Question about Carrier 38CKC060 Air Conditioner
The unit is a 3 ton, 10 SEER, but I'm not sure if it uses the R410A, the sticker is off the condenser, there is no where to look, it was purchased by the previous homeowner. One tech said R22 one tech said R410A, who's right?
Its r22 refrigerant.

Hello, There are a few ways to tell, you csn usually find out by the compressors model # or they have a tool that is called a refrigerant " identifier" on the market.

That is a fairly large difference. It is usually ok to have the inside evap. coil and blower up to 1 ton larger than the outside condenser. That will make the unit slightly more efficient as well as less likely to freeze up on low airflow situations. It is not recommended to install a new condenser on an old evap coil. There has been a lot of changes to the design of the coils in the last little while. For example a 10 year old 2 ton coil may only have 3 cubic feet of volume but a new 2 ton coil may have 4 cubit feet of volume.
There are many factors that may have infulenced the decision on what size condenser to install. Many of which can only be done by visiting the home and doing alot of work, checking the duct sizing bioth supply and return, inspecting the insulation and windows of the home etc. etc. Most of the time that never gets done. You can blame the contractor for not doing a complete check, but at the same time you can blame the customer because many contractors that are that good loose the job to a cheaper bid that did not no any of the research. It is a catch 22 for everyone involved.
There is ALOT more to sizing equipment that many people think, sadly that also includes many HVAC contractors. Way too many people use "rule of thumbs" or flat out "guess".
Sorry for the rant but your queston can only be answered by a good well educated HVAC contractor visiting your home. That type of a contractor is getting hard to find these days in such a price competetive world.

Don't even think about it. This is an industry where you get what you pay for most of the time. Is your system not working currently? If there is a guy willing to install a system you bought off the internet he doesn't belong in this industry. I have gone behind people like that and had to explain to a homeowner how someone did a complete botch on their job and I have to rip it all out and start over. BE VERY CAREFUL if you want to try that. A company's price is usually a reflection of their quality and level of service. When was the last time you ever got anything of the highest quality for the cheapest price?

First off - the 'rule of thumb' is 600' per ton of Air Conditioning. In other words your old unit is a 2 ton unit. So - 2 tons x 600' = 1200'. As you can see if you install the 2.5 ton unit - you will be installing a AC that 'could' cool a 1500 sq ft house (2.5 x 600' =1500 sq ft.). Slightly more than what you need; and the 3.5 ton unit is 'way to big,' (3.5 x 600' = 2100 sq ft.).
Note: fyi - many in the AC business will sometimes refer to tonnage in btu's, i.e. 1 ton = 12000 btu - hence a '2 ton unit' can also be referred to as a 24000 btu unit and vice versa.
So... from the above - you can easily see that "2 tons" of Air conditioning is what is required to cool the 'average' home of 1100 sq ft. "roughly speaking."
Note: it is always best to have a professional 'size' your cooling/heating needs.
One of your questions was could you 'mix tonnage?'
The answer is 'usually you don't mix the tonnage of your outside/inside units.' However, professionals sometimes do (mix the tonnage) in certain situations, and installing a 2.5 ton outside unit with an existing 2 ton inside unit is often done, however, there are some 'tech issues' here and - I would "again" recommend that you call a Service Tech to help you with the sizing/mixing of your cooling/heating needs.
hope this has helped
