like the others on here, I felt like I was gouged huge for my furnace repair - $1200 to replace an 8 year old furnace where the fan failed and then there was a leak in the heat exchanger. The heat exchanger was covered under warranty but the labour wasn't. So we basically paid about $800 for a total of one hour of labour to install the fan and heat exchanger. Our AC has now gone and I won't be calling Harding. I did have another tech research the AC unit and was told it was only a 5 year warranty, but harding never registered the unit otherwise it would have been covered under a 10 year warranty. I am sure the same thing happened with our furnace.
