How we handle AHU cleaning in Cores End

We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include dirty fans and fan housings and air handling units due a clean after building work, across heating and cooling coils, dampers and louvres and drain trays.

Somewhere as small as Cores End, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site

Fans and fan sections

Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.

Filters

What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.

Common questions in Cores End

Do you work overnight in Cores End?

Yes, evening, overnight and weekend work is normal for us. That way a site in Cores End does not have to lose a day’s trading. Let us know the hours you are closed and we will book within them.

Will you come out to Cores End?

Yes. Cores End is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.

Are you fully insured?

Yes. Duct Doctor is fully insured, and the details are available on request.

How do you keep the site clean during the work?

By covering it before any work starts. We keep the work contained and clean down when we finish.

What types of premises do you cover?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

Can you price the work without visiting?

Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. Some sites still need a visit, and we’ll say so.

Do you need to switch the unit off?

Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.

Can you set up regular visits?

Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.

What we do, step by step

We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Cores End, let us know and we will plan around it.

  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. We finish with the fan section and the drain tray.
  5. We take after photos and issue the certificate and report.

Before we arrive

  • Let us know when the site is closed or quiet
  • Clear loose items from the work area
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice

Signs you need AHU cleaning in Cores End

Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.

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

  • Units needing a clean before a new tenant or handover
  • Dust built up on fan impellers
  • Rooms that smell stuffy when the system runs
  • Units that have only ever had filter changes

Healthcare ventilation, from large hospitals like Marlow Community Hospital (about 3 miles west) to small clinics, depends on clean filters, coils and ducts.

What to look for in a quote

  • Which accreditations they hold, and whether you can check them
  • Proof of insurance
  • What happens if part of the system can’t be accessed
  • What’s included in the scope, part by part

Questions to ask before you book

Managing agents and facilities teams in Cores End

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.

Going by the FSA’s register, there are about 7 schools, colleges and universities, about 8 hospitals, care homes and childcare premises and about 3 hotels and guest houses serving food within 1.5 miles or so of the middle of Cores End. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. The nearest hospital to Cores End is Marlow Community Hospital, about 3 miles west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.

Why deal with it now?

Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. With notice, the visit to Cores End can be fitted around your bookings and events.

Staff cleaning versus specialist work

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’s our job.

Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
