Clicking sound on 10 year old outside Heat Pump unit
I have just noticed a clicking sound coming from the outside unit of my AC/Heat Pump. I looked through the forum, but haven't found something that helps. I just want to see if this is cause for concern.
Details..
American Standard Inc
The Trane Co
Mnfc date 4/91
Model Number TWN724B100A0
I have a big fan unit outside and I have other stuff (technical term) in the attic.
Just noticed ticking today, but I don't know how long it's been doing it.
It's been much colder than normal so we've been running the heat harder, but the last 3 or 4 days have been fairly nice and we haven't run heat or air (in florida).
I don't know what the efficiency of the unit is.
Thanks in advance for any help.
