100 Years of Trusted Plumbing Services

Central Mechanical Services: 1909

Founded in 1909 by the Lightness Family, Central Mechanical has been a cornerstone of quality plumbing services for over a century. Robert Lightness led the company until 1981, instilling a tradition of excellence passed through generations.

From Army Service to Plumbing Service: William Ash

William Ash, a U.S. Army veteran, started his plumbing apprenticeship under the Lightness family in 1957. His military background instilled honor, pride, and commitment, values he carried into his career. William eventually took over the company and ran it until 2002, when his son Kris Ash succeeded him.

Kris Follows in His Father's Footsteps

Growing up in the industry, Kris acquired deep insights into plumbing, hydronics, and boilers. Working in the field for 15 years, Kris gained a unique understanding of customer needs before becoming the project manager and estimator.

The Next Generation: Steven Ash

In 2002, Kris's son Steven began his plumbing apprenticeship. Steven has since earned multiple certifications, including journeyman plumber, medical gas, and others.

Our passion for quality and innovation grows every day. We integrate cutting-edge technology while preserving old-time craftsmanship. In 2009, we celebrated our 100th anniversary, and we look forward to serving our community for another 100 years.

We have been so happy with Central Mechanical Services. They repaired a valve for our bathtub, replaced our water heater and serviced our HVAC. They are quick to diagnose and fix any problems, they are very professional and friendly. Great experience!

Amazing, fast service! Will absolutely use in the future!

— Ali D.

Herb came out and worked on our A/C. He was super friendly and explained what he was doing and what maintenance steps I should take in the future to prevent more problems. I don’t know how much they charge because my home warranty paid for it. Definitely recommend!
