- Air handling units due a clean after building work
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Oakhanger knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Tell us about site rules, permits or sign-in
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions
Getting a quote
Photos are the quickest way to a quote: 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.

AHU cleaning for kitchens and businesses in Oakhanger
No two plant rooms are the same, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. Typical jobs include air handling units with blocked filters and condensate trays that won’t empty, on drain trays, internal panels and heating and cooling coils.
For a building in or near Oakhanger, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Between visits
Aftercare is simple, and it helps at the next visit:
- Plan the next inspection before the last report gets filed away
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
- Keep inspection doors on the unit in good order
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Part by part
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.

What happens if it’s left?
Stuffy rooms and stale smells in a building in Oakhanger can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Somewhere as small as Oakhanger, losing a kitchen or building to a fault is felt by everyone who uses it.

When it’s something else
In fairness, some problems need a different fix:
- Problems with the unit’s controls or sensors
- Damaged coils beyond cleaning
- Ductwork downstream of the unit, which is a separate clean
If in doubt, call 0345 646 2711 or email us and we will say what we think.

What affects the quote in Oakhanger
You’ll get a fixed price before we start. It takes into account:
- How easy every part is to reach
- Travel, parking and unloading
- Site rules, permits and inductions
- The times the site is available
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
Helping us quote
We can often survey from pictures. Try to include:
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
- Wide photos of the system and the area around it
For AHU cleaning in Oakhanger, ring 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, and send photos or your last report if you can. We typically send a fixed quote within one working day.
In-house cleaning or a specialist?
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. 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’ll take a look and send you a fixed quote.
