36 Must-Know Air Conditioning & HVAC Statistics (2023)

Can you imagine a world without Air Conditioners & HVAC systems?

Withstanding freezing Winters and sweltering Summers would be almost impossible! Not to mention that department stores and movie rental businesses wouldn’t have that fresh feeling when you walk in the door.

I strongly believe that the more you know, the better, so it’s worth knowing some important statistics about ventilation appliances. My main goal is that you leave this article with a newly-acquired and clearer perspective on the world of HVAC.
