AHU cleaning across Eynsham

About our AHU cleaning in Eynsham

If the units serving a building in Eynsham have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Typical jobs include plant that has been serviced but not cleaned and filters that are clogged or overdue, across internal panels, drain trays and supply and extract fans.

In a place like Eynsham, air handling units are often tucked into roof spaces or small plant rooms, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

There are about 4 schools, colleges and universities and about 5 care, childcare and hospital premises on the FSA’s food hygiene register across Eynsham and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Eynsham’s nearest hospital, Radcliffe Infirmary, is about 5.1 miles east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. Eynsham, about 58 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.

FAQs for Eynsham

Do you work at weekends in Eynsham?

Yes, nights and weekends are routine for us. The work in Eynsham can fit around your hours. Let us know the hours you’re closed and we’ll book within them.

Can you get to a site in Eynsham?

Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

What if parts of the system cannot be reached?

Anything we cannot reach goes on the report, with pictures where possible, and we tell you what would make it reachable, such as extra access panels in ductwork.

What do you do to protect the area?

We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

Is there a report after cleaning?

Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.

What is TR19?

TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Is a quote from pictures possible?

Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If photos are not enough, we will survey first.

How often do AHUs need cleaning?

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

Leave it or put it right?

If people in a building in Eynsham complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Booking ahead lets us plan the trip to Eynsham at a time that suits you.

Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Keeping the system healthy

Simple habits between visits make a real difference. We recommend:

  • Do not store bins or materials near the intake
  • Change filters on schedule and log each change
  • Keep the certificate and photo report with the plant records
  • Watch for drips or damp patches near the plant

Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.

Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

When it’s something else

An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:

  • Problems with the unit’s controls or sensors
  • Airflow problems caused by the system’s design
  • Damaged coils beyond cleaning

Not sure which it is? You can give us a ring on 0345 646 2711, or send details by email and we’ll tell you honestly before you book.

What we work on in Eynsham

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

How the visit works

We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We plan the journey to Eynsham and bring what the job is likely to need.

  1. First the unit is surveyed, from photos 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, coils, fan section and casing are cleaned in turn.
  4. We clean out the drain tray and make sure it drains.
  5. We close up the unit and send the certificate and before and after pictures.

Before we arrive

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Let us know when the site is closed or quiet
  • Find the previous report, if there is one

Getting a quote

For a fixed quote, give us a ring on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll usually have a quote within one working day.

Related advice

What your team can do, and what needs us

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Managing agents and facilities teams in Eynsham

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.

How the job changes from site to site

Internal casing and panels

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

Heating and cooling coils

Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
