A furnace is one of the largest investments you will ever make. Therefore, you will want to take extra time, energy, and steps to make sure you choose the right system. This can take some extra time as many aspects go into choosing a new furnace.

You need to think about what brand you want, what features are important to you, the needs of your family, the price, who you want to install it and more. One of the most important aspects to get right, however, is the size. The size of your furnace can affect the comfort of your home and the health of your HVAC system more than you may think.

When the Furnace is Too Small

If you are looking to save some extra cash when choosing a new furnace, you may choose a smaller model. This can actually cost you more in the long run, though. When your system is too small, you will find that it needs to run constantly to try and reach the temperature you set on your thermostat. No matter how much you turn up your thermostat, it may not be getting warm enough for your family to be comfortable.

The constant running will also take a toll on various components within your HVAC system. They will experience wear and tear much more quickly which can lead to frequent and costly repairs. Having a furnace that is too small will likely decrease the life expectancy of your system as well. If you think your system is too small, contact Modern Air Solutions for advice and potential solutions.

When the Furnace is Too Large

A furnace that is too large will give you the opposite problem of your furnace always running. Furnaces operate in cycles. They turn on and put out a certain amount of heat needed to reach the temperature you set on your thermostat. If your furnace is too large, it won’t take as long to put out the amount of heat it needs to reach your desired temperature. Therefore, your system will turn on and only run for a short period of time.

Your furnace uses the most energy during startup. When your system is constantly starting up and not running for an appropriate time, it wastes energy. Both a furnace that is too small or too large can cause your utility bills to rise unusually high. As with the small furnace, the constant starting up of a large furnace will also cause wear and tear to the parts faster leading to costly repairs and a shorter overall life expectancy.

Find the Right Size!

Furnaces use BTU’s or British Thermal Units per hour to measure the amount of thermal energy produced. One BTU will heat one pound of water by one degree Fahrenheit. When determining how many BTU’s your furnace will need, you should start by calculating the square footage of your home. Measure the length and width of each room, then multiply those numbers together.

This is a good start but is not all you will need to know. Many other factors can contribute the loss of warm or cool air in your home. This includes the amount of insulation, the quality and number of your windows and doors, how many levels your home is, the types of construction and more.
