AHU cleaning in Lashenden
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. If you have blocked condensate drains and slimy trays and units that have only ever had filter changes, we can help, from drain trays, filter sections and supply and extract fans onwards.
For a building in or near Lashenden, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with photos so you can decide on any repairs.

What affects the cost of AHU cleaning
Sites vary more than people expect. The main factors:
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
- Parking and loading at the site
- How many systems or sites are involved
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
What to send for a quote
Before you ask for a quote, gather:
- The postcode and the type of business
- Any previous report or certificate
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Wide photos of the system and the area around it
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Do you need AHU cleaning in Lashenden?
It matters for two reasons: 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 Lashenden, that is air they breathe for hours at a time.
Any of these means the system needs a check-up:
- Debris and leaves in the fresh air intake
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
- Air handling units never cleaned inside
An inspection comes first for any ventilation job around Lashenden, so the cleaning matches what’s there.
What your quote should include
- How areas they cannot reach will be recorded
- If the quote is a fixed price or an estimate
- Whether the work can be done while the site is closed
- If they look at the system before pricing

When something else is needed
We will not sell you work that doesn’t address the problem, so these are the things it will not cover:
- Ductwork downstream of the unit, which is a separate clean
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer.

How it works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. Pictures of the system and its access let us plan the work in Lashenden before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down
- Mention any parking or loading restrictions
