What a duct cleaning change order is for
Surprises in duct cleaning come out of the ducts: a nest, a crushed flex run, a second air handler in the attic. Showing the owner a photo and getting a signature on the extra work before you do it keeps trust in a trade where trust is everything.
What to put on a duct cleaning change order
- What was found, with a photo.
- Added work and its price.
- Credits for skipped items.
- The new total.
- Owner's OK before the work.
A worked example
The tech finds a second air handler in the attic and a crushed dryer duct behind the machine. The owner skips the filter.
| Line | Qty | Unit | Price |
|---|---|---|---|
| Second system, attic air handler | 1 | each | Your price |
| Replace crushed dryer duct with metal | 1 | each | Your price |
| Credit: furnace filter | -1 | each | Your price |
Show the photo before you price the extra. In this trade, the owner needs to see it.
