AHU cleaning across Nashes Green

What AHU cleaning can’t fix

In fairness, some problems need a different fix:

  • Breakdowns that need a mechanical engineer
  • Airflow problems caused by the system’s design
  • Ductwork downstream of the unit, which is a separate clean

What we work on in Nashes Green

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

AHU cleaning in Nashes Green, done properly

An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. Common call-outs are for drain trays holding standing water and units that have only ever had filter changes, on supply and extract fans, heating and cooling coils and internal panels.

Somewhere as small as Nashes Green, ducted ventilation is normally 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.

Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Keeping the system healthy

To keep the system working properly between visits:

  • Report musty smells from the vents straight away
  • 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. A clean unit feeding dirty ducts only solves half the problem, 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.

Staff cleaning versus specialist work

Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

Why deal with it now?

Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. In a place like Nashes Green, ductwork and fans are easy to forget until something goes wrong.

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 work begins.

What you get with us

  • A single point of contact for sites across the South East and London
  • We diagnose before we treat
  • CHAS and SafeContractor accredited, with ISO 9001

Landlords, agents and facilities managers

Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together 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 can quote either party and send the paperwork to whoever needs it.

Nashes Green: your questions answered

Can the work in Nashes Green be done at night or at weekends?

Will you come out to Nashes Green?

Yes. Villages and rural sites across the South East are part of our work, Nashes Green included. Photos of the system and directions to the site help us plan the visit.

When should our AHU next be cleaned?

Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.

What’s included in an AHU clean?

All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.

Can you clean the ducts connected to the AHU?

Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.

Do you survey before quoting?

Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.

What if parts of the system cannot be reached?

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

How much does AHU cleaning cost in Nashes Green?

The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will typically reply within one working day.

What happens on the day

At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes from a few hours for a compact unit to a day or more for a large one. Pictures of the system and its access let us plan the work in Nashes Green before we set off.
