It should be about $300. Don't use Sears - it's too expensive!
We had Ottawa Duct Cleaning, a family owned and operated company, done the duct Clean last Oct. and very happy with their service and reasonable price. Please check the following website or call 613- 836 7705. We had a horrible experience dealling with a fence company, then whenever we look for a service provider, we will check Better Business Bureau (BBB ) for feedback. :blowzy:
