Step by Step Processes for How to Size a Mini Split for a Garage

Step 1: Inspect Your Garage

Start by taking a closer look at your garage. Measure the dimensions of the space using a tape measure, including the length, width, and ceiling height.

Once you have measured your garage’s dimensions, multiply the length by the width to determine its square footage. This number will be used to calculate the BTU (British Thermal Units) needed to heat or cool your garage.

Step 2: Consider the Climate

The climate of your area can impact the size of mini split you need. If you live in a colder area, you may need a larger unit to effectively heat your garage during winter months. Similarly, if you live in a hotter area, a larger unit may be needed for efficient cooling.

To determine how many BTUs your mini split needs, multiply the square footage of your garage by 25. This will give you an approximate number for heating and cooling.

Step 3: Factor in Insulation

If your garage is well-insulated, you may need less BTUs to heat or cool it. On the other hand, if your garage lacks proper insulation, you may need to add 10-20% more BTUs.
