About our AHU cleaning in Lower Beeding
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. Common call-outs are for blocked condensate drains and slimy trays and fan sections that haven’t been cleaned in years, on drain trays, supply and extract fans and filter sections.
Work in a small place like Lower Beeding 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’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Different parts, different methods
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Lower Beeding before we set off.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- The unit is shut down with your site team and the area 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.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet

What else we do in Lower Beeding
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
When something else is needed
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- The supply and extract ducts, quoted separately
- Mechanical faults with motors, belts or bearings
- Problems with the unit’s controls or sensors
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly before you book.
Parts of the system we cover
- Internal panels
- Supply and extract fans
- Dampers and louvres
- Heating and cooling coils
- Drain trays

Do you need AHU cleaning in Lower Beeding?
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Clients usually contact us after spotting one of these:
- Drain trays holding standing water
- Units needing a clean before a new tenant or handover
- Leaves and litter drawn into the unit
- Dirty filters cutting the airflow
Wherever a school like Holy Trinity CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Lower Beeding: your questions answered
Is Lower Beeding in your area for AHU cleaning?
Yes, Lower Beeding is within the area we cover across London and the South East. A fixed quote usually follows within one working day of the survey details.
Can the work in Lower Beeding be done at night or at weekends?
Yes, nights and weekends are routine for us. The work in Lower Beeding can fit around your hours. Tell us your opening hours when you ask for a quote.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Can you fix a faulty AHU?
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 come out in an emergency?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711 or use the quote form.
When should our AHU next be cleaned?
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.
Between visits
So the system stays in good health:
- Don’t store bins or materials near the intake
- Keep inspection doors on the unit in good order
- Report musty smells from the vents straight away
- Keep the certificate and photo report with the plant records
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
