Fixed quotes for AHU cleaning in West Heath
The diagnosis comes before the price. We look at:
- What state the system is in
- Travel, parking and unloading
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- Any access panels or hatches you can see
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call 0345 646 2711 or use the quote form.
About our AHU cleaning in West Heath
Our AHU cleans for sites in West Heath cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you’re dealing with drain trays holding standing water and air handling units never cleaned inside, we can put it right, from dampers and louvres, filter sections and internal panels onwards.
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 West Heath, 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. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
What the work involves, part by part
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Questions from West Heath
Can parking be tricky for a job in West Heath?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Can the work in West Heath be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The work in West Heath can fit around your hours. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Which sectors do you work in?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Do you work in West Heath?
Yes. West Heath is part of the area we cover, within the South East and London area we cover.
How long does an AHU clean take?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Change filters on schedule and log each change
- Watch for drips or damp patches near the plant
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

How it works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. In a London area like West Heath, parking, loading and building access are planned before the day of the work.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us the best time to work, such as after service or at a weekend
