Single-Stage Furnaces - 95% AFUE
Single-stage output, multiple blower speeds: Achieve better temperature control and energy savings.
Relax in a comfortable space and have peace of mind that Durastar’s single-stage furnaces – 95% AFUE – blanket you with warmth and protect your wallet. Get better control with two aluminized steel heat exchangers that work together to automatically adjust blower speeds and extract the most out of your fuel bill. If outdoor conditions are frigid then the blower kicks into HIGH gear to keep your indoor spaces comfortable. Alternatively, when the weather is mild, the furnace blower drops to LOW power, therefore using less energy to maintain the desired temperature.
These single-stage furnaces – 95% AFUE are multi-positional and adapt to fit your home’s existing ductwork. Equipped with a multi-speed, constant torque ECM motor you obtain steady, reliable airflow year after year. To thoroughly review your heating options, be sure to visit our complete collection of Core Series and Advanced Series furnaces. Depend on Durastar for highly tested heating and cooling systems.

Frequently Asked questions
What is AFUE?
Annual Fuel Utilization Efficiency (AFUE), is a standardized measure of efficiency for how furnaces and boilers convert energy to useable heat.
What is the main difference between a furnace and a heat pump?
Furnaces burn fuel to generate heat whereas a heat pump draws air from outdoors across the condenser coil, either releasing heat to the outdoor air when in cooling mode or absorbing heat from the outdoors, even in the coldest weather in heating mode.
How often should my furnace be serviced?
Durastar recommends your furnace to be serviced at least once a year to ensure it is functioning optimally and providing maximum comfort.
Do gas valve stages make my furnace more efficient?
Yes, in contrast to a single-stage gas valve, two-stage valves adjust their output to obtain your desired indoor temperature. That means if it is a milder day, then your system will use less energy to achieve maximum comfort. Less energy output often results in lower utility bills.
What is an HVAC evaporator coil?
Evaporator coils are located inside your home and work with your air conditioner and furnace. Depending on whether you are heating or cooling a space, the coils pull in existing air to cool it or they add heat to warm it up. In essence, coils are one of the most important pieces to your HVAC system and are responsible for the heat exchange.
What is the benefit of an all-aluminum coil?
Unlike copper which may rust over time, all-aluminum coils do not. In addition, they are more resistant to micro-leaks which increases the longevity and efficiency of your unit.
What is the difference between an 'A' coil and 'N' coil?
‘A’ coils are formed using two slabs of fins – these types of coils have a surface area similar to a slab coil, however, they are installed without transition ducting. Alternatively, ‘N’ coils use three fin slabs. This arrangement increases the coil’s surface area and, therefore, accommodates more refrigerant. As a result, it operates more efficiently and generates more heat.
