How we handle AHU cleaning in Ifieldwood
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. If you have plant that needs cleaning after a refit and dust-coated heating and cooling coils, we can help.
Somewhere as small as Ifieldwood, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
When something else is needed
AHU cleaning can’t fix everything, and we’d rather say so up front. It will not put right:
- Faulty motors, drives or bearings
- Building management system faults
- The supply and extract ducts, quoted separately
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly before you book.
Parts of the system we cover
- Supply and extract fans
- Drain trays
- Internal panels
- Dampers and louvres
- Heating and cooling coils
- Filter sections
Between visits
Here’s the after-treatment advice, short and simple:
- Watch for drips or damp patches near the plant
- Report stiff or damaged access doors
- Diary the inspection date recommended in the report
- Keep filter changes on time and recorded
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to Ifieldwood run smoothly.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive

Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

Why act early in Ifieldwood
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. It’s simpler to plan the work at Ifieldwood now than to arrange it in a hurry later.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- The condition of the system
- Access, including roofs, risers and ceiling voids
- Working hours and out-of-hours timing
- Where the site is and how we reach it
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- Wide pictures of the system and the area around it
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, ring 0345 646 2711, or send details by email.

FAQs for Ifieldwood
Is Ifieldwood within the area you cover?
Yes. Ifieldwood is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Can you clean school ventilation in Ifieldwood during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 4 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ifieldwood. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What do you need from me for a quote?
Some pictures and a quick description of the system plus the address and your hours. If we need more, we’ll ask.
What happens if you can’t reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with photos where it helps.
