How we handle AHU cleaning in Langley Heath
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with dust-coated heating and cooling coils and condensate trays that won’t empty, on internal panels, dampers and louvres and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
The paperwork matters as much as the work. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Between visits
To keep the system working properly between visits:
- Check the drain tray is emptying during routine visits
- Don’t ignore odours coming through the grilles
- Change filters on schedule and log each change
- Diary the inspection date recommended in the report
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, rather than waiting for a problem.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
Langley Heath buildings and their air
Going by the FSA’s register, there are about 5 schools, colleges and universities and about 3 hospitals, care homes and childcare premises serving food in Langley Heath and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. For Langley Heath, the closest hospital is KIMS hospital, roughly 3.9 miles north-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. At about 35 miles from central London, Langley Heath sits well inside the area we cover. Evening, overnight and weekend visits are all possible.
If you manage a school such as Senacre Technology College, ventilation cleaning is best booked for the holidays.

When to call us in Langley Heath
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
If you notice any of these, it’s worth a diagnosis:
- Dust-coated heating and cooling coils
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Dirty fans and fan housings
KIMS hospital, about 3.9 miles north-west, is the nearest hospital to Langley Heath, and healthcare sites of every size need their supply air kept clean.

Do you cover smaller places like Langley Heath?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.

Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Our emergency line runs 24/7, but a planned visit to Langley Heath is calmer for everyone.
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 we start.
