AHU cleaning for kitchens and businesses in Four Oaks

Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. Typical jobs include coils clogged with dust and debris and fan sections that haven’t been cleaned in years, across drain trays, heating and cooling coils and filter sections.

Somewhere as small as Four Oaks, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.

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

Busy, occupied buildings like these are where clean supply air matters most. At about 43 miles from central London, Four Oaks sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.

Why deal with it now?

Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Our emergency line runs 24/7, but a planned visit to Four Oaks is calmer for everyone.

A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You will have a fixed price before we start.

What you get with us

  • CHAS and SafeContractor accredited, with ISO 9001
  • We diagnose before we treat
  • Fixed quotes from a survey or pictures
  • Work around your opening hours, with 24/7 emergency cover

Signs you need AHU cleaning in Four Oaks

Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.

Any of these means the system needs a check-up:

  • Dirty filters cutting the airflow
  • Intake sections clogged with outdoor debris
  • Dust-coated heating and cooling coils
  • Drain trays holding standing water

For schools like Luddenham School, the holidays are the usual time to inspect and clean ventilation.

What to look for in a quote

  • Whether the price is fixed
  • If they look at the system before pricing
  • What’s included in the scope, part by part
  • Whether the work can be done while the site is closed

Our hiring checklist

What we do, step by step

The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes one overnight shift for many single units, with bigger plant phased, and the area is cleaned down before we leave. In a small place like Four Oaks, the journey is planned ahead and the visit arranged around the site’s hours.

  1. We survey the unit from pictures or on site and agree what’s included.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

Preparing for the visit

  • Arrange a key holder or contact on site
  • Tell us the best time to work, such as after service or at a weekend
  • Clear loose items from the work area

Managing agents and facilities teams in Four Oaks

We also work for facilities teams across offices, schools and healthcare across Kent. Larger estates can be phased building by building around the people who use them.

If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

Different parts, different methods

Drain trays

Drain trays can rust and leak over time. We record their condition with photos so repairs can be planned.

Filters

Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.

What your team can do, and what needs us

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.

Day-to-day cleaning is something your team can do: 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, which is where we come in.

Four Oaks: your questions answered

Do you work overnight in Four Oaks?

Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.

Do you clean school ventilation in Four Oaks in the holidays?

Yes, out-of-term visits are normal for schools. Around Four Oaks, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you ring 0345 646 2711 or use the quote form, and we’ll fit the work in.

What do you do to protect the area?

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

Can you set up regular visits?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.

How often do AHUs need cleaning?

It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and the report recommends a next date.

What does AHU cleaning cost?

Every site is different, so each gets its own fixed quote. For a quote, give us a ring on 0345 646 2711 or email us and tell us about the site and its opening hours.

What’s included in an AHU clean?

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

Does the AHU have to be shut down for cleaning?

Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
