Swamp Coolers vs Air Conditioning

  • 2 of 3

Advantages of swamp coolers:

Swamp coolers use as little as a quarter of the energy of a standard central air conditioning system. The Sacramento Municipal Utility District estimates city residents can save about $150 per year on electric bills by switching to a swamp cooler. Savings can be far higher in hotter and drier climates.

Some utilities and municipalities offer rebates for swamp coolers.

Swamp coolers typically run on 120-volt power, so they can use standard outlets, rather than the separate and dedicated circuit that many air conditioners require.

Swamp coolers should cost less to install than central air conditioners, and may require simpler ductwork.

Swamp coolers do not use refrigerants that could be environmentally harmful. Many air conditioning refrigerant chemicals deplete the ozone layer and may contribute to global climate change.

Swamp coolers draw more fresh outside air into the home.

Swamp coolers are most effective at the peak heat of the day, when the air is typically driest.
