Was quoted 4010.00 for ac unit installed including ductwork from same company canaduct.com and, at the end, was told I had to pay for duct cleaning because he saved me half HST? In the end I saved 15 dollars not 200! And BTW most 1.5 ton go for 1500..so is it right that a 4 hr job costs the homeowner 2500 plus? I think not. Not happy.
