Absolutely NOT ! you will end up with more problems,and spend more redoing it because it doesn't work together.And besides a 4 ton compressor needs a 4 ton condensor.3 ton condensor will not have the surface area to cool the freon from a hot vapor to a cool liquid,that is needed for optimal performance in air handler,which is also rated for a 4 ton ,due to the coil size and the expansion valve size.
for a given air conditioner: the faster the condenser (outdoor) fan the lower the suction pressure. the faster the evaporator (indoor) fan the higher the suction pressure.
There are 2 coils. 1 inside the indoor air handler or furnace and 1 outside on your condenser in the yard.
Yes a compressor will run the entire heating and cooling cycle, unless its in emergency heat in which case you will not have compressor operation. Defrost cycle is the AC mode except the outdoor fan is de energized to assist in the defrosting of the outdoor coil.
It is important to keep the air conditioner clean and know how to remove mold as it can reduce the efficiency of the air conditioner and also cause a foul smell . You should clean the condenser and the indoor unit.
That tells me the problem is with the outdoor unit. Most likely a dead compressor or fan motor. Additionally, your indoor and outdoor units are not on the same breaker.
Dirty condenser coils, high outdoor temp and heavy indoor load if coils are clean. Overcharge.

If the term "condenser" is reffering to the "condensing unit", the answer is yes. The combination of indoor coils and outdoor units is how the overall SEER is derived. The ARI website lists many combinations of these units.
More information is needed to solve this problem. First, which coils ar freezing? (indoor or outdoor) Next, are coils clean and free from obstuction? Recommend clean all coils, visual inspection of compressor unit, and check freon charge level. Under charge can cause icing of indoor coils.

OK, Check what you can (breaker, fuses, does the indoor unit run? does the compressor relay which is powered from the indoor unit pull in?) and repost with more specific info then maybe someone can help. Help us out little.
