I saw their ad in kijiji. They operate with different names. One is "Cora duct cleaning" and other is "ducts cleaners".
Their ad states that they will clean all vents including j vent, sanitize and will inspect furnace, ac coils, dryer and dryer vent. They claim they have NADCA & TSSA certification also.
On 4th February, they sent 2 people who were just the hired labors. They cleaned each vent for 1-2 seconds only by using compressed air. Whole cleaning took place for 15 minutes only while they were claiming 1.5-2 hours depending on my house size. After cleaning, the labors were telling me that i need full cleaning of ducts which is done through agitators/strips and cost $450 but they were willing to do that in $100 only if i dont tell to their boss.
They didnt do j-channel cleaning, senitization and inspection of above stated appliances.
I complained them on 6th february and they said they are looking at complain and that they had received similar complaints from other homeowners. I waited for a week and started calling their 1-877-563-5661 and talked to "Sunil" who arranges team. He told me he will call back but he never called back. Then somebody blocked my number. I left several voice messages. Talked to owner "shazia" several times and "sunil" but no go.
I have decided to complain to "ministry of consumers" and "durham police" about their shady business.
