The furnace size you choose for your heating and cooling needs will depend on how much space you are attempting to heat. You want to choose one that will service your home and keep you toasty during the winter months, and cool during the hotter days of summer. You will also want to consider the area or climate where you live. You may also need to consider if you have different levels in your home below the ground levels, such as in some office buildings.
Correctly identifying what size furnace and air conditioning system your home needs will depend on the amount of BTUs (British Thermal Units) of the furnace. The amount of time it will take to heat one pound (0.454 kg) of water one degree of Fahrenheit is measured in BTUs. This calculation is extremely important to effectively cover the square footage in your home. If you own your home, the footage will be listed in the property assessment. As a general rule for a mild climate, you will need approximately 30 BTUs of heat per square foot. In a colder area, you may need as much as 60 BTUs per square foot.
Remember the manufacturers of furnaces will list the efficiency rating on the furnace. You want to find one that has at least an 85% to 90% efficiency rating.
To receive heating efficiency, you will want a system that suits your home. If the unit is too large, you may waste energy because the cycle is continuously cooling down or warming up. If the furnace is too small, it will not effectively cool or heat the house. The unit would have to run almost all of the time.
It may be a good idea to have a professional to give you an estimate if you are unsure of the math calculations. Some businesses offer an online solution for your needs. The service company should provide the exact figure needed to keep your home comfortable year-round.
If your home is similar to one in the neighborhood, you could ask those homeowners to see what size unit is used in that home.
