“We recently installed a MaXus Air upgrade in our 2008 Matrix. It has transformed the way we think about using the airplane. Before the MaXus Air installation, I would insist on early morning departures so my passengers and I could be reasonably comfortable. We always flew with the window shades down and often with heat shields blocking the cockpit side windows just to keep cabin temperatures somewhere approaching acceptable. Cabin temperatures even at altitude could easily be uncomfortable on sunny days. The MaXus Air system effectively addresses all the factory deficiencies increasing airflow, cooling capacity, and reducing the distance cooled air travels before entering the cabin. The MaXus Air system adds to the utility of our Matrix by significantly increasing the comfort level of passengers and crew while giving us the confidence to schedule flights on hot summer days. Worth every penny.”
