About our AHU cleaning in Ruislip Manor
We clean air handling units for buildings in Ruislip Manor and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers heating and cooling coils, dampers and louvres and internal panels, and people most often call us about blocked condensate drains and slimy trays and dirty filters cutting the airflow.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. In Ruislip Manor, as elsewhere, cleaning starts with an inspection of what’s there.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

How the job changes from site to site
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Ventilation in Ruislip Manor buildings
Food Standards Agency data includes about 29 schools, colleges and universities and about 29 caring premises (care homes, nurseries and hospitals) in Ruislip Manor and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 2.2 miles north of Ruislip Manor is Northwood and Pinner Cottage Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours.
Wherever a school like Lady Bankes Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. It also means the next inspection has less to find. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Managing agents and facilities teams in Ruislip Manor
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.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site to keep disruption down.
Ruislip Manor questions
Can ventilation in schools around Ruislip Manor be cleaned out of term?
Yes. The holidays are the usual time for school work. Around Ruislip Manor, the Food Standards Agency lists about 29 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Can you come to Ruislip Manor after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What happens if you cannot reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Between visits
Think of this as the after-treatment advice, short and simple:
- Do not ignore odours coming through the grilles
- Book the next check in line with the report
- Change filters on schedule and log each change
- Clear leaves and litter away from the intake
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.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What happens on the day
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes half a day to a full day per unit, with large plant planned over several shifts, and the area is cleaned down before we leave. Getting kit into a London building takes planning, so let us know where we can load and park in Ruislip Manor.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
How to prepare
- Dig out any earlier paperwork for the system
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
Get a fixed quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Do you need AHU cleaning in Ruislip Manor?
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Common reasons sites call us include:
- Plant that has been serviced but not cleaned
- Condensate trays that won’t empty
- Dirty coils holding back the airflow
- Fan sections that haven’t been cleaned in years
Healthcare ventilation, from large hospitals like Northwood and Pinner Cottage Hospital (about 2.2 miles north) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before you book
- Whether inaccessible sections are listed on the report
- Whether a survey comes first
- Which accreditations they hold, and whether you can check them
- Exactly which parts of the system are covered
