AHU cleaning in Howe Hill, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you have debris and leaves in the fresh air intake and dust built up on fan impellers, we can help, from drain trays, supply and extract fans and dampers and louvres onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What affects the quote in Howe Hill
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many systems or sites are involved
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
- When the work can happen, such as evenings, overnight or weekends
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or email us, and we’ll talk you through it.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- 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
- Your last certificate, test record or report
To get a fixed quote, call us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will usually have a quote within one working day.
What the work involves, part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Howe Hill: your questions answered
Can you work in Howe Hill outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Do you work in villages like Howe Hill?
Yes, we work in villages as well as towns, and Howe Hill is covered. The journey is planned ahead, so a few details about the route help.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where necessary. Then you get a fixed quote.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
Are you insured?
Yes. We are fully insured, and the details are available on request.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Howe Hill and across Oxfordshire. Larger estates can be phased building by building to keep disruption down.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
When it’s something else
To be straight with you, some problems need a different fix:
- Damaged coils beyond cleaning
- Problems with the unit’s controls or sensors
- Dirty ducts beyond the unit itself
If in doubt, call us on 0345 646 2711, or email photos and we’ll say what we think before booking.
What the work covers
- Dampers and louvres
- Heating and cooling coils
- Filter sections
- Drain trays
- Internal panels
- Supply and extract fans
How the visit works
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 half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. For a village or hamlet like Howe Hill, tell us about narrow lanes, gates and parking when you book.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Find the previous report, if there is one
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload
Getting a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Aftercare tips
So the system stays in good health:
- Store the TR19 paperwork where auditors can find it
- Report musty smells from the vents right away
- Report stiff or damaged access doors
- Note any water around the unit or leaks below it
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
