Top 7 Best Mini Split For Garage

Doing maintenance work in your garage is best for relieving stress until summer arrives. Without proper garage cooling, it becomes a nightmare to do anything in the scorching heat. By using a good air conditioner, the garage’s working conditions can be favorable. Mini-split systems are ideal for a confined space like a garage.

The mini split air conditioners offer one of the most efficient ways to handle heat and humidity. They consist of an evaporator mounted on the inner walls and a condenser unit mounted on the outer surface. Heat exchanges happen in these two components, which cools the surrounding air. Before learning about the mini-split units, we must know a few governing parameters.

  • BTU: The BTU rating is the most familiar term for buying an air conditioner. The British Thermal Unit (BTU) refers to the cooling capacity of a mini split unit. Measured in BTU/hr, it gives the user an idea about how well the mini split will cool. For consigned spaces like a garage, the mini splits offer a cooling performance of 12,000 to 36,000 BTU/hr.
  • SEER: The Seasonal Energy Efficiency Ratio (SEER) is the most important parameter of a mini split’s performance. With this ratio, the efficiency of a mini-split is determined. The unit must offer good cooling performance with optimal usage of energy. The higher the SEER rating goes, the unit will be more efficient. Usually, mini spits are certified with ratings between 15 to 25.
  • Room Size: The size of the room where the mini split will be installed matters too. The cooling space eventually helps decide the other technical specification like the BTU of a mini split air conditioner. The size of the room (sq. ft) is compared to the BTU capacity of the mini split to check whether the unit is suitable for the room or not. These units easily cover rooms sized between 500 to 2000 sq. ft.

By understanding these parameters, one can select the best mini split of their garage. Since investing in a mini-split is a one-time thing, users may get confused between various units. This article includes a detailed list of the best mini splits to address this situation. A “Buying Guide” is also included to help the user understand a few important factors.

Buying Guide For The Best Mini Split For Garage

Due to the mini split air conditioner, a comfortable temperature is maintained in the garage. They are ideal options for confined spaces due to their compact size compared to centralized units. We have already gone through a detailed list of some best options. However, a user must be aware of a few parameters about mini splits. By considering these parameters, one can narrow down the best mini split for their garage.

1. BTU

The cooling capacity of a mini split is an important factor that gives the user an idea about its cooling performance. It is usually measured per hour in the British Thermal Unit (BTU). The BTU depends on various factors like the size of the room, the temperature difference, etc. For the garage, mini splits with a cooling capacity of  12,000 to 24,000 BTU is enough. When more cooling power is needed to compensate for the rising temperature, 36,000 BTU/hr capacity units are also available.

2. SEER

The Seasonal Energy Efficiency Ratio is a simple measurement of the efficiency of a mini split. The cooling process of any air conditioner comes at the expense of energy consumption. These units are tuned for better cooling with lesser energy consumption to avoid heavy energy bills in the summer. SEER is usually made mandatory by various governments to promote energy-saving electrical devices. A higher SEER value means less energy consumption and thereby a lower energy bill. The mini-split ACs usually have a SEER value between 15 to 25.

3. Room Size

To cool a garage, the mini split has to offer better coverage. The size of the room or garage has to be suitable for the cooling capacity of the mini split. The coverage area is usually mentioned on the unit. Buying a mini split with a coverage capacity of more than the actual room size is advised. Most mini splits easily cool rooms between 500 to 1000 sq. ft. For larger garages, some units can cover an area above 1000 sq. ft, up to 2000 sq. ft. A user can also select a mini split with the help of a BTU and square foot area chart

4. Power Source

The mini split air conditioners consist of components like compressors which need a stable power supply. The compressor allows the movement of coolant through the evaporator and condenser. The cooling fan also helps the circulation of fresh air in the garage. Most of the mini-splits run on an AC power supply. The power supply ranges from 110 to 240 volts depending on the power circuit. The unit must be connected to a specified power inlet to avoid damage or zero operation condition. The mini splits are plugged into a power supply via a power cord.

5. Refrigerant

A refrigerant is a cooling medium that is used to transfer heat from indoor air to outdoor air. The selection of refrigerant is important as every type has different properties. The most common refrigerant used in mini splits is the R-410A from the hydrofluorocarbon (HFC) family. It is made up of two different HFC refrigerants like R-125 and R-32. This enhanced refrigerant has a good cooling ability, works under high pressure, and poses less threat to the environment. The refrigerants must be chosen carefully as their leaks can damage the ozone layer.

6. Warranty

Warranty is given equal importance while purchasing a mini split for the garage. Since a user is investing money in a mini split, a warranty ensures safety against accidental damages. Some brands offer a warranty and free maintenance plan, to repair or replace the damaged component. The mini splits usually have a warranty period of 5 to 7 years. Some brands even offer a warranty of up to 12 years to guarantee a certain product quality. The user must check everything covered under warranty to avail it whenever the need arises.

Mini Split For Garage – FAQs

1. What size of a mini split is suitable for a garage?

Ans: The size of a mini-split system depends on several factors like the size of the garage, the surrounding temperature, etc. The user must check the overall area needed for cooling. The area is then matched with a suitable BTU rating to ensure perfect cooling of the garage space. Other factors like the type of refrigerant also help in selecting the right size of mini split for the garage.

2. Do mini-split air conditioners require frequent maintenance?

Ans: Mini-split ACs deal with a huge amount of air and humidity. These units thereby need regular maintenance to ensure durability. The air filters are cleaned to allow efficient filtration of outside air. The refrigerant level is also checked for the refilling process. The coils of the condenser and evaporator are also cleaned to ensure better heat transfer. Any damage to electrical wiring is also done to prevent malfunction.

3. Can a user install a mini-split system in a garage by themselves?

Ans: Due to the smaller size of mini split systems, it is possible for a user to mount them. But the installation process is always done by a skilled person with knowledge of electricity and refrigeration systems. The technician uses their knowledge to mount the various components of the mini split perfectly. This helps prevent electrical hazards, refrigerant leakage, or improper placement of the unit.

4. Does the mini-split system have a loud operational noise?

Ans: Compared to the window units, the mini split ACs have a quieter operation. But these units still have a noticeable noise output depending on the load or setting. The inner unit (evaporator and fan) is silent and produces over 20 to 50 dB of noise. The outdoor components like the condenser and compressor, are louder, with a noise output between 30 dB to 70 dB.

Conclusion

The mini split system offers a cost-effective solution to cool down the garage. Due to these units’ smaller size and installation, they have become a popular alternative to other air conditioning units.
