Wokingham · Air handling unit cleaning
Langley Common AHU cleaning
AHU cleaning for businesses, landlords and public buildings in Langley Common. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Dirty coils holding back the airflow
- Air handling units due a clean after building work
- Dust built up on fan impellers
Common problems we fix in Langley Common
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
Common reasons sites call us are:
- Dust-coated heating and cooling coils
- Condensate trays that will not empty
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
Hospitals such as Wokingham Hospital (about 2.4 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Langley Common are no different.
Questions to ask before booking
- What paperwork you get at the end
- Whether they recommend a next date
- Whether the price is fixed
- Whether the quote is based on a survey or pictures
AHU cleaning in Langley Common
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers supply and extract fans, dampers and louvres and heating and cooling coils, and people most often call us about filters that are clogged or overdue and air handling units never cleaned inside.
Work in a small place like Langley Common starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Report water on the plant room floor
- Diary the inspection date recommended in the report
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
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.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Coils that are corroded or leaking and need replacing
- A system that is undersized for the building
- Controls and BMS settings that run the unit
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think.

Ventilation in Langley Common buildings
Food Standards Agency records list about 3 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) registered as food businesses in Langley Common 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. Wokingham Hospital is the nearest hospital, about 2.4 miles north-east of Langley Common. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Langley Common is about 35 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
If you manage a school such as The Coombes Church of England Primary School, ventilation cleaning is best booked for the holidays.

Why it’s worth doing now in Langley Common
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a planned clean is far less disruptive than a breakdown. It’s worth booking a check, because nobody sees inside a duct day to day.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

Langley Common: your questions answered
Is Langley Common within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Langley Common included. Let us know about access, parking and anything unusual about getting there when you book.
Can a school’s ventilation in Langley Common be done out of term time?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Langley Common. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Do you need to switch the unit off?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and we usually come back within one working day. If pictures are not enough, we will survey first.
Different parts, different methods
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. The timing of a visit to Langley Common is set by you, and the travel is our side of the planning.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Have your last certificate or report to hand
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
