About our AHU cleaning in Broxted
Our AHU cleans for sites in Broxted cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers internal panels, heating and cooling coils and supply and extract fans, and the jobs we see most are coils clogged with dust and debris and dirty fans and fan housings.
Somewhere as small as Broxted, 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.
Good records are part of the job. 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.

What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. We agree a date with you, plan the drive to Broxted and turn up when the site is quiet.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Find the previous report, if there is one

Your questions about AHU cleaning in Broxted
Do you offer AHU cleaning in Broxted?
Yes. Our area runs across London and the South East, Broxted included. A fixed quote usually follows within one working day of the survey details.
Is Broxted within the area you cover?
Yes, Broxted is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What information do you need?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
Is there a survey before the work?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.
What’s included in an AHU clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What the work involves, part by part
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Fixed quotes for AHU cleaning in Broxted
Before we fix a price, we need to know a few things. We check:
- The scale of the work
- Site rules, permits and inductions
- The times the site is available
- One-off work versus a regular cycle
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or drop us a line, and we will talk you through it.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Broxted buildings and their air
At about 34 miles from central London, Broxted sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
Around Broxted, as anywhere, ventilation cleaning begins with an inspection. Whether the building is in Broxted itself or nearby, filters, coils, drain trays and ducts are all part of the work.
Broxted is about 7 miles north-east of Bishop's Stortford, in Essex. We provide AHU cleaning for businesses, landlords and public buildings in Broxted and the rest of Essex. Our area takes in 644 places across Essex, large and small. There’s also a page for Chelmsford, about 15 miles away.
We work across CM6 for AHU cleaning and the streets around it. That includes premises on St Mary's Mews and Cranham Road and nearby roads. If your site is just outside Broxted, we cover Brick End (1 mile south), Henham (2 miles west), Debden Green (3 miles north), Fuller's End (3 miles west) and Elsenham (3 miles west). Larger places within reach include Chelmsford (15 miles south-east), Braintree (12 miles east), Harlow (13 miles south-west), Saffron Walden (7 miles north), Halstead (15 miles east) and Great Dunmow (4 miles south-east).

What your team can do, and what needs us
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Aftercare tips
To keep the system working properly between visits:
- Stick to the filter change plan
- Book the next check in line with the report
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
