When it comes to staying cool during the sweltering summer months, portable air conditioners offer a practical solution. However, finding a unit that effectively cools your space without drowning out your favorite TV show or disrupting your work can be challenging.
If you’re seeking a balance between performance and noise levels, this guide will help you navigate the world of portable air conditioners.
Understanding portable air conditioners
Portable air conditioners are gaining popularity due to their convenience and cost-effectiveness compared to permanent air conditioning systems. However, there are important factors to consider before making a purchase.
Here are some key points to keep in mind:
- Convenience: These units can be easily moved from one room to another, making them ideal for renters or those who cannot install permanent systems.
- Cost: Generally, portable air conditioners are more affordable upfront than split systems, but they may incur higher running costs over time.
- Noise Levels: Many models tend to be noisier than their fixed counterparts, which can be a significant drawback during quiet hours.
Why noise matters in air conditioning
The noise produced by an air conditioner can greatly affect your comfort level. High noise levels can be distracting and disruptive, especially in settings where concentration or relaxation is required. Whether you’re working from home, enjoying a movie night, or trying to sleep, the sound of a loud air conditioner can be an unwelcome guest.
Sound is measured in decibels (dB), and understanding this scale can help you choose a quieter model:
- A conversation typically measures around 60 dB.
- A running shower can reach approximately 70 dB.
- Many portable air conditioners operate between 54 dB (quieter) to 69 dB (very noisy) on high speed.
Knowing these comparisons can guide you in selecting a unit that won’t disrupt your environment. If you have specific noise sensitivity or other needs, keep these levels in mind.
Testing for quietness and efficiency
In our recent tests, the CHOICE team assessed various models for their noise levels and cooling efficiency. While some portable air conditioners excelled in being quieter, many fell short in actual cooling performance.
Here are some findings from our tests:
- Several models rated between 57–59 dB, which categorizes them as “quieter” options.
- Unfortunately, the quieter models often had lower cooling effectiveness, meaning they may not meet your cooling needs.
- None of the quieter models received a recommendation due to their overall performance.
“Most portable air conditioners tend to be fairly noisy, regardless of their efficiency and performance,” says CHOICE air conditioning expert Chris Barnes.
Spotlight on quiet models
If noise is a top concern for you, here are some of the quieter portable air conditioners currently available:
Aldi Stirling PA09W1
- Fan noise on high: 54.0 dB (Much quieter)
- Cooling score: 51%
- RRP: $229
- Running costs: $49*
This model is the most affordable and quietest in our tests. However, it ranks low in cooling performance. If you’re looking for a budget-friendly, quiet solution, this might be worth considering.
It’s worth noting that although it is tempting to opt for a low-cost model, it may not provide the cooling relief you desire. Check out the full review of the Aldi Stirling PA09W1 for more insights.
Polocool PQ10C
- Fan noise on high: 57 dB (Quieter)
- Cooling score: 54%
- Price: $829
- Summer running costs: $144
This unit is noted for its quiet operation but struggles with cooling efficiency. It does provide a balance for those who prioritize low noise but may not effectively cool larger spaces.
While it may seem like a good deal for a quiet unit, there are better-performing options available at a similar price point. Read more in our full review of the Polocool PQ10C.
Click CPAC1907-C
- Fan noise on high: 59 dB (Quieter)
- Cooling score: 47%
- RRP: $279
- Running costs: $114
Despite being a quiet option, this air conditioner underperforms in cooling efficiency compared to more affordable models, like the Aldi unit. Additionally, it has a shorter warranty, which may raise concerns about its durability.

Making the right choice for your space
When selecting a portable air conditioner, consider the following factors to ensure you choose the best model for your needs:
- Noise Level: Evaluate how sensitive you are to noise and whether you require a quieter model.
- Cooling Performance: Assess the cooling capabilities to ensure it meets your comfort needs.
- Energy Efficiency: Review the running costs to avoid high energy bills during peak usage.
- Space Requirements: Ensure the unit is suitable for the size of the room where it will be used.
- Warranty: Consider the length and terms of the warranty as an indicator of the manufacturer’s confidence in the product.
Looking for alternatives
If you find that portable air conditioners do not meet your needs or budget, consider alternative cooling solutions:
- Fans: Pedestal and tower fans can provide a cost-effective way to circulate air and create a breeze.
- Evaporative Coolers: These units are efficient in dry climates and can significantly lower temperatures.
- Window Units: If you can install a window unit, they often provide better cooling performance and are quieter than portable models.
