The bottom line is that portable air conditioners can be great assets but unless you seriously consider the job that you are asking your cooling unit to do, you may choose one that is not suitable. 2. Once you’ve found the perfect spot, set up your AC unit according to the instructions in the manual. This is because the instructions may vary according to the type of ac, and what size it is. If the unit is still not functioning properly, consult the user manual for further instructions. If you’re troubleshooting your portable air conditioner and still can’t get it to blow cold air, contact a professional for assistance. While both casement windows and sliding windows take the same type of air conditioning unit, they are still two completely different types of windows. A portable air conditioner window kit is designed to fit most standard windows and allows you to install your AC unit without having to drill any holes. Another trick for keeping an unattended car cool for your return: Leave your windows down-just a tad-to encourage airflow. Once installed, your portable AC unit will be able to vent properly and keep your home cool and comfortable all summer long.
