Tri-Pacific Heating & Air Conditioning, L.P.

In 1999, AMS was acquired by ServiceMaster. Each AMS company became a wholly-owned subsidiary under the ServiceMaster / AMS operating division rubric. During this period, Ed Dunn and Dave Schellhardt served as key officers of the ServiceMaster / AMS operating division and played significant roles in shaping the AMS brand as an industry leader.

In 2006, Dunn and Schellhardt formed a single-purpose parent company to acquire AMS from ServiceMaster. Thankfully, AMS has enjoyed its most successful years under the watch of Dunn and Schellhardt.

Collectively, AMS has an average of 30-plus years of industry experience. This kind of success and longevity can only be attributed to the quality and value of the work we provide to our customers.

In 2017, American Mechanical Services became a 100% employee owned (ESOP) construction company specializing in high-quality HVAC maintenance and services work on mechanical building systems and in complex construction and repair projects involving the renovation and retrofitting of older and occupied structures, both public and private.

In addition to competitive compensation and benefits, AMS offers an ESOP (Employee Stock Ownership Plan), which is a Company provided profit sharing retirement plan that lets you share in the results of the Company.

As owners, we have a stake in the future success of the company. Employees feel more of a connection to our business. We believe in a culture of trust and mutual respect and taking care of our employee-owners so they can focus on their best work and a balanced life.

We provide the highest levels of productivity with exceptional customer service taking pride in keeping customers for life.
