How do I choose a contractor to install a new furnace?

Question

I am looking to replace my furnace, and air conditioning systems. Since this is going to be a expensive job, and it requires wiring, and dealing with dangerous components (wiring, gas, etc), I want to hire a reputable contractor.

So far I have gotten 2 estimates. One is from Sears, and the other is from a local contractor that has repaired and maintained the furnace for many years. The Sears estimate is much lower than the local contractor's (about $3000 less). However, I am wary of hiring a Sears contractor because it's such a big company and because I have read many complaints about Sears servicing. How can there be so much difference in prices? Should I get another bid and if so how can I pick someone who is reputable and trustworthy? I know very little about this process.

Answer 1

Get as many estimates as you like.  The more the better.  Through out the top two and the bottom two. and pick the 3 or 4th from the top.  

Generally one can't go by estimates.  Ask all the contractors for References of people he has done work for.  

I knew of a company that would spend top dollar for adds their work was not that good.  Don't go by high class ads.

Answer 2

yellow pages, under furnace.  possibly the bigger the ad, the bigger and more reputable the dealer.  skip sears, and get 3 quotes over the phone.  that's why they're there.
