Let’s get started.
Common Garage Air Conditioner Issues
Throughout their lifespan, garage air conditioners will have several issues that can affect their performance and longevity. Here are some of the most common issues you may encounter and the solutions for each:
Clogged Air Filter
Over time, the air filter in your garage air conditioner can become clogged with dirt and debris, reducing airflow and causing the unit to work harder than it needs to.
Reduced cooling efficiency, increased energy bills, and unusual noises.
To troubleshoot this issue, turn off the power to the unit and remove the air filter. Clean the filter with water and mild detergent, or replace it with a new one.
Refrigerant leaks can cause your garage air conditioner to malfunction and stop cooling effectively.
Warm air blowing out of the unit, ice buildup on the evaporator coil, and hissing or bubbling sounds.
A refrigerant leak is a more complex issue and requires a professional HVAC system technician to diagnose and fix the problem.
Electrical problems can cause the unit to stop working entirely or intermittently.
The unit won’t turn on or turns off randomly during operation.
Check the circuit breaker or fuse box to ensure there’s no tripped circuit. If that doesn’t solve the issue, call a professional to inspect and repair any electrical problems.
Dirty coils can reduce the cooling efficiency of your garage air conditioner, forcing the unit to work harder than necessary.
Reduced cooling efficiency, increased energy bills, and unusual noises.
Turn off the power to the unit and clean the HVAC coils using a soft-bristled brush or a vacuum cleaner with a brush attachment.
A faulty thermostat can prevent your garage air conditioner from turning on or off properly.
The unit won’t turn on, turn off, or maintain a consistent temperature.
Check the thermostat’s batteries and settings. If that doesn’t solve the issue, replace the thermostat with a new one.
Faulty Fan Motor
The fan motor in your garage air conditioner helps to circulate cool air throughout the unit. When the fan motor is faulty, it can cause the unit to overheat and shut down.
The unit won’t turn on, unusual noises, or reduced cooling efficiency.
Turn off the power to the unit and check the fan motor for any signs of wear or damage. If you notice any issues, contact a professional HVAC technician to replace the fan motor.
Water leakage can occur when there’s a clogged drain line or a malfunctioning condensate pump.
Water pooling around the unit or dripping from the unit.
Turn off the power to the unit and check the drain line and condensate pump for any clogs or damage. If you notice any issues, contact a professional HVAC technician to repair or replace the faulty components.
Frozen Evaporator Coil
The evaporator coil in your garage air conditioner can freeze when there’s a lack of airflow or refrigerant leaks.
Reduced cooling efficiency, warm air blowing out of the unit, and ice buildup on the evaporator coil.
Turn off the power to the unit and let the ice melt. Then, clean the air filter and check for any refrigerant leaks. If you can’t find any leaks, call a professional HVAC technician to diagnose and fix the problem.
By understanding these garage air conditioner issues and their symptoms, you can troubleshoot problems before they worsen and avoid costly repairs.
Additional Tips for Your Garage Air Conditioner
Maintaining and troubleshooting your garage air conditioners regularly can help prolong their lifespan and prevent costly repairs. Here are some additional tips and tricks for keeping your unit running smoothly:
Schedule Regular Maintenance
Schedule an annual maintenance appointment with a professional HVAC technician to inspect and clean the unit, check for any leaks, and ensure it runs efficiently.
Keep the Area Around the Unit Clean
Clear any debris, dust, or leaves around the outdoor unit. This ensures proper airflow and helps to prevent clogging of the condenser coil.
Check the Ductwork
Check the ductwork for any leaks, gaps, or damage. If you notice any issues, contact a professional to repair or replace the ductwork.
Use a Programmable Thermostat
A programmable thermostat can help you save energy and reduce costs by automatically adjusting the temperature when you’re away from home.
Replace Air Filters
Replace the air filter every one to three months, depending on usage, to ensure proper airflow and cooling efficiency.
Keep the Unit Level
Ensure the unit is level, as an unlevel unit can cause water leakage and other issues.
Regular maintenance and cleaning are essential for ensuring your garage air conditioners run smoothly and efficiently. It’s important to clean the unit and replace the air filter regularly to ensure proper airflow and cooling efficiency. Additionally, scheduling an annual maintenance appointment with a professional HVAC technician can help to identify and prevent potential issues before they worsen.
By following these tips, you can keep your garage air conditioning system running smoothly and efficiently for years to come.
When to Call a Professional
While DIY maintenance and troubleshooting can help you fix many common issues with your garage air conditioner, there are instances where it’s best to call a professional HVAC technician. Here are some scenarios where DIY troubleshooting may not be enough, and it’s time to call in the pros:
If you have an electrical wiring or circuitry issue, it’s best to call a professional HVAC technician to inspect and repair the problem. Electrical issues can be dangerous and should be handled by a trained professional.
It’s also important to call a professional HVAC technician if you suspect a freon leak. Refrigerant leaks can be dangerous and cause serious health problems if improperly handled.
If you have an issue with the fan motor, compressor motor, or any other motor component, it’s best to call a professional HVAC technician to diagnose and repair the problem.
If your garage air conditioner is making unusual or loud noises, it’s best to call a professional HVAC technician to inspect and diagnose the problem. Strange noises can indicate a serious issue with the unit and should be addressed promptly.
If your garage air conditioner is still under warranty, it’s best to call a professional HVAC technician to inspect and repair the problem. Attempting DIY repairs can void the warranty and result in costly repairs.
In summary, DIY troubleshooting can help you fix many common issues with your garage air conditioner. However, there are instances where it’s best to call a professional HVAC technician to inspect and repair the problem. If you’re unsure about a problem or don’t have the necessary tools or knowledge to fix it, it’s always best to call a professional.

Ultimately, it’s up to you to decide if an air conditioner is necessary for your garage based on your needs and preferences.
What are the Benefits of a Garage AC?
