One point about a 90 in the attic in a cold climate is if the proper steps are not taken you can freeze a condensate line up there. If it s less than 90 percent it will be less efficient.

If an attic installation is possible in your home it can be a great option for many homeowners. Attics though ventilated with outside air tend to stay a fair bit warmer than the outside. Most of the issues that furnace might experience in an attic are due to extremely cold weather in this poorly insulated space.
