Are Portable Air Conditioners Worth It? Weighing the Pros & Cons

by Preferred Climate Solutions Portable Cooling and Heating Equipment Rentals

As summer heating continues to reach scorching new highs, more and more people are looking for ways to cool their homes efficiently and affordably. Traditional window air conditioning units can be expensive, difficult to install, and aesthetically unappealing. This has led many homeowners and renters to consider portable air conditioners as an alternative. But are portable air conditioners really a worthwhile investment? In this blog post, we'll examine the pros and cons of portable air conditioner rentals to help you decide if they are suitable for your cooling needs.

Advantages of Portable Air Conditioners


One of the most significant advantages of a portable air conditioner is flexibility. Unlike traditional window units, portable ACs have wheels and are not permanently installed. This means you can quickly move them between rooms or even buildings as needed. So if you want to cool your bedroom at night but your living room during the day, no problem! With a portable air conditioner rental, you can target the room you occupy, maximizing efficiency.

Portable air conditioners are also great for supplemental cooling. You can use them to provide extra cooling power to rooms that your central air doesn't adequately reach. The flexibility of portable units makes them ideal for adaptable cooling requirements.

No Permanent Installation

Installing a window AC unit often requires heavy lifting, special tools, and drilling into your window frame. But portable air conditioners don't require any permanent installation. All you need to do is roll the unit into position, extend the exhaust hose out of a window, and plug it in. The entire setup can be done in minutes, even by one person.

This makes portable ACs ideal for renters who can't make permanent modifications. Renters can wheel the portable unit between apartments. Homeowners may also prefer the simplicity of a portable AC versus permanently installing window units. The convenience of fast setup and takedown is a significant perk of portable air conditioner rentals.

Better Insulation

Unlike window ACs that leave gaps around your window, portable air conditioners fully seal when vented outside. This results in better insulation and less strain on your HVAC system. Portable units preserve the integrity of your home's insulation for more efficient and economical cooling.

Added Features

Many portable air conditioners come with bonus features like humidifiers, air purifiers, and fans. So, in addition to cooling, they can also dehumidify and improve air quality. Some units even have innovative features like Wi-Fi connectivity that allows you to control the AC from your phone. So you get added functionality beyond just the core cooling with many portable ACs.

Small Size

Portable air conditioners are relatively compact. They easily fit in corners or against walls, taking up less interior space than window units. Many portable ACs are roughly the size of a large suitcase on wheels. The small footprint helps conserve precious floor space in your rooms.

Disadvantages of Portable Air Conditioners

Limited Power

A drawback of portable air conditioners is that they have less cooling power than permanently installed units. The typical portable AC has a cooling capacity of around 10,000 BTUs. Window air conditioners often range from 6,000 to 25,000 BTUs. Central air systems have cooling power from 18,000 to 60,000 BTUs.

So, portable units work best for spot-cooling single rooms up to 450 square feet. They may need help to cool large spaces. Larger homes may require multiple portable ACs to maintain desired temperatures. This can diminish the cost-effectiveness compared to more robust central or window air conditioners. But for small to medium rooms, their cooling capacity is usually sufficient.

Noisy Operation

Portable air conditioners require venting hot air outside, which necessitates noisy fans. The constant droning can make it difficult to sleep or work. Some portable ACs are quieter than others, so make sure to research noise levels if this is a concern. Adding sound dampening around the unit or only operating it intermittently can help mitigate the noise.


Portable ACs require draining condensed water in order to operate. Some units have self-evaporating technology, but most need to be drained manually. You'll have to remember to empty the reservoir a few times per day or connect the unit to constant drainage. Failing to drain water will cause the AC to shut off to prevent leaks. Maintenance needs vary by model but are typically more involved than set-and-forget window ACs.

High Upfront Cost

Purchasing a portable air conditioner costs $300-$600 upfront, depending on features and capacity. Larger units with greater cooling power can cost even more. That's a significant one-time investment that may give some buyers pause. However, the long-term savings and convenience may offset the initial sticker shock for many homeowners. Renting eliminates the high upfront cost but results in recurring fees.


The way portable air conditioners are vented outside makes them inherently less efficient than single-hose window units. They require more electricity to achieve the same amount of cooling. Operating costs for portable ACs are estimated to be 30-50% higher. So you'll pay more in utility bills compared to using a window AC unit. However, zone cooling only occupied spaces helps trim costs. But portability comes at the expense of efficiency.


Portable air conditioners offer flexible spot cooling that traditional air conditioners can't match. But they also have downsides like high operating costs, noise, and limited power. Overall, portable ACs are best suited to small urban apartments, rented spaces, or supplemental cooling needs. They offer moderate cooling capacity in a portable package. Just don't expect the power of centralized air. Additionally, considering options like Preferred Climate Solutions can enhance your cooling experience, providing efficient and effective solutions tailored to your specific needs.

If you are considering getting a portable air conditioner this summer, carefully weigh the pros and cons presented in this article. Analyze your specific cooling needs and house layout to determine if a portable AC is suitable. Also, research the noise, maintenance, and efficiency ratings before selecting a particular unit. A portable air conditioner rental lets you test one out before fully committing.
