Refrigerated Air versus Evaporative Cooling
Keeping your home cool and comfortable during our hot desert summers in New Mexico is probably one of your biggest priorities. But should you use refrigerated air or evaporative cooling for your home? A side by side comparison from your friends at R & R Heating & Air may help you decide.
|Criteria||Refrigerated Air||Evaporative Cooling|
|How It Works||A standard air conditioning unit cools warm air it has taken from the rooms in your home by passing it over a set of coils that are filled with a refrigerant. The cooled air is then blown back into your home until the room or rooms reach the desired temperature.||A swamp cooler is a relatively simple open system. A fan draws in air from the outside and forces it through a set of damp pads. These pads are moistened by a small pump that draws water from a pan below the unit. The air causes the water to evaporate, which in turn cools the air that is pushed into your home.|
|Maintenance||A properly maintained refrigerated air system unit usually only requires seasonal maintenance and a regular changing of filters.||While a properly maintained evaporative cooling system may not require much maintenance, some units do require regular service throughout the summer to maintain an optimal level of cooling. They also require seasonal maintenance.|
|Repair||A properly maintained refrigerated air system shouldn’t require much repair, but when it does, the more complicated nature of the unit requires professional servicing.||Because of the relatively simple nature of evaporative cooling systems, some, but not all, of repairs can be of the do-it-yourself type. However, routine maintenance and more complicated problems should be done by a professional.|
|Indoor Air Quality||When filters are changed regularly, air conditioning units help improve and maintain good indoor air quality.||Evaporative coolers bring in outside air that could bring in pollutants and allergens. These could contribute to poor indoor air quality.|
|Cost||An air conditioning unit uses more electricity than an evaporative cooling unit. However, they do not use water.||Evaporative cooling units use far less power than air conditioning units, but they do use more water.|
|Special Considerations||Air conditioners take the moisture out of the air in your home, which can be a problem in our ultra-dry desert climate.||Swamp coolers require that doors and/or windows are cracked open to work properly. This could create a security risk. Swamp coolers also have a more difficult time cooling the home on humid days. Finally, they only cool the air about 20 degrees at optimal performance, so when the temperature tops a certain point, the air inside your home may still feel warm. Some days will just be too hot for evaporative cooling to be effective.|
