AHU cleaning for sites in Addlestone

What a clean won’t put right

Not every problem is solved by AHU cleaning, and we’ll tell you before any work starts. It doesn’t solve:

  • Coils that are corroded or leaking and need replacing
  • A system that is undersized for the building
  • Breakdowns that need a mechanical engineer

Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we will tell you honestly before booking.

What the work covers

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

How we handle AHU cleaning in Addlestone

Our AHU cleans for sites in Addlestone cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. The work covers supply and extract fans, internal panels and heating and cooling coils, and common reasons people get in touch are air handling units never cleaned inside and intake sections clogged with outdoor debris.

In a smaller place like Addlestone, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Smaller systems still gather dust and need inspecting.

The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Landlords, agents and facilities managers

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

Leave it or put it right?

If people in a building in Addlestone complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. You choose the date of a planned visit, and a breakdown never asks.

You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711 or send us an email, and we will talk you through it.

In-house cleaning or a specialist?

Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.

In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

What happens on the day

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 one overnight shift for many single units, with bigger plant phased. In a place like Addlestone, we fit the visit around your hours.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. We take before photos of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. The fan and drain tray are cleaned and the drain checked.
  5. We take after photos and issue the certificate and report.

Before we arrive

  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Tell us the best time to work, such as after service or at a weekend
  • Allow time for equipment near the work to be turned off and cool down

Can you price the work without visiting?

Aftercare tips

Think of this as the after-treatment advice, short and simple:

  • Keep inspection doors on the unit in good order
  • Keep filter changes on time and recorded
  • Check the drain tray is emptying during routine visits
  • Plan the next inspection before the last report gets filed away

If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.

Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
