My son had a Tempstar furnace installed in his house last year. He can't get temperature in his house over 65 degrees. I think his furnace is under sized. How can he determine whether or not it is the proper size for the house?

He has called the installer and they have not been very helpful. It has to be the furnace because his older furnace used to be able to keep the house at 72 F. Now he can only get house up to 69.

I think the installer undersized the furnace and doesn't want to admit it.

Due to the fact that there are many factors such as average winter temperatures, square footage, insulation and other things it's best to have a load calculation done by a reputable HVAC contractor.
