AHU cleaning for sites in Braiswick

How it works

Every visit runs to the same pattern: protect the area, make the system safe, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Braiswick, the date and timings are agreed with you well before the day.

  1. We agree a shutdown window that suits the building.
  2. We take before photos of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After photos are taken and the certificate issued.

Preparing for the visit

  • Dig out any earlier paperwork for the system
  • Tell us about site rules, permits or sign-in
  • Agree a time when the area can be out of use

How to get a quote

For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We typically come back within one working day.

Advice

About our AHU cleaning in Braiswick

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. The work covers filter sections, internal panels and drain trays, and common reasons people get in touch are filters that are clogged or overdue and dust built up on fan impellers.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.

Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How the job changes from site to site

Filters

Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.

Rooftop and plant room units

Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.

When something else is needed

To be straight with you, there are a few things this work won’t fix:

  • A system that is undersized for the building
  • Ductwork downstream of the unit, which is a separate clean
  • Controls and BMS settings that run the unit

Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.

Parts of the system we cover

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

What we’re called out for in Braiswick

Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Braiswick, that is air they breathe for hours at a time.

What we’re most often called out for:

  • Dust built up on fan impellers
  • Air handling units due a clean after building work
  • Leaves and litter drawn into the unit
  • Dirty filters cutting the airflow

Hospitals such as Essex County Hospital (about 0.8 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Braiswick are no different.

Questions to ask before booking

Why it’s worth doing now in Braiswick

A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Equipment tucked in a roof space or outbuilding near Braiswick rarely gets looked at unless someone books it.

Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Your questions about AHU cleaning in Braiswick

Do you work overnight in Braiswick?

Yes, we can come after you close and finish before you open. It means the site in Braiswick keeps running as normal. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.

Will you come out to Braiswick?

Yes, we work in villages as well as towns, and Braiswick is covered. Photos of the system and directions to the site help us plan the visit.

What do you do with what you remove?

It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.

Can you look after several sites?

Yes. Our area covers London and the South East, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.

How often do AHUs need cleaning?

TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.

How do you keep the site clean during the work?

Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.

How much does AHU cleaning cost?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.

Do you have insurance?

Yes. We’re fully insured, and we can share the details when you need them.

Between visits

Simple habits between visits make a real difference. Our advice:

  • Make sure the unit’s access doors open easily
  • Clear leaves and litter away from the intake
  • Check the drain tray is emptying during routine visits
  • Flag stale or damp smells in the supply air

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

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

Multi-site and managed buildings

When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
