Portable AC units aren't as efficient as window air conditioners, but this video will provide some tips to improve your portable AC efficiency so it can more effectively and quickly cool down your garage or living space in the summer to maximize your cooling and save money.

The plastic round exhaust duct from the portable AC unit builds up and re-radiates a good amount of exhaust heat back into the room so this video will show you how to insulate the duct to prevent radiant heat from escaping back into your room allowing your portable A/C unit to cool off the space faster and more efficiently.

The video will compare before and after insulating the air conditioning exhaust duct using FLIR infrared imaging to test the effectiveness.
