Fixed quotes for AHU cleaning in Durfold Wood

We do not publish a price list, because sites vary so much. The quote depends on:

  • What state the system is in
  • How many systems or sites are involved
  • How easy every part is to reach
  • Travel, parking and unloading

The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.

What to send for a quote

The more you tell us, the more accurate the quote. With your enquiry, please include:

  • A few general shots of the system
  • Problems your staff have spotted
  • Any previous report or certificate
  • Any access panels or hatches you can see

Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then ring 0345 646 2711 or use the quote form.

About our AHU cleaning in Durfold Wood

Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Typical jobs include drain trays holding standing water and dust-coated heating and cooling coils, across supply and extract fans, dampers and louvres and heating and cooling coils.

In a village or hamlet like Durfold Wood, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.

For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Durfold Wood questions

Will you come out to Durfold Wood?

Yes. Villages and rural sites across the South East are part of our work, Durfold Wood included. Just mention lanes, gates or anything else about the site when you book.

Can you work in Durfold Wood outside opening hours?

Yes, evening, overnight and weekend work is normal for us. The work in Durfold Wood can fit around your hours. Your opening times are the first thing we ask for.

Can you quote from pictures?

Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. Some sites still need a visit, and we will say so.

What does AHU cleaning cost?

We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.

What do you do with what you remove?

It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.

Will the ventilation be off while you clean?

Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.

What happens if you can’t reach some of it?

Anything we cannot reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.

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. We fit the work around how the site operates.

Looking after it afterwards

Aftercare is simple, and it helps at the next visit:

  • Keep inspection doors on the unit in good order
  • Keep filter changes on time and recorded
  • Don’t store bins or materials near the intake
  • Book the next check in line with the report

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.

Keep the area around the intake clear. What’s near the intake ends up in the unit.

Common problems we fix in Durfold Wood

Air handling units are typically tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.

The symptoms we are asked about most are:

  • Air handling units with blocked filters
  • Plant that has been serviced but not cleaned
  • Rooms that smell stuffy when the system runs
  • Debris and leaves in the fresh air intake

Hospitals such as Haslemere and District Hospital (about 5.8 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Durfold Wood are no different.

Questions to ask before booking

  • What records you will receive afterwards
  • Whether inaccessible sections are listed on the report
  • When they can work, and whether that’s outside your opening hours
  • If the quote is a fixed price or an estimate

Our hiring checklist

Multi-site and managed buildings

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

What staff can safely do

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.

Your own staff can handle the daily basics: 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.

What happens on the day

Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Seeing the system in pictures first means the trip to Durfold Wood can be planned properly.

  1. First the unit is surveyed, from pictures or a visit, and the scope agreed.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  3. Filters, coils, fan section and casing are cleaned in turn.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

Before we arrive

  • Mention any locked doors, roof access or ceiling voids
  • Dig out any earlier paperwork for the system
  • Let us know when the site is closed or quiet
