Range exhaust hoods in the home are more important than most realize. They serve some very key functions in the kitchen and home. They effectively remove heat if they are vented. They remove airborne grease residue by trapping it in a filter and they remove chemicals and odors by venting it outside or trapping it in a charcoal filter.

There are vented and non-vented exhaust hoods. The non-vented exhaust hood normally uses a charcoal filter along with a steel wool type of filter. The charcoal filter purifies and recirculates cooking exhaust. The steel wool filter traps airborne grease. The vented range exhaust hood uses only a steel wool type of filter to trap airborne grease particles. It removes most of the exhaust to the outside.

Maintenance of both types of range exhaust hood is important in keep them operating effectively. If the filters become clogged, they won’t do their job properly. The grease trap should be cleaned at least every month and more often if a lot of fried foods are being cooked. The charcoal filter should be replaced every three to six months, depending on how much cooking is being done.

After several years of use an exhaust range hood motor may go out requiring replacement of the motor or the entire unit. Due to the low expense of most hoods, it is probably more desirable to replace the unit than to repair it. Chances are the old unit is becoming unsightly by this time. The unit can be replaced by a person who is handy with tools and has a little knowledge of electricity, or a handyman can be sought for the job.

For the do-it-yourselfer, usually all that is needed is a Phillips head screwdriver. Most are held in by four screws. After turning off power to the unit, wiring is a simple matter of connecting the black wires together and the white wires together, and the green wire will mount to the unit someplace. The easiest way to do it is to pay attention to the wiring as it is originally and put it back the way it was. Wire nuts are usually provided with the replacement unit for making the connections. If there are any doubts about how to do it get a professional.

When buying a replacement hood it is best to check the CFM of the unit and to get a unit that is equal or greater than that CFM. CFM refers to cubic feet per minute of air moved. It is of utmost importance to get the right type of unit as regarding ducted or non-ducted.
A properly working range exhaust hood will help keep a kitchen clean, and help keep smoke from setting of the smoke detector. These two facts make them a wise investment!
