AHU cleaning in Penton Hook, done properly

Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Typical jobs include fan sections that haven’t been cleaned in years and intake sections clogged with outdoor debris, on dampers and louvres, drain trays and supply and extract fans.

In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re 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.

How it works

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. A few pictures of the system help us make the most of a visit to a place like Penton Hook.

  1. First the unit is surveyed, from photos or a visit, and the scope agreed.
  2. The unit is shut down with your site team and the area protected.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. You get a TR19® certificate and a photo report.

Getting ready for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Plan for cooking equipment or plant to be off before we arrive
  • Make sure someone can let us in and lock up afterwards

How to get a quote

We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, call us on 0345 646 2711, or email photos.

Advice

What your team can do, and what needs us

Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.

Looking after it afterwards

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Keep filter changes on time and recorded
  • Diary the inspection date recommended in the report
  • Flag stale or damp smells in the supply air
  • Watch for drips or damp patches near the plant

We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.

Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

How the job changes from site to site

Filters

Filter condition tells you a lot about the rest of the unit. We photograph them for the report.

Fans and fan sections

Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.

Ventilation in Penton Hook buildings

The FSA’s food hygiene register lists about 12 schools, colleges and universities and about 9 care, childcare and hospital premises with registered kitchens or food service in Penton Hook and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. We cover Penton Hook, about 19 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Runnymede Hospital is the nearest hospital, about 2.3 miles south-west of Penton Hook. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

Healthcare buildings such as Runnymede Hospital, about 2.3 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Penton Hook, yours matters too. Classrooms and halls at schools such as Laleham CofE VA Primary School are easiest to work in when pupils are away.

What AHU cleaning cannot fix

Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It won’t put right:

  • Airflow problems caused by the system’s design
  • Leaking heating or cooling coils
  • Mechanical faults with motors, belts or bearings

If you’re not sure, just ring 0345 646 2711 or send us an email and we will give you a straight answer before you book.

Where we work

  • Heating and cooling coils
  • Dampers and louvres
  • Supply and extract fans
  • Internal panels
  • Drain trays
  • Filter sections

How we price AHU cleaning

The survey tells us what the work involves. The main factors are:

  • Where the site is and how we reach it
  • How many systems or sites are involved
  • The scale of the work
  • When the work can happen, such as evenings, overnight or weekends

You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or drop us a line, and we will talk you through it.

Asking for a quote

We can often survey from photos. The most useful are:

  • Your last certificate, test record or report
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Close-ups of filters, grilles, hatches or access panels
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Why act early in Penton Hook

A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. With notice, the visit to Penton Hook can be fitted around your bookings and events.

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 we start, so you know where you stand.

Why book with us

  • Fixed quotes, normally within one working day
  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • CHAS, SafeContractor and ISO 9001
  • Survey first, then a fixed quote

Your questions about AHU cleaning in Penton Hook

Can a school’s ventilation in Penton Hook be done out of term time?

Yes, holiday work suits schools best. Food Standards Agency records list about 12 schools, colleges and universities with registered kitchens within about a mile and a half of Penton Hook. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.

Can the work in Penton Hook be done at night or at weekends?

Yes. We work evenings, overnight and at weekends. The work in Penton Hook can fit around your hours. Tell us your opening hours when you ask for a quote.

Do you repair air handling units?

The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.

What do you clean inside the unit?

Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.

Is there a report after cleaning?

Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.

How much notice do you need?

For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.

How long will the unit be out of action?

As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, including evenings or weekends.

Do you clean the ductwork as well?

Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. It’s often worth doing both at once, and we can survey both on the same visit.
