What Size Should My Replacement Furnace Be?

What Size Should My Replacement Furnace Be?

You’ve found yourself the point where it’s time for a furnace replacement or perhaps you see this point rapidly approaching, but how do you figure out the size of system you’ll need? Picking the correct 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.

Buying a system that is too large wastes energy and money. A larger system will constantly be warming up and cooling down because it’s production will not require it to operateas long. This is known as “short cycling” and it increases the wear on your system and in turn reduces the life of your system. An oversized system will cost you more money up front and in the long run.

On the other hand, a system that is too little will operate 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 expenses may be higher and your comfort will be affected because of that. It’s very important to speak with a pro that will complete a load calculation and advise you on the correct 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 come a long way since then. When you’re ready for a replacement furnace, one of the experts from O'Brien Heating & Air Conditioning will study your home as a whole and then be able to provide an accurate load calculation. Load calculations include 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 all-encompassing assessment of your needs.

A properly sized and functioning HVAC system will not only keep you more comfortable, it can also save you money. Buying a replacement furnace is a huge decision, which is why we want to make sure your system will meet or exceed all of your needs. We are here to help you along throughout the process.
