Thru-the-Wall Air Conditioners
Stay Cool with Efficient
Space-Saving Thru-the-Wall Air Conditioners
A Thru-the-Wall Air Conditioner is a permanent cooling solution installed directly into an exterior wall using a specially designed wall sleeve. Unlike traditional window air conditioners, these units preserve your window space, provide a cleaner appearance, improve insulation, and deliver reliable cooling for years.
Whether you’re upgrading an apartment, condo, home, office, or commercial property, thru-the-wall AC units offer an excellent balance of performance, energy efficiency, and convenience.
At Cool Air Inc. Manhattan, we help customers choose the right thru-the-wall air conditioner and provide professional installation, replacement, and maintenance services throughout New York City.
What Is a Thru-the-Wall Air Conditioner?
A thru-the-wall air conditioner (also called an in-wall air conditioner or wall AC unit) is a self-contained cooling system permanently installed inside an exterior wall rather than a window. The unit sits securely inside a metal wall sleeve, allowing it to cool your room efficiently while maintaining a sleek and finished appearance.
Because these air conditioners don’t occupy window space, they are ideal for apartments, condominiums, hotels, offices, and homes where preserving natural light and outdoor views is important.
Unlike window units that are often removed seasonally, thru-the-wall ACs are designed for year-round installation and long-term durability.
How Does a Thru-the-Wall Air Conditioner Work?
A thru-the-wall air conditioner works similarly to a traditional window AC but is permanently mounted within an exterior wall.
The indoor section pulls warm air from the room and passes it over the evaporator coil, where heat is removed. The cooled air is then circulated back into the room, while the heat is transferred outside through the condenser located at the rear of the unit.
The wall sleeve provides structural support, proper ventilation, weather protection, and helps improve energy efficiency by reducing unwanted air leakage.
Benefits of Thru-the-Wall Air Conditioners
Save Valuable Window Space
Since the unit is installed inside the wall, your windows remain completely unobstructed, allowing more natural light and better outdoor views.
Permanent Installation
Designed for long-term use, these units remain securely installed year-round without the need for seasonal removal.
Improved Energy Efficiency
The permanent wall installation reduces drafts and air leakage, helping maintain indoor temperatures more efficiently.
Cleaner Exterior Appearance
A thru-the-wall installation creates a neat, built-in look that blends seamlessly with your home’s design.
Better Security
Unlike window AC units, wall-mounted systems are much more difficult to remove from the outside, providing added security.
Quiet Operation
Many modern wall air conditioners feature advanced compressors and fan systems that operate more quietly than standard window units.
Consistent Cooling
These systems deliver reliable, even cooling throughout the room and are available in multiple BTU capacities to suit different room sizes.
Heating Options Available
Many models include electric heat or heat pump functionality, providing both cooling and supplemental heating throughout the year.

Choosing the Right BTU Size
Selecting the correct BTU capacity is essential for efficient cooling.
| Room Size | Recommended BTU |
| Up to 350 sq. ft. | 8,000 BTU |
| 350–550 sq. ft. | 10,000–12,000 BTU |
| 550–1,000 sq. ft. | 14,000–18,000 BTU |
| 1,000–1,500 sq. ft. | 20,000–24,000 BTU |
Choosing the right size helps improve comfort, reduce energy consumption, and extend the lifespan of your air conditioner.
