AHU cleaning in Dibden Purlieu

Why deal with it now?

Dirt left in an air handling unit doesn’t stay in the unit. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Systems on quieter sites still build up dirt and wear, just more slowly.

No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What you get with us

  • Fixed quotes from a survey or pictures
  • We are fully insured
  • Out-of-hours work and a 24/7 emergency line
  • Photo reports with every job

About our AHU cleaning in Dibden Purlieu

Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. If you have stale or musty smells from the ventilation and plant that has been serviced but not cleaned, we can put it right, from filter sections, heating and cooling coils and drain trays onwards.

Visits to a place like Dibden Purlieu are fitted around opening hours. The work is the same as in any town: inspect, clean, record.

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

Between visits

Simple habits between visits make a real difference. We recommend:

  • Report stiff or damaged access doors
  • Keep filter changes on time and recorded
  • File each AHU report in the maintenance log
  • Clear leaves and litter away from the intake

Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.

Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

Managing agents and facilities teams in Dibden Purlieu

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.

How the visit works

Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. The visit takes one overnight shift for many single units, with bigger plant phased. Because the survey comes first, a visit to Dibden Purlieu can usually be finished without a second trip.

  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. We close every panel, hand the unit back and send the report and certificate.

Getting ready for the visit

  • Allow time for equipment near the work to be turned off and cool down
  • Make sure someone can let us in and lock up afterwards
  • Tell us where we can park and unload

Ask for a quote

Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

Advice

What staff can safely do

Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.

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 can diagnose it and quote.

FAQs for Dibden Purlieu

Can you work in Dibden Purlieu outside opening hours?

Yes, nights and weekends are routine for us. Your customers, staff or residents in Dibden Purlieu needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.

Do you cover smaller places like Dibden Purlieu?

Yes. Villages and rural sites across the South East are part of our work, Dibden Purlieu included. The journey is planned ahead, so a few details about the route help.

How often should an air handling unit be cleaned?

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.

Does the AHU have to be shut down for cleaning?

Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.

Do you do ventilation duct cleaning too?

Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.

What do you clean inside the unit?

The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.

Is there a survey before the work?

Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

What about areas you cannot get to?

We record them on the report, with pictures where possible, and we explain what access is needed, for example new access panels.

Part by part

Heating and cooling coils

Dirt on a coil slows the air and makes it harder for the coil to heat or cool. Cleaning restores the open path through the fins.

Drain trays

A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.

What affects the quote in Dibden Purlieu

Some jobs are bigger than they look, and some smaller. The main factors:

  • Site rules, permits and inductions
  • How big the system is
  • Whether we need access equipment or extra panels
  • How many systems or sites are involved

What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before we start, so there are no surprises.

Helping us quote

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

  • Your last certificate, test record or report
  • The times we could work without disrupting the site
  • The site address and the type of premises
  • Where the plant sits or the system leaves the building, such as a roof or outside wall

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
