Evaporative or Reverse Cycle Air Conditioning ... which is best?

Posted on Wednesday, October 19, 2016

Are you trying to make the decision between evaporative cooling and reverse cycle air conditioning and not sure which will be best for you?

It’s a big financial decision so you’ll want to get it right, so let’s take a look at both systems which may help you to decide.

Starting with the very basic differences evaporative systems cool only where as reverse cycle will both heat and cool. However you can combine gas ducted heating with evaporative cooling to warm you home which will give you the best of both worlds.

Evaporative cooling system works by drawing the warm air through water soaked pads thus cooling the air. This method works particularly well in drier climates like Western Australian and South Australia.

As they only require power to run the pump and a fan their running costs can be the equivalent as running a light globe. They are by far a less complex system to build and therefore cheaper to buy. The average purchase price and installation cost is roughly half that of a reverse cycle unit. In addition they are easy to maintain and repair and far more environmentally friendlier.

Reverse cycle air conditioning cools or heats the air inside the home and then recycles the air inside the house through a filter called the return air vent. For efficiency it’s best to keep all your external windows and door closed, that way you are not having to cool down or heat up air from outside.
With evaporative cooling you need to leave a window or screen door open to expel the warm air from the home and prevent a build up of moisture.

Certainly there are those who feel the constantly changing air is a good thing while others who suffer from hay fever and allergies might feel that recycling filtered air is better.

Reverse Cycle air conditioning work well in both dry and humid conditions. While they cost more purchase and install they do offer the convenience of both heating and cooling from one unit. It also means just one lot ductwork and grills. Another advantage of reverse cycle is that you can zone parts of the home so that you only cool or heat the parts you are using at the time.

The most important thing to remember is whichever you decide on, invest in a quality brand that is backed with a reputable manufactures guarantee. If you would like to know more check out our website or drop into a store and talk to one of the home climate solutions experts.
