Estimated result

$906/year

$76 monthly set-aside across service, filters, and the repair reserve.

How to use this estimate

  • Keep the repair reserve in a liquid home-maintenance account.
  • Older equipment may justify a larger reserve and a separate replacement fund.
  • Maintenance contracts differ; compare exclusions, priority service, and parts discounts.

Transparent method

We expose the planning formula so you can challenge it and replace assumptions with local evidence.

systems × annual service + monthly filters × 12 + repair reserve

What this calculator cannot see

  • This is a budgeting tool, not a forecast of failures.
  • Rental properties and commercial-use equipment may need different schedules.

Professional verification

Use this result to prepare questions and compare scenarios. Final equipment selection, electrical work, refrigerant work, combustion, duct design, and permitting should be handled by qualified professionals following local codes and manufacturer instructions.
