Can you use a 13 seer condensor with a 10 seer coil?

it will work but you will not reach the rated seer rating. also you will have oil return problems due to less refrigerant volume (because the newer 13 seer units run a lower head pressure. this problem can be resolved by installing a thermostatic expansion valve (txv) but when it is all said and done just go to 410-a with both units because r-22 is not going to be reproduced after 2010.
