A family-run HVAC company that has been part of the Hattiesburg community for nearly five decades.
Oak Grove Heating & Air Conditioning was founded in 1978 with a simple commitment: provide honest, reliable HVAC service to our Hattiesburg neighbors. What started as a small operation on Oak Grove Road has grown into one of the Pine Belt's most respected heating and cooling companies -- all while staying true to the values we were built on.
For 48 years, we've been the company that Hattiesburg families call when their AC quits in July or their furnace won't light on a cold December night. We've installed systems in new construction, replaced aging equipment in homes that have been in families for generations, and maintained the comfort of businesses across the region.
Today, under the leadership of President Dusty Walker, Oak Grove Heating & Air continues to combine old-school integrity with modern HVAC technology. We invest in ongoing training so our technicians stay current with the latest equipment and efficiency standards, but we never lose sight of what matters most: treating every customer like a neighbor.
Nearly five decades of growth, service, and community trust.
