AHU cleaning for kitchens and businesses in Braughing

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. If you have filters that are clogged or overdue and dust-coated heating and cooling coils, we can help, from drain trays, internal panels and dampers and louvres onwards.

In a village or hamlet like Braughing, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Aftercare tips

Simple habits between visits make a real difference. We recommend:

  • Do not store bins or materials near the intake
  • Check the drain tray is emptying during routine visits
  • Diary the inspection date recommended in the report
  • Don’t ignore odours coming through the grilles

You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.

Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.

What AHU cleaning can’t fix

Not every problem is solved by AHU cleaning, and we’d rather say so up front. It will not put right:

  • Ventilation that was badly designed in the first place
  • Problems with the unit’s controls or sensors
  • Mechanical faults with motors, belts or bearings

Not sure which it is? You can call 0345 646 2711, or email photos and we’ll tell you honestly.

What we work on in Braughing

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

Common problems we fix in Braughing

Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.

It’s time to book a visit if you see:

  • Dirty fans and fan housings
  • Air handling units due a clean after building work
  • Plant that has been serviced but not cleaned
  • Dirty filters cutting the airflow

Wherever a school like Jenyns First School and Nursery has ducted ventilation, a half-term visit keeps the work out of lesson time.

Our hiring checklist

Why deal with it now?

When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Our emergency line runs 24/7, but a planned visit to Braughing is calmer for everyone.

The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.

What you get with us

  • A written report with pictures after each visit
  • Full insurance on every job
  • CHAS, SafeContractor and ISO 9001
  • A fixed price before any work starts

Braughing: your questions answered

Can you come to Braughing after we close?

Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.

Will you come out to Braughing?

Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.

Is there a report after cleaning?

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

What if parts of the system cannot be reached?

They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.

How much does AHU cleaning cost in Braughing?

There’s no set price, as it 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 we start.

Where does the waste go?

Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.

Do you survey before quoting?

Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.

What types of premises do you cover?

All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.

Different parts, different methods

Internal casing and panels

Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.

Heating and cooling coils

Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.

What we do, step by step

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send pictures, we can arrive in Braughing knowing what to expect.

  1. We agree a shutdown window that suits the building.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. The fan and drain tray are cleaned and the drain checked.
  5. We take after photos and issue the certificate and report.

Before we arrive

  • Let us know about parking and loading
  • Find the previous report, if there is one
  • Allow time for equipment near the work to be turned off and cool down

Ask for a quote

What your team can do, and what needs us

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
