AC wired with 2 120 Breakers

Our house was built in 1964 and we purchased in 1997. According to the plans it has had central AC since it was built. But while adding a dedicated circuit for a built in microwave I noticed that there were only

2 240 circuits in the breaker box. 1 = Dryer 2 = Range. None for the AC. Then I noticed that one breaker was labeled Furnace (20A) and the one below it was labeled Air Conditioning (30A). Then I check at the compressor it has 240v and tripping either breaker it drops to 0v. Is there any reason this should be 2 separate 120v breakers? If I replace it with 1 breaker would it be a 20A or 30A? I haven't looked at the furnace yet as it's hard to get to (I'm assuming it's 240v also but it's natural gas so I suppose it could be 120v).

gas furnace will most likely be 120v on a single pole breaker, however having 2 seperate single pole breakers for the A/C is not only a safety hazard, but can also be a FIRE hazard. GET IT FIXED ASAP!!!
