I have a weil-Mclain and I am pleased with it. Like many furnaces, it is loud but that is the nature of the beast!
Get three estimates. Two is not enough and four is too many!
You might want to visit your local Building or Plumbing Inspector and ask to see a permit (you will need one)for a similar job. They can't make referals but, they can give good advice.
Good luck from the seacoast,Jason
