What Size Should My Replacement Furnace Be?

If it’s time for a replacement furnace or will be in the near future, you will need to determine 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 select the perfect furnace for your needs.

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

Your home will waste a lot of energy and money if you pick a system that is too large. A system that is too large 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 lessen the life of your system. An oversized system will not only cost additional money up front, but it will cost you more over time as well. This is a choice you’ll want to avoid.

Then there are the challenges with a system that is smaller than necessary. If your system is too small, it will run more frequently to try to heat your space, and it won’t be able to get the job done despite its effort. A system that is too small will work harder, which will shorten the system’s life span. Also, you’ll be paying higher heating bills for a home that’s not adequately heated. Have a professional, like those at Three Rivers Heating & Cooling perform 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 figured based only on square footage. This method typically lead to inaccurate calculations. With advancements in technology and improved knowledge, things are much more precise today. Your furnace professional will examine 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 think about the climate in Portland and the number of people live in your home. This assessment is certainly much more thorough than determining a calculation based on square footage alone!

If your HVAC system is appropriately sized it will keep you more comfortable and save you money. At Three Rivers Heating & Cooling, we understand that buying a replacement furnace is a huge decision.
