I'm looking to replace the furnace in a house I'm moving into. I've noticed that every time someone asks a question about Brand X vs. Brand Y, the answer is - "they're all similar - the important thing is the install."
So how do you gauge the quality of the install when you're shopping around? I've had three different companies visit so far. Two spent quite a bit of time looking around and going over the options and prices. The third salesman bolted through the house like it was on fire and told me he'd email me the quote (that was last Friday and I haven't heard back). No one did any heat-loss calculations, although the first company measured all the windows and directions they were facing (but not the exterior walls, ceiling heights, and no inquiries about insulation).
The two quotes I've received so far are comparable in price.
Do I get another couple of quotes? What do I look for? Is anyone going to do a heat loss calculation or do I have to ask? Both the companies that quoted are service companies (big franchise/chains). Do they typically do quality installs? They both say they don't sub the work out - it's all in-house installers.
I'd very much appreciate any help or insights...
