Cleaning quote line items
The word 'furnace cleaning' can refer to cabinet, blower, burners, coil, ducts or a bundle.
What to observe
Compare line items for exact components, access method, protective measures, credentials and post-work verification.
A field example
One quote may include cabinet and filter while another removes the blower and cleans the coil. Put those components in adjacent columns before concluding that one contractor is dramatically cheaper.
What the written work should say
Request exclusions and add-on rates in writing before approval; compare like-for-like scope.
Where this task stops
A low advertised entry price and a complete-system quote cannot be compared without the included work.
