AHU cleaning for kitchens and businesses in Brookmans Park
Where a building in Brookmans Park has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Typical jobs include units that have only ever had filter changes and leaves and litter drawn into the unit, on dampers and louvres, heating and cooling coils and supply and extract fans.
For a building in or near Brookmans Park, 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.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When to call us in Brookmans Park
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Look out for these warning signs:
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
- Units that have only ever had filter changes
- Dirty coils holding back the airflow
School buildings such as Chancellor's School are usually done in the holidays, so classrooms are not disturbed.

In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

Fixed quotes for AHU cleaning in Brookmans Park
Sites vary more than people expect. The main factors:
- The number of sites or systems
- A single visit or a regular plan
- How easy every part is to reach
- What state the system is in
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Asking for a quote
There’s no need for technical detail. Just send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Aftercare tips
After the visit, a few habits help the work last:
- Do not store bins or materials near the intake
- Report musty smells from the vents right away
- Make sure the unit’s access doors open easily
- Change filters on schedule and log each change
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
When it’s something else
Some problems need a different service or another trade:
- Mechanical faults with motors, belts or bearings
- Coils that are corroded or leaking and need replacing
- Controls and BMS settings that run the unit
If in doubt, give us a ring on 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers
- Drain trays
- Internal panels
- Heating and cooling coils
- Filter sections
- Supply and extract fans

Multi-site and managed buildings
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 each one has its own record.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
The process
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. A quick note on how to find the site and where to park makes a visit to Brookmans Park run smoothly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- 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
- Dig out any earlier paperwork for the system
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
