I am deciding on a new furnance could you advice on Brand and model. My old one is a westen house, my house size is about 1200 square foot one floor 3 bedrooms. I need to put a horizantal one since my old one was in the crowl place and it floods all the time, so I have been told to install a horizantal. Could you give how mush should I expect to pay for an installer to do all the work, Thanks
