Repair vs Replace an HVAC System
Compare HVAC repair and replacement using system age, repair cost, efficiency, refrigerant, comfort and reliability.
Estimate hvac costWhen repair may be reasonable
A well-maintained system with a limited, affordable failure may be worth repairing when performance and comfort remain acceptable.
Reasons to consider replacement
Replacement becomes more attractive when several problems occur together.
- Repeated breakdowns
- Major compressor or heat-exchanger failure
- Poor comfort or humidity control
- Obsolete or costly refrigerant
- High operating cost and low efficiency
Request both options
Ask the contractor for the repair scope, expected remaining life, replacement alternatives and any required duct or electrical work.
