When to call us in Loughton
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Loughton, that’s air they breathe for hours at a time.
These are the problems we see most often:
- Intake sections clogged with outdoor debris
- Dust-coated heating and cooling coils
- Stale or musty smells from the ventilation
- Condensate trays that won’t empty
School buildings such as Loughton Manor First School are normally done in the holidays, so classrooms are not disturbed.
What your quote should include
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the quote shows VAT
- Proof of insurance
- How they set the interval to the next visit
AHU cleaning for kitchens and businesses in Loughton
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. Typical jobs include filters that are clogged or overdue and units needing a clean before a new tenant or handover, on heating and cooling coils, filter sections and supply and extract fans.
In a place like Loughton, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Questions from Loughton
Is Loughton within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Loughton included. A survey first, from photos or a visit, means we arrive with the right kit.
Can the work in Loughton be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The work in Loughton can fit around your hours. Tell us your opening hours when you ask for a quote.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.

What a clean won’t put right
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Damaged coils beyond cleaning
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly.
What we work on in Loughton

The process
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. The work on site 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. Tell us about any gates, ladders or locked plant areas at your site near Loughton when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Tell us where we can park and unload
- Have your last certificate or report to hand
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

Different parts, different methods
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Fans and fan sections
Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.
Leave it or put it right?
Stuffy rooms and stale smells in a building in Loughton can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Light use slows the build-up but doesn’t stop it.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: 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.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
