AHU cleaning across Barford St John

When to call us in Barford St John

Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Barford St John, that is air they breathe for hours at a time.

Keep an eye out for any of the following:

  • Fan sections that haven’t been cleaned in years
  • Rooms that smell stuffy when the system runs
  • Intake sections clogged with outdoor debris
  • Dirty filters cutting the airflow

Healthcare buildings such as Horton General Hospital, about 4.2 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Barford St John, yours matters too.

Questions to ask before booking

AHU cleaning in Barford St John, done properly

The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. If you are dealing with dirty filters cutting the airflow and dirty fans and fan housings, we can help.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.

A written report with pictures follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works

Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to Barford St John.

  1. We survey the unit from photos or on site and agree what’s included.
  2. The unit is shut down with your site team and the area protected.
  3. Filters, coils, fan section and casing are cleaned in turn.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. We close up the unit and send the certificate and before and after photos.

Preparing for the visit

  • Agree a time when the area can be out of use
  • Mention any locked doors, roof access or ceiling voids
  • Clear the space around the work

Are you accredited?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.

Do you have a 24/7 line?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

Do you survey before quoting?

Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.

When should our AHU next be cleaned?

There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.

What the work involves, part by part

Rooftop and plant room units

Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey so the quote reflects it.

Filters

Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.

In-house cleaning or a specialist?

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.

Between visits

Here’s the after-treatment advice, in brief:

  • Plan the next inspection before the last report gets filed away
  • Do not store bins or materials near the intake
  • File each AHU report in the maintenance log
  • Stick to the filter change plan

Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.

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

Managing agents and facilities teams in Barford St John

Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
