Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
If you notice any of these, it’s worth a diagnosis:
- Condensate trays that will not empty
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Coils clogged with dust and debris
Classrooms and halls at schools such as Hexton Junior Mixed and Infant School are easiest to work in when pupils are away.

How we handle AHU cleaning in Pegsdon
Our AHU cleaning covers sites in Pegsdon and the rest of Hertfordshire, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. We are often asked to deal with dirty filters cutting the airflow and plant that needs cleaning after a refit, across supply and extract fans, filter sections and heating and cooling coils.
Work in a small place like Pegsdon starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the cost of AHU cleaning
There’s no set price list, because sites vary so much. The quote depends on:
- Whether several sites go on one quote
- The size of the system
- One-off work versus a regular cycle
- The condition of the system
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or send details by email, and we will explain what it covers.
Helping us quote
You don’t need the technical terms. Just send:
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
For AHU cleaning in Pegsdon, give us a ring on 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
Different parts, different methods
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
How it works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a village like Pegsdon are booked in advance, at a time that suits whoever runs the site.
- 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.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
Get a fixed quote
For a fixed quote, phone us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.

AHU cleaning in Pegsdon: local notes
At about 34 miles from central London, Pegsdon sits well inside the area we cover. The visit is fixed around your opening hours, not ours. About 3.6 miles south-west of Pegsdon is Keech Hospice Care, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Hospitals such as Keech Hospice Care (about 3.6 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Pegsdon are no different.

Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, ready to show anyone who asks. Rural sites cannot always move to another kitchen or room when something fails.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or send details by email for straight advice and a fixed quote.

For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
What AHU cleaning cannot fix
We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Mechanical faults with motors, belts or bearings
- The supply and extract ducts, quoted separately
- Damaged coils beyond cleaning
If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think.
