A quick, very efficient and professional (clean) installation. Kaz was courteous, experienced and skilled. My two story house was already roughed in, so the price included installation, hose and unit. I would highly recommend Kaz and Whirlwind systems to anyone looking into a central vac to have in their home. It's been an amazing addition and on a personal note; is fantastic with sucking up cat hair and helps prolong visits with my allergy ridden children. A++!
