These offer two possible configurations.
Horizontal gas furnace in attic.
The horizontal furnace installation in an attic should be on a service platform large enough to allow for proper clearances on all sides and service access to the front of the furnace see figure 5 clearance table.
Buy horizontal gas fired furnace direct and save.
Horizontal gas furnace superstore.
Horizontal installation is also available for some furnace and air handler models.
Expect to pay around 1 000 for the equipment along with another 1 000 to install it for most geographic locations.
Horizontal flow systems are most often installed in attics and crawl spaces where space is limited due to a low ceiling and a standard upflow or downflow furnace just won t fit.
Upflow horizontal and downflow horizontal models are also available.
Most furnaces draw cold air in at the bottom and warm air is released out the top.
In certain situations this is not practical and a counterflow or downflow furnace is needed.
For instance in a basement crawl space or attic.
The cost profile for a furnace in the attic is competitive.
If you want to purchase a mid efficiency furnace for your home then the price profile for the equipment is similar with a downflow model compared to an upflow one.
