Updating old auto air conditioning dating a persian jewish man
This combination of air conditioner and central heater eliminates the need for a separate furnace indoors.
Air supply and return ducts come from indoors through the home's exterior wall or roof to connect with the packaged air conditioner, which is usually located outdoors.
Packaged air conditioners often include electric heating coils or a natural gas furnace.
A preferable alternative is a dehumidifying heat pipe, which can be added as a retrofit to most existing systems.
If you have a central air system in your home, set the fan to shut off at the same time as the compressor, which is usually done by setting the "auto" mode on the fan setting.
Look for the ENERGY STAR® and Energy Guide labels -- qualified central units are about 15% more efficient than standard models.
