AHU cleaning for sites in Penshurst

What staff can safely do

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

AHU cleaning in Penshurst, done properly

A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. If you have plant that needs cleaning after a refit and fan sections that haven’t been cleaned in years, we can help, from drain trays, internal panels and supply and extract fans onwards.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.

Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

For Penshurst, the closest hospital is Tonbridge Cottage Hospital, roughly 4.2 miles east. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

Wherever a school like Penshurst Church of England Voluntary Aided Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare ventilation, from large hospitals like Tonbridge Cottage Hospital (about 4.2 miles east) to small clinics, depends on clean filters, coils and ducts.

Why deal with it now?

Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. In a place like Penshurst, ductwork and fans are easy to forget until something goes wrong.

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or send us an email for straight advice and a fixed quote.

Read what affects the cost and how to check a contractor.

Multi-site and managed buildings

We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Honest limits

AHU cleaning can’t fix everything, and we will tell you before we start. It won’t put right:

  • Dirty ducts beyond the unit itself
  • Building management system faults
  • Mechanical faults with motors, belts or bearings

If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think.

Parts of the system we cover

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

What affects the quote in Penshurst

A fixed price needs a few facts first. We check:

  • One-off work versus a regular cycle
  • How easy every part is to reach
  • Parking and loading at the site
  • The number of sites or systems

When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before we start.

What we need to know

Photos let us diagnose from a distance. Try to include:

  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Your last certificate, test record or report
  • When the site is open and when it’s quiet
  • A few general shots of the system

To get a fixed quote, call us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

Penshurst questions

Do you work at weekends in Penshurst?

Yes, nights and weekends are routine for us. That way a site in Penshurst does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.

Can you do AHU cleaning in Penshurst?

Yes. We work across London and the South East, and Penshurst is part of that. You can call 0345 646 2711, or send details by email and let us know what needs doing.

Do you offer maintenance contracts?

Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.

Where does the waste go?

Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.

Is a quote from pictures possible?

In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.

What happens if you cannot reach some of it?

They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.

What accreditations do you have?

BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.

Can you fix a faulty AHU?

Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.

How the visit works

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. For a village or hamlet like Penshurst, tell us about narrow lanes, gates and parking when you book.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. The unit is shut down with your site team and the area protected.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Drain trays are cleared and cleaned and the outlet checked.
  5. A TR19® certificate and photo report follow the clean.

How to prepare

  • Clear loose items from the work area
  • Let us know about permits to work or site inductions
  • Name a contact who can let us in at the agreed time

Ask for a quote

The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

How the job changes from site to site

Drain trays

A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.

Internal casing and panels

Dust settles on every internal surface of the unit. We clean each section from intake to discharge.
