About our AHU cleaning in Brattle

Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you have air handling units due a clean after building work and units that have only ever had filter changes, we can help, from supply and extract fans, dampers and louvres and heating and cooling coils onwards.

Work in a small place like Brattle starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.

Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Your questions about AHU cleaning in Brattle

Can the work in Brattle be done at night or at weekends?

Yes, nights and weekends are routine for us. It means the site in Brattle keeps running as normal. Just ring 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.

Do you clean school ventilation in Brattle in the holidays?

Yes, holiday work suits schools best. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Brattle. Booking early in the term gives the best choice of holiday dates.

Will we get paperwork for the AHU clean?

Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.

How long will the unit be out of action?

Typically the clean takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, out of hours if needed.

Can you fix a faulty AHU?

We clean the unit and flag faults rather than repair them, with pictures where it helps.

What do you do with what you remove?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and we will quote them together.

Can you price the work without visiting?

Typically, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If pictures are not enough, we will survey first.

Why deal with it now?

Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Planning a trip to Brattle ahead is easier for everyone than a rushed one.

You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

In-house cleaning or a specialist?

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.

Common problems we fix in Brattle

Whatever surrounds a building in Brattle, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.

The symptoms we are asked about most are:

  • Plant that has been serviced but not cleaned
  • Coils clogged with dust and debris
  • Drain trays holding standing water
  • Dirty fans and fan housings

In Brattle, we look inside the system before deciding what needs cleaning.

Before booking anyone

  • Whether VAT is included
  • Whether the quote is based on a survey or pictures
  • Proof of accreditation you can verify
  • How they set the interval to the next visit

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. Somewhere as small as Brattle, the date and timings are agreed with you well before the day.

  1. We agree a shutdown window that suits the building.
  2. We take before pictures of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  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

  • Tell us the best time to work, such as after service or at a weekend
  • Name a contact who can let us in at the agreed time
  • Let us know about parking and loading

Ask for a quote

Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

When something else is needed

An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:

  • Mechanical faults with motors, belts or bearings
  • Problems with the unit’s controls or sensors
  • Ductwork downstream of the unit, which is a separate clean

If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think.

Parts of the system we cover

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

Landlords, agents and facilities managers

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

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 the report can go to both.

Keeping the system healthy

Think of this as the after-treatment advice, short and simple:

  • Note any water around the unit or leaks below it
  • File each AHU report in the maintenance log
  • Make sure the unit’s access doors open easily
  • Keep filter changes on time and recorded

The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
