How to Determine What Capacity/Size of a Furnace You Need for Your Home

Published On November 4, 2018 | By Donald Llanas | home improvement

The size of the home matters when it comes to heating it. You will need a heating system that is going to be able to push out the heat as far as it needs to go.

By having too small of a furnace, it will not heat the places it needs to heat. You might have to worry about the furnace working overtime, causing the heating bills to rise and exerting too much stress on the furnace itself.

Having a larger furnace is not optimal either, because it is going to overheat the home and you may find that you also spend much more in your heating bills than necessary.

Having the most ideal size for the home that you live in is a must. Never have to worry about not being able to cover the square footage of the home with a furnace when you have the ability to choose whatever furnace you wish to go with.

What specifications to take into account

There are specific things that must be taken into account when choosing the right size furnace for your home. By having an idea of what to look for on the outside of the box, you can feel much more confident when using the furnace because you know not only is it going to do the job it needs too and heat the home, but it is also efficient at the same time.

The efficiency rating of the furnace needs to be taken into account because you want to make sure that you are using the right furnace that is not going to cost you too much to run in the end. When this is something that pops up on the box, make sure to read the efficiency level of the furnace and then go with the most efficient choice for the size that you need.

It is also good to consider the fact that the more efficient the furnace, the more it might cost up front. However, you will end up saving more money every month by using one of these furnaces over the others that may not be as efficient. It is important to consider the efficiency and weigh the up-front vs. the long-term costs.

Always remember that heat rises, so if you have more than one floor, take this into consideration. One of the best ways to help combat the issue of heat leaving the roof of the home is through the use of insulation throughout the home. It is also important to note that sometimes a smaller furnace might be needed for a two story because of this. It doesn’t always mean bigger if the home has two stories, since the heat will end up towards the top of the home anyway. But again, this depends on the insulation throughout the home.

What are BTUs?

BTU’s are British Thermal Units and it is a traditional measurement of heat that is used on almost all of the heating machines that are sold. It is the amount of heat that is required to raise the temperature in the space. It is used often in the United States alongside Fahrenheit.

Calculating the size of the furnace needed

There is a calculation that is used to determine the size of the furnace that may be needed for your home. Never have to worry about not being comfortable if you can figure out the size of the furnace on your own. Use this calculation method instead:

Know the square footage of the home before you go shopping for a furnace. This is very important. You do not have to include any of the rooms of the home that you don’t want to heat or cool.

Once this is done, then you want to multiply each square foot by 20 BTU. For example – if it is 1,000 square feet then you would do 20 BTU x 1,000 Square Feet which would give you 20,000.

Keep in mind that this is a minimum for a capacity, so you may need to add a bit more, but you have to make sure that the unit you choose is able to put out at least 20,000 BTU in order to efficiently and effectively run the heat in your home and make everyone comfortable.

Heating in specific zones

There are ways that heating is measured in specific zones throughout the country. This is because specific areas need more or less heat inside the home in order to make them comfortable. Specific areas may need 20 BTU’s, while others need closer to 50 or 60 BTU’s. The more warmer the climate you live in, the less BTUs needed, the more BTUs, the colder the climate is. The colder weather calls for a high capacity furnace than other areas throughout the country.

Always consult with a professional

It is important that you speak with someone that knows what they are doing when it comes to the furnace that you need to have put into your home. This is important because you don’t want to worry about not being able to choose the right furnace or worry about braving the winter with not enough heat. This is an important part of the home and without the right one, you either will be paying too much in your heating bills or having to worry about not having enough heat which again, might make those bills rise. Always consult with a professional that is easily able to provide more help overall.

If you are having a problem choosing the right furnace for your home, then it is important that you speak with a professional that is better able to help you with all that you need help with. Never have to worry about not being able to get heat when it is needed most. Contact professionals today. They will provide a free estimate and will be more than happy to direct you to the furnace and the size that is needed for your home based on a few specifications that are given.
