What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
About our AHU cleaning in Hayes
Where a building in Hayes has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. Common call-outs are for dirty fans and fan housings and intake sections clogged with outdoor debris, across drain trays, internal panels and dampers and louvres.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Hayes, as elsewhere, cleaning starts with an inspection of what’s there.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Questions from Hayes
What do you need to know about parking in Hayes?
A loading bay, a visitor permit or off-street space near the site in Hayes makes the visit easier to plan. Working overnight, as we often do in London, usually makes it simpler.
Can the work in Hayes be done at night or at weekends?
Yes, nights and weekends are routine for us. The work in Hayes can fit around your hours. Your opening times are the first thing we ask for.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Can you quote from photos?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.
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.
How long does an AHU clean take?
Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Work can be phased by floor, building or site around the people who use them.
Signs you need AHU cleaning in Hayes
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
What we’re most often called out for:
- Dust-coated heating and cooling coils
- Air handling units with blocked filters
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
If you manage shops or offices close to Hayes & Harlington station, a TR19® Air inspection shows whether the ductwork needs cleaning.
What your quote should include
- Exactly which parts of the system are covered
- How VAT is shown on the quote
- Whether the work can be done while the site is closed
- When the next visit should be, and why
What affects the quote in Hayes
There’s no set price list, because sites vary so much. The quote depends on:
- The scale of the work
- The number of sites or systems
- Whether we need access equipment or extra panels
- Travel, parking and unloading
We don’t 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.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Any previous report or certificate
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
If you need AHU cleaning in Hayes, call us on 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, plus pictures or the previous report if they’re to hand. A fixed quote typically follows within one working day.
Looking after it afterwards
So the system stays in good health:
- File each AHU report in the maintenance log
- Do not ignore odours coming through the grilles
- Note any water around the unit or leaks below it
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Before any visit in Hayes, we agree where the van can stop and how equipment reaches the system.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend
Getting a quote
Photos are the quickest way to a quote: 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.
