Fryerning AHU cleaning
AHU cleaning in Fryerning from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Stale or musty smells from the ventilation
How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Fryerning.
- We look at the unit and the plant area during the survey.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
To get a fixed quote, ring 0345 646 2711 or drop us a line 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 typically come back within one working day.

AHU cleaning in Fryerning, done properly
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, internal panels and dampers and louvres, and the jobs we see most are dust built up on fan impellers and drain trays holding standing water.
In a village or hamlet like Fryerning, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Between visits
Good habits slow the build-up between visits. Our tips:
- Make sure the unit’s access doors open easily
- Watch for drips or damp patches near the plant
- Keep filter changes on time and recorded
- Don’t store bins or materials near the intake
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What a clean will not put right
Some problems need a different service or another trade:
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
- Ventilation that was badly designed in the first place
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly before booking.
Parts of the system we cover
- Supply and extract fans
- Internal panels
- Filter sections
- Heating and cooling coils
- Drain trays
- Dampers and louvres
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Fixed quotes for AHU cleaning in Fryerning
The price is fixed before any work begins. It’s based on:
- The size of the system
- When the work can happen, such as evenings, overnight or weekends
- The condition we find in the survey
- Any permits to work or inductions
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
Helping us quote
There’s no need for technical detail. Just send:
- Any access panels or hatches you can see
- Photos showing the whole system and its surroundings
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
How the job changes from site to site
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Why act early in Fryerning
If people in a building in Fryerning complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. A planned visit to Fryerning is easier to arrange than an emergency callout.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Fryerning questions
Do you cover smaller places like Fryerning?
Yes, Fryerning is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Can the work in Fryerning be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Fryerning needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
How long will the unit be out of action?
It takes half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
