Which Is Better-Central Air Vs. Evaporative Cooling

You may consider buying an appliance to lower your home’s temperature if you live in a hot climate. You may find one cooling method works better for you depending on your climate and needs. Evaporative coolers (also known as swamp coolers) and central air are the two main cooling appliances that can lower your home’s temperature and make it more comfortable. Both can cool your home, but they work in different ways. Here we go with the explanation of evaporative cooler vs central air .

Cooling Method

Swamp coolers can be used to cool the air in homes that are located in low humidity areas. The coolers work by passing the air through a moist pad. The pad’s water evaporates into the atmosphere, cooling it and adding moisture or humidity. To ensure the swamp cooler is functioning properly, it must be controlled and constantly added to. It may not work in areas with limited water supply.

Central air transfers heat from your home. The central air uses a cooling agent, or “refrigerant”, which is contained within a closed system in the A/C unit. The heat from the home is drawn into the unit through a vent. It then absorbs the refrigerant. This changes from a liquid to gas and travels down the system to a compressor.

The compressor works by using high pressure to increase the temperature of the refrigerant and push it further down the system. It then passes to a condenser. This is typically located outside or at the back of the unit. Here it is exposed to the air and absorbs heat. The refrigerant turns into a liquid as it cools. It then flows back to the beginning of the system to absorb more heat and restart the cycle.


Swamp coolers can add moisture to dry air, making your home more comfortable. The swamp cooler is not recommended for use in high humidity areas. It will make these levels worse, which can lead to mold and mildew growth.

You can achieve the opposite effect by using central heating which removes moisture. Air conditioning can make a home more comfortable in high humidity areas by drying it slightly. A central air conditioner can dry out the air in areas with low humidity. This could cause problems for your eyes and skin.


Swamp coolers and central airs come in a variety of sizes and installation options, depending on where they are being installed. While portable and window air conditioners may not require professional installation, a central AC unit will need a professional hookup. The ductwork may have to be reconfigured or added if the unit is requiring ductwork. Although a ductless system is possible to retrofit a home with no ducts, it will still require the expertise of an electrician and carpenter to install the unit.


There are a variety of prices for central airs and swamp coolers, depending on their type, location, and whether a professional installation is required. You can spend a lot on either a swamp cooling unit or an A/C unit.

Climate Considerations

Swamp coolers work best when it is very hot and dry as those in desert regions. Because they add moisture to the atmosphere, this is why they are so popular. A swamp cooler can cause excessive humidity and mold growth in humid environments.
