Hi Satto,
On # 150 can you make heating and cooling one color and more easy read, it will be on the side of our trucks so needs to be seen and read easily. Perhaps try heating and cooling in all red, then again with heating in red and cooling in blue. The logo will be on a yellow truck, so the top roof somehow needs to be outlined or something so it doesn't blend into the truck to easy. Also, make the entire logo a little wider, I think that will help with making heating and cooling bigger. Thanks!
