AHU cleaning near Great Thorness

AHU cleaning for kitchens and businesses in Great Thorness

Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Typical jobs include dirty coils holding back the airflow and air handling units never cleaned inside, across drain trays, supply and extract fans and dampers and louvres.

Somewhere as small as Great Thorness, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

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

Looking after it afterwards

Good habits slow the build-up between visits. A few tips:

  • Keep filter changes on time and recorded
  • Store the TR19 paperwork where auditors can find it
  • Make sure the unit’s access doors open easily
  • Report water on the plant room floor

The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Change or clean filters on time. Once filters clog, dirt starts getting past them.

Why deal with it now?

Stuffy rooms and stale smells in a building in Great Thorness can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Out of sight is the usual reason a rural system goes too long without attention.

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

How the visit works

When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Great Thorness is set by you, and the travel is our side of the planning.

  1. We look at the unit and the plant area during the survey.
  2. The area is protected and the unit made safe.
  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.

How to prepare

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Make sure equipment near the work can be switched off and left to cool
  • Agree a time when the area can be out of use

Ask for a quote

Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

Advice

Honest limits

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

  • Faulty motors, drives or bearings
  • Airflow problems caused by the system’s design
  • Dirty ducts beyond the unit itself

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

What we work on in Great Thorness

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

What the work involves, part by part

Internal casing and panels

The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.

Filters

Clogged filters reduce airflow, and dirt can get round the edges. The filter section is cleaned so new or cleaned filters sit properly.

Fixed quotes for AHU cleaning in Great Thorness

A fixed price needs a few facts first. We look at:

  • One-off work versus a regular cycle
  • The size of the system
  • The condition of the system
  • When the work can happen, such as evenings, overnight or weekends

What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.

What we need to know

We can often survey from photos. The most useful are:

  • The roof, plant room or outside wall the system runs to
  • Wide pictures of the system and the area around it
  • Where the site is and what kind of site it is
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

FAQs for Great Thorness

Is AHU cleaning available in Great Thorness?

Yes. Our area runs across London and the South East, Great Thorness included. To start, give us a ring on 0345 646 2711 or email us with a few photos of the system.

Do you cover smaller places like Great Thorness?

Yes. Villages and rural sites across the South East are part of our work, Great Thorness included. A survey first, from photos or a visit, means we arrive with the right kit.

What happens if you cannot reach some of it?

They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.

How often do AHUs need cleaning?

It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.

How long will the unit be out of action?

The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, and you can phone us on 0345 646 2711, or email photos to plan it.

How far ahead should we book?

That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.

How much does AHU cleaning cost?

We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.

Can you look after several sites?

Yes. Send the list of sites and the work at each and you’ll get one fixed quote.

For landlords and multi-site operators

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

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
