FAQs for Speen
Do you cover smaller places like Speen?
Yes. Speen is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Can the work in Speen be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Speen needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with the details in the report.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
How long does an AHU clean take?
Expect it to take one overnight shift for many single units, with bigger plant phased. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
AHU cleaning in Speen
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with air handling units with blocked filters and condensate trays that won’t empty, we can help, from heating and cooling coils, supply and extract fans and drain trays onwards.
In a village or hamlet like Speen, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Different parts, different methods
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.
Honest limits
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- A system that is undersized for the building
- Ductwork downstream of the unit, which is a separate clean
- Damaged coils beyond cleaning
If in doubt, phone us on 0345 646 2711 or send us an email and we’ll say what we think before you book.

When to call us in Speen
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Any of these means the system needs a check-up:
- Units needing a clean before a new tenant or handover
- Blocked condensate drains and slimy trays
- Units that have only ever had filter changes
- Air handling units with blocked filters

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
How it works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. In a small place like Speen, the journey is planned ahead and the visit arranged around the site’s hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Move anything stored near the system
- Dig out any earlier paperwork for the system

Why act early in Speen
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. In a place like Speen, ductwork and fans are easy to forget until something goes wrong.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
