For cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Chase Cross, one call is all it takes, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Stale or musty smells from the ventilation
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A quieter site near Chase Cross still needs its system looked after.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

How we handle AHU cleaning in Chase Cross
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you are dealing with plant that needs cleaning after a refit and dirty fans and fan housings, we can help.
Visits to a place like Chase Cross are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
How the job changes from site to site
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.

Do you need AHU cleaning in Chase Cross?
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Clients normally contact us when they notice something like this:
- Condensate trays that won’t empty
- Units needing a clean before a new tenant or handover
- Stale or musty smells from the ventilation
- Filters that are clogged or overdue

Chase Cross: your questions answered
Do you work at weekends in Chase Cross?
Yes, evening, overnight and weekend work is normal for us. The work in Chase Cross can fit around your hours. Let us know the hours you’re closed and we will book within them.
Can you clean school ventilation in Chase Cross during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Chase Cross, the Food Standards Agency lists about 15 schools and colleges with registered kitchens within a mile and a half or so. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Can you clean the ducts connected to the AHU?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
What does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before any work starts.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Tell us about any gates, ladders or locked plant areas at your site near Chase Cross when you book.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading

Advice
What AHU cleaning can’t fix
We’d rather tell you now than book work that will not help, so here are the limits:
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before booking.
What we work on in Chase Cross
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
Staff cleaning versus specialist work
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
