AHU cleaning in North Aston

Our AHU cleaning covers sites in North Aston and the rest of Oxfordshire, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have dirty coils holding back the airflow and dirty fans and fan housings, we can help, from internal panels, heating and cooling coils and dampers and louvres onwards.

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

For insurers and inspectors, the record counts. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What the work involves, part by part

Rooftop and plant room units

Units outside are exposed to weather and windblown debris. The intake section gets particular attention.

Drain trays

A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.

In-house cleaning or a specialist?

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Between visits

After the visit, a few habits help the work last:

  • Look at the condensate drain whenever the unit is serviced
  • Clear leaves and litter away from the intake
  • Diary the inspection date recommended in the report
  • Report stiff or damaged access doors

The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Keep the area around the intake clear. Anything around the intake is likely to be drawn in.

Why deal with it now?

Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. It’s worth booking a check, because nobody sees inside a duct day to day.

Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.

What you get with us

  • We diagnose before we treat
  • Photo reports with every job
  • A fixed price before any work starts
  • Evenings, overnight and weekends, plus 24/7 emergency callout

How it works

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 half a day to a full day per unit, with large plant planned over several shifts. The timing of a visit to North Aston is set by you, and the travel is our side of the planning.

  1. First the unit is surveyed, from pictures or a visit, and the scope agreed.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  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. We close up the unit and send the certificate and before and after photos.

Before we arrive

  • Arrange a key holder or contact on site
  • Make sure equipment near the work can be switched off and left to cool
  • Mention any locked doors, roof access or ceiling voids

Getting a quote

We don’t publish a price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.

Signs you need AHU cleaning in North Aston

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 North Aston, that is air they breathe for hours at a time.

These are the problems we see most often:

  • Condensate trays that will not empty
  • Plant that has been serviced but not cleaned
  • Dirty coils holding back the airflow
  • Filters that are clogged or overdue

For sites in and around North Aston, the units and the ductwork are both looked at.

Questions to ask before booking

  • Exactly which parts of the system are covered
  • Whether they recommend a next date
  • What paperwork you get at the end
  • Whether the quote is based on a survey or pictures

How to choose an extract cleaning contractor

For landlords and multi-site operators

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.

We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Work can be phased by floor, building or site around the people who use them.
