After a tornado damaged this business last year, a good majority of the building needed to be reconstructed, including the HVAC system.

This is 2/4 of the systems we hoisted up on the side. These systems will ensure the inside temperature is perfect when they’re open again for operation!

Good luck with the grand reopening! 🫶
