Denver Heating and Cooling: AC Systems Have Surely Come a Long Way


This may surprise you, but air conditioning systems have actually been around for a long time. In fact, attempts at developing cooling technology have been observed as early as 2,000 years ago, more or less. In 2nd century China, there existed manual rotary fans that brought outside air into a room. In 3rd century Rome, ice was supposedly imported from the mountain regions via donkey train to cool an emperor’s garden.

Air conditioning systems have certainly come a long way since those bygone days, but somehow, the same concepts behind them remain to provide thermal comfort indoors. Today, air conditioners installed by Denver heating and cooling companies come in different types and sizes. There are ground units, rooftop air conditioners, even cooling towers, to name a few. There are even air conditioning units that fit inside a window pane resting on the sill.
