Are you doing an HVAC project?
Modernize can pair you with three to four pros in your area, so you can compare options and save time and money.
Homeowners know that cooling the home can be a costly problem, so the key to beating the heat is finding an efficient cooling solution that won’t break the bank. A popular option for homes without central air conditioning are window AC units. As you shop, the cost of window AC units will be top of mind and will heavily influence your decision.
Cost factors for window AC units depend on the unit’s size and its compatibility with various window types. We’ll take a look at different factors affecting how each window unit operates and what it costs so you have all the info you need before making a purchase.
The Price Range of Window AC Units
The cost of window AC units varies based on a number of factors including the brand, cooling capacity, energy efficiency and a few other additional features.
On average, window AC units start around $150 and can go up to $800 or more for high-end models. Budget options are plentiful for basic models with lower BTU (British Thermal Units) ratings. However, as the BTU rating and energy efficiency increase, the cost of the unit also goes up.
Additional features might include smart home capabilities or heating features. These units will invariably cost more, but their ease of use could make the higher price point worth it.
Still, using a window AC unit to cool one particular room in your home remains a budget-friendly option over the alternative of installing central AC in your home. Therefore, as you shop, consider how many units you’ll need and how much space you plan to cool in your home with each unit you purchase.
Installing your window AC unit is typically a simple job you can do yourself, but if you need help, or have a specialty unit or window requiring a professional, you might need to hire someone. It can cost anywhere from $60 to $300 to have one of these units professionally installed. Keep that cost in mind as you shop for various units that might require this additional fee.
You can save some money by installing an energy efficient window AC unit when you claim various government rebates aimed at heating and cooling homes. Find out if you qualify by going over our HVAC resources.
Window AC Unit Sizes: BTU and Price Chart
When choosing a window AC unit, it’s crucial to select the right size for the room you are targeting to ensure optimal cooling efficiency. BTU is a measurement for the unit’s cooling capacity, and the higher the BTU rating, the larger the area it can accommodate. This chart shows the BTU rating and the square footage it can handle as well as a rough price estimate for units of these ratings. You’ll notice that large window AC units will cost more than small window AC units, in general.
| BTU Rating | Price Range | Room Size (Approx.) |
|---|---|---|
| 5,000–8,000 | $150–$350 | 100–350 sq. ft. |
| 8,000–12,000 | $350–$600 | 350–550 sq. ft. |
| 12,000–20,000 | $600–$800+ | 550–1,200 sq. ft. |

Finding the Right Fit for Your Window
Window AC units work by sensing warm air in a room, pulling it into the unit and across cooling coils before releasing the air back into the room. They are generally considered more efficient than standalone units which don’t need to be mounted in a window. Because window AC units must be mounted this way, you’ll want to make sure you get one that fits your particular window.

The dimensions of each unit will vary based on the brand and model, but generally, most window AC units are designed to fit standard-sized windows. Before making a purchase, measure the height, width, and depth of your window to ensure the AC unit will fit snugly and securely.
Window AC Units for Small Windows
For small windows, compact window AC units are the ideal solution to beat the heat without occupying too much space. These units typically range from 5,000 to 6,500 BTU (British Thermal Units), efficiently cooling spaces up to 250 square feet. Their smaller size ensures they fit snugly in limited spaces, making them perfect for single rooms, small apartments, or office spaces.
Despite their compact dimensions, these AC units often come packed with features such as adjustable temperature settings, energy-saving modes, and easy-to-clean filters, ensuring a blend of convenience, efficiency, and performance. When shopping for a window AC for a small window, it’s important to measure the window dimensions accurately to ensure a perfect fit and optimal cooling efficiency.
Window AC Units for Medium Windows
Medium-sized window AC units are designed to strike a balance between cooling efficiency and space utilization, making them suitable for rooms ranging from 250 to 500 square feet. With a capacity of around 7,000 to 8,000 BTU, these air conditioners can effectively cool larger bedrooms, small living rooms, or mid-sized office spaces. They often feature a variety of settings including fan speed adjustments, temperature control, and sometimes remote control operation for added convenience.
Additionally, many models are designed with energy efficiency in mind, sporting Energy Star ratings that can help reduce electricity bills during the hot summer months. Installation is straightforward, but ensuring the window dimensions align with the AC unit’s requirements is key for an effective setup.
Window AC Units for Large Windows
For large windows and spaces, window AC units with capacities ranging from 10,000 to 12,500 BTU are the go-to choice. These powerful units can cool areas up to 650 square feet, making them ideal for large living rooms, spacious offices, or entire floor cooling in smaller homes. Despite their robust cooling capabilities, these AC units are designed with efficiency and user-friendliness in mind, featuring programmable timers, digital displays, and energy-saving modes. Some models even offer smart technology integration, allowing for control via smartphone apps.
While these units are larger and require more space for installation, their ability to deliver consistent, powerful cooling across larger areas makes them an invaluable asset during peak summer months. As with all window AC installations, verifying that the unit fits the window size and support requirements is crucial for safety and performance.
Window AC Units for Different Window Types
Most AC units are designed to fit in different types of windows including standard single or double-hung windows, but specialty windows might need a closer look. An awning window, which hinges at the top and opens outward, won’t work with these types of units, for example. And irregularly shaped windows might need the attention of an HVAC pro to address.
Casement windows will require a special window unit which can accommodate this style. Casement windows hinge on one side and open like a door, while standard AC units are designed to install vertically.
Sliding windows open from side to side and a special AC unit will fit horizontally with adjustable panels that will keep the unit securely in place.
Starting Your Hunt
Understanding the cost factors, available sizes, and compatibility with different window styles will help as you begin shopping for your new window AC unit. Be sure to carefully consider the needs for your particular window as well as the size of the room you’re cooling. And don’t forget to factor the cost of installation into your budget should you need to hire a professional.
