AHU cleaning in Standon Green End, done properly
Where a building in Standon Green End has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for debris and leaves in the fresh air intake and fan sections that haven’t been cleaned in years, on drain trays, filter sections and supply and extract fans.
Work in a small place like Standon Green End starts with agreeing access and timings.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Common problems we fix in Standon Green End
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray does not fall properly, water stands in it, and slime and smells soon follow.
The symptoms we are asked about most include:
- Plant that needs cleaning after a refit
- Leaves and litter drawn into the unit
- Units that have only ever had filter changes
- Odours coming through the supply air
Hertford County Hospital, about 5.2 miles south-west, is the nearest hospital to Standon Green End, and healthcare sites of every size need their supply air kept clean.

What your team can do, and what needs us
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 is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Managing agents and facilities teams in Standon Green End
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Rural roads and tight entrances are worth telling us about before a visit to Standon Green End.
- 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.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Agree a time when the area can be out of use
- Let us know about permits to work or site inductions
- Clear loose items from the work area
How to get a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.

How often should an air handling unit be cleaned?
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.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
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.
Do you survey before quoting?
Yes. We always survey first, either from photos and details you send or on a site visit. A fixed quote follows.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Are you insured?
Yes. We are fully insured, and the details are available on request.
How we price AHU cleaning
You will get a fixed price before we start. It takes into account:
- The condition we find in the survey
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
Asking for a quote
When you contact us, these details help:
- Wide pictures of the system and the area around it
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Keeping the system healthy
So the system stays in good health:
- Stick to the filter change plan
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
- Diary the inspection date recommended in the report
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.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
