On December 12, 1953, Mr. Richard F. Armstrong, the founder of Denver Plumbing Company, returned home from serving a tour of duty in Korea representing the 3rd Armored Tank Division of the U.S. Army. Soon, he began an apprenticeship under Mr. Herman Caldwell, who operated the business as Caldwell Electric and Plumbing in Denver, North Carolina. Due to poor health, Mr. Caldwell decided to retire and moved to the Mooresville area leaving Denver without a plumber or an electrician. 


In June of 1957, Richard bought a 1951 used truck and started working under the name Denver Plumbing Company. Richard’s son, Clyde, graduated from college in 1974 and decided to go into business with his father. Richard’s daughter, Lanelle Coffey, joined the business in 1987 after being in the nursing field. Richard continued being active in the plumbing business until 2005.  Clyde and Lanelle continued to grow Denver Plumbing Company into a well-respected local business. 

In 2023, determining that it was time for well-deserved retirement, the Armstrong family sold Denver Plumbing Company to local business owner, Jeff Smiley.  Jeff founded Climatech Heating and Cooling in 1998 and built it into a successful business serving all of the Lake Norman area and surrounding counties.  He and his wife, Cathy, have raised their family here and continue to live in Denver.


The same founding principles continue to this day...integrity, excellent customer service, and commitment to the Lake Norman community.
