AHU cleaning for sites in Letcombe Bassett

What staff can safely do

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

AHU cleaning in Letcombe Bassett, done properly

If the units serving a building in Letcombe Bassett have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. If you have rooms that smell stuffy when the system runs and filters that are clogged or overdue, we can help, from drain trays, heating and cooling coils and filter sections onwards.

For a building in or near Letcombe Bassett, access is agreed in advance and the visit is planned around the journey.

We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Letcombe Bassett is about 3 miles south-west of Wantage, in Oxfordshire. Letcombe Bassett gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos.

Questions from Letcombe Bassett

Do you offer AHU cleaning in Letcombe Bassett?

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

Do you work in villages like Letcombe Bassett?

Yes, Letcombe Bassett is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.

What should I send you?

Some pictures and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.

Do you have a 24/7 line?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

How often do AHUs need cleaning?

TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.

What types of premises do you cover?

Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.

Can one contract cover all our sites?

Yes. Tell us the addresses and what each needs and you will get one fixed quote.

What do you clean inside the unit?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.

Keeping the system healthy

Looking after the system between visits is straightforward, and it makes the next visit easier:

  • Report stiff or damaged access doors
  • File each AHU report in the maintenance log
  • Keep filter changes on time and recorded
  • Flag stale or damp smells in the supply air

The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.

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

Managing agents and facilities teams in Letcombe Bassett

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

When something else is needed

A few issues sit outside what this work can do:

  • Ventilation that was badly designed in the first place
  • Coils that are corroded or leaking and need replacing
  • Problems with the unit’s controls or sensors

Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.

Parts of the system we cover

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

What the work involves, part by part

Filters

Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.

Fans and fan sections

Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.

What we do, step by step

There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. If you can send pictures, we can arrive in Letcombe Bassett knowing what to expect.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. The unit is shut down with your site team and the area 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. We close up the unit and send the certificate and before and after pictures.

How to prepare

  • Let us know about permits to work or site inductions
  • Make sure equipment near the work can be switched off and left to cool
  • Agree a time when the area can be out of use

Getting a quote

There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or email us.

When to call us in Letcombe Bassett

Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.

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

  • Dust-coated heating and cooling coils
  • Leaves and litter drawn into the unit
  • Plant that needs cleaning after a refit
  • Air handling units never cleaned inside

Ventilation work in and around Letcombe Bassett is risk-based: inspect, then clean what needs it.

Questions to ask before booking

  • Whether a written report and pictures are included
  • How they set the interval to the next visit
  • Whether the quote is based on a survey or pictures
  • Whether they’re fully insured
