H. A. Thompson & Sons

Since 1908, H. A. Thompson & Sons has provided exemplary plumbing, heating and cooling services.  While the company began in Bismarck, ND, they quickly expanded their service area to include all of North Dakota, South Dakota, Minnesota and Montana.  This regional growth brought needed services from trained professionals to a larger number of customers.  As the company has grown, so have the quality and types of available services.  For instance, the company underwent a certification process and began offering Environmental Maintenance Agreements.  This allowed home and building owners to receive regular preventive maintenance and checks on indoor air quality.  Currently, this program serves over 600 commercial properties. 

As Trane certified technicians, they are able to care for current units, as well as, install new ones when needed.  The Trane ‘Comfort Specialist’ designation is bestowed on organizations who have demonstrated a commitment to the highest level of service and the desire to consistently improve their technical knowledge of the heating and cooling industry.  Whether it is a commercial or residential need, the pros at H.A. Thompson & Sons are ready to accommodate any need.  From installation to regular maintenance to repairs when needed, they will keep a home’s air quality clean and comfortable.
