The reason in righting you is because of something that happened to my girlfriend. She had some issues with her Heating system in her house. So she called Haven home climate care. There service guy showed up and did a inspection on the unit and charged her for one hours work. then told her that she would need a new gas valve the cost of the gas valve would be 350$ and she would need a new heat exchanger but it was cover under warranty so the cost of removing it and replacing it would be 1500$ for labor . In all the cost of the work was 2500$. A little high. The next day they had their sales guy call to set up a appointment to try to sell her a new Furnace. These were she calls me and I look for a 2nd opinion. She called in Exclusive cooling LTD. I was there to meet the guy. The unit needed a gas valve (I agreed with him when he did the testing, I'm a 2nd class power engineer, and I do have a back ground in this area) It needed a new heat exchanger. The cost would be about 2 hours work at 75$h so that works out to 150$. This were I find it funny that it would cost 10x the amount from one contractor to the other. Here a little back ground about my Girlfriend. She's a Russian Canadian. She moved to Canada to get away from people who take advantage of a situation. She has reported this to the better business bureau. Just figured you would like to know this.
