Like every other appliance in your house, portable air conditioners make noise. If you’re considering a unit in a bedroom, or wherever noise may pose a problem, check to see that the model runs quietly. Many models run around 50 decibels, which blend into the other ambient sounds and become a low level white noise. But some portable air conditioners are quite loud, so if you’re concerned about noise levels, have a good look at the decibel ratings. The higher the decibel, the louder it is.

Haier HPN14XHM 14, 000-BTU Portable Air Conditioner, 11, 000-BTU Portable Heater Combo Unit

This large, 14,000-BTU portable air conditioner is on our quiet list not because it is ultra-quiet, but because it generates a relatively low volume of decibels in comparison to other units of its size and even compared to window units that are much smaller. This Haier is rated to provide cool and heat for rooms from 500 to 700 square feet and in our testing we indeed saw excellent results in a room of 700 square feet.

They’ve done a great job with their Quick-Install Window Kit that allows you to hook up the single exhaust hose through a horizontal or vertical opening. Many models have clumsy window venting kits, not this Haier. This strong cooling machine has three cool settings, three fan settings and a 24-hour on/off timer. Auto-evaporation makes this an almost maintenance free wonder with relatively quiet operation. It is one of the higher priced models, so make sure you need the extra cooling are larger capacity.
