What type of a/c system should I get?

I have Carrier furnace 58sta070 in my house but no a/c. I was wondering if I can buy evaporator coil by itself or would I need a whole new system. Also what brands are the best?

One of the HVAC pros should be along. In the meantime, if you could post your location and a few basics about the house, that may come in handy in an answer.

No such thing as a best brand.
You’ll need a matching condenser and evaporator.
You’ll need to start by doing a manual J to determine what size unit you need. Then a duct evaluation to determine if you can move enough air for that size.
The standard calculation is 350-400 CFM per ton of capacity.
Houses with heat only are notorious for undersized duct compared with cooling requirements.

The blower has to have sufficient capacity as well as ducts.

A lot of old houses don't have ceiling level second floor return and have it warm upstairs as a result.

I agree with that 100%. My own home is like that.

Call a few pros and get some free estimates.
The furnace is convertible but the duct work can be a stumbling block.
