Second opinion on major repair
A large price gap can reflect different components, labour, access, warranties or a mistaken diagnosis.
What to observe
Request model numbers, part numbers, measurements, photographs and separate labour/material charges.
A field example
If one contractor recommends a heat-exchanger replacement and another offers a cleaning, ask both for written evidence of the alleged defect. Treat a confirmed safety shutdown seriously while seeking clarification.
What the written work should say
Have another registered contractor assess the same documented problem and compare scope, not just the total.
Where this task stops
Do not delay action on a confirmed unsafe condition while shopping for routine service.
