AHU cleaning in Rush Green
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you are dealing with air handling units with blocked filters and condensate trays that won’t empty, we can put it right.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Rush Green.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We take into account:
- One-off work versus a regular cycle
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- Any permits to work or inductions
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What to send for a quote
There’s no need for technical detail. Just send:
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
- Your last certificate, test record or report
- Any access panels or hatches you can see
For a fixed quote, phone us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Your questions about AHU cleaning in Rush Green
Does London parking affect a job in Rush Green?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Can you work in Rush Green outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Rush Green does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We will flag anything we notice during the clean.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
When something else is needed
To be straight with you, there are a few things this work will not fix:
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
If you are not sure, just give us a ring on 0345 646 2711 or use the quote form and we’ll give you a straight answer.

Advice
What we’re called out for in Rush Green
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Look out for these warning signs:
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
Workplaces around Romford station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
What your quote should include
- What happens if part of the system cannot be accessed
- Whether the price is fixed
- When the next visit should be, and why
- Whether the quote shows VAT
Aftercare tips
Simple habits between visits make a real difference. Our advice:
- Book the next check in line with the report
- Do not ignore odours coming through the grilles
- Don’t store bins or materials near the intake
- Watch for drips or damp patches near the plant
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
