AHU cleaning in Sheldwich Lees, done properly
A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, 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 supply and extract fans, drain trays and dampers and louvres, and people most often call us about dirty filters cutting the airflow and plant that has been serviced but not cleaned.
In a village or hamlet like Sheldwich Lees, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

What affects the quote in Sheldwich Lees
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Travel, parking and unloading
- How many systems or sites are involved
- Working hours and out-of-hours timing
- The condition of the system
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.

- Your last certificate, test record or report

- Any access panels or hatches you can see

Questions from Sheldwich Lees
Can you work in Sheldwich Lees outside opening hours?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Will you come out to Sheldwich Lees?
Yes, we work in villages as well as towns, and Sheldwich Lees is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, with new panels fitted where necessary.
Do you need to switch the unit off?
Yes, while the clean is under way. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
How much does AHU cleaning cost in Sheldwich Lees?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
How long does it take to clean an air handling unit?
It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we’ll quote them together.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Why it’s worth doing now in Sheldwich Lees
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. A planned visit to Sheldwich Lees is easier to arrange than an emergency callout.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

How the job changes from site to site
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
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 a clean won’t put right
AHU cleaning cannot fix everything, and we’ll tell you before any work starts. It won’t put right:
- Controls and BMS settings that run the unit
- Damaged coils beyond cleaning
- A system that is undersized for the building
If you’re not sure, just give us a ring on 0345 646 2711, or send details by email and we’ll give you a straight answer.
What the work covers
- Internal panels
- Heating and cooling coils
- Dampers and louvres
- Filter sections
- Drain trays
- Supply and extract fans
Landlords, agents and facilities managers
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 can quote for the whole system.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
The process
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Sheldwich Lees.
- 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.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
- Tell us about site rules, permits or sign-in

What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
