What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before we start.
What we need to know
Before you ask for a quote, gather:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
AHU cleaning for kitchens and businesses in Lyford
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Clearing and cleaning the tray is central to every AHU clean. Typical jobs include drain trays holding standing water and intake sections clogged with outdoor debris, across internal panels, dampers and louvres and heating and cooling coils.
Somewhere as small as Lyford, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

AHU cleaning around Lyford
The nearest hospital to Lyford is Abingdon Community Hospital, about 6 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Lyford is about 58 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.
In Lyford, we look inside the system before deciding what needs cleaning. Healthcare ventilation, from large hospitals like Abingdon Community Hospital (about 6 miles east) to small clinics, depends on clean filters, coils and ducts.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
When it’s something else
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Breakdowns that need a mechanical engineer
- Coils that are corroded or leaking and need replacing
- Controls and BMS settings that run the unit
If in doubt, ring 0345 646 2711 or send us an email and we’ll say what we think before booking.
Parts of the system we cover

Managing agents and facilities teams in Lyford
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.

Part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. 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 will not bend or flatten the fins.
FAQs for Lyford
Do you work overnight in Lyford?
Yes. We work evenings, overnight and at weekends. It means the site in Lyford keeps running as normal. Just give us a ring 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 Lyford?
Yes. We work across London and the South East, and Lyford is part of that. Just ring 0345 646 2711 or send us an email with a few details of the site.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Is a quote from pictures possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. A fixed quote follows.
How it works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. Somewhere like Lyford, lanes, gates and parking are worth mentioning in advance.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
Get a fixed 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. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Keeping the system healthy
To keep the system working properly between visits:
- Make sure condensate is draining away
- Book the next check in line with the report
- Keep filter changes on time and recorded
- Store the TR19 paperwork where auditors can find it
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
