Experts tell us that it is safe to have your window air conditioner running 24/7. No part inside the air conditioner will get too hot and melt if you keep it running all day. The performance of the air conditioner, too, won’t suffer if you forget to turn it off.
For the best efficiency and effectiveness, stick with a unit that has a BTU level designed to fit your space. A window AC with too little BTU power will run continuously to try to cool a large space and, in the process, will eat up your energy budget.
The capacity of an AC, or its cooling ability, is based on its tonnage. However, split ACs are mounted high and designed for cooling larger spaces, whereas window ACs are better for air circulation in smaller rooms. Further, it is possible to get split ACs of a high tonnage, of above 2 tons.
Window AC units typically have to consume more energy because they have poor insulation levels. You see, window units allow a lot of heat indoors due to the way they’re installed. They’re simply placed into an open window, which allows: Hot unconditioned air to leak into the home.
