AHU cleaning in Horsemere Green

Do you need AHU cleaning in Horsemere Green?

Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.

Signs it’s time to call us include:

  • Dirty filters cutting the airflow
  • Fan sections that haven’t been cleaned in years
  • Odours coming through the supply air
  • Units that have only ever had filter changes

School buildings such as St Mary's CofE Primary School are usually done in the holidays, so classrooms are not disturbed.

Before you book anyone

  • Whether a survey comes first
  • If the quote is a fixed price or an estimate
  • Exactly which parts of the system are covered
  • Whether they recommend a next date

Our hiring checklist

AHU cleaning for kitchens and businesses in Horsemere Green

A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with stale or musty smells from the ventilation and debris and leaves in the fresh air intake, across filter sections, supply and extract fans and heating and cooling coils.

Work in a small place like Horsemere Green starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.

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. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Horsemere Green: your questions answered

Can you work in Horsemere Green outside opening hours?

Yes, evening, overnight and weekend work is normal for us. The work in Horsemere Green can fit around your hours. Tell us your opening hours when you ask for a quote.

Do you clean school ventilation in Horsemere Green in the holidays?

Yes. The holidays are the usual time for school work. With about 6 schools and colleges on the FSA’s register within roughly a mile and a half of Horsemere Green, it pays to plan holiday dates ahead. You can give us a ring on 0345 646 2711 or use the quote form with the dates the site is empty.

Can you look after several sites?

Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.

How far ahead should we book?

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

What is TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.

Can you quote from photos?

Yes, for many jobs. Send a few wide photos plus close-ups of panels, filters or grilles, and a fixed quote normally follows within one working day. If pictures aren’t enough, we’ll survey first.

What should I send you?

A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.

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.

The process

When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Horsemere Green run smoothly.

  1. We agree a shutdown window that suits the building.
  2. We take before pictures of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. We finish with the fan section and the drain tray.
  5. After photos are taken and the certificate issued.

Before we arrive

  • Clear loose items from the work area
  • Plan for cooking equipment or plant to be off before we arrive
  • Dig out any earlier paperwork for the system

Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before we start.

In-house cleaning or a specialist?

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.

Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.

For landlords and multi-site operators

Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.

We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.

When something else is needed

It’s worth knowing the limits before booking:

  • Faulty motors, drives or bearings
  • A system that’s undersized for the building
  • Controls and BMS settings that run the unit

If you’re not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.

Where we work

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

Why act early in Horsemere Green

Stuffy rooms and stale smells in a building in Horsemere Green 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: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

Why us?

  • One contact for all your sites in London and the South East
  • We diagnose before we treat
  • Fully insured
  • Fixed quotes, typically within one working day

Read our cost guide and our accreditations.

Between visits

Results last longer with the right care. We suggest:

  • Plan the next inspection before the last report gets filed away
  • Make sure condensate is draining away
  • Report stiff or damaged access doors
  • File each AHU report in the maintenance log

Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.

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