AHU cleaning in Rivenhall
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, internal panels and filter sections, and people most often call us about dirty filters cutting the airflow and units that have only ever had filter changes.
Somewhere as small as Rivenhall, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Make sure the unit’s access doors open easily
- Keep the area around the fresh air intake clear
- Look at the condensate drain whenever the unit is serviced
- Keep the certificate and photo report with the plant records
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
In-house cleaning or a specialist?
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.

What we’re called out for in Rivenhall
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Clients normally contact us when they notice one of these:
- Plant that has been serviced but not cleaned
- Air handling units with blocked filters
- Air handling units due a clean after building work
- Blocked condensate drains and slimy trays
Healthcare buildings such as William Julien Courtauld Hospital, about 5.6 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Rivenhall, yours matters too.
Before booking anyone

How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- Travel, parking and unloading
- The scale of the work
- Whether several sites go on one quote
- Any permits to work or inductions
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
- A few general shots of the system

Questions from Rivenhall
Can the work in Rivenhall be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Do you cover smaller places like Rivenhall?
Yes, Rivenhall is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Rivenhall before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
