Personal Experience

How do I air condition my garage without windows?

I recently installed an air conditioner in the garage of my house, which had no windows. As an expert in this field, I can attest that it was a more difficult task than usual, since most ACs are designed to be installed in well-ventilated environments with windows for better airflow. I had to be more creative and resourceful so that the AC could be properly installed and working in the garage.

First, I hung a vent fan from the ceiling to draw out the heated air from the garage. This was especially important since the garage was windowless and there would be no natural ventilation to move the air. Secondly, I installed a thermostat which was used to monitor the temperature and adjust the AC’s settings according to the garage’s temperature. I also added some insulation to the walls and the attic of the garage in order to reduce the transfer of heat.

Installation of the AC unit was not complicated but it did take some extra time and effort. I used heavy-duty mounting brackets to secure the AC securely above the ground and applied special sealant so that it would remain airtight. After connecting the AC to the power supply and setting the thermostat correctly, I tested the AC several times to make sure that the temperature was consistently cool in the garage. It was a successful job and the garage is now cooler than ever before.
