What happens on the day
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Aston, the date and timings are agreed with you well before the day.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Getting ready for the visit

About our AHU cleaning in Aston
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers supply and extract fans, heating and cooling coils and dampers and louvres, and common reasons people get in touch are dirty coils holding back the airflow and drain trays holding standing water.
In a village or hamlet like Aston, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
How the job changes from site to site
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
Aston: your questions answered
Will you come out to Aston?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can a school’s ventilation in Aston be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 17 schools and colleges on the FSA’s register within roughly a mile and a half of Aston, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711 or send us an email, and we’ll fit the work in.
What happens if you can’t reach some of it?
Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
Are you insured?
Yes. We are fully insured, and the details are available on request.
How long does an AHU clean take?
Typically the clean takes one overnight shift for many single units, with bigger plant phased. We plan the shutdown around that, including evenings or weekends.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will usually reply within one working day.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
Aftercare tips
Looking after the system between visits is straightforward, and it helps at the next visit:
- Look at the condensate drain whenever the unit is serviced
- Watch for drips or damp patches near the plant
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

Why act early in Aston
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Systems in rural buildings are often out of sight and out of mind.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

AHU cleaning in Aston: local notes
There are about 17 schools, colleges and universities and about 7 care, childcare and hospital premises on the FSA’s food hygiene register in Aston and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. We cover Aston, about 27 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Aston’s nearest hospital, Lister Hospital, is about 3.6 miles north-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Healthcare ventilation, from large hospitals like Lister Hospital (about 3.6 miles north-west) to small clinics, depends on clean filters, coils and ducts. If you manage a school such as Aston St Mary's Church of England Aided Primary School, ventilation cleaning is best booked for the holidays.
Aston is about 2 miles south-east of Stevenage, in Hertfordshire. We carry out AHU cleaning for businesses, landlords and public buildings in Aston and the rest of Hertfordshire. Across Hertfordshire, we cover 381 places, and Aston is one of them. London is in our area too, around 27 miles away.
AHU cleaning in SG2 follows the same survey, fixed quote and written report as everywhere else we cover. We cover sites on Penn Close, Benington Road and Brook Field and the roads around them. If your site is just outside Aston, we cover Bragbury End (1 mile south), Shephall (1 mile west), Hook's Cross (1 mile south), Benington (2 miles east) and Knebworth (2 miles south-west). Further out, we also cover St Albans (12 miles south-west), Bishop's Stortford (13 miles east), Welwyn Garden City (7 miles south), Harpenden (10 miles south-west), Hitchin (7 miles north-west) and Hoddesdon (11 miles south-east).
Around Aston
We work in commercial kitchens and buildings around The Heathcote School, Rose And Crown Public House and Barnwell School, among other places. Aston’s nearest station is Knebworth station, roughly 2.2 miles south-west. Other landmarks nearby include Benington Castle (1.5 miles east) and Stevenage Museum (2.3 miles north-west). Not far away are Ridlins Mire.
Managing agents and facilities teams in Aston
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Honest limits
Before booking, it helps to know what’s not included:
- Airflow problems caused by the system’s design
- Faulty motors, drives or bearings
- Building management system faults
If you’re not sure, just phone us on 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.
