With this function, you can easily control your AC from anywhere using the free smartphone app. In addition to being very quiet and energy efficient, this model also has wifi connectivity. The adjusted CEC rating isn’t much lower, coming in at an impressive 10,000 BTU. The original ASHRAE rating for the LG Smart AC is 14,000 BTU. This efficiency is immediately apparent when you look at the BTU output. The dual compression chambers also mean this unit is much more efficient than your standard unit. That extra quiet operation, which is apparent on even the highest settings, is thanks to the dual inverter. On its lowest setting, this unit puts out just 44 dB. The LG Smart Dual Inverter Portable AC is the perfect solution for cooling larger rooms without creating a racket. Quietest Portable Air Conditioner Reviews We awarded extra points to those with eco-mode capability and features like auto on/off and timers. We searched for high-efficiency units capable of saving you some real cash. But not all portable ACs cost the same amount to run. Cost To RunĪll portable units are going to cost less to run than a full-house system. We paid particular attention to the quality of the materials used in each AC, user reviews, and the company’s reputation when selecting our top choices. Of course, efficiency, power, and noise output don’t mean much if the unit breaks down after only a few months of use. Because more efficient units are less costly to operate, we looked for units with DOE ratings that are aligned more closely with the listed ASHRAE rating. The DOE rating will be lower than the ASHRAE and is usually more accurate in determining how well the AC actually performs. This recycled air is pushed out of the house via the exhaust and is naturally replaced with warmer air from outside the room. This is because they must recycle cooled room air to cool down the internal components. This second rating is necessary because portable units are less efficient at cooling than their ASHRAE rating lets on. The DOE BTU rating, which can also be listed as a CEC rating, is an adjusted cooling power measure specific to portable units. The ASHRAE BTU rating is similar to your standard rating given to other types of AC units. Instead, you want to look for a unit with the suitable capacity or power to cool your room.Īnother confusing aspect of measuring AC power in portable air conditioning units is ASHRAE BTU versus DOE BTU. But bigger is not better when it comes to air conditioning power. Many consumers make the mistake of looking for an AC with the highest BTU rating they can afford. BTU is widely recognized as a heating unit around the world. BTU RatingīTU rating is an abbreviation of “British Thermal Unit” and is a unit of heat calibrated by the measure of power required to raise 1 pound of water by 1✯. You should expect a portable air conditioning unit to be on easy-glide casters. Look out for weight and features that make transportation easier. The units featured in this article have been chosen for their portability. For comparison’s sake, 40dB is the output of the average refrigerator pump, and 60dB is about as loud as the typical conversation between two people. If you want a unit that remains comfortably quiet no matter which setting you have it on, you’ll want a unit with a listed output as close to 50dB as you can get, which is what we looked for.ĥ0dB is about as loud as a moderate rainfall outside the window. Noise levelĪCs typically put off significantly higher decibels when running on medium or high than the marketed noise output. We also looked at each contender’s portability, how powerful it is, how well it is made, and how much it costs to run. How much noise an AC puts off is only one piece of the puzzle that determines whether a unit is worth buying or not.
