Access panels and fan hinges
You cannot clean what you cannot reach. Missing access panels and seized fan hinges can limit the cleaning scope. We document the limitation and quote access work separately.
Duct access doors
Access doors go where the duct layout needs them, not where they are easiest to cut. Once they are in, run that nobody could reach becomes part of the documented scope.
Fan hinge kits
A hinge lets the fan tilt back safely so the blades and housing can be cleaned. We check whether the hinge and fan access allow the quoted work and document any limitation.
Sequencing
Access work gets quoted before the clean, not sprung on you at 2 a.m. as a surprise line item. If we find the need during service, we stop, photograph it, and wait for your approval.
Questions for an access review
Included
- Does the report identify accessible duct sections and show photos at the access points?
- Does the report show the fan blades and housing?
- Is the duct length and layout recorded?
- Can each horizontal run and direction change be reached?
- Has an inspector identified an inaccessible section?
What an access door install involves
The opening gets cut and framed where the duct layout needs it: at direction changes, at the base of a vertical rise, and at intervals along a horizontal run. The door is gasketed and fastened so it seals closed and opens again next year without being destroyed.
We photograph the run before the door goes in and again when it is opened. The record shows the installed access and the section it reaches.
Questions we get
My duct was cleaned last year. Do I still need access panels?
Review the prior scope and photographs first. Missing photos leave a documentation gap; they do not prove that the run was not entered. We check the layout and available access before quoting any panels.
Will cutting an access door damage my duct?
A correctly framed and gasketed door is a repairable feature of the duct. What damages a duct is forcing a panel that was never built to open, year after year.
Can you install a hinge on any rooftop fan?
Most upblast fans take a standard hinge kit. Some do not, and some sit on a curb that needs attention first. We photograph the fan and the curb and tell you which one you have before quoting.
Do I have to buy the access work to get the cleaning?
No. They are quoted separately and you can decline the access work. The report then names what stayed unreachable. What we will not do is clean the reachable few feet and write down that the duct is done.
Who decides where the access doors go?
The duct layout does. We walk the run, mark the direction changes and the vertical rise, and show you the positions on the quote before anything is cut.

Tell us the hood and fan count and roughly when it was last cleaned. Photos of the hood, the filters and the rooftop fan speed the quote up considerably.
