AHU cleaning in Hardwick

Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include leaves and litter drawn into the unit and plant that needs cleaning after a refit, on heating and cooling coils, supply and extract fans and dampers and louvres.

Work in a small place like Hardwick starts with agreeing access and timings.

We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What we do, step by step

We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from half a day for one small unit to several shifts for a plant room full of them. Visits to a village like Hardwick are booked in advance, at a time that suits whoever runs the site.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  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.

How to prepare

  • Mention any sign-in, permit or induction we need

How often should an air handling unit be cleaned?

Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.

When something else is needed

A few issues sit outside what this work can do:

  • Damaged coils beyond cleaning
  • Controls and BMS settings that run the unit

Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly before you book.

Signs you need AHU cleaning in Hardwick

Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.

Signs it’s time to call us include:

  • Intake sections clogged with outdoor debris
  • Plant that needs cleaning after a refit
  • Odours coming through the supply air
  • Filters that are clogged or overdue

Around Hardwick, as anywhere, ventilation cleaning begins with an inspection.

Before booking anyone

  • Whether the price is fixed
  • What insurance they carry
  • When the next visit should be, and why
  • What records you will receive afterwards

How to choose an extract cleaning contractor

What the work involves, part by part

Heating and cooling coils

Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.

Rooftop and plant room units

Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.

Landlords, agents and facilities managers

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

Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.

Between visits

Results last longer with the right care. Here’s what we suggest:

  • Keep filter changes on time and recorded
  • Make sure the unit’s access doors open easily
  • Do not ignore odours coming through the grilles
  • Book the next check in line with the report

Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.

Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
