Your furnace keeps your home from being infiltrated by freezing temperatures during the cold, stark, winter months. The modern furnace is a complex piece of technology that increases your home’s energy efficiency and maximizes your comfort. Properly installed furnaces will keep you warm for years with little trouble or maintenance.

Kinds of Furnace
Presidential Heating & Air Conditioning works with a variety of furnaces, providing expert installation you can rely on.
There are two primary categories under which all modern gas furnaces fall: conventional furnaces and condenser furnaces. With a conventional furnace, natural gas is ferried to a burner located within a combustion chamber, where the gas is then mixed with air and ignited by a pilot light. A condensing furnace works similarly to a conventional furnace but has the added feature of a sealed combustion area, allowing a second heat exchanger to extract extra heat from the created water vapor.
Both conventional furnaces and condensing furnaces are available in three different stages, each determined by the operation of the blower and burner. These include:
- Single-stage Furnace: this single-setting blower and burner provides a continuous level of heated air
- Dual-stage Furnace: this dual stage furnace allows you to alternate heat generation between “high” and “low”
- Modulating Furnace: sophisticated controls that can be raised or lowered in small increments, allowing for the greatest control of temperature
Selecting a New Furnace
Understanding the power and size of the furnace needed to best perform in your home is vital. A too-small furnace may run constantly, using more electricity than is required, dramatically increasing your energy costs. A too-large furnace may fluctuate constantly, performing short cycles and turning on and off frequently, excessively wearing internal components.
Natural gas is most commonly used to power a modern-day furnace: it is energy-efficient, decreasing your energy costs and decreasing its impact on the environment. Other options for your furnace include coal, electric, wood, and oil.
The efficiency of different models of furnaces are established by measuring the Annual Fuel Utilization Efficiency, or AFUE. The AFUE measures how well fuel is converted to energy: the higher the rating, the more effectively the furnace functions. All furnaces must have an AFUE rating of 78 percent or higher. The different classes of furnace available for use today, based on AFUE, include:
- Low-efficiency Furnace AFUE Rating: 78%
- Mid-efficiency Furnace AFUE Rating: 80-82%
- High-efficiency Furnace AFUE Rating: can reach up to 97%. These models are also Energy-Star approved.
