About Us

About Dial One Johnson Plumbing, Cooling & Heating

Proudly Serving the Greater Dallas Area

In 1965, Lemuel C. Johnson founded Johnson Plumbing. It was the first plumbing company in Desoto. Johnson Plumbing has grown to become Dial One Johnson Plumbing, Cooling and Heating. The company is now owned and operated by Lemuel’s daughter-in-law, Sherrie Johnson-Hartsock, with his grandson, Daniel Johnson, a third-generation plumber who is also the Service Manager.

It was important to Lemuel that the company was founded on building community and providing great customer service. Our family has done our best to preserve these values. We understand, as the original Mr. Johnson did, that maintaining excellent customer service and building relationships with customers is key to providing great service.

Our family knows the importance of functioning plumbing and HVAC systems and that these systems will not wait until regular business hours to fail. We answer emergency calls 24 hours a day!
