Who keeps turning up the AC?
Let's face it – without our HVAC systems, modern life would be a drag. The ability to cool down by turning a k**b is something our ancestors could have only dreamed of…

Ice power!

Did you know that the first air conditioner’s performance was measured in “Ice Power”?

Ice power was determined by how many blocks of ice it would take to generate the same amount of cooling power.

Before air conditioners were a thing, people used to actually fill their homes with blocks of ice in order to keep cool during the summer!

Homes were also designed with high ceilings, sleeping porches, breezeways, and lots of shadows to beat the heat – thankfully the same effect can now be achieved through everyone's favorite modern invention: central air!

Can’t live without your air conditioner?

You’re not the first one to say that.

Air conditioning actually dates back to prehistory. Ancient Egyptian buildings were known to use many passive air conditioning techniques to keep them cool in the desert heat.

But what is passive air conditioning?

First, let's establish what air conditioning actually is: it's the process of removing heat and controlling the humidity of a space to maintain a more comfortable interior environment.

Passive air conditioning comes in many forms:

-Cross ventilation: allowing air to pass freely through the building by means of two openings on either side of the house
-Stack ventilation: allowing the rising hot air to escape the building through openings in the roof
-Night flushing: keeping the air in a building sealed throughout the day, then allowing new cooler air to flow during the night
-Radiative cooling: designing surfaces of a building such as the roof to better radiate heat outwards, typically during the night
-And many more!

Passive air conditioning involves many feats of physics and engineering, and so does the modern “active” air conditioning that we use today.

So the next time you come inside to a cool room after the summer heat, take a moment to think about the ancient Egyptians and their ingenious ideas :)

If you love your air conditioner, and we all do – then there is one man you should thank in particular.
Willis H. Carrier built the first modern electrical air conditioning unit in 1901.
But you may be surprised why.
At the time, Sackett-Wilhelms Lithographing & Publishing Company had a serious issue on their hands. Temperature fluctuations in the printing rooms were causing their paper to expand and contract, and their drying ink to smudge.

Mr. Carrier installed his AC unit in 1902 to combat these problems, controlling the temperature and humidity of the building – et voila, their issues were solved!

More people started to catch on to the fact that these systems were pretty nifty, and, by 1914, domestic AC units began to really take off!

The rest is history :)

Our HVAC systems truly are unsung heroes.

They keep the summer heat at bay, and keep us warm and toasty during the winter.

But as they say, you don’t know what you’ve got until it's gone!

So here are some tips to make sure you never have to live without it!

-Have your HVAC system serviced at the beginning of each cooling and heating season
-Check your ducts for air leaks
-Keep the area around the outside unit unobstructed by foliage
-Regularly clean the condenser and evaporator coils
-Check the flame in the furnace to ensure that it is a crisp blue color

Let's all take a moment to appreciate the brave HVAC systems who work day and night to keep us comfortable and happy :)
