Garage Air Conditioners: A Guide to Cooling Your Garage
By Travis Baugh
A ductless mini-split system is often the best choice for a garage AC unit. These systems operate independently from your home's main HVAC, providing efficient, zoned cooling and heating without requiring ductwork. This guide will walk you through everything you need to know about choosing the right garage air conditioner.
Why are Ductless Mini-Splits the Best AC for a Garage?
A ductless mini-split system is an excellent option for a garage air conditioner because it operates separately from your home's main HVAC unit. This separation is crucial for both performance and safety.
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 the right garage AC unit, there are six key factors to consider to ensure you get a system that provides reliable, efficient comfort.
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.
How Do I Install a Garage Air Conditioner?
Proper installation is critical for the optimal performance of your garage AC unit. It is highly recommended to hire a professional HVAC technician to install the system correctly and in compliance with local building codes. A professional installation minimizes the risk of malfunctions and the need for future mini split repair .

How Can I Make My Garage AC More Efficient?
To maximize energy efficiency and reduce your cooling costs, implement these tips:
- Insulate your garage: Add insulation to the walls and ceiling to prevent heat transfer and keep cool air inside.
- Use a programmable thermostat: Set temperature schedules with a programmable thermostat to avoid cooling the garage when it’s not in use.
- Seal ductwork: Ensure any ductwork is properly insulated to minimize air leaks.
- Perform regular maintenance: Clean and maintain your garage AC unit regularly to keep it running smoothly.
What Maintenance Does a Garage AC Unit Require?
Proper maintenance is essential to keep your garage air conditioner running efficiently.
- Replace filters regularly: Air filter replacement is crucial for maintaining efficiency. Replace filters at least once every three months to ensure proper airflow.
- Professional mini split maintenance: Have your local Bryant dealer perform annual mini split maintenance to check for refrigerant leaks and ensure all components are working correctly.
