What AHU cleaning looks like in Freeland
Food Standards Agency records list about 4 caring premises (care homes, nurseries and hospitals) registered as food businesses in and around Freeland, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Freeland is about 60 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
Classrooms and halls at schools such as Freeland Church of England Primary School are easiest to work in when pupils are away.

AHU cleaning in Freeland
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with units that have only ever had filter changes and debris and leaves in the fresh air intake, we can help.
In a village or hamlet like Freeland, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

When it’s something else
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Damaged coils beyond cleaning
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think before you book.
What we work on in Freeland
- Internal panels
- Drain trays
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
- Filter sections
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Change filters on schedule and log each change
- Make sure the unit’s access doors open easily
- Store the TR19 paperwork where auditors can find it
- Look at the condensate drain whenever the unit is serviced
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.

Questions from Freeland
Is Freeland within the area you cover?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Freeland?
Yes, we can come after you close and finish before you open. The work in Freeland can fit around your hours. Let us know the hours you are closed and we will book within them.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Will the ventilation be off while you clean?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
Is a quote from pictures possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Signs you need AHU cleaning in Freeland
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and that is where slime and odours start.
These are the problems we see most often:
- Filters that are clogged or overdue
- Units that have only ever had filter changes
- Debris and leaves in the fresh air intake
- Drain trays holding standing water
In Freeland, we look inside the system before deciding what needs cleaning.
Before you book anyone
- Proof of accreditation you can verify
- What paperwork you get at the end
- What insurance they carry
- Whether the figure could change on the day
What affects the quote in Freeland
The survey tells us what the work involves. The main factors are:
- The times the site is available
- How many systems or sites are involved
- Travel, parking and unloading
- The size of the system
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.
Helping us quote
To speed up the quote, please include:
- Your last certificate, test record or report
- The site address and the type of premises
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
To get a fixed quote, call us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. Visits to a village like Freeland are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Find the previous report, if there is one
- Make sure someone can let us in and lock up afterwards
- Let us know about permits to work or site inductions

Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
