A gas air conditioner runs on natural gas, and it has several advantages over conventional electric AC systems:
1.) A gas AC unit typically requires 30 to 50 percent less energy than an electric home cooling unit.
2.) Gas air conditioner units are also suitable for multi-zone cooling since they require minimal duct work. These HVAC units use sealed refrigerant, so they don't need to be recharged and are environmentally friendly.
3.) Gas ACs don't need compressors and have few moving parts, so they require little maintenance.
4.) The upfront cost to install a gas AC is generally higher than an electric system.
5.) Yet a gas air conditioner can last twice as long as an electric AC system.
