By the way, since we're on the topic, what does the built-in GFI
protector do? Should I have the outlets changed to one with GFI
protection, but they are single dedicted line outlets. Is it really
that important.

Details are posted by trader4. To summarize what he has posted:
GFCI is for human protection; not for air conditioner protection.

Next month means live Christmas trees. From another's personal
experience, if a Christmas tree catches fire, you have 5 minutes to
empty the house. In that Christmas tree fire, humans barely escaped;
all pets were killed.

Another electrical protection device is called an AGFI. This is a
GFI now required for all bedrooms. It detects electric arcing; cuts
off power before a fire can occur. In that example, the wife saw
sparks ignite the tree when she powered on its lights. That arcing
would have been quashed by an AGFI. IOW the circuit that powers a
live Christmas tree should have an Arc Fault Detecting Ground Fault
Interrupter. A newer type of GFCI that also quashes electrical arcs.
Available in any electrical supply or hardware store. Unfortunately I
have never found a plug-in version - and don't know why. Even GFCIs
are found on some extension cords - especially those used by plumbers.

AGFIs are required on all bedroom circuits after 2002. But
experience demonstrates why an AGFI is strongly recommended for the
circuit that powers a Christmas tree. Again, its purpose is to
protect humans.
