Ricart also warns customers that the moisture fed into a home can wreak havoc on wood furniture and heighten the risk of mold growth, if it’s not controlled. On days when the mercury rises above 100, a swamp cooler might just drop the temperature in a home into the 90s. “A swamp cooler is never going to get you below 65 or 70, and that’s on a good day,” he says. Limits of a swamp coolerĪlthough you can still find swamp coolers in plenty of homes and home supply stores, Ricart says they’re less common than they were 10 or 20 years ago because they’re harder to control than their AC counterpart-and, as we mentioned, not too effective in especially hot climates. By comparison, your typical air conditioner is expected to last just five to seven years. What’s more, a quality unit can last for as long as 15 years, according to replacement estimates from the International Association of Certified Home Inspectors. The Department of Energy estimates that an evaporative cooler uses about a quarter of the energy consumed by a central AC system, and the purchase cost is about half that of central AC.īeyond the power usage, there are other green benefits to swamp coolers: They don’t require the use of refrigerants, the chemicals used in AC units that have been linked to global warming. When the inlet air velocity was 1 m/s, the outlet air temperature in Urumqi and Lanzhou could be reduced from 33.4 C to 24.2 C and from 31.3 C to 24.5 C. Swamp coolers are also less expensive than air conditioners, with smaller units going for anywhere from $150 to $350.Īlthough swamp coolers operate as plug-in appliances, there’s also the option of a down-flow installation, typically done by a contractor who will install ductwork throughout your home and mount your swamp cooler on the roof, allowing the unit to blow cool air into many rooms at once. Costs for this sort of project vary by area and the size of your home, but homeowners can expect to pay anywhere from $1,500 to $5,000 for the whole job. The dew-point evaporative cooler with fibrous membrane has good application prospects in regions with low humidity such as Urumqi and Lanzhou. There are also models with wheels on the bottom, allowing you to move the swamp cooler from room to room the way you might move a fan to cool different areas of the home. Swamp coolers vary in size, and some can be installed in a window, similar to a window AC unit. Claim your home to stay up-to-date of your home‘s value and equity.
