Electric Furnace Sizing Guide

A man works on a furnace.

It is critical to size your electric furnace to meet the needs of your home. There are many factors that need to be considered when choosing the proper furnace size. If you do not do thorough research and install a furnace unsuitable for your home, you may have uncomfortable living conditions as well as higher electric bills.

Size of Home

One of the main factors in selecting the proper electric furnace is the size of your home. Make sure that you contact a contractor to give you an idea on how your home size will affect your furnace size. You will find that there are several different furnace sizes; all will heat your home differently. Furnaces use the measurement of BTU (British Thermal Unit) per hour. The contractor will perform a calculation to determine the required BTUs for your home. Your BTU requirement will determine the minimum size furnace your home will need. There is no reason to upgrade the furnace size unless you plan on expanding your home in the future.

Weather Conditions

The weather conditions in the area that you live in will also help to determine the size of your furnace. If you live in an area that has mild winters, then you will not need a large furnace as compared to someone who lives in an area with severe winters. These conditions will be also be applied to the calculations to find your proper furnace capacity.

Home Structure

The overall structure of your home should also be considered. If your home is drafty or not well insulated, then a large furnace may be necessary. If you have a standard-sized home that is especially drafty, then you may want to consider getting a furnace that could better fit a larger home. Also consider if your home is very open or if there are several rooms. You will need to talk to a contractor about how the structure of your home could affect the size of the furnace that you choose. They will be able to tell you what to expect as far as getting a furnace that is right for you and your home.
