Like many things, there are multiple options for furnaces. Some things to consider when choosing a furnace:
AFUE Rating: The higher the rating, the more efficient the unit is.
Variable Speed Blowers: This can deliver air slower (while often making less noise) when less heat is needed. That produces fewer drafts and uneven temperatures throughout your home. Variable speed furnaces are considered more efficient.
Modulating Furnaces: Available on furnaces that have a variable speed blower, this feature can increase efficiency and comfort by automatically varying the amount of heat the furnace delivers, usually between multiple heating levels. The furnace can thus deliver heat more continuously than one with a fixed heat output.
Ignition System: Fewer furnaces have a pilot light these days- a flame that burns continuously, awaiting the next command to ignite the burners. Furnaces with intermittent, direct spark or hot surface ignition do away with the constant pilot light in various ways. That increases efficiency and is usually reflected in a furnace's higher AFUE rating.
Dual Heat Exchanger: Heat exchangers are the components that draw heat from the burned gas. To draw more heat from the air they burn, energy efficient furnaces supplement the primary heat exchanger with a second heat exchanger. Because the exhaust gases in that second exchanger might yield a corrosive acidic condensate, the second exchanger is made of stainless steel, lined with plastic or otherwise protected.
Air Handlers are sometimes referred to as electric forced air furnace or electric furnace. The major difference between a furnace and an air handler is that the furnace uses gas and the air handler is totally electric. When replacing your air handler, it is recommended to choose a higher SEER rating. The higher the SEER rating, the more efficient.

When you think about cooling, you probably don't think of heat pumps. In fact, the words "air conditioner" is probably what you think. A heat pump can both heat and cool, and in some applications, it's preferred to separate heating and cooling systems. Heat pumps are typically used to pull heat out of the air or ground to heat a home or office building, but they can be reversed to cool a building. Heat pumps and air conditioners operate in a very similar way. One of the biggest advantages of a heat pump installation over a standard (HVAC) heating and air conditioning unit is that there's no need to install separate systems to heat and cool your home. Heat pumps also work extremely efficiently, because they simply transfer heat, rather than burn fuel to create it. This makes them a little more green than a gas burning furnace. They work best in moderate climates, so if you don't experience extreme heat and cold weather, then using a heat pump instead of a furnace and air conditioner could help you save a little money each month.
