Furnace FAQ

How does a furnace work?

In a central heating and cooling system, a furnace burns fuel and distributes it throughout the house in conjunction with an air conditioner or heat pump.

What is two stage and modulating heating?

Two-stage heating means a furnace has two heating settings: high for the coldest days and a low setting for more mild temperatures. A multi-stage furnace is more efficient and keeps temperatures more consistent throughout the day.

How much does a new furnace cost?

American Standard furnace pricing depends on multiple factors like the size of your house, model, installation requirements—and even the climate conditions in your area. Average prices across the country can range from $1,600 to $6,000. Some furnaces even qualify for local rebates. Your best pricing resource is your local dealer.

What is AFUE?

Annual Fuel Utilization Efficiency (AFUE) is a measure of a gas furnace’s efficiency in converting fuel to energy. A higher AFUE means greater energy efficiency.

What size furnace do I need?

When it comes to choosing what size furnace you need, your best bet is to get a Manual J calculation done for your house. An HVAC expert can also recommend the correct size based on the square footage of your home. The maximum size unit you should buy would be 15% over the BTUs you need for cooling and 40% of the BTUs for heating.

What is the difference between a furnace and a heat pump?

A furnace burns fuel to create heat and distributes it throughout your home. It does not generate cold air. A heat pump uses the outside air to both heat a home in winter and cool it in summer.
