I usually don't write the review and complain about the service, but want to give heads up that yesterday we had the technicians visited our house for cleaning the duct lines. First, I am not sure this is a kind of same approaches that other contractors uses, but they missed several spots in the quote process and suddenly asked us to pay more because the duct counting was not correctly done. In addition, the quote should include the exhaust fan cleaning as well (I was told this), but they asked about $130 per each additional lines in the bathroom, adding up to $500... I chose this business because I thought that the cost is fair and good google review than other contractors. However we eventually have paid more than that other company asked. Furthermore, I spent whole afternoon until 9 pm to clean up all the dust flowing on the floor and mattress, it looks like I tried to clean the house and have better air quality, but it is actually not, living with old dirty dust. Also, the technician left the house without checking air flow and vent dampers' position, so I had to figure out air circulation, because the dampers in the main supply was closed and no airflow when I turned AC on. Although I appreciated the time that they took to clean the ducts, but this is not what I expect to deal with.
