    furnace replacement what to look for?

    We are participating in an energy program in Alaska. We have a york p3u diamond 90 furnace that doesn't keep our house comfortable in the winter, basement is very cold and it runs on a high speed that is loud.
    We want something energy efficient and not loud. the unit is only 6 years old but our gas bill is running 3-400 a month in the winter.

    I would love any suggestions. I don't see anyone listed on the forum in AK to hire.
    This will be a large investment and I want to have it done right.

    Sincerely
    Kelli

    Several questions come to mind; what size furnace,natural or propane, general size and condition of house, was the airflow in cfm determined,and was it set up with a combustion analyzer?

    90% AFUE furnace is already better than the standard 80%, you have a pretty efficient furnace. Instead of replacing your furnace, maybe see if you can improve the house. Like secondopinion mentioned, what is the condition of the house? Do you have a leaky house? Do you have leak ducts? where is your furnace located? What kind of windows and insulation are there? Do you have heat recovery ventilators? etc...

    A $400 gas bill tells me the house needs to be fixed.

    I agree with looking at improving the house envelope/insulation. This will get you the biggest bang for your buck. Secondly, I would have the duct system evaluated. The best furnace in the world will do you no good with a poor delivery system. In my experience, about 75% of the duct systems I see are either undersized or poorly designed/installed.
    Where are you? Are you done yet? I got ONE more call for you.....
