Question #1: How long can you leave your Portable AC on for?


Technically you can leave your AC on all day and all night, although this might not be a good idea for a few reasons. First off, leaving it on constantly is a waste of electricity and will only eat away at your electrical bill every month. Even though most units shut off their AC function once the desired temperature is reached, you’re still making it work at times you probably don’t need it.

For example why would you need your unit running at home while you’re at work? Why not set a timer and have it come on one hour early? That way your place is cool when you arrive, you save electricity, and your unit is only working hard for a few hours as opposed to overworking all day.


Question #2: Why does my Portable Air Conditioner keep shutting off of AC mode every 10 mins?


There are a few possible reasons why this could be happening. One reason could be that your drainage tank has filled and your machine has automatically switched off of warn you about emptying the bucket. Another possible reason is that you haven’t placed your unit in a good place or provided enough room around it to function properly.

This is a similar problem that I’ve had with my first machine. Now not all user manuals tell you this upfront. Some might tell you to make sure your unit is 5 inches or so away from the wall at the back, but they don’t all stress the importance of providing space around the vents on the side (unless you go to the troubleshooting section). On average you should have approximately 1.5 to 2 ft. of space around your unit for the best cooling performance.


Question #3: Where can I buy the best portable air conditioner


I see this question a lot and I used to wonder why I would always see it. There are tons of places online to purchase a portable AC. From,,,, and even I could keep going but the point is this. In most cases unless you live in the United States these websites will not ship to your destination.

For example with Amazon if you visit their “.com” version of the website you will see a large selection of top quality portable air conditioners, but if you go to the “.ca” version of the website you will see a much smaller selection of average portable air conditioners. If you try to purchase from the “.com” site from outside of the US, Amazon will immediately tell you that they do not ship to your location. Now not all “.com” websites are like this but a vast majority of them are which limits foreign countries from gaining access to some of the best units at some of the best prices online.

Now I’m sure if you really search you can find a dealer online that will ship to your country, but in those cases you’re looking at either higher prices or guaranteed shipping charges. Sometimes even both. If you can’t find any online stores that sell the brands you’re looking for you can always try searching for places locally in your town.
