AHU cleaning in Perry Vale, done properly
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. The work covers heating and cooling coils, filter sections and supply and extract fans, and common reasons people get in touch are plant that has been serviced but not cleaned and intake sections clogged with outdoor debris.
In London, plant rooms are often in basements or on roofs reached through occupied floors, so work in Perry Vale is often done in the evening or at weekends. Loading and parking are planned with the building first.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Perry Vale: your questions answered
Can ventilation in schools around Perry Vale be cleaned out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 42 schools and colleges with food registrations within roughly a mile and a half of Perry Vale. Send us your term dates when you ring 0345 646 2711, or send details by email, and we’ll fit the work in.
Can the work in Perry Vale be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you ring 0345 646 2711 or use the quote form, mention when the site is quiet.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Is a quote from pictures possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Which sectors do you work in?

Is Perry Vale in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Perry Vale.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
Do you repair air handling units?
Our AHU work is cleaning rather than mechanical repair. Any faults we notice are recorded so your maintenance contractor can deal with it.

What AHU cleaning looks like in Perry Vale
There are about 42 schools, colleges and universities and about 81 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register within roughly a mile and a half of the centre of Perry Vale. Busy, occupied buildings like these are where clean supply air matters most. In London, ventilation plant is often on the roof or below ground, so the work is normally done out of hours. For Perry Vale, the closest hospital is St Christopher's Hospice, roughly 1.1 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Workplaces around Forest Hill station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. If you manage a school such as Perrymount Primary School, ventilation cleaning is best booked for the holidays.

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 Perry Vale, that is air they breathe for hours at a time.
Signs it’s time to call us include:
- Stale or musty smells from the ventilation
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Blocked condensate drains and slimy trays

What affects the quote in Perry Vale
We do not publish a price list, because sites vary so much. What we look at:
- How many systems or sites are involved
- How big the system is
- Site rules, permits and inductions
- Travel, parking and unloading
The cost 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 there are no surprises.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Any access panels or hatches you can see
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.
Managing agents and facilities teams in Perry Vale
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What staff can safely do
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Staff cleaning doesn’t 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.
What happens on the day
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, which takes from a few hours for a compact unit to a day or more for a large one. Security desks and permits-to-work are routine in London, so let us know what your building in Perry Vale needs from us.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
For a fixed quote, phone us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll typically have a quote within one working day.
Advice
How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Internal casing and panels
We open each section through its doors and close them securely when we’re done before the unit is handed back.
