AHU cleaning around Moorhouse Bank

Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 1 mile south-west of Moorhouse Bank is Tandridge Priory, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. London plant rooms are often on roofs or in basements reached through occupied floors.

About our AHU cleaning in Moorhouse Bank
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. The work covers internal panels, dampers and louvres and drain trays, and the jobs we see most are blocked condensate drains and slimy trays and dust-coated heating and cooling coils.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so ventilation cleaning in Moorhouse Bank is usually planned out of hours. Parking and loading are agreed with the building in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What affects the quote in Moorhouse Bank
Sites vary more than people expect. What affects the quote:
- The times the site is available
- Site requirements such as sign-in and permits
- One-off work versus a regular cycle
- The condition we find in the survey
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.
Helping us quote
To speed up the quote, send us:
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The site address and the type of premises
For a fixed quote, phone us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
What we are called out for in Moorhouse Bank
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Any of these means the system needs a check-up:
- Air handling units due a clean after building work
- Rooms that smell stuffy when the system runs
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
School buildings such as Oxted School are usually done in the holidays, so classrooms are not disturbed.
Questions to ask before you book
- What paperwork you get at the end
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the quote is based on a survey or photos
- When the next visit should be, and why
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Clear leaves and litter away from the intake
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
- Keep filter changes on time and recorded
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
FAQs for Moorhouse Bank
How do you handle parking and loading in Moorhouse Bank?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Do you work overnight in Moorhouse Bank?
Yes, nights and weekends are routine for us. It means the site in Moorhouse Bank keeps running as normal. Just phone us on 0345 646 2711 or send us an email with your opening times and we will plan around them.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
How long will the unit be out of action?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, including evenings or weekends.
What happens to the waste?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

How the job changes from site to site
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
How it works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Moorhouse Bank.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
