Wholesale Furnaces Buying Guide

Gas furnaces use gas to heat your home. In order to find the perfect furnace for your space, you will first need to calculate the square footage of your home in order to estimate how many BTUs the furnace will need to possess, whether you want standard or high efficiency, and what orientation the furnace will need to be.

Here is how to find the proper tonnage for your gas furnace:

Warmest climates: 30-35 BTUs per square foot

Warm climates: 35-40 BTUs per square foot

Mild climates: 40-45 BTUs per square foot

Cold climates: 45-50 BTUs per square foot

Coldest climates: 50-60 BTUs per square foot

You’ll need to decide which orientation you’d like to choose for your gas furnace. We offer downflow horizontal or upflow horizontal models. Upflow furnaces are often installed in the basement or in the closet, where the ductwork is located above the level of installation. Contrarily, downflow systems are installed in crawl spaces or in areas where the ductwork is below the level of installation.

You also have the option to choose between a “standard efficiency” gas furnace system or a “high efficiency” gas furnace system. On our site, “standard efficiency” stands for gas furnace systems that are 80% efficient and “high efficiency” gas furnace systems are those that are 92% efficiency or higher.

Disclaimer: Before making a purchase, you should always check first with your qualified installer to figure out what unit is best for your home or space.
