Electrical question

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 expenses?Thanks.
