DeHart Plumbing, Heating & Air, Inc.

DeHart Plumbing, Heating & Air, Inc. has kept Central Valley homes comfortable since 1946, making it one of the oldest continuously family-owned HVAC contractors in Modesto. The company holds California license 724566 and Nevada license 0088575, serving Modesto and the surrounding communities alongside a second location in Reno-Sparks. With 4.9 stars across nearly 2,400 customer reviews, the contractor has earned a reputation built on residential and light commercial service throughout both regions.

What distinguishes DeHart from newer competitors is their commitment to backed workmanship. The company offers a 100% satisfaction guarantee alongside an industry-leading 10-year parts and labor warranty on new installations. All service technicians hold NATE certification, ensuring they meet industry standards for HVAC installation and repair. Their Love Club maintenance program provides two annual HVAC tune-ups, annual plumbing inspections, and a lifetime repair warranty for members who maintain continuous enrollment.

Recent customer reviews name specific technicians who handled real problems. Ivan Velasquez repaired two leaking hose bib pipes in a single afternoon, answering every question the homeowner asked. Jonah arrived with ladder and photo documentation to diagnose a non-operating heater, showing the customer exactly what needed repair before providing a fair estimate. Another reviewer specifically credits technician John with identifying an issue other contractors had misdiagnosed, saving them from an unnecessary $12,000 AC replacement.
