I raise this question because I want to help a friend of mine who is troubled in purchasing for a new home furnace. She already asked my opinion and told her that it would be better if she purchase a home furnace that is suitable to the size of her home to ensure the indoor air quality circulation. She also consider her budget, but she want to have a home furnace that has the best brand. Which do you would be best for her?
Thanks in advance, I know that I can find resourceful information from the group.
