AHU Cleaning in Chattenden
Air handling unit cleaning for businesses, landlords and public buildings in Chattenden. CHAS, SafeContractor and ISO 9001, and fully insured.
- Plant that has been serviced but not cleaned
- Stale or musty smells from the ventilation
- Condensate trays that will not empty
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
About our AHU cleaning in Chattenden
Our AHU cleaning covers sites in Chattenden and the rest of Medway, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have air handling units never cleaned inside and rooms that smell stuffy when the system runs, we can put it right.
In a village or hamlet like Chattenden, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We consider:
- Access, including roofs, risers and ceiling voids
- How big the system is
- Site rules, permits and inductions
- The condition we find in the survey
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
Asking for a quote
When you contact us, it’s useful to have:
- Any previous report or certificate
- A few general shots of the system
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.

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 the housing around them is cleaned too.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.
Chattenden questions
Do you clean school ventilation in Chattenden in the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 8 schools and colleges with food registrations within roughly a mile and a half of Chattenden. Booking early in the term gives the best choice of holiday dates.
Do you work in villages like Chattenden?
Yes, we work in villages as well as towns, and Chattenden is covered. Just mention lanes, gates or anything else about the site when you book.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What if parts of the system can’t be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Do you have insurance?
Yes. We are fully insured, and we can share the details when you need them.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Can you look after several sites?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
How long does it take to clean an air handling unit?
The work takes from a few hours for a compact unit to a day or more for a large one. Large plant can be split over several shifts, so ring 0345 646 2711 or send us an email to talk it through.
What happens if it’s left?
If people in a building in Chattenden complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. Out of sight is the usual reason a rural system goes too long without attention.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

What your team can do, and what needs us
When your team notices a problem 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 give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
AHU cleaning in Chattenden: local notes
Food Standards Agency records list about 8 schools, colleges and universities and about 7 hospitals, care homes and childcare premises registered as food businesses in Chattenden and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. For Chattenden, the closest hospital is French Hospital, roughly 2.4 miles south-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. At about 28 miles from central London, Chattenden sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you.
Wherever a school like Chattenden Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare ventilation, from large hospitals like French Hospital (about 2.4 miles south-west) to small clinics, depends on clean filters, coils and ducts.

The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes half a day to a full day per unit, with large plant planned over several shifts. In a small place like Chattenden, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- 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.
Getting ready for the visit
- Clear loose items from the work area
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Related advice
What AHU cleaning cannot fix
Not every problem is solved by AHU cleaning, and we’ll tell you before we start. It does not solve:
- Ductwork downstream of the unit, which is a separate clean
- Problems with the unit’s controls or sensors
- A system that’s undersized for the building
If you’re not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.
