Overwhelmingly, yes. Matching a new condensing unit with a new coil is the only reliable way to be certain you are going to get the rated efficiency of the new equipment. Matching a new, high SEER (seasonal energy efficiency ratio) condensing unit with an old indoor coil probably would not result in optimum efficiency.

This depends largely on individual circumstances: for example, how large is the area to be cooled, how large is the family, what temperatures are required, how well is the house insulated, where is the house located etc. Central and attic-based systems require internal ducting. Ductless air conditioning requires wall space. In most circumstances, if more than three rooms need cooling, it is best to consider a central or attic-based system.

Manufacturers publish equipment efficiency ratings that are available to your contractor. ARI (Air Conditioning and Refrigeration Institute) also publishes directories indicating various energy efficiency ratings of specific equipment. It is important that a contractor install a unit that has just the right capacity to cool your home. Units with excess capacity will cycle on and off and work less efficiently, thus increasing your operating costs.

Because newer equipment usually is more energy efficient than older cooling systems, you might actually save money by replacing your old system before it completely wears out. Contact your contractor and ask for an estimate. In some cases, the money you save in reduced utility costs might pay back your purchase price of a new system years earlier than you might think.

It can be surprisingly small on an annual basis, but it depends on how much you use your air conditioning, how efficient your equipment is, and how much you conserve energy by actions ranging from insulating your home to keeping doors and windows closed when the system is operating. Your local electrical company is the best source for specifics in your area.
