About our AHU cleaning in Bocking

A cooling coil drips condensate into a tray that should drain away. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers internal panels, supply and extract fans and dampers and louvres, and people most often call us about units needing a clean before a new tenant or handover and intake sections clogged with outdoor debris.

Smaller buildings around Bocking often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.

The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

When it’s something else

A few issues sit outside what this work can do:

  • Ventilation that was badly designed in the first place
  • Faulty motors, drives or bearings
  • Dirty ducts beyond the unit itself

If in doubt, ring 0345 646 2711 or use the quote form and we will say what we think.

Why it’s worth doing now in Bocking

Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Booking now means the visit to Bocking is planned around you, not forced by a breakdown.

Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

Why Bocking businesses choose us

  • Survey first, then a fixed quote

Aftercare tips

Results last longer with the right care. Here’s what we suggest:

  • Keep inspection doors on the unit in good order
  • Look at the condensate drain whenever the unit is serviced
  • Plan the next inspection before the last report gets filed away
  • Report musty smells from the vents straight away

You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.

Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.

Fixed quotes for AHU cleaning in Bocking

Before we fix a price, we need to know a few things. We check:

  • When the work can happen, such as evenings, overnight or weekends
  • Site requirements such as sign-in and permits
  • Travel, parking and unloading
  • How many systems or sites are involved

Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.

Helping us quote

To help us quote quickly, send us:

  • Photos showing the whole system and its surroundings
  • The roof, plant room or outside wall the system runs to
  • The site address and the type of premises
  • Your opening hours and when the area is out of use

To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Then ring 0345 646 2711 or use the quote form.

How the job changes from site to site

Heating and cooling coils

A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.

Filters

Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.

Common questions in Bocking

Can you get to a site in Bocking?

Yes. Villages and rural sites across the South East are part of our work, Bocking included. Let us know about access, parking and anything unusual about getting there when you book.

Do you work at weekends in Bocking?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

How much does AHU cleaning cost in Bocking?

We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.

Can one contract cover all our sites?

Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.

What types of premises do you cover?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.

Will you repair the fan or motor?

Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.

Can you come out in an emergency?

Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.

How long does an AHU clean take?

Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, out of hours if needed.

How it works

We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. In a place like Bocking, we fit the visit around your hours.

  1. The survey covers the unit, its access and how it can be shut down.
  2. The area is protected and the unit made safe.
  3. Each section is cleaned of dust, debris and slime.
  4. We clean the coils and clear the tray and drain.
  5. The unit is closed up and handed back, with a report to follow.

Preparing for the visit

  • Plan for cooking equipment or plant to be off before we arrive
  • Dig out any earlier paperwork for the system
  • Let us know about parking and loading

Getting a quote

For a fixed quote, give us a ring on 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You will typically have a quote within one working day.

Do you need AHU cleaning in Bocking?

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.

What we are most often called out for:

  • Drain trays holding standing water
  • Air handling units due a clean after building work
  • Coils clogged with dust and debris
  • Dirty fans and fan housings

Healthcare buildings such as St Michael's Hospital, about 0.5 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Bocking, yours matters too.

Questions to ask before you book

  • Whether VAT is included
  • When they can work, and whether that is outside your opening hours
  • Which accreditations they hold, and whether you can check them
  • Exactly which parts of the system are covered
