JMB, LLC was a lifesaver. Very professional and caring. My A/C went out on Sunday and he was there first thing Monday morning to assess and fix the problem. If you are looking for a trustworthy, dependable and caring company, I would highly recommend JMB for everyone’s A/C and heating needs.

Slidell, LA
I’m always looking for people who are trustworthy, honest and who have integrity. When I called JMB, I felt those things immediately. They came to my house within two hours and had both of my A/C units up and running in less than an hour. He changed my A/C unit parts, gave me advice, and also helped me find a daycare for my little one! I will forever be in his debt, but do yourself a favor – stop reading this and call him. Make sure to tell him Ms. Gant with the three dogs sent you – you won’t regret it!

I cannot say enough good things about JMB, LLC. When my air conditioning went out on a Saturday evening, I was dreading the long wait for a repair. To my surprise, Josh answered my call promptly and even agreed to come out on a Sunday morning at 7 A.M.! They were extremely professional, knowledgable and efficient. Not only did he fix the issue quickly, but he was also honest and upfront about the problem. I would absolutely recommend JMB, LLC. to anyone in need of air conditioning repair.
