Garage Air Conditioners: A Guide to Cooling Your Garage

What is the best AC for a garage?
The best air conditioner for a garage is a ductless mini split system. It operates independently from the main house, ensuring no dangerous fumes (like carbon monoxide) enter your living space. Mini-splits are highly energy-efficient, offer both heating and cooling, and can handle the extreme temperature fluctuations typical of garages.
Why are Ductless Mini-Splits the Best AC for a Garage?
David Fowler, owner of Family Heating and Air in Pensacola, Florida, explains why mini splits are a great option for garage air conditioners.
“One of the most beneficial things is that the system is separate from your main HVAC unit,” Fowler said. “Typically, your main unit doesn’t have enough capacity to handle a garage, and adding the load can cause it to struggle.
“Another issue people often overlook is safety,” he continued. “Using your main system for the garage can allow carbon monoxide from a car or other device to enter your home. A mini split keeps the spaces separate. Plus, you can turn it on and off as needed, and they’re very efficient.”

What Should I Consider When Choosing a Garage AC Unit?
When selecting a garage AC unit, focus on cooling capacity (BTUs), energy efficiency ratings (SEER2), and durability. Because garages are often poorly insulated compared to the rest of the home, choosing a unit that can handle extreme temperatures without driving up energy bills is essential.
6 Key Factors for Selection
1. Cooling Capacity (BTUs)
First, determine the cooling capacity your garage needs, measured in British thermal units (BTUs). A well-insulated garage may require a smaller unit, while a larger or poorly insulated space will need more power. Work with a Bryant Certified Ductless Pro to calculate the correct BTUs for your space.
2. Energy Efficiency
Look for a garage AC unit with a high SEER2 (Seasonal Energy Efficiency Ratio) and EER2 (Energy Efficiency Ratio) for cooling, and a high HSPF2 (Heating Seasonal Performance Factor) for heating. Higher ratings mean lower energy costs and a smaller environmental footprint.
3. Garage Size and Layout
The size and layout of your garage—whether it's a small, enclosed space or a large, open area—will influence which type of air conditioner is most suitable.
4. Heating and Cooling Needs
If you plan to use your garage year-round as a workshop, gym, or living space, consider a mini-split system that offers both heating and cooling. Many models provide reliable heating even in very cold temperatures.
5. Noise Levels
Choose a garage air conditioner with low noise levels, especially if you spend a lot of time in the space. Bryant systems are designed for quiet operation, ensuring your activities aren't disrupted.
6. Durability
Garages can experience significant temperature fluctuations. Select a durable mini-split designed to withstand these conditions for long-lasting performance and reliability.
Installation and Maintenance for Garage ACs
Installing a garage AC unit costs between $3,000 and $8,000, depending on the complexity and electrical requirements. Professional installation is critical to ensure the warranty remains valid and the unit operates safely.
Installation Tips
It is highly recommended to hire a professional HVAC technician. DIY installation can lead to refrigerant leaks, poor efficiency, and voided warranties. A pro ensures compliance with local building codes. Learn more about mini split installation.
Maintenance Checklist
To keep your mini split repair costs low, follow these steps:
- Filter Care: Perform air filter replacement or cleaning every three months.
- Annual Checkups: Schedule mini split maintenance with a dealer to check refrigerant levels and coils.
How Can I Make My Garage AC More Efficient?
To maximize efficiency, insulate your garage walls and garage door to prevent thermal loss. Additionally, use a programmable thermostat to only cool the space when it is in use, and seal any gaps around windows or doors to keep the cool air inside.
