AHU cleaning in Catslip

We clean air handling units for buildings in Catslip and across Oxfordshire, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. Typical jobs include dirty coils holding back the airflow and dirty filters cutting the airflow, across filter sections, supply and extract fans and drain trays.

In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.

Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

How the visit works

We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Seeing the system in pictures first means the trip to Catslip can be planned properly.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters, coils, fan section and casing are cleaned in turn.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. We close up the unit and send the certificate and before and after photos.

Getting ready for the visit

  • Name a contact who can let us in at the agreed time
  • Clear the space around the work
  • Tell us about site rules, permits or sign-in

Common questions in Catslip

Can you do AHU cleaning in Catslip?

Yes, Catslip is within the area we cover across London and the South East. You can call us on 0345 646 2711 or use the quote form and let us know what needs doing.

Do you work at weekends in Catslip?

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

What should I send you?

Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then phone us on 0345 646 2711 or send us an email.

What do you clean inside the unit?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.

Do you repair air handling units?

Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.

What do you do to protect the area?

Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.

Can you look after several sites?

Yes. One number covers all your sites in our area, with visits on a regular schedule.

Can you quote from pictures?

Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.

Landlords, agents and facilities managers

When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.

Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.

Leave it or put it right?

A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Systems in rural buildings are often out of sight and out of mind.

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

What your team can do, and what needs us

Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

What AHU cleaning cannot fix

It’s worth knowing the limits before booking:

  • Building management system faults
  • Ductwork downstream of the unit, which is a separate clean
  • Mechanical faults with motors, belts or bearings

If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.

What the work covers

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

What affects the cost of AHU cleaning

Every site gets its own quote. These are the things that affect it:

  • How big the system is
  • The times the site is available
  • Whether we need access equipment or extra panels
  • The condition of the system

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Asking for a quote

There’s no need for technical detail. It helps if you can send:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • How we’d reach plant on a roof or in a plant room
  • Where the site is and what kind of site it is
  • Detail shots of panels, filters and grilles

There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or email photos.

Signs you need AHU cleaning in Catslip

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.

It’s time to book a visit if you see:

  • Fan sections that haven’t been cleaned in years
  • Condensate trays that won’t empty
  • Dirty coils holding back the airflow
  • Units that have only ever had filter changes

For buildings in and around Catslip, TR19® Air cleaning starts with an inspection.

Before booking anyone

  • Whether they recommend a next date
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • If the quote is a fixed price or an estimate
  • What insurance they carry
