AHU cleaning in Tyler's Hill, done properly
Where a building in Tyler's Hill has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you’re dealing with blocked condensate drains and slimy trays and dirty fans and fan housings, we can help, from dampers and louvres, heating and cooling coils and drain trays onwards.
Work in a small place like Tyler's Hill starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Why deal with it now?
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Systems in rural buildings are often out of sight and out of mind.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we will explain what it covers.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Change filters on schedule and log each change
- Check the drain tray is emptying during routine visits
- Do not store bins or materials near the intake
- Diary the inspection date recommended in the report
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
Tyler's Hill: your questions answered
Is Tyler's Hill within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Do you clean school ventilation in Tyler's Hill in the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 7 schools, colleges and universities with registered kitchens within about a mile and a half of Tyler's Hill. Just ring 0345 646 2711 or email us with your term dates and we’ll plan around them.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
When should our AHU next be cleaned?
That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Are you accredited?
Duct Doctor is 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.
How much notice do you need?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711 or use the quote form and tell us about the site and its opening hours.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, and new panels can be fitted.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. 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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
AHU cleaning around Tyler's Hill
Food Standards Agency records list about 7 schools, colleges and universities and about 8 caring premises (care homes, nurseries and hospitals) registered as food businesses within roughly a mile and a half of the centre of Tyler's Hill. Busy, occupied buildings like these are where clean supply air matters most. At about 25 miles from central London, Tyler's Hill sits well inside the area we cover. A survey and a fixed quote come first, then the visit at a time that suits you. About 3.4 miles south-west of Tyler's Hill is Amersham Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you manage a school such as Ley Hill School, ventilation cleaning is best booked for the holidays. If you run a surgery, dental practice or care home near Tyler's Hill, clean ventilation matters as much to you as to a hospital like Amersham Hospital (about 3.4 miles south-west).

What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. In a small place like Tyler's Hill, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
Preparing for the visit
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We consider:
- What state the system is in
- The size of the system
- Any permits to work or inductions
- The times the site is available
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before we start.

- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Problems your staff have spotted

How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
