As a long time ago energy conservation guru, we found an older A/C unit when replaced with a higher seer rated system saves enough money to generally pay for itself. That being said think most of the HVAC geeks will tell you to replace whole system,, So you win twice. Consumer Reports has some nifty info on frequency of repair if you decide to purchase replacement. You can peruse at local library if not a subsciber. Depending on your primary heating system and where you are located may be to your advantage to replace furnace as well,, Many of the local utilites have financing plans.

Angie's List is good source for HVAC contractors rated by your peers.

While replacing the condensing unit only at this time may not cause any future problems, there will almost certainly be added expenses when the air handling portion(furnace) does need to be replaced.
When replacing the outdoor unit it is advisable to replace the evaporator coil also(matched equipment is always better). The evap coil is attached to the furnace(indoors) and there is a considerable amount of work(cost) involved to replace. When the furnace is replaced(sometime later) then all that work(cost) has to be repeated.
Remember, ALWAYS hire a LICENSED contractor when performing work on your home!

You do not have to replace both units, however it is best toreplace both at the same time. Bothunits and coil work together so your units are only as good as the weakest linkand matched systems are preferred. Most LicensedContractors have financing plans and some utilities have rebates on qualifyingsystems.

Not that the government is always right, but in Florida the building would require you to replace the outdoor unit and the indoor coil as a minimum, so you have a proberly matched system and meet the required minimum SEER(efficiency). As others have stated it is best to do this, and little reason not to,other then cost. However without a matched system and known SEER, it might cost you enough more to operate then the cost to replace the indoor coil savings, over just a few years. I would definately replace both.
