Start with four numbers
- Age of the system
- Cost of the proposed repair
- Recent repair history
- Typical seasonal operating cost
A single expensive repair does not automatically mean replacement is smarter. The question is whether the repair buys meaningful additional life at a reasonable cost.
Useful rule: ask the contractor to price both the repair and a comparable replacement so you can compare real numbers instead of making the decision under pressure.
Get a second opinion when
The diagnosis involves a compressor, refrigerant leak, major control board, heat exchanger, or a recommendation to replace a system that is still relatively young.
Questions to ask
- What failed, specifically?
- Can you show me the failed reading, leak location or damaged part?
- What warranty applies to this repair?
- If I repair it, what other major components are near end of life?
- What efficiency improvement would replacement realistically provide?
