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.
