About our AHU cleaning in Quendon
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. Common call-outs are for coils clogged with dust and debris and dust built up on fan impellers, across dampers and louvres, supply and extract fans and filter sections.
In a village or hamlet like Quendon, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Planning a trip to Quendon ahead is easier for everyone than a rushed one.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before any work starts.

What AHU cleaning cannot fix
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer before booking.
What the work covers
- Supply and extract fans
- Internal panels
- Heating and cooling coils
- Dampers and louvres
- Filter sections
- Drain trays
AHU cleaning in Quendon: local notes

What happens on the day

Advice
What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We check:
- How easy every part is to reach
- One-off work versus a regular cycle
- The condition we find in the survey
- Working hours and out-of-hours timing
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any previous report or certificate
- The times we could work without disrupting the site
- A few general shots of the system
- Where the site is and what kind of site it is
For a fixed quote, call 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You’ll normally have a quote within one working day.
How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.

In-house cleaning or a specialist?
Staff cleaning and specialist work aren’t the same thing. 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.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
