How to Properly Size a Gas Furnace for Your Monmouth Home

If it’s time to upgrade your home’s gas furnace, don’t assume that it’s a matter of simply choosing a brand, and having its capacity matched to your home’s square footage.

When it’s time to size a gas furnace, you’ll want to work with a trained professional HVAC installer who has the experience and technical know-how to get it right. While a homeowner can attempt to size a gas furnace, the risk of oversizing or undersizing will be significant.

Getting Furnace Size Right

A natural gas furnace that’s too small will struggle to heat your home during the colder months, causing it to overwork. In contrast, a furnace that’s oversized will run for short periods of time, then shut down, repeating this cycle over and over again during operation. This “short-cycling” will result in wasted energy, increased stress on the furnace blower, as well as uneven air distribution and inadequate air filtration.

Using Outmoded Sizing Methods Doesn’t Work

Properly sizing a residential gas furnace takes into account many more factors than the cubic footage of your home and mimicking the size of your previous furnace. In the latter instance, the furnace you’re replacing may not have been sized correctly, or perhaps, you’ve undertaken energy-efficiency upgrades in your home (more insulation and better air sealing) since your furnace was installed.

Qualified HVAC contractors now use high-tech procedures for sizing furnaces. They use the Air Conditioning Contractors of America (ACCA)’s load calculation software, Manual J, to calculate your home’s heating load before recommending the right furnace size.

This takes into account a multitude of factors, including your home’s size and layout, airtightness, insulation, window location, number of home occupants, their temperature preferences and much more. This way, the furnace that’s recommended for your New Jersey home will be precisely matched to fit your living space.
