Called Breath Pure Air Air Duct Cleaning after seeing their ad in MoneySaver.ca. Set appointment for March 14, 2018. 2 men came. One stayed in kitchen talked with us while other went downstairs. Then told go downstairs where we were shown the furnace. Was told there was mold and would need to have benefct fogging costing $489, then clean coil evaporator for $349, plus advertised cost of $139. Total would be $977 plus tax of 124.00 for total of $1101. but could get better price if we paid cash $900.00 which we paid. Was not happy next day when the ducts were looked by at us. This time took 1 1/2 hours in total. Called to 800-943-3828 left messages 8 times which after several days finally got call back. Spoke to Customer service . They would get back to us later. No response until I sent emails in May. Then June 19 received email to call service manager and see what they can do. So left messages for one week. They got back to us after I sent them a copy of the invoice with their name on it but no amount was filled in. July 8, 2018 They told us they didn't recognize the invoice and their service man of 15 years is in Cambridge and Kitchener and we were told our name is not in their system. We were told companies go round pretending they are representing companies which they really are not. (The truck came to our house and now wish I had taken down the license plate number which I will do in the future. The man upstairs must have seen the words "SUCKER' ON OUR FORHEADS. Then we notice another ad but this time it was called Cambridge Pure Air Air Duct Cleaning. With same phone number as previous advertisement. Imagine paying $600.00 per hour for the duct cleaning. No product was used. Only sucking dirt.
