Air Conditioner For Garage With No Windows: The Ultimate Cooling Solution

air conditioner for garage with no windows

Looking to cool down your garage but don’t have any windows? Don’t worry, there are still options available for you to beat the heat and create a comfortable environment. In this article, I’ll be discussing air conditioners specifically designed for garages with no windows.

When it comes to choosing an air conditioner for a windowless garage, one of the most popular options is a portable air conditioner. These units are versatile and easy to install, making them a great choice for garages without windows. Portable air conditioners work by extracting warm air from the room and venting it through a flexible exhaust hose. This hose can be directed towards an existing vent or simply placed outside through an opening in the wall or door.

Air Conditioner For Garage With No Windows

When it comes to finding the perfect air conditioner for a garage with no windows, there are a few factors to consider. Let’s dive into what you need to know in order to make an informed decision.

Factors to Consider

  1. Garage Size: The first thing you’ll want to take into account is the size of your garage. Measure the dimensions of the space so that you can choose an air conditioner with sufficient cooling capacity.
  2. Insulation: Check if your garage has proper insulation. Good insulation helps retain cool air and prevents heat from seeping in, which can impact the overall effectiveness of your air conditioning unit.
  3. Ventilation Options: Since you mentioned that your garage doesn’t have any windows, it’s crucial to explore alternative ventilation options. Look for air conditioners that feature exhaust hoses or can be connected to existing ductwork for proper airflow.

Cooling Capacity Requirements

Determining the appropriate cooling capacity for your garage is essential for optimal comfort and energy efficiency. A general rule of thumb is that a well-insulated space requires around 20 BTUs (British Thermal Units) per square foot (0.09 sq meters) of area.

For example, if your garage measures 200 square feet (18.58 sq meters), you would need an air conditioner with a cooling capacity of at least 4,000 BTUs (200 sq ft x 20 BTUs/sq ft = 4,000 BTUs).

Keep in mind that other factors such as extreme temperatures or excessive heat-generating equipment may require additional cooling power.

Energy Efficiency Ratings

Energy efficiency plays a significant role not only in reducing electricity bills but also in minimizing environmental impact. When selecting an air conditioner, look for models with high Energy Efficiency Ratio (EER) ratings.

The EER rating indicates how efficiently an air conditioner converts electrical energy into cooling power. Higher EER ratings mean more energy savings in the long run.


Determining The Size And Capacity Needed

When it comes to finding the right air conditioner for a garage with no windows, one of the crucial factors to consider is the size and capacity. Determining the appropriate size will ensure that your garage stays cool and comfortable without wasting energy or overspending on an unnecessarily large unit. Here are a few steps to help you determine the size and capacity needed for your specific garage:

  1. Measure the Square Footage: Start by measuring the square footage of your garage. This can be done by multiplying the length and width of the space. For instance, if your garage measures 20 feet long by 15 feet wide, then its square footage would be 300 square feet.
  2. Consider Insulation: Take into account the level of insulation in your garage. If it’s well-insulated with good sealing, it may require less cooling power compared to a poorly insulated space. Keep in mind that garages typically have less insulation than other areas of your home.
  3. Calculate BTU Requirements: Once you have determined the square footage and considered insulation, you can calculate the British Thermal Units (BTUs) required for effective cooling. BTUs measure how much heat an air conditioner can remove from a room per hour. As a general rule of thumb, every square foot requires around 20-25 BTUs for efficient cooling.

Here’s an example table showcasing approximate BTU requirements based on different garage sizes:

Garage Size (Square Footage) Recommended BTUs
Up to 200 sq ft 4,000 – 6,000
200-400 sq ft 6,000 – 8,000
400-600 sq ft 8,000 – 10,000
600-800 sq ft 10,000 – 12,000

Remember that these are just general guidelines and other factors like climate, garage door insulation, and the number of people using the space may influence your final decision.

By taking into account the square footage of your garage and considering its insulation level, you can determine the appropriate size and capacity for an air conditioner that will effectively cool your garage with no windows.
