Portable AC

As the summer months are nearing, the need for reliable air conditioning becomes more pressing. While central air conditioning systems are ideal, they can be expensive to install and maintain. 

Portable AC systems offer a cost-effective alternative, providing adequate cooling for almost any space. However, with many available options, choosing the best mobile AC system for your needs can be challenging. 

Here, we’ll share five tips to help you select the best portable AC rental system available:

1. Think About the Size of the Space You Need to Cool

The first and perhaps most crucial consideration when choosing a portable AC system is the size of the space you need to cool. Selecting a unit with enough cooling capacity is essential to keep your room comfortable. Portable AC systems are measured in British Thermal Units (BTUs), which indicate how much heat the system can remove from the air in an hour. The higher the BTU rating, the larger the room the system can cool. For example, a 10,000 BTU portable AC system can cool a room of up to 450 square feet, while a 14,000 BTU system can cool up to 700 square feet.

2. Look for Energy-Efficient Models

Portable AC systems can be energy-intensive, leading to higher electricity bills. To mitigate this, look for energy-efficient models with an Energy Star certification. Energy Star-certified portable AC systems use up to 10% less energy than standard models, which can save you money in the long run. Additionally, many utility companies offer rebates or incentives for purchasing energy-efficient appliances, which can further reduce the cost of your portable AC system.

3. Consider the Noise Level

Portable AC systems can be noisy, which can be problematic if you intend to use them in a bedroom or other quiet space. Look for AC models with a low decibel rating – ideally, less than 50 dB – to ensure the unit won’t disturb your sleep or activities. Additionally, some models have a “quiet mode” that minimises the noise level further, making them ideal for use in libraries or other areas where silence is essential.

4. Choose a Model With the Right Features

Portable AC systems have many features, from basic temperature controls to advanced functions like dehumidification and air purification. Consider the most important features and choose a model that meets those needs. For example, if you live in a humid climate, a model with a built-in dehumidifier can help reduce excess moisture from the air, making your space more comfortable. Additionally, some models have a remote control or smartphone app, which allows you to easily adjust the temperature as well as other settings from anywhere in the room.

5. Consider Renting a Portable AC System

If you only need a portable AC system for a short period – for instance, during a heatwave or while your central air conditioning system is being repaired – it may be more cost-effective to rent than purchase a unit. Portable AC rental companies offer various models, from basic units to high-end models with advanced features. Renting a portable air conditioner can save you money upfront and ensure you have access to reliable cooling when you need it most.


Choosing the best portable AC rental system requires careful consideration of your needs and preferences. By considering such factors as the size of your space, energy efficiency, noise level, and features, you can select a model that suits your needs and budget. 

Additionally, if you only need a portable AC system temporarily, consider renting rather than purchasing a unit. With these tips in mind, you can stay cool and comfortable all summer.
