How To Pick The Right Garage Air Conditioner

Garage Size: 

The first step in choosing an air conditioner for your garage is to measure the size of the space. The cooling capacity of an air conditioner is typically measured in BTUs (British Thermal Units), and you’ll need to select an AC unit with the appropriate BTU rating to effectively cool your garage. As a general rule, you’ll need about 20-25 BTUs per square foot of space. So, for a 400-square-foot garage, you’d require an air conditioner with a cooling capacity of approximately 8,000-10,000 BTUs.

Window or Portable Unit: 

You can choose between window-mounted or portable air conditioning units for your garage. Window units are typically more powerful and efficient but require installation through a window or a dedicated opening in the wall. Portable units are more flexible and don’t require any permanent installation, making them a good option if you need to move the AC to different areas of your garage.

Energy Efficiency: 

Consider the energy efficiency of the air conditioner. Look for models with a high Seasonal Energy Efficiency Ratio (SEER) to ensure that you’re not overspending on electricity. Energy-efficient units not only save you money but are also better for the environment.

Noise Level: 

Some air conditioners can be quite noisy. If you plan to spend time in your garage working, relaxing, or even using it as a home gym, a quieter air conditioner is essential. Check the decibel (dB) rating to ensure it’s not too disruptive.

Maintenance and Installation: 

Think about how easy the unit is to install and maintain. Some units may require professional installation, while others can be set up by DIY enthusiasts. Regular cleaning and maintenance are also essential to ensure the unit operates efficiently.

Dehumidifying Function: 

If your garage tends to get humid, consider an air conditioner with a built-in dehumidifying function. It will help maintain a comfortable and dry environment.

Price and Warranty: 

Set a budget for your garage air conditioner, but remember that quality and features often correlate with price. It’s also a good idea to look for units that come with warranties to protect your investment.

Maintenance Air Filters: 

Ensure the AC unit has easily accessible and replaceable air filters. Keeping these filters clean and changing them regularly improves the air quality and overall efficiency of the air conditioner.


What size of garage air conditioner do I need?

The size of the air conditioner you need depends on the square footage of your garage. As a general rule, you’ll need about 20-25 BTUs per square foot. Measure your garage’s dimensions and choose an air conditioner with the appropriate cooling capacity.

Can I use a window air conditioner in my garage? 

Yes, you can use a window air conditioner in your garage if you have a window or an opening where the unit can be installed. These units are typically more powerful and efficient but require permanent installation.

Are portable air conditioners suitable for garages? 

Portable air conditioners are suitable for garages, especially if you need flexibility in positioning the unit. They do not require permanent installation and are relatively easy to set up.

How do I install a window air conditioner in my garage? 

Installing a window air conditioner in your garage typically involves securing the unit in a window frame or through an opening in the wall. It’s often a DIY project, but if you’re not comfortable with it, consider professional installation.

Are there air conditioners designed specifically for garages? 

While there are no air conditioners exclusively designed for garages, you can use residential units in your garage. Just make sure the unit’s cooling capacity matches your garage size and requirements.

How do I maintain my garage air conditioner? 

Regular maintenance includes cleaning or replacing air filters, cleaning the condenser coils, checking for refrigerant leaks, and ensuring the unit’s drain is clear. Consult the manufacturer’s manual for specific maintenance instructions.
