Air handling unit cleaning in Ridley, Kent
Air handling unit cleaning in Ridley, surveyed first and signed off with a written report and photos. Ask us for a fixed quote.
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
- Plant that needs cleaning after a refit
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Don’t ignore odours coming through the grilles
- Report stiff or damaged access doors
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
AHU cleaning in Ridley
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers drain trays, filter sections and heating and cooling coils, and the jobs we see most are odours coming through the supply air and fan sections that haven’t been cleaned in years.
Work in a small place like Ridley starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

AHU cleaning around Ridley
At about 21 miles from central London, Ridley sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.
An inspection comes first for any ventilation job around Ridley, so the cleaning matches what’s there. If you manage a school such as Meopham School, ventilation cleaning is best booked for the holidays.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.

What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- Parking and loading at the site
- The size of the system
- A single visit or a regular plan
- Working hours and out-of-hours timing
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so there are no surprises.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Wide pictures of the system and the area around it
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- Any previous report or certificate
For AHU cleaning in Ridley, ring 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, and send photos or your last report if you can. A fixed quote typically follows within one working day.
How the visit works
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Ridley.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Move anything stored near the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet

Why act early in Ridley
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Our emergency line runs 24/7, but a planned visit to Ridley is calmer for everyone.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

Managing agents and facilities teams in Ridley
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
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. With shared responsibility, good records help everyone.
Ridley questions
Do you work overnight in Ridley?
Yes, out-of-hours work is a big part of what we do. The work in Ridley can fit around your hours. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Can you clean school ventilation in Ridley during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ridley. Just call us on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Do you have insurance?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Is there a report after cleaning?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
When something else is needed
To be straight with you, there are a few things this work will not fix:
- Airflow problems caused by the system’s design
