not very well. a 4 ton system needs about 1600 cfm to provide it's full capacity of cooling. a 3 ton furnace puts out about 1200 cfm. in addition, the evap coil typically attached to the furnace needs to match the tonnage of the outdoor unit. so, the evap coil must be 4 tons. If you currently have a 3 ton furnace and evap coil, the system will not work, and you will most likely ruin the compressor in the outdoor unit.
Half way between the the condenser and air handler, in the liquid line.
you can probably get away with that just make sure you have an expansion valve on the evaporator. An expansion valve will keep liquid from getting back to the compressor.
It all depends on the efficiency of the unit you want (80%, 92%, 95% etc.), how big the unit is, and what brand you're going with. I recently replaced my gas furnace. We have a 3 ton unit for our house. We went with the 95% eff. unit because we were able to get a tax credit, it cost us a hair below $2500. The 80% unit was $1,400. The 92% unit was $1,800.="h2headingh2"style="color:rgb(0,0,0);"name="it_all_depends_on_the_efficiency_of_the_unit_you_want_(80%,_92%,_95%_etc.),_how_big_the_unit_is,_and_what_brand_you're_going_with._i_recently_replaced_my_gas_furnace._we_have_a_3_ton_unit_for_our_house._we_went_with_the_95%_eff._unit_because_we_were_able_to_get_a_tax_credit,it_cost_us_a_hair_below$2500._the_80%unit_was$1,400._the_92%unit_was$1,800.">
A Ton is the measurement of the amount of heat required to melt one ton of ice. It is also 12,000 BTU (British Thermal Unit) So the Ton is a measurement of the amount of heat that the refrigeration system can remove.
Work is defined as Force applied over a distance i.e. W=F*x. The units are, therefore, 1Newton*1meter=1Joule. Work is measured in Joules! Work is energy. Any unit used for energy is a perfectly good unit for describing work. The SI unit is the joule. Other examples include foot-pound, watt-second, kilowatt-hour, dyne-centimeter, ton-furlong, horsepower-hour, etc.
No. It will be less efficient.
You may be able to turn up the blower speed but you will probably still not get the appropriate cfm. You may be able to swap out the blower but you may run into problems with fitting the new one in place or the proper sizing of the return and supply duct work.

How much a 4 ton ac ruud condenser weigh
Installing a 3 1/2 ton condenser on a 3 tr evaporator will not function properly. There isn't enough evaporator coil surface area to absorb heat and vaporize refrigerant liquid for its return back to the condenser compressor. What can be done is a 3 ton condenser unit with a 3 1/2 evaporator coil.
The rating is technically a minimum. You could use a larger coil and have it work. But if its a Evaporator coil it will need to be matched on the far end with a similar or larger condenser coil. If the Condenser coil is larger it will probably just take a little more refrigerant.
It may run. But not efficiently or to capacity as there will probably not be enough air flow.You also run the risk of ruining the compressor by flooding it, as residential a/c units are notorious for not having hi and low pressure cut-out switches.
No easy answer with the information given. You might be able to increase the blower speed but that probable wont get you enough air anyways. You might be able change the blower depending on your furnace. Depending on the evaporator coil 3 or 5 ton you either wont remove the proper amount of moisture from the air(the biggest part of what makes you feel cool) or there will not be enough air blowing over the coil and it will freeze up. Technically could put a freeze switch to turn of the condenser. Most likely you will wear out the condenser quicker then it should.
A condenser is typically installed based on 400 square feet per (1) ton. That is, in a dwelling of 1800 square feet, a 4 & 1/2 ton unit, (for air conditioning), will be needed. Any less and the condenser will have to work too hard. Much more and the condenser will over work, (due to start-up and cool down energy overlapping, as well as the excess energy required to run the larger unit), thereby wasting money.
