About DeHart Plumbing, Heating, and Air Inc., Modesto, CA
A Local Tradition Since 1946
In 1946, James Arland DeHart and his sons, Paul and Gary, set out with a simple goal: to help local homeowners with their plumbing and sheet metal needs. What began as a small business has grown into one of the Central Valley’s most trusted names in home comfort. For generations, our neighbors have relied on us for heating, cooling, and plumbing solutions built on honesty, craftsmanship, and care.
