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.

Yesterday, I noticed that the clicking sound corresponded to an
indicator light on my thermostat. The light is labeled "Aux Heat", and
when the heater is clicking away, the light is blinking away, turning
off every time the heater clicks. I have electric heat, and right now
on the thermostat, the fan is set to Auto (as opposed to On) and the
System is set to Heat (as opposed to Off, Cool, or Emer). Since I
noticed the clicking/blinking relationship, I've checked the light when
the heater has been running quietly, and I've seen the light both
steadily off and steadily on.

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?

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.

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.

"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.

Sounds like a problem we had. The relays for the auxillary heat are
going bad (or the contacts are dirty) and this is causing the chatter as
it keeps trying to lock on. Aux heat will be used during the defrost
cycle of the heat pump. This is a normal operation that happens every
so often (some pumps have timers, some have sensors to detect frost
buildup).

You need to have a heat pump specialist check the relays and either
clean or replace them. At the same time he can determne if this IS
really normal or if there is something else wrong.
