Repair or replace HVAC: compare the same period and scope

Build an explicit cost comparison using your repair and replacement quotes, with unknown reliability kept visible.

Frequent repairs, rising bills and uneven comfort are reasons to seek a professional assessment. Equipment age is useful context, not a rule that automatically makes replacement the right answer. This planner uses a recorded installation date and never decodes age from a serial number.

Compare repair and replacement over the same number of years. Include initial work, annual energy and maintenance, and any explicitly assumed later repairs. Make sure each quote covers the work needed to restore comparable service. Do not count included membership visits twice.

The calculator below shows totals from the figures you enter. It cannot predict breakdowns, remaining life or comfort. Keep uncertain incentives outside the base total, record quote sources and ask the contractor what is excluded. A lower calculated cost is one consideration alongside technical condition and your plans for the home.
