SOURCE: Carrier air handler tonnage?
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?

its a 3 ton unit manufactured in 2005
the 36 in the model number indicates tonnage 12,000 btu's to a ton times 3 equals 36
the 2005 in the serial indicates year made not sure what month but if i had to guess i'd say May of '05
