AHU cleaning in Aldham, done properly
If the units serving a building in Aldham have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for plant that has been serviced but not cleaned and dust-coated heating and cooling coils, on internal panels, dampers and louvres and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Coils that are corroded or leaking and need replacing
- Problems with the unit’s controls or sensors
- Mechanical faults with motors, belts or bearings
If you’re not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer.
What the work covers
- Supply and extract fans
- Heating and cooling coils
- Filter sections
- Drain trays
- Dampers and louvres
- Internal panels
Why act early in Aldham
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. It’s simpler to plan the work at Aldham now than to arrange it in a hurry later.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

The process
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Aldham.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down

Advice
Signs you need AHU cleaning in Aldham
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Signs it’s time to call us include:
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
- Dirty coils holding back the airflow
- Stale or musty smells from the ventilation
If you manage a school such as Holy Trinity CofE Primary School, ventilation cleaning is best booked for the holidays.
What your quote should include
- Whether a survey comes first
- Whether VAT is included

Aldham questions
Can you work in Aldham outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Aldham needn’t be disturbed. Your opening times are the first thing we ask for.
Do you offer AHU cleaning in Aldham?
Yes. We work across London and the South East, and Aldham is part of that. Get in touch with the details and we’ll arrange a survey.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few photos and any previous report.
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 for anything urgent, ring our 24/7 emergency line.
Can one contract cover all our sites?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.
Staff cleaning versus specialist work
In-house cleaning and specialist cleaning do different jobs. 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. That part needs specialist access and equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

What else we do in Aldham
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Keep the certificate and photo report with the plant records
- Report stiff or damaged access doors
- Clear leaves and litter away from the intake
- Flag stale or damp smells in the supply air
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What affects the quote in Aldham
We quote each job individually. These are the things that affect it:
- Where the site is and how we reach it
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- Photos showing the whole system and its surroundings
- The site address and the type of premises
- Your last certificate, test record or report
- Any access panels or hatches you can see
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
