AHU cleaning near Grafty Green

Keeping the system healthy

How long the results last depends on use and care. Here’s what we suggest:

  • Look at the condensate drain whenever the unit is serviced
  • Diary the inspection date recommended in the report
  • Note any water around the unit or leaks below it
  • Stick to the filter change plan

The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.

Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

AHU cleaning in Grafty Green, done properly

Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you are dealing with odours coming through the supply air and dirty coils holding back the airflow, we can put it right.

In a village or hamlet like Grafty Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.

For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Signs you need AHU cleaning in Grafty Green

Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.

What we are most often called out for:

  • Units needing a clean before a new tenant or handover
  • Blocked condensate drains and slimy trays
  • Odours coming through the supply air
  • Leaves and litter drawn into the unit

Around Grafty Green, as anywhere, ventilation cleaning begins with an inspection.

Our hiring checklist

How it works

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Grafty Green.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After pictures are taken and the certificate issued.

Preparing for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Clear loose items from the work area
  • Make sure equipment near the work can be switched off and left to cool

Your questions about AHU cleaning in Grafty Green

Do you cover smaller places like Grafty Green?

Yes. Grafty Green is within the area we cover across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is Grafty Green in your area for AHU cleaning?

Yes. Our area runs across London and the South East, Grafty Green included. You can phone us on 0345 646 2711, or send details by email and let us know what needs doing.

What does AHU cleaning cost?

Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.

What if parts of the system can’t be reached?

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

Does the AHU have to be shut down for cleaning?

Yes, for the time we’re working on it. Out-of-hours work is available to keep disruption down.

Are you insured?

Yes. Duct Doctor is fully insured, and we can share the details when you need them.

Can you fix a faulty AHU?

AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.

What should I send you?

The site address, the type of premises and your opening hours, plus pictures of the system and your last certificate or report if you have one.

Part by part

Rooftop and plant room units

Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.

Internal casing and panels

Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.

What a clean will not put right

To be straight with you, some problems need a different fix:

  • Coils that are corroded or leaking and need replacing
  • Airflow problems caused by the system’s design
  • Problems with the unit’s controls or sensors

If in doubt, ring 0345 646 2711 or send us an email and we will say what we think.

Parts of the system we cover

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

What happens if it’s left?

Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. In a small place like Grafty Green, a system that fails can take a site out of use.

You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711, or send details by email, and we’ll explain what it covers.

What you get with us

  • A written report with photos after each visit
  • CHAS and SafeContractor accredited, with ISO 9001
  • Work around your opening hours, with 24/7 emergency cover
  • We’re fully insured
