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.
