Portable AC rentals are a great option for people who want to be able to cool their homes or offices without having to install a central air system. They are easy to move from room to room, and they can be used to cool off a room when you need it.

A portable AC  is a small, self-contained unit that can be placed anywhere in a room or office. It has a built-in fan and expels hot air through a duct to a window, where it is vented to the outside.

Before you rent a portable air conditioner, you should know a few basic things about it first, like what temperature to set it to. Here, London Climate Hire shares information about this:

What Temperature Should You Set Your Portable Air Conditioner On

If you’re like most people, you probably don’t give much thought to what temperature you should set your portable air conditioner on. After all, isn’t it only a matter of turning it down as low as it will go and enjoying the cool air?

Actually, there is a bit more to it than that. While it’s true that you’ll enjoy the coolest air if you set your unit to the lowest temperature possible, there are a few things you should keep in mind.

First, remember that your air conditioner is working hard to cool the air in your room. If you set the temperature a little too low, it will have to work harder and run for a longer period for you to achieve the desired temperature. This can cause the unit to overheat and shut off, leaving you with a hot, stuffy room.

Second, the temperature you set your air conditioner at will affect how much humidity is in the air. The lower the temperature, the less humidity there will be. This can be a good thing if you’re trying to combat excessive moisture in the air, but it can also make the air feel uncomfortably dry.

So what’s the best temperature to set your portable air conditioner at? A good rule of thumb here is to set it to a temperature that is about 10 degrees cooler than the temperature outside. This will give you a comfortable, cool environment without putting too much strain on your unit.

How to Increase Portable Air Conditioner Efficiency

As the weather gets hotter, many start to think about how they can improve the efficiency of their portable air conditioners. Here are a few tips from our HVAC experts to help you get the most out of your unit:

  1. Make sure that the air conditioner is properly sized for the room. An air conditioner that is too big for the space will not be as effective as one that is properly sized.
  2. Place the air conditioner in the coolest part of the room. This will help it to work more efficiently.
  3. Close the doors and windows in the room to keep the cool air in.
  4. Use a fan to help circulate the air.
  5. Clean the air filter regularly. A dirty air filter makes the air conditioner work harder and reduces efficiency.

By following these tips, you can help to improve the efficiency of your portable air conditioner and keep your home or workspace cool and comfortable all summer long.


To get the most out of your portable air conditioner, set it to a temperature that is 10 degrees cooler than the temperature outside. This will help your unit run more efficiently and prevent it from overworking. Also, follow the tips we shared to help improve your portable AC rental’s efficiency.
