Create a Homemade AC

Creating a homemade air conditioner, while not as powerful as commercial models, can still provide relief during hot weather and serve as a fun DIY project. Here’s a simple guide on how to make a basic homemade AC unit using common household items:


  • Begin by cutting two holes in the lid of the styrofoam cooler or plastic bucket—one for the fan and one for the PVC pipe or tubing. Use a utility knife or scissors to make the holes, ensuring they are slightly smaller than the diameter of the fan and pipe/tubing.
  • Insert the electric fan into one of the holes in the lid, facing inward so that it blows air into the cooler/bucket.
  • Insert the PVC pipe or flexible tubing into the second hole in the lid. This will serve as the air outlet for the cool air.
  • If using a plastic bucket, you may need to drill holes around the top edge of the bucket to allow for airflow.
  • Fill the bottom of the cooler/bucket with ice packs or frozen water bottles. These will act as the cooling agent, chilling the air as it passes over them.
  • Place the lid with the fan and PVC pipe/tubing onto the cooler/bucket and secure it in place with duct tape, ensuring a tight seal to prevent air leaks.
  • Turn on the electric fan and position the homemade AC unit in a well-ventilated area, such as near a window or doorway. As the fan blows air over the ice packs or frozen water bottles, it will create a cool breeze, providing relief from the heat.

It’s important to note that homemade air conditioners may not be as effective as commercial models and may only provide temporary relief from hot weather. Additionally, they may require regular maintenance, such as replacing the ice packs or frozen water bottles, to maintain cooling efficiency. Nonetheless, creating a homemade AC unit can be a fun and practical DIY project, especially during the summer months.
