chenn49115 asks

I need to temporarily temporarily disconnect and move the our
outdoor central air unit so some foundation repair work can be done.
I'm a fairly competent DIY. Is a disconnect and reconnect something
best left to the pros? If it's something I can do myself where can I
learn the steps to do it? The owners manual is not available and the
small unit is about 12 years old.

May be quite costly to have the refrigerant lines
disconnected/evacuated and reconnected later.
Ona 12 yr old unit, may not be cost effective.

Would it be possible to create a "bridge" of heavy planking
underneath the unit and not move it at all?

I agree with Jim. The best bet is if you can avoid disconnecting at
all. If not, then you need a pro. The equipment and required
authorizations are not DIY thing anymore.

I did it myself over 35 years ago, but I would not do it today.

It would be against the law for you to do it yourself unless you obtain
a tech's license.

And also impossible to do legally even with a license without investing
in equipment which would cost you far more than having a licensed HVAC
tech do the job for you.

Be prepared to spend a few hundred bucks for the job, depending on where
you live.

This falls in the catigory of 'if you have to ask, then you probably can not
do it'.

The electrical part is nothing to it. The problem is the two lines carring
the refrigerant gas. YOu will have to have a machine that will suck the gas
out and store it so you can disconnect the lines. They are are under a lot
of pressure so you don't just unhook them. After you get ready to install
the lines you have to have a vacuum pump to suck out all the air and then
recharge it with the gas.

Someone mentioned the legal part. About 20 years ago the government decided
the refrigerant gas in most systems (especially the r-12 and r-22) was bad
for the ozone layer of the atmosphere. You can not just blow the old gas
out to the air but must recover it from the system. If you can not put it
back in then you have to take it to a place that will recover it. Big fine
if you do not do this.
