Short answer

The right answer depends on property condition, complete scope, local requirements and the consequences of waiting. Document the symptoms, compare like-for-like scopes and ask a qualified professional to explain the assumptions.

Safety first: Leave combustion, refrigerant and electrical work to properly qualified professionals.

What changes the answer?

Age and condition matter, but so do access, materials, prior work, code requirements, hidden damage and local labor. A reliable recommendation states what was observed, what remains unknown and what would cause the plan to change.

Questions to ask before deciding

  • What evidence supports this recommendation?
  • Which parts of the scope are required, optional or allowances?
  • What could be discovered after work begins?
  • Which permits, credentials and inspections apply locally?
  • What warranty covers labor, materials and follow-up?

A practical next step

Take clear photographs, gather service records and write down when the problem began. Compare the reasoning behind recommendations—not only the total price—and ask for a complete written scope.
