Tring: your questions answered
Can the work in Tring be done at night or at weekends?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Can you clean school ventilation in Tring during the holidays?
Yes, holiday work suits schools best. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Tring, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
AHU cleaning in Tring, done properly
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. If you are dealing with dirty filters cutting the airflow and rooms that smell stuffy when the system runs, we can help.
For a building near Tring, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Good records are part of the job. You get a written report with photos after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Common problems we fix in Tring
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Keep an eye out for these warning signs:
- Coils clogged with dust and debris
- Plant that has been serviced but not cleaned
- Condensate trays that will not empty
- Dirty filters cutting the airflow
If you run a surgery, dental practice or care home near Tring, clean ventilation matters as much to you as to a hospital like Stoke Mandeville Hospital (about 5.9 miles west).
What to look for in a quote
- When the next visit should be, and why
- Whether the figure could change on the day
- Which accreditations they hold, and whether you can check them
- How VAT is shown on the quote
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. It’s better to plan the work at a site near Tring than wait for a failure.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

What staff can safely do
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
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 can diagnose it and quote.
What a clean won’t put right
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It won’t put right:
- Breakdowns that need a mechanical engineer
- Airflow problems caused by the system’s design
- Building management system faults
If you’re not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
What we work on in Tring
- Heating and cooling coils
- Filter sections
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Internal panels
Different parts, different methods
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
What else we do in Tring
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep inspection doors on the unit in good order
- Watch for drips or damp patches near the plant
- Report musty smells from the vents straight away
- Make sure condensate is draining away
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes one overnight shift for many single units, with bigger plant phased. Your opening hours decide when we come to Tring, not ours.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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.
Preparing for the visit
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
How to get a quote
We don’t publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To get going, call 0345 646 2711, or send details by email.
