Thanks for the reply.

I have thermostat with battery backup, but have not seen any low battery
messages. Furthermore I changed batteries each year June 1, so that cannot
be the problem.

Regarding the other 2 suggestions to check out, can a tech determine if they
are a problem if the compressor is currently working? If not, should I just
wait for house to heat up again, see that the air handler is working and
compressor is not working, and then wait for a service tech?

I have an 8 yr old house and A/C system. That is my current problem,

I will be leaving for an extended vacation soon, and am very concerned
that
the A/C could shut down while we are away form southern Florida.

About a month ago, we came home one day and it was 80 degrees in house,
so I
knew A/C had a problem. Furnace was running, but compressor was not.
Called A/C service and they said to shut off furnace. When tech got
there
next day, and turned on furnace, compressor went on OK. They checked
every
thing out and it all seemed to be OK. Since it was all running, there
was
nothing else to do.

Had A/C service with annual tune-up, and tech said all was OK last
Wednesday. Today, just got home, and it was 79 degrees in house.
Furnace
was on, but compressor was not. I shut down furnace for an hour and
turned
it on. This time compressor was on. I will call A/C service company to
check out system, but I am concerned that they if system still working,
there is nothing for them to do.

Anyone have a similar problem with a problem such as this? Any
suggestions??


There are lots of possibilities. Here are some to start the list:

Battery operated thermostat with weak batteries

Weak motor relay or starting capacitor on compressor

Failing/overheating compressor

You (or someone you hire) will need to methodically eliminate
these and other possibilities.
