How the job changes from site to site

Internal casing and panels

The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.

Drain trays

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

AHU cleaning in Chilmington Green

We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you are dealing with stale or musty smells from the ventilation and intake sections clogged with outdoor debris, we can help, from internal panels, drain trays and dampers and louvres onwards.

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

The paperwork matters as much as the work. You get a written report with pictures after every visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Leave it or put it right?

Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Somewhere as small as Chilmington Green, losing a kitchen or building to a fault is felt by everyone who uses it.

Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Chilmington Green questions

Do you work at weekends in Chilmington Green?

Yes. We work evenings, overnight and at weekends. It means the site in Chilmington Green keeps running as normal. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.

Can a school’s ventilation in Chilmington Green be done out of term time?

Yes, and it’s the easiest time to do it. With about 8 schools and colleges on the FSA’s register within roughly a mile and a half of Chilmington Green, it pays to plan holiday dates ahead. Just phone us on 0345 646 2711, or send details by email with your term dates and we will plan around them.

Do you repair air handling units?

AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.

Do you give a certificate after the clean?

Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.

What types of premises do you cover?

Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.

When should our AHU next be cleaned?

That is set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.

Do you need to switch the unit off?

Yes, for the time we are working on it. We can work evenings, overnight or at weekends to keep disruption down.

How much does AHU cleaning cost?

We do not 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 work begins.

What happens on the day

A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Chilmington Green before we set off.

  1. First the unit is surveyed, from photos 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. We close up the unit and send the certificate and before and after photos.

Before we arrive

  • Allow time for equipment near the work to be turned off and cool down
  • Find the previous report, if there is one
  • Clear loose items from the work area

Do you need AHU cleaning in Chilmington Green?

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.

Signs it’s time to call us include:

  • Dirty fans and fan housings
  • Plant that has been serviced but not cleaned
  • Dirty coils holding back the airflow
  • Debris and leaves in the fresh air intake

School buildings such as Great Chart Primary School are usually done in the holidays, so classrooms aren’t disturbed.

  • Whether the price is fixed
  • Whether a written report and photos are included
  • Whether the quote shows VAT

Choosing a duct cleaning contractor

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. That is our job.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
