Can a school’s ventilation in Daws Heath be done out of term time?

Yes, out-of-term visits are normal for schools. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Daws Heath. Tell us your holiday dates and we will book the visit for when the site is empty.

How do you protect the area?

By covering it before any work starts. The work is kept contained and leave the area clean.

What types of premises do you cover?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.

How long does it take to clean an air handling unit?

As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, including evenings or weekends.

Which parts of an air handling unit do you clean?

We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.

Are you insured?

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

What is TR19?

A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.

How we handle AHU cleaning in Daws Heath

Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote before any cleaning starts. We are often asked to deal with rooms that smell stuffy when the system runs and fan sections that haven’t been cleaned in years, across internal panels, filter sections and heating and cooling coils.

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

The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

How it works

Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere like Daws Heath, lanes, gates and parking are worth mentioning in advance.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. We take before pictures of each section of the unit.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. We finish with the fan section and the drain tray.
  5. We take after photos and issue the certificate and report.

Getting ready for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Mention any sign-in, permit or induction we need
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Landlords, agents and facilities managers

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 records stay tidy.

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

Between visits

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

  • Book the next check in line with the report
  • Change filters on schedule and log each change
  • Store the TR19 paperwork where auditors can find it
  • Report musty smells from the vents straight away

Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.

Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.

When it’s something else

To be straight with you, some problems need a different fix:

  • Faulty motors, drives or bearings
  • Leaking heating or cooling coils
  • Problems with the unit’s controls or sensors

Not sure which it is? You can call us on 0345 646 2711, or email photos and we will tell you honestly.

What we work on in Daws Heath

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

Staff cleaning versus specialist work

Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.

What the work involves, part by part

Fans and fan sections

Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.

Heating and cooling coils

Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.

Common problems we fix in Daws Heath

An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.

These are the problems we see most often:

  • Drain trays holding standing water
  • Units needing a clean before a new tenant or handover
  • Dust-coated heating and cooling coils
  • Stale or musty smells from the ventilation

School buildings such as The Deanes School are typically done in the holidays, so classrooms are not disturbed.
