Lawrence Hill AHU cleaning

What the work involves, part by part
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
AHU cleaning in Lawrence Hill
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, internal panels and dampers and louvres, and the jobs we see most are stale or musty smells from the ventilation and drain trays holding standing water.
Around a place like Lawrence Hill, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s 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 work takes from a few hours for a compact unit to a day or more for a large one. Evenings, weekends or a closed day all work for a site in a place like Lawrence Hill.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Preparing for the visit
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Let us know about parking and loading

Advice
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Managing agents and facilities teams in Lawrence Hill
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
We also work for facilities teams across offices, schools and healthcare in Lawrence Hill and across Bracknell Forest. Work can be phased by floor, building or site around the people who use them.

Fixed quotes for AHU cleaning in Lawrence Hill
A fixed price needs a few facts first. We check:
- Any permits to work or inductions
- Where the site is and how we reach it
- The size of the system
- A single visit or a regular plan
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
What we need to know
We can often survey from photos. Try to include:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- The roof, plant room or outside wall the system runs to
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Lawrence Hill questions
Can the work in Lawrence Hill be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Can a school’s ventilation in Lawrence Hill be done out of term time?
Yes. The holidays are the usual time for school work. There are about 8 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Lawrence Hill. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, usually ready within one working day.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
When it’s something else
It’s worth knowing the limits before booking:
- Leaking heating or cooling coils
- Building management system faults
- A system that is undersized for the building
If you are not sure, just phone us on 0345 646 2711 or use the quote form and we will give you a straight answer before you book.

Leave it or put it right?
Stuffy rooms and stale smells in a building in Lawrence Hill can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. A visit arranged in advance is far less disruptive than a callout on a busy day.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
