To test portable air conditioners, we heat the climate -controlled room at 92 degrees. Once the room reaches 92 degrees, we turn off the heat and turn on the AC transmission unit in cooling mode, with a medium fan speed and a set temperature of 68 degrees. We perform the unit for 2 hours and 30 minutes and repeat the same test twice per unit of AC. Then we use the data collected during the two -way measurement tests:
- How much permanent transmission air conditioner keeps the room within 5% of 68 degrees
- How much did the room constantly maintain within 5% of the individual lowest temperature of the AC unit
Once we have this information, we compare the results through the units to see which maintain the set temperature for the longest period of time. We also see which units maintained their individual lowest temperature for the longest time. We have done this so that if the unit does not reach 68 degrees in the allocated time, we were still able to monitor how constantly maintaining the lowest temperature it has achieved. The higher the percentage, the better the unit is performed.
When looking at performance, it is important to note that the units we tested have no identical specifications, so direct performance comparisons are not the only thing we consider to arrive on our list of best transmission air conditioners. We also look at the features of the unit and other options regarding its price and specifications to determine its overall value.
We also do not draw comparisons of direct performance when looking at units of very different sizes and opportunities, say, MAP 12,000-BTU MIDEA MAP14HS1TBL versus 5,500-BTU Frigidaire FHPC082AC1. For this reason, we compared the results of performance in two groups based on the area of coverage. Specifically, we compared the smaller models of Midea, Black+Decker, Frigidaire, Whirlpool and GE (which all have areas to cover up to 350 square meters) have areas covering from 500 to 550 square meters) against each other.
