Is portable A/C effective in cooling large rooms?
That depends on the size of your unit. Small portable units with cooling capacities of about 8000 BTU are perfect for a 300 sq. foot room, while larger 24000 BTU air conditioners can effectively cool a 1000 sq. foot room. So, as you can see, a properly sized mobile air conditioner can do a good job even in a very large room. However, you should know that larger doesn’t necessarily mean better. An air conditioner that is too large will consume more energy and won’t cool your room effectively, because it will stop and start constantly. Portable air conditioner energy efficiency Everybody knows that air conditioners chew a lot of energy, so energy efficiency is a big issue. However, recent developments in technology allow manufacturers to produce very efficient air conditioners. A few years ago an EER (energy efficiency ratio) of 6 or 7 was considered good. Now the standard is 12 or higher. Modern portable air conditioners are as energy efficient as window or mini split units. To select t
