On 5/7/2017 Michelle H. had this to say:
Did all the work on our new home. Dependable, trustworthy, got the job done quickly and correctly. We did a lot of bidding and JAX price was the best around.

On 12/16/2010 Thomas K. had this to say:
I can't say enough about JAX HVAC. Everyone else I called about my furnace just wanted to sell me a new one. Jack told me I did need to replace it, but said he could repair it and it should get me through another winter or two. It was nice to work with someone who treats customers with respect
