I rarely take the time to leave reviews but this is one of the top two or three companies I have ever worked with. Throughout the process of picking out an AC unit to getting it delivered, I spoke with several people that were all stellar. The technical team helped me confirm all the details for my electrical system and when the time came to buy their sales/admin team were amazing in working with me. Shout out to Mary specifically, she treated me like I was a business placing a bulk order for 100 air conditioners when I was just buying one system. It's one of the rare cases where I have zero anxiety over working with their customer service if anything ever did go wrong. I can't wait to get the X3 installed and use it!!!


I recently purchased an X3 air conditioning unit for my campervan, and I am absolutely thrilled with the product and the customer service I received. From the moment I reached out with my initial questions, their team was attentive, knowledgeable, and incredibly helpful. The installation process was a breeze, and the performance of the unit has far exceeded my expectations. The fact that they have actual people to answer your questions and provide support makes all the difference. I highly recommend Nomadic Cooling to anyone looking to build a campervan!

I got my AC up and running today after a very long delay. My fault…life got in the way. Even though technically my warranty was expired before I even got it installed, the wonderful folks at nomadic went above and beyond to help me with the issues with was experiencing. The new AC works great. Super low profile on the roof and a very thin inside control panel which is especially important in a van! I’ll be taking my first road trip this week and I couldn’t be happier. Trust these folks…they make a good product and really stand behind what they sell.
