Here are the options to replace the Condenser and Coil. Good option is Standard change-out similar to what you have. Better option is a upgrade efficiency condenser. Going from a 14 seer to a 16 seer. Best option is the 2 stage condenser. Starts at 16 seer full capacity but will increase in efficiency when only in half capacity.
