My power is back but the furnace isn't running. Why?
Some furnaces need a reset after power loss, or a breaker may have tripped. Try the service switch off and on once; if it still will not run, call.
How do I know it's the flame sensor?
If the burners light for a few seconds and then go out, and this repeats, a dirty flame sensor is the most likely cause.
Why is my older house's furnace so loud?
Undersized ducts and returns force the blower to work against high resistance, which is noisy and hard on the equipment. A technician can measure static pressure.
Is steam from my heat pump normal?
Yes, during defrost cycles. Constant ice is not.
How often should a furnace be serviced?
Once a year, ideally before the heating season.
