The heat has motivated me to have central air installed at my home. I am
trying to avoid getting ripped off on the electrical part of the job.
My understanding is that central air conditioning units generally pull
about 30 amps, depending on the size. At any rate, when I look at my
electrical service box, there are two 20 amp breakers that are unused.
Is it easy to somehow combine these two to support the needs of the
central air? Should the contractor that installs the AC be able to
handle this as a standard part of the job, or am I looking at additional
The installer will most likely remove one or both of the 20 amp
breakers, and put in a double pole 20 if you're getting 2 tons, and a
double 30 for 2.5 tons.
I can't comment on your part of the world, but the company I work for
does this kind of work on a regular basis, and it isn't an add on
cost. There are other factors which are much more important than a
couple breaker slots in your electric box.

You can\'t shout down a troll.
simple answer to you is NO you can not combine,
however? yes you can change circuit breaker to higher amperage,
that is? If you main source main supply can handle it,
your contractor should be able tell you that.
Bit of advice don't cheat on power supply and
specially if you are in area where power is always
some what low to start with.
good luck from Dido
