Furnaces

As a homeowner, you'll encounter numerous difficult decisions, and one of the most crucial ones revolves around deciding when it's time to replace your furnace. If you've been researching online or stumbled upon discussions regarding variable speed heating, single-stage, two-stage, and modulating gas valves, as well as AFUE ratings, we are here to help. Allow us to provide you with explanations for these furnace systems and relevant terminology, aiding you in better understanding your options.

Furnace Efficiency Rating AFUE

The annual fuel utilization efficiency (AFUE) is a metric used to gauge the efficiency of modern furnaces. It is determined by comparing the furnace's annual heat output to its total consumption of fossil fuels. For instance, a furnace with a 99 AFUE rating delivers 99 cents worth of heat for every dollar spent, with only 1 cent being lost. It is important to note that the AFUE rating does not account for heat loss that may occur through the ducts.

Variable Capacity Furnaces (Modulating Gas Furnaces)

A variable capacity furnace, also known as a modulating gas furnace, is an advanced type of heating system that adjusts its output between 35% and 100% depending on the heating demand. This allows it to use only the amount of fuel necessary to maintain the desired temperature. These furnaces are among the most energy-efficient on the market, with an efficiency rating of 99%.

Two Stage Furnace

A two-stage furnace has two heat output levels, one for mild and one for cold weather. It saves energy and reduces noise by running at a lower speed during mild weather, and provides more heat during cold days by running at total capacity. This leads to energy savings and better comfort. Though it has a higher initial cost, it saves on monthly heating bills.

The Variable Speed Furnace Blower

A variable-speed furnace employs a blower motor with adjustable speeds to regulate the airflow within the furnace. This enables the furnace to modify the fan's pace according to the heating requirements, leading to enhanced temperature regulation, better indoor air quality, consistent temperatures, and a reduction in the frequency of furnace cycling. As a result, this system is more energy-efficient and economical compared to conventional furnaces with fixed-speed blowers.

Single Stage Furnaces

The single-stage furnace is the most basic and affordable option among all types of furnaces. It is also the simplest in terms of technology. However, this simplicity comes at the cost of energy efficiency, resulting in higher monthly utility bills. This is because a single-stage furnace uses the same flame size to produce heat, regardless of the temperature inside or outside.
