What Size Should My Replacement Furnace Be?

If it’s time for a replacement furnace or will be soon, the first step is to figure out what size of system will work best for your house. Having an accurately sized system is key to its efficiency and the comfort level of your home. With a little research, you’ll be able to find the perfect furnace for your needs.

When replacing your system, bigger isn’t always ideal.

You will waste a lot of energy and money if you choose a system that is bigger than you need. A system that is larger than you need won’t have to run as long, so it’ll be frequently cycling on and off, which causes extra wear on your system and can reduce the life of your system. An oversized system will not only cost more money up front, but it will cost you more over time as well. This is a decision you’ll want to stay away from.

Then there are the problems with a system that is smaller than you need. If your system is too small, it will run too often to try to heat your space, and it won’t be able to get the job done despite its work. A smaller than needed will work harder, which will decrease the system’s life span. Additionally, you’ll be paying higher energy bills for a home that’s not appropriately heated. Have a professional, like those at Precision Mechanical do a load calculation and chat with you on the best system for your replacement furnace needs.

How is Load Calculation Determined?

In the past, a home’s load calculation was determined based only on square footage. This method often lead to incorrect calculations. With advancements in technology and better knowledge, things are much more precise today. Your furnace professional will review your home as a whole, looking at things like its construction, the color of its roof and how well insulated it is. He or she will also consider the climate in Rapid City and how many individuals live in your home. This assessment is definitely much more thorough than providing a calculation based on square footage alone!

If your HVAC system is correctly sized it will keep you more comfortable and save on expenses. At Precision Mechanical, we understand that getting a replacement furnace is a big decision.
