4 Best Quiet Window and Portable Air Conditioners
Noisy air conditioners can make your indoor home or car environment uncomfortable.

Although you can use sound-deadening materials to eliminate noise in your van or home, they are ineffective for air conditioners. Therefore, you need a quiet window and portable air conditioner for a peaceful, relaxed house or car.
The best quiet window and portable air conditioner is the Soleus Air Exclusive Air Conditioner (view it on Amazon). The Soleus Air Exclusive has a 49 decibels (dB) noise level at the highest air CFM. It also has a saddle design that fits perfectly on the window.
In the rest of this article, I’ll discuss the four best quiet window and portable air conditioners. Let’s get started!
Best Quiet Window and Portable Air Conditioners
Here are the best quiet and portable air conditioners available in the market.
1. Soleus Air Exclusive Air Conditioner (Best Overall)
One of the main challenges when looking for a quiet window and portable air conditioner is getting one that doesn’t obscure your view of the outside world. Most window air conditioners are large and might cover the entire window.
The Soleus Air Exclusive is your go-to option if you’re looking for a quiet and portable window air conditioner that doesn’t cover your entire window. This air conditioner has a saddle design that allows you to slide it up and down the window without minimizing or obscuring your view.
The Soleus Air Exclusive also has a noise level of 49 dB at the highest air cubic feet per minute (CFM) of 270. This makes it one of the market’s quietest window and portable air conditioners. You can also set it to the lowest air CFM of 170, which produces 38 dB of noise.
Pros
- Sufficient cooling power. The air conditioner generates 6,000 British Thermal Units (BTU) of cooling power at maximum speed. This power is enough to cool up to 275 square feet (25.54 sq m).
- It’s energy-efficient. With the cost of electricity averaging 14.6 cents per kilowatt-hour (kWh), you need an air conditioner that doesn’t use excessive electricity. The Soleus Air Exclusive has an energy efficiency ratio of 12.1, which is suitable for households. It also has an energy-saving mode.
- Low noise levels. The air conditioner has a maximum of 49 dB noise level. This is suitable for your indoor life.
- Comfort fit. The saddle design enables the air conditioner to fit even on 11-inch (279.4 mm) windows without obstruction.
- Remote-activated. You can regulate the AC from the comfort of your couch using a remote.
Cons
- It’s expensive. The saddle design and energy efficiency make the Soleus air conditioner a bit pricey.
- You might need an extension cord. The power cord is only six feet (1.82 m) long, which might not be long enough for some windows. You can buy an extension cord to solve this problem.
- It’s not a well-known brand. The Soleus Air Exclusive is not famous like TOSOT and Haier. Thus, it might not have the same level of customer support.
2. Shinco Air Conditioner (Best with inbuilt Dehumidifier)
According to Healthline, a dehumidifier makes breathing easier for asthmatic and allergic people. Therefore, apart from creating a conducive indoor temperature, you need a dehumidifier to make your air breathable.
The Shinco air conditioner is one of the best quiet window and portable air conditioners with an inbuilt dehumidifier. This combination saves you the cost of buying a standalone dehumidifier.
The Shinco 8,000 BTU is a quiet AC unit with an easy-to-fit window-mount exhaust kit. It also has an inbuilt dehumidifier that removes up to 40 pints (18.93 liters) of moisture daily. The dehumidifier function can be turned on and off independently from the air conditioner.
