VIP Comfort 5 product stars
"In our stadium s VIP lounge, comfort is non-negotiable and the Westinghouse 36,000 BTU Hyper Heat Pump delivers. The ultra-quiet operation keeps conversations crisp, while its even airflow means every seat feels just right. Even during frosty winter games, it holds strong down to 13 F, keeping guests warm without effort. Installation required some planning ductwork, wiring, and thermostat setup but the result blends seamlessly into the lounge s design, making comfort here as premium as the view." M. Gillen - Tuesday, August 12, 2025
