AHU cleaning in Cudham, done properly

We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers supply and extract fans, heating and cooling coils and filter sections, and the jobs we see most are dirty coils holding back the airflow and dirty filters cutting the airflow.

Somewhere as small as Cudham, ducted ventilation is normally 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.

For insurers and inspectors, the record counts. That’s 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.

What happens if it’s left?

When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. It’s simpler to plan the work at Cudham now than to arrange it in a hurry later.

You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

Different parts, different methods

Internal casing and panels

Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.

Drain trays

The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.

Common questions in Cudham

Can the work in Cudham be done at night or at weekends?

Yes, out-of-hours work is a big part of what we do. It means the site in Cudham keeps running as normal. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.

Can you get to a site in Cudham?

Yes, Cudham is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.

Do you offer maintenance contracts?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.

Does the AHU have to be shut down for cleaning?

Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.

How long does an AHU clean take?

Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, so ring 0345 646 2711, or email photos to talk it through.

How often should an air handling unit be cleaned?

It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.

Can one contract cover all our sites?

Yes. One number covers all your sites in our area, with visits on a regular schedule.

What do you need from me for a quote?

Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.

Signs you need AHU cleaning in Cudham

Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.

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

  • Filters that are clogged or overdue
  • Rooms that smell stuffy when the system runs
  • Drain trays holding standing water
  • Units needing a clean before a new tenant or handover

Orpington Hospital, about 3.3 miles north, is the nearest hospital to Cudham, and healthcare sites of every size need their supply air kept clean.

What to look for in a quote

  • When they can work, and whether that is outside your opening hours
  • Whether the price is fixed
  • How they set the interval to the next visit
  • Whether a survey comes first

Choosing a duct cleaning contractor

The process

At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes from a few hours for a compact unit to a day or more for a large one. Somewhere as small as Cudham, the date and timings are agreed with you well before the day.

  1. We survey the unit from pictures or on site and agree what’s included.
  2. We arrange the shutdown with your staff and sheet the area.
  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 pictures.

How to prepare

  • Tell us where we can park and unload
  • Let us know when the site is closed or quiet
  • Plan for cooking equipment or plant to be off before we arrive

What your team can do, and what needs us

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Cudham buildings and their air

Food Standards Agency records list about 4 hospitals, care homes and childcare premises registered as food businesses within about 1.5 miles of central Cudham. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 3.3 miles north of Cudham is Orpington Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Cudham, about 15 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.

Wherever a school like Cudham Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Honest limits

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

  • Faulty motors, drives or bearings
  • Controls and BMS settings that run the unit
  • Dirty ducts beyond the unit itself
