AHU Cleaning in Lyneham
AHU cleaning for businesses, landlords and public buildings in Lyneham. CHAS, SafeContractor and ISO 9001, and fully insured.
- Dust-coated heating and cooling coils
- Debris and leaves in the fresh air intake
- Stale or musty smells from the ventilation
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
About our AHU cleaning in Lyneham
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you have dust-coated heating and cooling coils and odours coming through the supply air, we can help.
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.
Each visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Somewhere as small as Lyneham, the date and timings are agreed with you well before the day.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
Advice
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
- Airflow problems caused by the system’s design
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly.

How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- How easy every part is to reach
- Parking and loading at the site
- Site requirements such as sign-in and permits
- The condition of the system
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.
Asking for a quote
We can often survey from photos. The most useful are:
- A few general shots of the system
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Where the site is and what kind of site it is
If you need AHU cleaning in Lyneham, phone us on 0345 646 2711 or drop us a line. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We usually send a fixed quote within one working day.

FAQs for Lyneham
Do you work overnight in Lyneham?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call us on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Can you do AHU cleaning in Lyneham?
Yes, Lyneham is within the area we cover across London and the South East. You can ring 0345 646 2711 or send us an email and tell us what needs doing.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
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.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Signs you need AHU cleaning in Lyneham
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
- Fan sections that haven’t been cleaned in years
- Dust-coated heating and cooling coils
Every job around Lyneham ends with a record of what was cleaned and what was found.
Questions to ask before booking
- How they set the interval to the next visit
- Whether the figure could change on the day
- What insurance they carry
- Exactly which parts of the system are covered
How the job changes from site to site
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Store the TR19 paperwork where auditors can find it
- Check the drain tray is emptying during routine visits
- Keep the area around the fresh air intake clear
- Stick to the filter change plan
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
