Choosing the Right Window Heat Pump

Type of Heat Pump

Window heat pump or wall mount is the first thing the buyer should consider when purchasing a heat pump for their home. Depending on where you live, how long you plan to stay there, and what room you’d like to install it, this answer will be different for everyone.

Heat pumps are ideal for apartments because they can be installed and uninstalled at any time. They are also great for any room with a standard window. Window pumps are convenient for people who would like to avoid difficult installation.

Wall mount heat pumps are another option. The wall mount heat pump is going to require possibly expensive installation. That being said, they are just as powerful as heat pumps. Wall mount heat pumps are not portable and not as convenient.

Room Size

The room size is an equally important factor. When choosing the best window heat pump, you will need to be sure the product has enough BTU to effectively heat or cool the entire area. Online calculators can figure out the exact BTU. Here is a great resource to determine the amount of BTU needed for your room size.


All heat pumps are designed to do the same thing. That does not mean they are all created equal.  Window heat pumps come with a variety of functions. These functions vary from product to product. Decide what functions are important to you. A timer or energy saving function is important to many people. This function allows the unit to automatically heat and cool the room while saving on energy costs. Energy saving functions will automatically turn off the unit when the room reaches the set temperature.

Another function that needs to be considered is heating and cooling. Almost every window heat pump has an air conditioner function. Most of them have heat as well. If you only need a heat pump for air conditioning that can be available. Shop for cooling only units and you may save money and energy.


Everyone has a budget, low or high. Review your budget carefully and account for any costs that may be added if the unit needs professional installation. Heat pumps come in a large range of prices and they can fit into almost any budget. Price is an important detail in deciding which heat pump is right for your home.

Measure your window and carefully read the instructions of your new window heat pump. The instructions should tell you if your window is the correct size. Mark the center of your window with a pencil.

2. Prepare the Window Heat Pump

Take your heat pump out of the package. Be sure to check it thoroughly to ensure there is no damage on the unit. The heat pump will most likely have adjustable side panels. They might slide out or be attachable. According to your window measurements, secure the adjustable panels with screws to fit the window size.

3. Insert Heat Pump into Window

With the help of a friend, lift the window heat pump into the window, angling the back outside. There should be a ridge in your unit for the window to close on securely. Be sure to keep the power cord pulled inside. The window should hold your unit in place temporarily.

4. Secure the Heat Pump

The next step can be done with a drill or screwdriver. Pull the adjustable panels out as far as they will go and insert the included screws. The unit should already have holes where the screws go.
