I spent about $500 including tax. So please double check the price. Ask them how much you should pay in total (are there any hidden fee?). I used the company www.advancedairquality.ca The service person seems professional, but it is difficulty to say whether my duct system gets much cleaner or not. Check this http://www.cmhc-schl.gc.ca/en/co/maho/gemare/gemare_011.cfm for more info. Good luck!
