About our AHU cleaning in Baldock
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. If you have fan sections that haven’t been cleaned in years and units needing a clean before a new tenant or handover, we can help, from filter sections, internal panels and dampers and louvres onwards.
For a building near Baldock, 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.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What else we do in Baldock
Keeping the system healthy
So the system stays in good health:
- File each AHU report in the maintenance log
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Keep inspection doors on the unit in good order
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
Do you need AHU cleaning in Baldock?
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Baldock, that’s air they breathe for hours at a time.
If you notice any of these, it’s worth a diagnosis:
- Odours coming through the supply air
- Dirty filters cutting the airflow
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
Workplaces around Baldock station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
Questions to ask before booking
- What’s included in the scope, part by part
- When they can work, and whether that is outside your opening hours
- Whether inaccessible sections are listed on the report
- Proof of insurance
How it works
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 anything from half a day for one small unit to several shifts for a plant room full of them. For a site near Baldock, the work is booked around your opening hours, evenings and weekends included.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids

Advice
What staff can safely do
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.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Why act early in Baldock
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. You choose the date of a planned visit, and a breakdown never asks.
What you pay depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
Why us?
- A written report with photos after each visit
- Full insurance on every job
- Ventilation hygiene specialists since 2009
- Out-of-hours work and a 24/7 emergency line

Questions from Baldock
Do you cover smaller places like Baldock?
Yes, Baldock is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you clean school ventilation in Baldock in the holidays?

Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
