Written from Air It Up's first-hand field experience across Greater New Orleans since 2000 and reviewed for accuracy by owner Mike Mavromatis. Equipment specifics (warranty terms, efficiency ratings) reflect manufacturer-published information at the time of writing — always confirm current terms for your exact model.
The decision factors
Weigh age, safety, repair cost, and efficiency (AFUE for furnaces, HSPF for heat pumps). A safety defect overrides everything else.
When safety forces replacement
A cracked gas furnace heat exchanger can leak carbon monoxide and is not safely patched — that is a replace, not a repair. Any combustion-safety failure ends the debate.
Failure modes
Ignoring a safety issue to save money is dangerous; on the other end, replacing a whole system for a simple igniter or sensor is wasteful. Diagnose first, then decide.
Proof and your next step
We will never invent a safety scare to sell a furnace, and we will not let a real one slide. Use the repair-or-replace guide.
Frequently Asked Questions
- Is a cracked heat exchanger repairable?
- No. A cracked heat exchanger is a carbon-monoxide risk and is not safely repaired — the furnace should be replaced. This is one case where replacement is non-negotiable.
- When is a furnace too old to repair?
- Once a furnace is old, inefficient, and needing repeated or major repairs, replacement usually wins. We weigh age, safety, and cost and give you an honest recommendation.
