AHU cleaning in Snow Hill, done properly
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Common call-outs are for air handling units never cleaned inside and leaves and litter drawn into the unit, across internal panels, drain trays and dampers and louvres.
For a building in or near Snow Hill, access is agreed in advance and the visit is planned around the journey.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Your questions about AHU cleaning in Snow Hill
Do you cover Snow Hill for AHU cleaning?
Yes. We work across London and the South East, and Snow Hill is part of that. A fixed quote normally follows within one working day of the survey details.
Is Snow Hill within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Snow Hill included. Let us know about access, parking and anything unusual about getting there when you book.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Will we get paperwork for the AHU clean?
Yes. A TR19® certificate and photo report are sent after the clean, with any faults we noticed.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.
What happens on the day
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Snow Hill, lanes, gates and parking are worth mentioning in advance.
- 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.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload
Getting a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, and then send you a fixed quote. To get going, call us on 0345 646 2711, or email photos.

Common problems we fix in Snow Hill
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
It’s time to book a visit if you see:
- Air handling units never cleaned inside
- Air handling units due a clean after building work
- Odours coming through the supply air
- Condensate trays that won’t empty
Healthcare ventilation, from large hospitals like Queen Victoria Hospital (about 3.7 miles east) to small clinics, depends on clean filters, coils and ducts.

Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Note any water around the unit or leaks below it
- Check the drain tray is emptying during routine visits
- Diary the inspection date recommended in the report
- Report musty smells from the vents right away
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
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.
When something else is needed
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Building management system faults
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
If you are not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer.
Parts of the system we cover

Leave it or put it right?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. Our emergency line runs 24/7, but a planned visit to Snow Hill is calmer for everyone.
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
