AHU cleaning in Lampton
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. We’re often asked to deal with dust-coated heating and cooling coils and condensate trays that won’t empty, across drain trays, internal panels and heating and cooling coils.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Lampton, as elsewhere, cleaning starts with an inspection of what’s there.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Lampton
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
The symptoms we’re asked about most include:
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Drain trays holding standing water
- Odours coming through the supply air
Healthcare ventilation, from large hospitals like Hounslow Hospital (about 0.8 miles south-west) to small clinics, depends on clean filters, coils and ducts.

What else we do in Lampton
How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- How easy every part is to reach
- The number of sites or systems
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or send us an email, and we’ll explain what it covers.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
- Wide pictures of the system and the area around it
To get a fixed quote, give us a ring on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
What happens on the day
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. In a London area like Lampton, parking, loading and building access are planned before the day of the work.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Agree a time when the area can be out of use
- Let us know about permits to work or site inductions
- Let us know about parking and loading
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Multi-site and managed buildings
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 are happy to quote for all of it.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Ventilation in Lampton buildings
Food Standards Agency data includes about 47 schools, colleges and universities, about 48 care, childcare and hospital premises and about 11 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Lampton. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 0.8 miles south-west of Lampton is Hounslow Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Ventilation cleaning in London buildings is typically planned for evenings or weekends.
School buildings such as Alexandra Primary School are typically done in the holidays, so classrooms aren’t disturbed. For workplaces around Hounslow station with mechanical ventilation, cleaning can be done in the evening or at weekends.
Lampton is about 2 miles north-west of Twickenham, in Greater London. We carry out AHU cleaning for commercial premises of every kind in Lampton and the rest of Greater London. Lampton is one of 764 places in Greater London where we work for commercial clients. We also work in London, about 12 miles from Lampton.

What’s near Lampton
Locally, jobs take us to businesses close to Moon Under Water pub, Inwood Park and Kingsley Academy. Lampton’s nearest station is Hounslow station, about 0.9 miles south. Other landmarks nearby include Museum of Army Music (1.4 miles south) and Hounslow Hospital (0.8 miles south-west). Green spaces nearby include Long Wood and Garden Lake.
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Stick to the filter change plan
- Keep the certificate and photo report with the plant records
- Make sure the unit’s access doors open easily
- 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 survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Lampton questions
Do you clean school ventilation in Lampton in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Lampton, the Food Standards Agency lists about 47 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
How do you handle parking and loading in Lampton?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, usually makes it simpler.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we’ll typically reply within one working day.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and pictures.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. If pictures are not enough, we will survey first.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
When something else is needed
AHU cleaning cannot fix everything, and we will tell you before we start. It doesn’t solve:
- Faulty motors, drives or bearings
- Problems with the unit’s controls or sensors
- Airflow problems caused by the system’s design
If you’re not sure, just call us on 0345 646 2711 or drop us a line and we’ll give you a straight answer.
