    Coil or whole system

    A leaking evaporator coil is a common reason an older AC stops cooling. This Old House notes that if the coil is still under warranty, you pay mainly for labor and materials, so check your paperwork before you approve the job.

    On an older system, get a quote for a full replacement too. A new coil on an old system can leave you paying again when the compressor fails. See our central air installation cost and AC compressor replacement cost pages.

    Ask whether the new coil matches your outdoor unit, because a mismatch hurts efficiency.
