AC Unit Replace
The Whynter Elite ARC-122DS used to be our top pick. If you absolutely want or need a dual-hose model—if you’re trying to cool a poorly ventilated room with a furnace or boiler, for example—this is the portable AC to get. After taking another look at it, we concluded that it’s still a great portable air conditioner, but we didn’t think the cumbersome bulk of the second hose added enough to the efficiency or experience to set this model apart for most people. (If you live in an area that frequently gets above 95 degrees or so, a dual-hose model might be worth using, according to one DOE study [PDF].) At only 57 pounds, this Whynter model is surprisingly compact, and it’s pretty quiet, too, though not as quiet as our other picks. The Whynter Elite ARC-122DHP is another former pick that’s essentially the same, with the addition of a built-in heater.climatisation Care and maintenance The most important thing to do to make a portable AC perform at its best is to insulate the gaps between the window, the window frame, and the panel holding the AC vent. Foam strips work, and 10 feet of the stuff typically costs a few dollars. The tape will help prevent warm air from slipping in through cracks as easily. When using the AC, keep it as close to the window as you can, with as many of the accordion ribs collapsed as possible, so the hose is as short and straight as you can make it. Clean the filter at least once a month. AIR CONDITIONER SYSTEMS When selecting an air conditioner for your home, you have an array of choices. We have the information you need to research your options, whatever your budget or your needs—from a single air conditioner to an entire Carrier system. Our lineup of central air conditioners allows you to choose the best solution to meet your needs. After all, we’ve been focused on cooling indoor spaces since our founder, Willis Carrier, invented the first modern air conditioner system in 1902. From air conditioners to furnaces, heat pumps and more, Carrier has all of the products for your home comfort. One of the great ironies of climate change is that as the planet warms, the technology that people need to stay cool will only make the climate hotter. By 2050, researchers expect the number of room air conditioners on Earth to quadruple to 4.5 billion, becoming at least as ubiquitous as cell phones are today. By the end of the century, greenhouse gas emissions from air conditioning will account for as much as a 0.5-degree Celsius rise in global temperatures, according to calculations by the World Economic Forum.
