Providing Comfort To Charlotte Since 1946

J. L. Patterson, Sr. started his company in 1946. Originally a coal and oil company, Patterson served a thriving Charlotte area. In 1951 after serving during WWII and graduating from the Citadel, J. L. Patterson, Jr. joined the family company. The 1960s saw major changes in the company as Patterson, Jr. moved the company toward commercial and residential heating and air conditioning sales and installations. 

Dodson Patterson went to work for the company part-time in 1970 at the age of 16. He worked after school and on summer breaks through high school and college until he joined the company full-time in 1977. Working as a service mechanic, residential installation mechanic, and service manager, he eventually established the residential installation department. With only 3 installers he reached $800,000 in sales in 1991, making Patterson Heating and Air Conditioning a major force in residential HVAC sales. In 1992 Dodson moved to the commercial department to estimate and concentrate on managing the company. Since 1990 Patterson has grown from 13 to 50 employees. Patterson today proudly serves Charlotte and the surrounding areas from Mooresville to Rock Hill, Concord to Gastonia for quality commercial and residential heating and air conditioning systems, installation, and maintenance. 

At Patterson, we firmly believe that a company is only as good as the people that work there. We have been blessed with employees who have been a part of the company for many years. There are too many to list, but this shows the strong commitment we have to our employees and to the company. We have found that this philosophy has been an asset to our customers.
