8 fascinating facts about HVAC

If you don’t think there’s anything interesting about heating, ventilation and air conditioning (HVAC), then our eight fascinating facts aim to prove you wrong!

1. The first modern air conditioner wasn’t designed for people’s comfort, but was used in a Brooklyn publishing company to reduce printing quality issues. In 1902 Willis Carrier invented an air-conditioning machine for the Sackett-Wilhelms Lithographing & Publishing Company to maintain low temperature and humidity, which helped stop the paper expand and contracting.

2. Air conditioning is responsible for the ‘summer blockbuster’. In the US, during stifling summer heat, the coolest place to go would often be an air-conditioned cinema. The movie industry took advantage of this by releasing their biggest films in July, a tradition which continues to this day.

3. The world’s first steam-heating system was installed in the home of Governor of the Bank of England John Horley Palmer in 1832 so he could grow grapes even when the ambient temperature was cool.

4. The Romans were the first civilization to use a warm-air heating system.

5. In 1936, Packard became the first car manufacturer to integrate air conditioning in their vehicles.

6. A build-up of just 0.042 inches of dirt on a HVAC coil can reduce efficiency by as much as 21%.

7. More than £1 billion is wasted every year by high-street stores leaving their doors open in winter whilst heating their shops.

8. Using a variable-speed drive in a HVAC system can reduce energy use by as much as 50%.
