Book AHU cleaning in Hatton

What happens on the day

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes anything from half a day for one small unit to several shifts for a plant room full of them. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Hatton.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  4. We clean the coils and clear the tray and drain.
  5. The unit is closed up and handed back, with a report to follow.

Getting ready for the visit

  • Make sure equipment near the work can be switched off and left to cool
  • Mention any parking or loading restrictions
  • Tell us the best time to work, such as after service or at a weekend

How we handle AHU cleaning in Hatton

Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. Typical jobs include units that have only ever had filter changes and dust-coated heating and cooling coils, across dampers and louvres, drain trays and filter sections.

Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. In Hatton, as elsewhere, cleaning starts with an inspection of what’s there.

Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Different parts, different methods

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.

Internal casing and panels

Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.

For landlords and multi-site operators

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 on a regular cycle.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

Honest limits

Before booking, it helps to know what’s not included:

  • Ventilation that was badly designed in the first place
  • Coils that are corroded or leaking and need replacing
  • Controls and BMS settings that run the unit

If in doubt, ring 0345 646 2711 or use the quote form and we will say what we think before booking.

Hatton questions

Do you work at weekends in Hatton?

Yes, nights and weekends are routine for us. That way a site in Hatton does not have to lose a day’s trading. Let us know the hours you are closed and we will book within them.

Do you clean school ventilation in Hatton in the holidays?

Yes, out-of-term visits are normal for schools. Around Hatton, the Food Standards Agency lists about 13 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711, or send details by email with your term dates and we will plan around them.

How much notice do you need?

Earlier is better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.

Can you quote from photos?

Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.

What happens to the waste?

We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.

Do you need to switch the unit off?

Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.

Do you give a certificate after the clean?

Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.

What information do you need?

Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711 or drop us a line.

Do you need AHU cleaning in Hatton?

Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.

Most sites get in touch after spotting one of these:

  • Debris and leaves in the fresh air intake
  • Air handling units due a clean after building work
  • Drain trays holding standing water
  • Coils clogged with dust and debris

For schools like Cranford Primary School, the holidays are the usual time to inspect and clean ventilation.

Questions to ask before you book

  • Proof of accreditation you can verify
  • What records you’ll receive afterwards
  • When they can work, and whether that’s outside your opening hours
  • What’s included in the scope, part by part

Ventilation in Hatton buildings

Food Standards Agency data includes about 13 schools, colleges and universities, about 16 hospitals, care homes and childcare premises and about 19 hotels and guest houses in and around Hatton, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Hatton’s nearest hospital, Harlington, is about 1.9 miles north-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours.

Healthcare ventilation, from large hospitals like Harlington (about 1.9 miles north-west) to small clinics, depends on clean filters, coils and ducts.

Keeping the system healthy

Once we’ve finished, these simple steps help:

  • Store the TR19 paperwork where auditors can find it
  • Make sure the unit’s access doors open easily
  • Flag stale or damp smells in the supply air
  • Note any water around the unit or leaks below it

Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.

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

How we price AHU cleaning

Sites vary more than people expect. What affects the quote:

  • Whether we need access equipment or extra panels
  • How big the system is
  • Whether it’s a one-off visit or part of a schedule
  • Site rules, permits and inductions

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, ring 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

What to send for a quote:

  • The times we could work without disrupting the site
  • The postcode and the type of business
  • Detail shots of panels, filters and grilles
  • The paperwork from the last visit, if you have it

Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
