Getting the right size furnace for your home is important. Oversized units will cost you more to purchase and run. Undersized units, however, might not be able to provide enough comfort through the dead of winter. How to get it just right?
In Nebraska, it is mandatory for new homes to have what is known as a “Manual J load calculation” to properly calculate heating and cooling loads. The heating and cooling load translates into the size, or capacity, of the new furnace needed in the home.
Older homes should also have a Manual J load calculation done for a replacement furnace, especially after any home performance measures such as air sealing or insulation have been completed. If your house was built more than 20 years ago, chances are the existing furnace was sized according to a vague “rule of thumb” rather than real data.
We have way better technology than a thumb nowadays for furnace sizing.
There are three types of furnaces on the market now:
Variable speed furnaces
A standard, or single stage furnace, has only one level of heat output and usually, the fan motor runs at only one speed. Single-stage furnaces run at the maximum capacity, regardless of the actual amount of heating needed.
A two-stage furnace has two levels of heat output: “Low” is for milder days, which can account for up to 80 percent of the heating demands in the year, and “High” is for the coldest winter days. A two-stage furnace runs for long periods at the low setting and provides even heat distribution.
A variable speed furnace has a fan motor that can move at different speeds to control the amount of heated air that reaches the living spaces. A variable speed fan allows you to have a small but constant airflow throughout your home, increasing comfort levels by controlling temperature and humidity and cleaning the air as it circulates through the filter.
All furnaces are tested for efficiency. The measurement that is most important to understand is Annual Fuel Usage Efficiency (AFUE). This indicates how efficiently a furnace can utilize the fuel it burns over a heating season. The higher the AFUE, the better!
