Extraction cleaning - self-inspection
Professional cleaning happens on a cycle, but grease builds up continuously in between. A few simple checks of your own, between the professional cleans, help you spot a problem developing early - a system loading with grease faster than expected, or a sign that cleaning is due sooner than planned. Here is how to keep an eye on your own ductwork.
The short answer
Between professional cleans, you can keep an eye on your own ductwork with a few simple checks of the accessible parts. Look at the grease filters and canopy, where grease build-up shows first and fastest. Look at any accessible access points into the ductwork, if you can see inside, for signs of grease accumulating. Watch the extraction's performance - whether it is still drawing the air away effectively, since a drop can indicate grease building up. And watch for the general signs of grease build-up - dripping, smell, visible grease. These checks do not replace professional cleaning, but they help you spot a problem developing between cleans, so you can act - bringing the clean forward if the grease is building faster than expected.
Grease builds up between cleans
Professional ductwork cleaning happens periodically, on a cycle set by how fast the system accumulates grease - but grease builds up continuously in the meantime, between one clean and the next. Usually the cycle is set so that the grease is removed before it builds up too far, but circumstances can change: a busier period, more cooking, or a system loading faster than expected can mean grease building up more quickly than the cycle assumes. So there is value in keeping an eye on your own ductwork between the professional cleans - to notice if the grease is building faster than planned, so you can act rather than wait for the next scheduled clean.
A few simple checks of your own are what let you do this. They do not replace the professional cleaning - which reaches inside the system and removes the grease thoroughly, as your own checks cannot - but they let you monitor the accessible signs of grease build-up between cleans, so a developing problem is spotted early. If your checks show the grease building up faster than the cycle allows for, you can bring the professional clean forward, keeping the grease and fire risk under control rather than letting it build unchecked until the scheduled clean. So self-inspection between cleans is a useful complement to the professional cleaning cycle, helping catch a system that is loading faster than expected.
Check the filters and canopy
The most accessible and useful things to check are the grease filters and the canopy, because this is where grease build-up shows first and fastest. The filters catch grease from the air, so they load with grease quickly and visibly - checking them shows how fast grease is accumulating. If the filters are heavily greased soon after cleaning, that indicates the system is loading with grease quickly, which is a useful early sign. The canopy, too, shows grease accumulating - on and around it, grease build-up is visible and tells you how the system is loading.
These are things you can readily look at yourself, without special access or equipment, so they are the natural focus of a self-check. Looking at the filters and canopy regularly - noticing how greasy they are getting and how quickly - gives you a feel for how fast your system is accumulating grease, which is the key thing self-inspection can tell you. If they are loading faster than usual, the whole system is likely accumulating grease faster, which is a prompt to consider whether the professional clean is needed sooner. So the filters and canopy are the first and easiest things to check, giving a readable indication of the system's grease loading between professional cleans.
Look at access points and airflow
Beyond the filters and canopy, there are a couple of other things worth checking if you can. If your ductwork has accessible access points that let you see inside, looking in through them - where it is safe and practical to do so - can show grease accumulating inside the ductwork itself, which is where the important build-up is. This is not always possible or easy for a duty holder to do safely, but where there is accessible visibility into the ductwork, it can give a direct look at the grease build-up inside, which is the most relevant thing of all.
The other useful check is the extraction's performance - whether it is still drawing the air away effectively. A noticeable drop in the extraction's performance - the kitchen getting smokier or hotter, the extraction seeming weaker - can indicate grease building up in the system and restricting the airflow. So watching how well the extraction is working is an indirect check on the grease build-up: if the performance is dropping, grease accumulation may be the cause. This is a useful thing to be aware of, because it can signal a build-up affecting the system even before it is obviously visible. So alongside the filters and canopy, checking any accessible view inside the ductwork and watching the extraction's performance round out the useful self-checks.
Watch the signs, and act on them
Alongside these checks, it is worth watching for the general signs that grease is building up - dripping grease, a lingering smell, visible grease accumulating - which are the everyday indications that the system is loading. Noticing these between cleans is part of keeping an eye on the ductwork, and they reinforce what the filter and canopy checks show. Together, the checks and the signs give you a picture of how your system is accumulating grease between the professional cleans, so you are not relying solely on the scheduled cycle but actively monitoring the actual build-up.
The point of all this is to act on what the checks show. If your self-inspection indicates the grease is building up faster than expected - the filters loading quickly, grease accumulating visibly, the performance dropping, the signs appearing - then the sensible response is to consider bringing the professional clean forward, rather than waiting for the scheduled date while the grease builds beyond where it should. So the value of self-inspection is that it lets you adjust to the actual loading of your system, catching a faster-than-expected build-up early and acting on it. It does not replace the professional cleaning that reaches inside and removes the grease properly - but it complements it, giving you a way to monitor between cleans and respond if the grease is building faster than the cycle assumes. A few simple checks, watched and acted on, keep you on top of your ductwork between the professional cleans that do the thorough work.
The takeaway
Professional cleaning happens on a cycle, but grease builds up continuously in between - and circumstances can make it build faster than the cycle assumes. So a few simple checks of your own, between the professional cleans, help you spot a developing problem early. Check the grease filters and canopy, where build-up shows first and fastest; look inside any accessible access points, if you safely can, for grease accumulating in the ductwork; watch the extraction's performance for a drop that could indicate build-up; and watch for the general signs - dripping, smell, visible grease.
These checks do not replace professional cleaning, which reaches inside the system and removes the grease thoroughly as your own checks cannot - but they complement it, letting you monitor the accessible signs of grease build-up between cleans. If your checks show the grease building faster than expected, the sensible response is to consider bringing the professional clean forward, rather than waiting while the grease builds beyond where it should. So keep an eye on your own ductwork between the cleans: a few simple checks, watched and acted on, let you stay on top of the actual grease loading of your system, catching a faster-than-expected build-up early.

Yes - a few simple checks of the accessible parts help you spot grease building up early. They do not replace professional cleaning, which reaches inside the system and removes the grease thoroughly, but they let you monitor the signs of build-up between cleans and act if the grease is building faster than expected.
The grease filters and canopy, where grease build-up shows first and fastest. The filters load with grease quickly and visibly, so checking how greasy they are getting and how quickly gives a feel for how fast the system is accumulating grease. The canopy also shows grease accumulating on and around it.
If your ductwork has accessible access points that let you safely see inside, looking in can show grease accumulating in the ductwork itself - the most relevant build-up. But this is not always possible or safe for a duty holder to do, so it is a check to make only where there is accessible, safe visibility into the ductwork.
A noticeable drop in performance - the kitchen getting smokier or hotter, the extraction seeming weaker - can indicate grease building up and restricting the airflow. So watching how well the extraction works is an indirect check on the grease build-up, which can signal a problem even before it is obviously visible.
The general signs that grease is building up - dripping grease, a lingering smell, visible grease accumulating. Noticing these between cleans reinforces what the filter and canopy checks show, together giving a picture of how the system is loading with grease so you are not relying solely on the scheduled cycle.
Consider bringing the professional clean forward, rather than waiting for the scheduled date while the grease builds beyond where it should. The value of self-inspection is letting you adjust to your system's actual loading - catching a faster-than-expected build-up early and acting on it, complementing the professional cleaning cycle.
Your own checks between cleans help you spot grease building faster than expected - and our professional cleaning does the thorough work your checks flag, reaching inside the system to remove the grease.
