Taking Care of Hattiesburg’s Heating & Cooling for 32 Years

About Us

Get to Know Jim Smith Services, Inc.

Jim Smith was doing HVAC and refrigeration work for the local Coca-Cola plant when it was bought out. Mr. Jim wanted to do work that truly served Hattiesburg, so in 1994, he founded Jim Smith Services, Inc.. To this day, we’re still a locally owned company with local values.

At 83, Mr. Jim remains a driving force in our company and the Forrest and Lamar County community. He not only runs Jim Smith Services but also serves on the mechanical board for the City of Hattiesburg.

Mr. Jim makes sure Jim Smith Services technicians stay up to date in the HVAC field. He continues to pass on his own wealth of knowledge. He also provides opportunities for technicians to learn about new products and continue their industry education.

Our technicians aren’t just knowledgeable, though. They’re also friendly faces Hattiesburg residents recognize. Since Jim Smith Services is a small company, we’re able to really get to know our customers. This is a point of pride for us. The better we know you and your home comfort needs, the better we can help.

Find Out Why Jim Smith Services Is Hattiesburg’s Favorite HVAC Company

Prompt, Affordable AC Repair, Even in Extreme Heat

Monica Tisack Kathmann

Mr. Jim is honest, prompt, and saved me several times! Of course he had to do attic work in 100 degree weather and didn't complain at all. I was just telling someone that any other company would try to sell me a whole new unit when the fix is relatively small and affordable.

Same-Day AC Drain Repair

Joan

We recently had a leak in the AC drain. Mr Jim and John came out the very morning I called and got us fixed up pronto. Anytime we have a need, they are prompt to respond and we can go about our day. We appreciate y'all so much!

Life-Saving Service

J Keyseear

The good people at Jim Smith literally saved my life. Discovered a carbon minoxide issue with my heat ; they came out the same day and got me fixed up. The only company I called who cared enough to come out that quickly. They treat you like family. Thank you, God Bless you all, especially the receptionist who is wonderful.
