How we handle AHU cleaning in Wellhouse

Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. We are often asked to deal with air handling units with blocked filters and dust-coated heating and cooling coils, across dampers and louvres, internal panels and filter sections.

Somewhere as small as Wellhouse, 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.

The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What the work involves, part by part

Internal casing and panels

Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.

Rooftop and plant room units

Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.

Multi-site and managed buildings

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

How it works

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. A few photos of the system help us make the most of a visit to a place like Wellhouse.

  1. We survey the unit from photos or on site and agree what’s included.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. A TR19® certificate and photo report follow the clean.

Preparing for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Clear the space around the work
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

What AHU cleaning looks like in Wellhouse

Going by the FSA’s register, there are about 3 schools, colleges and universities serving food in Wellhouse and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Wellhouse’s nearest hospital, West Berkshire Community Hospital, is about 3.4 miles south-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. We cover Wellhouse, about 50 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.

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

Wellhouse is about 3 miles north of Thatcham, in West Berkshire. Wellhouse gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Our area takes in 155 places across West Berkshire, from busy centres to quieter spots. We also work in Reading, around 12 miles away.

Every address in RG18 is covered for AHU cleaning, from the main roads to the quietest streets. Close by, we work in Hermitage (1 mile west), Little Hungerford (1 mile north-west), Oare (1 mile north-west), Longlane (1 mile west) and Cold Ash (2 miles south). We also work in nearby towns such as Newbury (5 miles south-west), Thatcham (3 miles south), Burghfield Common (9 miles south-east), Speenhamland (4 miles south-west), Hungerford (12 miles west) and Spencers Wood (13 miles east).

What AHU cleaning can’t fix

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

  • Airflow problems caused by the system’s design
  • Damaged coils beyond cleaning
  • Controls and BMS settings that run the unit

If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think before booking.

What we work on in Wellhouse

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

What staff can safely do

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

Between visits

A little care between visits keeps the system in better shape. We recommend:

  • Watch for drips or damp patches near the plant
  • Do not ignore odours coming through the grilles
  • File each AHU report in the maintenance log
  • Report stiff or damaged access doors

Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.

Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.

Signs you need AHU cleaning in Wellhouse

Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.

Look out for these warning signs:

  • Units that have only ever had filter changes
  • Dirty fans and fan housings
  • Odours coming through the supply air
  • Dirty coils holding back the airflow

Hospitals such as West Berkshire Community Hospital (about 3.4 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Wellhouse are no different.

Wellhouse questions

Will you come out to Wellhouse?

Yes, we work in villages as well as towns, and Wellhouse is covered. A survey first, from pictures or a visit, means we arrive with the right kit.

Can you come to Wellhouse after we close?

Yes, we can come after you close and finish before you open. The work in Wellhouse can fit around your hours. Tell us your opening hours when you ask for a quote.

Do you repair air handling units?

Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.

What accreditations do you have?

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Can you quote from photos?

Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote normally follows within one working day. Some sites still need a visit, and we will say so.

What if parts of the system cannot be reached?

We record them on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.

Are you insured?

Yes. We carry full insurance, and we’ve been trading since 2009.

Do you clean the ductwork as well?

Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.
