However, all this can be super uncomfortable if your garage has no air conditioning. And this is the case for many houses, especially because many garages do not have ductwork.

If your garage has no ductwork, a proper way to cool the air is to install a mini-split air conditioner.

The big question comes in: are ductless mini-splits good for a garage?

And, what size mini-split is suitable for your garage?

Read on to find all you need to know before installing a mini split in your garage.

Ductless Mini Splits for Garage

There are several choices you could consider to heat and cool your garage. These include garage heaters and, of course, mini splits.

However, just because you can use garage heaters does not mean you should. First, ductless mini-splits are an appealing option for the garage as they do not need ducts. Secondly, they are extremely energy efficient.

You can also mount them high up on the walls. This leaves you with enough space on the floor for whatever activities you need it for.

Can a Ductless Mini Split Cool a Garage?

A ductless mini-split is an excellent cooling option for your garage. They can lower the garage temperatures from 95°F (35°C) to 75°F (24°C).

In the cold winters, temperatures can drop to 32°F (0°C) or lower. In this situation, mini-split heat pumps can maintain your garage’s temperature at 75°F (24°C).

Many mini-split 75°F (24°C) brands can also effectively cool your space up to an outside temperature of 115°F (46°C).

Mini-splits are especially a good option for warmer regions. They may lose half their heating capacity when the temperature drops below 17°F (8°C). You may need to install a special mini-split called an arctic mini-split for such cold temperatures.

During AC installation for your mini-split, you need to ensure the cooling capacity of the air conditioning device matches your climate. This is usually specified in the manufacturer’s sheet of instruction.

So, the simple answer to whether a mini-split is a great air conditioning option for your garage is yes. You, however, have to be sure you are getting the right one for your climate. 

What Size of Ductless Mini Split is Appropriate for Your garage?

Just like any regular indoor unit or outdoor unit, you have to get the right size cooling system for your garage. This also applies if you would love a ductless mini splits for sunrooms

Many people think that getting a more extensive heating and cooling system will give better results. This is not always the case. We give you a quick guide in helping you determine how many BTUs are needed for your garage space.

Best mini-split air conditioner size for Small Garage

The larger the garage, the more BTU is needed.

You will need a 6,000 or 9,000 BTU mini-split for a small one-car garage.

You will need a more powerful air conditioning system for a two-car garage. Install 9,000 to 12,000 for your two garage spaces for best results.

 The Best ductless mini-split system for Big Garage

 Typically, a three-car garage can be anything from 32 ft by 22 ft to as big as 40 ft to 30 ft.

These are significant size variations and may also affect the ideal size mini-split for your three-car garage.

However, for 32 ft By 22ft, we recommend you go for a 15,000 to 18,000 BTU mini-split. For large garages of over 40 ft, you will need a 30,000 or 36,000 BTU mini-split. 

Ensure you know the dimensions of your garage Before installing your air conditioning system. A simple “AC service near me” search will land you professional help from HVAC experts if you are unsure.

Can I Install the Ductless Mini Split Myself?

Yes, you certainly can install the ductless mini-split on your own. It is an age of DIY, and everyone wants to save some money.

However, just because you can do it does not mean you should. Do not even try if you don’t have the needed knowledge. This is because some work may need a professional hand and understanding.

First, the refrigerant line of your mini-split must be cut and charged. We highly recommend that all matters involving refrigerants should be left to professionals. You do not want to get anything wrong.

If you choose to do the AC installation yourself, we recommend only doing the air handler and the air condenser. You can then call an HVAC professional to set up the refrigerant line.

Other than setting up the refrigerant line properly, a professional HVAC technician will ensure:

  • you get the correct size mini-split depending on the dimensions of your garage,
  • the mini-split is installed in the correct location,
  • get an outdoor unit for support installed correctly if you need it.
