What is the difference between a highboy and lowboy furnace?
For the homeowner, the important distinction between the two is that the lowboy is shorter — typically around 4 feet in height. The lowboy can be installed in low-ceiling basements. A highboy furnace is typically around 6 feet in height. In case of a limited space, a downflow furnace can also be installed on its side.
What does a multi position furnace mean?
A multi-position furnace is provided that can be positioned for downflow operation, upflow operation, left horizontal flow operation, or right horizontal flow operation without major modifications in the field.
How does a down flow furnace work?
A downflow furnace takes in cold air at the top of the unit and expels air at the bottom. By doing this, the downflow furnace directs heat downwards towards the area that requires it. Heat naturally rises, so the downflow furnace must constantly fight against the natural tendency of the air it’s circulating.
How do you direct air flow from a furnace?
If you are looking at a furnace filter, find the arrow that indicates the proper air flow direction. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.

Why is one room colder than the rest?
If some rooms are warmer or colder than others, this is usually just a matter of balancing. Meaning adjusting the airflow to each room so they all even out. If a room is heating or cooling much quicker than other rooms, the airflow can be reduced to that room to even things out, also sending more air to other areas.
