Hi Gary: Somehow I just got this. I really sorry if this has been sitting here since 2012 without me answering you. I have to get up to 10-12 thousand feet in the Texas heat, and then the cockpit cools off nicely in the summer. Mind you, it never gets cold, but it's not uncomfortable in the summer, especially when I put up the plastic tinting where the sun is coming in. I do have to watch me feet when flying. For long flights I'll take off my shoe's and if I stretch out and my toes touch the firewall, they get hot very fast. That's about it. I have one of those cockpit avionics ports going to the avionics stacks, and the other port venting to the back of the instrument panel. I have good airflow through the vents on the floor, and very good airflow through the overheads. I did have to change the hoses up there though, as when I purchased it, those didn't work very well at all. I think they were the original hoses that came from the factory. Anything other questions, let me know,
