HOW TO
SELECT AN 80% EFFICIENT GAS FURNACE |

Estimating the Furnace Size |
 |
|
You can refer to an estimate or
proposal from a local contractor, refer to the size of your existing
system that you may want replaced, or use the sizing estimation
chart provided on this page.
Use the map to determine your
Region based on the location of your home. Using the equipment
charts, find your Region and go down the column to locate the
range that covers the Square Footage of your home. Follow the
row to the right to determine the recommended Furnace for your
application. |
|
NOTE: These tables and charts are
intended to be used as a guideline only. The information is based on
conventional window space (<15%), insulation and building
construction. Only use these tables as a reference. When including a
finished basement, use 1/2 of the finished basement square footage
with the rest of the area being calculated. |
