What Size Should My Replacement Furnace Be?

You’ve reached the point where it’s time for a furnace replacement or perhaps you see this point approaching quickly, but how do you decide the size of system you’ll need? Picking the best size is critical for your system’s efficiency and your home’s comfort. There’s a perfect furnace out there for you and your home’s needs.

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

Installing a system that is too large wastes energy and money. A larger system will continuously be warming up and cooling down because it’s output will not require it to operateas long. This is known as “short cycling” and it increases the wear on your system and in turn hurts the lifespan of your system. An oversized unit will cost you more money up front and over time.

On the other hand, a system that is undersized will run too long and won’t be able to fully heat your home when the weather gets frigid. An improperly sized system will have to work harder, your energy costs could be higher and your comfort will be affected because of that. It’s very important to talk to a professional that will perform a load calculation and advise you on the best system for your needs.

How is Load Calculation Determined?

A home’s load calculation used to be calculated based solely on square footage and was often erroneous. Technology and knowledge have come a long way since then. When you’re ready for a replacement furnace, one of the pros from Thurston Heating & Air Conditioning will study your home as a whole and then be able to provide an accurate load calculation. Load calculations are composed of everything from the construction of your home, amount of insulation, the local climate in addition to type and color of your roof, to the number of home occupants – a truly all-encompassing assessment of your needs.

A correctly sized and functioning HVAC system will not only keep you more comfortable, it can also save you money.
