Fun HVAC Facts
HVAC systems have come a long way since their invention ages ago. The units have some interesting stories you might want to read while relaxing. Here are some fun facts you probably didn't know about HVAC systems.
- Willis Carrier invented the first contemporary HVAC system in 1902. He intended to help lower the temperatures and humidity for a publishing firm in New York and hoped to protect the papers from expanding and contracting.
