Question DetailsAsked on 1/21/2016

cost for attic hvac system?

Our attic is currently finished however there is no HVAC ( old window unit). We would like to use the space more and would like to keep it cooled and heated year round. I was looking at split systems but they are costly ( bid for $8000) and was just wondering what is the best solution. Would a separate smaller furnace be more cost effective.

You would have to have it looked at by a Heating and A/C (your Search the List category) contractor. Might be your existing system could handle it if the attic living space were well and properly insulated, because the existing attic "floor" heating/cooling load from having an unconditioned attic would be eliminated.

Also - if that is not the case, a separate heat pump might handle both heating and cooling.

Everything depends on your climate, existing condiguration, how energy-efficient your house is now, what additional insulation you put around the living space in the attic, whether existing system were oversized a bit or not, etc. In many cases increasing insulation factor around the attic living space and on the existing floor left exposed outside the attic living spxace (like in the low-headroom eave area) can actually result in a lower total house heating and cooling load than what you have now.
