About our AHU cleaning in Newyears Green
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you are dealing with plant that needs cleaning after a refit and odours coming through the supply air, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
The paperwork matters as much as the work. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Why act early in Newyears Green
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A planned visit to Newyears Green is easier to arrange than an emergency callout.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.

Newyears Green questions
Do you work overnight in Newyears Green?
Yes, we can come after you close and finish before you open. That way a site in Newyears Green does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you clean school ventilation in Newyears Green in the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Newyears Green. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
When should our AHU next be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report for your maintenance team to follow up.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
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 will take a look and send you a fixed quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
What the work involves, part by part
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Flag stale or damp smells in the supply air
- File each AHU report in the maintenance log
- Look at the condensate drain whenever the unit is serviced
- Plan the next inspection before the last report gets filed away
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

The process
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes one overnight shift for many single units, with bigger plant phased. A quick note on how to find the site and where to park makes a visit to Newyears Green run smoothly.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need

Signs you need AHU cleaning in Newyears Green
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
Common reasons sites call us include:
- Condensate trays that won’t empty
- Units that have only ever had filter changes
- Odours coming through the supply air
- Dirty fans and fan housings
Harefield Hospital, about 2.1 miles north-west, is the nearest hospital to Newyears Green, and healthcare sites of every size need their supply air kept clean.
