The first Dwyer business in the plumbing, heating, and air conditioning trades began in 1922. Since the start-up of the first family-owned and operated company that year, the Dwyer workforce has professionally served hundreds of thousands of residential and commercial customers in Northern Virginia, establishing a tradition of workforce excellence and earning customer trust in the process. Dwyer is proudly independent of all other companies and their trade names; and is an accredited member of the Metropolitan Washington, D.C., Better Business Bureau.
