AHU cleaning for sites in Fernham

For landlords and multi-site operators

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

AHU cleaning for kitchens and businesses in Fernham

We clean air handling units for buildings in Fernham and across Oxfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We’re often asked to deal with odours coming through the supply air and drain trays holding standing water, on internal panels, dampers and louvres and supply and extract fans.

Work in a small place like Fernham starts with agreeing access and timings.

The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Looking after it afterwards

No system stays clean for ever, but care slows the build-up. Our tips:

  • Don’t ignore odours coming through the grilles
  • Report water on the plant room floor
  • Keep the area around the fresh air intake clear
  • File each AHU report in the maintenance log

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.

Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

How the visit works

At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Fernham, let us know and we’ll plan around it.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. We take before pictures of each section of the unit.
  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.

Preparing for the visit

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Tell us about site rules, permits or sign-in
  • Clear the space around the work

How to get a quote

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

Part by part

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.

Internal casing and panels

Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.

What AHU cleaning cannot fix

In fairness, some problems need a different fix:

  • Breakdowns that need a mechanical engineer
  • Controls and BMS settings that run the unit
  • Leaking heating or cooling coils

If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think before you book.

Where we work

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

Leave it or put it right?

A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Fernham simpler. A fault that closes a site in a village like Fernham affects everyone who depends on it.

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before any work starts.

How we price AHU cleaning

Sites vary more than people expect. What affects the quote:

  • Travel, parking and unloading
  • The number of sites or systems
  • What state the system is in
  • Whether we need access equipment or extra panels

The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

What we need to know

Many jobs can be priced from photos and some basics. Send what you can of the following:

  • A few general shots of the system
  • Your last certificate, test record or report
  • The times we could work without disrupting the site
  • Close-ups of filters, grilles, hatches or access panels

FAQs for Fernham

Is Fernham in your area for AHU cleaning?

Yes. We work across London and the South East, and Fernham is part of that. Get in touch with the details and we’ll arrange a survey.

Will you come out to Fernham?

Yes, we work in villages as well as towns, and Fernham is covered. A survey first, from pictures or a visit, means we arrive with the right kit.

Does the AHU have to be shut down for cleaning?

Yes, for the time we’re working on it. We can work evenings, overnight or at weekends so the building is not left without ventilation when it’s busy.

What’s TR19?

BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.

Do you work with multi-site operators?

Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.

What happens if you cannot reach some of it?

They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.

What happens to the waste?

We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.

How long does an AHU clean take?

It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
