    Need efficiency rating on Bard furnace

    Hi, I'm looking for the efficiency rating on a old Bard furnace from 83' I believe. Model No. IH60D36A it's a gas furnace. I was told it was 40% and another tech told me it was 70%. That's quite a difference. I can't find the info anywhere.

    From that year the 70% answer would be the correct one especially if it is just a builders grade system.
