Two-stage furnaces are a little smarter and more complex than their single-stage counterparts. Instead of just a basic on\/off switch, two-stage furnaces have two \u201con\u201d settings: high-fire and low-fire. The high-fire setting kicks on when a lot of heat is needed and low-fire kicks on when less is needed. Many two-stage furnaces also have multi-speed or variable speed blowers that distribute varying levels of air through the ducts. All in all, they\u2019re better than single-stage furnaces at keeping a consistent air temperature.<\/p>\n

Mid-efficiency, two-stage furnaces costs about $2,500 to $4,000<\/strong>, including installation. The furnace itself usually costs $1,500 to $2,000<\/strong>, while labor adds an additional $1,000 to $2,000<\/strong>. High-efficiency models cost about $4,000 to $5,000<\/strong> to buy and install.<\/p>\n Generally, two-stage furnaces cost about $500<\/strong> more than comparable single-stage models. Opting for a variable-speed blower adds about another $200<\/strong>. For example, a brand that sells a high-efficiency, single-stage furnace for $3,700 <\/strong>would likely sell a high-efficiency, double-stage furnace for $4,200<\/strong> and a high-efficiency, double-stage furnace with variable speeds for $4,400<\/strong>.<\/p>\n

\n <\/ul>\n Chances are, you\u2019ve had a single-stage furnace in your home at some point. The technology is older and simpler than two-stage furnaces.One-stage furnaces have a simple on\/off switches that controls the heat. They\u2019re either blasting heat at full force or not running at all. The furnace waits for the house to get cold (sometimes too cold) before kicking on. Then it pumps the house full of heat (sometimes too much heat) before the thermostat tells it to shut down.<\/p>\n Mid-efficiency, single-stage furnaces costs about $2,000 to $3,500<\/strong>, including installation. The furnace itself usually costs $1,000 to $1,500<\/strong>, while labor adds an additional $1,000 to $2,000<\/strong>. High-efficiency models can cost $4,000<\/strong> or more to buy and install.<\/p>\n

\n <\/ul>\n Single-stage or double stage is far from the only decision you\u2019ll have to make when purchasing a furnace. You\u2019ll have to decide on fuel type – natural gas, propane, oil or electric – as well as size (heat output) and the energy efficiency rating. <\/p>\n Fuel type is often determined by the type of furnace you have now. If you have an electric furnace and there is no gas line running to your home, chances are it won\u2019t be cost effective to switch. However, natural gas is typically less expensive than oil, and both tend to be less expensive than electricity. <\/p>\n Energy efficiency is measured by annual fuel utilization efficiency (AFUE). If a furnace has an AFUE of 80, that means 80 percent of the fuel is converted to heat while the other 20 percent is lost. For gas- and oil-fueled furnaces, the lowest efficiency rating allowed by federal rules is 78 percent (except in mobile homes, where the minimum is 75 percent). High efficiency units have an AFUE of 85 percent or greater. Electric furnaces are always highly efficient; it\u2019s just that electricity is a more expensive heating method than gas or oil. <\/p>\n Heat output is measured in British thermal units (BTUs). Common heat outputs include 40,000, 60,000, 80,000, 100,000 and 120,000 BTUs. The appropriate heat output is directly related to the size of your home – there\u2019s only one number that works for each home. A furnace that is too large will not be energy efficient; one that is too small won\u2019t provide enough heat. Consult a professional to find out which heat output is appropriate for your home.<\/p>\nTwo-Stage Furnace Pros <\/h4>\n
