What Size Furnace Do I Need? It Depends on a Few Factors
There are a few things to consider when asking yourself what size furnace you need. Each one of the following factors can have a major impact on how well your furnace heats your home. Most of these aspects will be calculated and determined by an HVAC technician, but we believe it is good for customers to stay informed.
Here are some things to consider when asking “What size furnace do I need?”:
- Square Footage – The square footage of your home will help to determine the best sized furnace for your needs. The larger the square footage, the more heating power that is required.
- Windows – When people ask us “What size furnace do I need?”, many people are surprised when we ask how many windows they have. Having lots of windows can affect the heating of their homes. Heat escapes through the panes of windows, so the more windows you have, the less efficient your system may be. The quality and age of your windows will also come into play. Older or less efficient windows will lose more heat, while newer, energy efficient windows are much better at keeping heat in.
- Age of House – A newer home will generally be better insulated than an older one, which means that it stays warmer for longer. This factor can influence the size of furnace your home needs. Additionally, older homes can sometimes upgrade their insulation to boost heating efficiency.
BTUs and Furnace Sizes
BTU stands for British Thermal Unit and is a measurement of heat that is used when determining the heat output of a furnace or heating system. The higher a furnace’s BTU rating, the more heat it can put out. While it can be tempting to simply see a high BTU rating and assume it is the best, it is important to remember the size calculation. An HVAC technician will use the equation of square footage x 45-50 BTUs. This will show them the ideal BTU output for your home.
