Can I Just Replace the Outdoor Unit on an Older Air Conditioning System to Save Money?
It may cost less initially to replace the outdoor unit on an older system. However, over time utility expenses will add up and may even cost you more. Replacing only the outdoor unit will lower the efficiency of the unit and the system may fail sooner than normal; most manufacturers’ warranties will be voided after one year. Matching your units now may have an extended warranty if registered online.
