How the job changes from site to site

About our AHU cleaning in New Eltham
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. We’re often asked to deal with leaves and litter drawn into the unit and coils clogged with dust and debris, across drain trays, filter sections and internal panels.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in New Eltham is typically planned out of hours. Parking and loading are agreed with the building in advance.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What we’re called out for in New Eltham
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
These are the problems we see most often:
- Air handling units due a clean after building work
- Dust built up on fan impellers
- Intake sections clogged with outdoor debris
- Condensate trays that will not empty
Healthcare ventilation, from large hospitals like Eltham Community Hospital (about 1.1 miles north-west) to small clinics, depends on clean filters, coils and ducts.

Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you look at the system first?
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.

Multi-site and managed buildings

For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
How it works
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and we clear up before we go. For a job in New Eltham, tell us about loading bays, permits, lifts and roof access when you book.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Move anything stored near the system
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet

Between visits
Simple habits between visits make a real difference. Our advice:
- Flag stale or damp smells in the supply air
- Keep inspection doors on the unit in good order
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What affects the quote in New Eltham
Before we fix a price, we need to know a few things. We look at:
- How many systems or sites are involved
- Where the site is and how we reach it
- When the work can happen, such as evenings, overnight or weekends
- A single visit or a regular plan
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before any work starts.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Wide pictures of the system and the area around it
- Problems your staff have spotted
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
Some systems can be priced from pictures; others need a survey. 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.
