What Size Should My Replacement Furnace Be?

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 figure out the size of system you’ll need? Selecting the best size is very important 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.

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

On the other hand, a system that is too small will stay on too long and can’t fully heat your home when the weather gets chilly. An incorrectly sized system will have to work harder, your energy costs may be higher and your comfort will be impacted because of that. It’s very important to speak with a pro that will do a load calculation and advise you on the right system for your needs.

How is Load Calculation Determined?

A home’s load calculation used to be calculated based only on square footage and was often erroneous. Technology and knowledge have made a lot of advances since then. When you’re ready for a replacement furnace, one of the pros from B & B Heating & Cooling will study your home as a whole and then be able to offer an accurate load calculation. Load calculations are made of everything from the construction of your home, amount of insulation, the local climate and type and color of your roof, to the number of home occupants – a truly comprehensive assessment of your needs.

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