AHU cleaning in Aldworth, done properly
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. We are often asked to deal with rooms that smell stuffy when the system runs and dirty filters cutting the airflow, across drain trays, filter sections and supply and extract fans.
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.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

How the job changes from site to site
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
When it’s something else
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.

What affects the quote in Aldworth
Every site gets its own quote. These are the things that affect it:
- How big the system is
- Whether we need access equipment or extra panels
- Any permits to work or inductions
- What state the system is in
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
Helping us quote
Before you ask for a quote, gather:
- The times we could work without disrupting the site
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
To help us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Once you have those, give us a ring on 0345 646 2711 or use the quote form.
Your questions about AHU cleaning in Aldworth
Do you cover smaller places like Aldworth?
Yes. Aldworth is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Aldworth?
Yes. We work evenings, overnight and at weekends. That way a site in Aldworth does not have to lose a day’s trading. Your opening times are the first thing we ask for.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, usually ready within one working day.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
Is a quote from pictures possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What happens on the day
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes half a day to a full day per unit, with large plant planned over several shifts. Seeing the system in photos first means the trip to Aldworth can be planned properly.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Before we arrive
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive
- Mention any locked doors, roof access or ceiling voids

Related advice
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
What happens if it’s left?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Aldworth simpler. With notice, the visit to Aldworth can be fitted around your bookings and events.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
