The National Association of the Deaf (NAD) defines a person who is deaf as someone who is âunable to hear well enough to rely on their hearing and use it as a means of processing information.â Additional information can be found at the NAD site, http://www.nad.org/infocenter/ infotogo/dcc/difference.html.
A contractor will charge $308 to install a 14-inch power ventilator which includes the labor and material; you can do it for more than half and pocket a 57 percent savings.or about $130 you can buy what you need: a power ventilator, an electrical box and cover, a short piece of three-wire BX or Romex cable, a package of wire nuts and a quart of roofing cement.
For a home that is 100% prepared for an install, costs can be as low as $700, with a minimum 6-year warranty, but average costs in most homes range from $1,100-$1,400 and for homes with venting issues or significant drain requirements (P&T, and pans & drain) costs can range from $1,400-$2,000, installed.
