AHU cleaning in Charing Heath
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Typical jobs include dirty fans and fan housings and units needing a clean before a new tenant or handover, across internal panels, drain trays and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Charing Heath: your questions answered
Do you do school ventilation cleaning in Charing Heath in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Charing Heath, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Do you work in villages like Charing Heath?
Yes. Charing Heath is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and clean down when we finish.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Leave it or put it right?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Rural sites cannot always move to another kitchen or room when something fails.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.

What else we do in Charing Heath
Different parts, different methods
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
When to call us in Charing Heath
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Clients typically contact us when they notice something like this:
- Dirty filters cutting the airflow
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
In Charing Heath, supply and extract ducts are cleaned along with the units that serve them.

Each visit runs to the same pattern: protect the area, make the system safe, do the work, clear away and leave you the report. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Charing Heath, let us know and we’ll plan around it.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Name a contact who can let us in at the agreed time
- Mention any parking or loading restrictions

Related advice
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and 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 is our job.
What affects the quote in Charing Heath
The survey tells us what the work involves. The main factors are:
- The size of the system
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- What state the system is in
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.
Asking for a quote
When you call or email, these details help:
- Your last certificate, test record or report
- Wide pictures of the system and the area around it
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or drop us a line.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
