I just bought a condo (woohoo!), and have noticed ever since I
moved in that the heater will sometimes have a "clicking fit" -
for no reason immediately apparent to me, the heater will make a
clicking noise every second or so, and this will last for quite
some time, often until the heater turns off. Then again,
sometimes (like right now) the heater happily trucks along,
warming me & my dogs without making any irritating noises.

You likely have a heat pump in your heating/cooling unit.
A heat pump can only get so much heat out of the environment
during the winter. For those really cold days, the heat
pump needs help from a conventional furnace. What is happening
is that this furnace kicks in in Aux mode.

In your case, this Aux mode furance is apparently not starting
properly. Each click is a retry for it to ignite. That ignition
is not working most of the time.

"Ignite"? on a heat pump system ? Not likely. It is more like the
click is a relay opening and closing turning the AUX on and off. This
should not happen at ths frequency.

I dumb giess might be the anticipatory feature which typically
"anticipates" the current conditions and whether or not the AUX needs
to be turned on to boost heating.

This last guess is not based upon anthing other than what the HVAC guy
has told me.


I've never owned my own place before, and never had electric
heat in any of my previous homes. Is this normal operation, or a
symptom of a problem?

Not normal. You need to get a heating contractor out to
service the unit. Check on the unit for any stickers with
the name & phone number of who put it in or last worked
on it. Your building manager may also have some suggestions
on who to call. Finally, your city gas company might work
on these units, and allow you to put the bill on with your
utilities.

You do want to get this fixed. When aux mode is selected,
that means that your heat pump is working in an mode where
it is very inefficient, which likely is running up your
utility bills.
