AHU cleaning across Fawkham Green

Part by part

Filters

Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.

Drain trays

Older trays can corrode and start leaking. We record their condition with photos so you can decide on any repairs.

About our AHU cleaning in Fawkham Green

Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers internal panels, filter sections and drain trays, and people most often call us about dust-coated heating and cooling coils and dirty filters cutting the airflow.

Somewhere as small as Fawkham Green, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Why it’s worth doing now in Fawkham Green

Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Rural sites cannot always move to another kitchen or room when something fails.

Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

Honest limits

We’d rather tell you now than book work that won’t help, so here are the limits:

  • A system that is undersized for the building
  • The supply and extract ducts, quoted separately
  • Faulty motors, drives or bearings

If in doubt, call 0345 646 2711 or drop us a line and we will say what we think.

Where we work

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

The process

We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. Visits to a village like Fawkham Green are booked in advance, at a time that suits whoever runs the site.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. The unit is closed up and handed back, with a report to follow.

Getting ready for the visit

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Name a contact who can let us in at the agreed time
  • Allow time for equipment near the work to be turned off and cool down

Common problems we fix in Fawkham Green

Whatever surrounds a building in Fawkham Green, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.

Look out for these warning signs:

  • Filters that are clogged or overdue
  • Odours coming through the supply air
  • Air handling units never cleaned inside
  • Dust built up on fan impellers

For schools like New Ash Green Primary School, the holidays are the usual time to inspect and clean ventilation.
