You may have a friend, who knows someone that says it’s a good idea to do something you might not think with your AC. Although it may seem like a good idea at first it may actually end up costing you more energy or even money in the end. Below we have listed the top five myths about how to go about using your machine and what to avoid for maximum efficiency.

Myth #1:  It’s more efficient to leave your portable AC running at a high temperature when you’re not around then it is to turn it off.


That statement is actually false. First off, turning up your AC to a higher temperature while you’re gone will waste energy. Setting your timer for half an hour to an hour before you come home is actually a better idea. It’s always nicer to come home to a place that has been cold for a while, but rather than waste electricity and potentially shorten the life of your machine why not take advantage of its timer? Leaving your unit on essentially causes your compressor to cycle on and off many times just to keep that temperature constant. Leaving it off for extended periods is actually best for your machine.

Myth #2: Your portable AC will perform at its best no matter where you place it or install it.


This statement is also false. Where you place your unit can have a large effect of how efficiently it works within your space. Setting it in direct sunlight will cause your machine to overwork and use more energy. The same goes for placing it close to large electronics that give off heat as well. It’s best to place your unit directly under your window or at least somewhere shaded away from any large electronics.

Myth #3: Maintaining and changing your filter once a month is too often and not necessary.


It all comes down to how often you use your unit. If you use it once or twice a week I don’t see a reason to change your filter once a month. Although, if you use your unit daily. Then doing so may be a good idea. Once your filter starts looking brown and Dusty you should definitely consider making a change very soon. Something as little as a dirty filter can cause your machine to work that much harder and cost you just that little bit more on your utility bill at the end of the month.

Myth #4: “Energy efficient/eco-friendly” are the best portable air conditioner units to buy and will automatically lower my utility bills.


Buying a unit that is energy-efficient will help you save money on your electricity bill at the end of the month but you still need to ensure that it’s installed correctly and securely.( see our article on How to get the best performance from your portable ac. ) At the end of the day you still need to make sure that you buy the best unit for your rooms dimensions. That is the first step on the path of making sure you are reducing any chance of a higher electricity bill at the end of the month.

Myth #5: Turning my thermostat down to an extremely low temperature will help cool my room faster.


In actuality lowering your thermostat to an extremely low temperature too fast will increase humidity. (especially if you live in a humid climate). It’s best to gradually lower the temperature so your unit doesn’t have to work too hard to maintain the temperature on the thermostat. In the end, portable AC units produce heat almost as much as they produce cold. So trying to make it cool too fast will cause it to overwork and to use more energy.
