What staff can safely do

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

How we handle AHU cleaning in Milton-under-Wychwood

Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. If you have debris and leaves in the fresh air intake and units that have only ever had filter changes, we can help, from internal panels, supply and extract fans and drain trays onwards.

For a building in or near Milton-under-Wychwood, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.

Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Common problems we fix in Milton-under-Wychwood

Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.

Keep an eye out for these warning signs:

  • Fan sections that haven’t been cleaned in years
  • Coils clogged with dust and debris
  • Units that have only ever had filter changes
  • Filters that are clogged or overdue

School buildings such as Wychwood Church of England Primary School are typically done in the holidays, so classrooms aren’t disturbed.

Questions to ask before booking

  • Whether the quote is based on a survey or pictures
  • How areas they cannot reach will be recorded
  • Proof of accreditation you can verify
  • What’s included in the scope, part by part

Our hiring checklist

Multi-site and managed buildings

We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Work can be phased by floor, building or site around the people who use them.

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.

Different parts, different methods

Internal casing and panels

Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.

Heating and cooling coils

Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.

Why it’s worth doing now in Milton-under-Wychwood

Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Somewhere as small as Milton-under-Wychwood, losing a kitchen or building to a fault is felt by everyone who uses it.

Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

What you get with us

  • A fixed price before any work starts
  • One number for every site across the South East and London
  • Photo reports with every job
  • Out-of-hours work and a 24/7 emergency line

Looking after it afterwards

How long the results last depends on use and care. We suggest:

  • File each AHU report in the maintenance log
  • Keep filter changes on time and recorded
  • Clear leaves and litter away from the intake
  • Keep inspection doors on the unit in good order

If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.

Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

How it works

We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Milton-under-Wychwood before we set off.

  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. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After pictures are taken and the certificate issued.

Before we arrive

  • Make sure someone can let us in and lock up afterwards
  • Mention any sign-in, permit or induction we need
  • Find the previous report, if there is one

Ask for a quote

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 pictures, get a survey first. Either way, you get a fixed price before any work starts.
