About our AHU cleaning in Bridge Green
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers dampers and louvres, heating and cooling coils and drain trays, and people most often call us about dust built up on fan impellers and blocked condensate drains and slimy trays.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
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.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Book the next check in line with the report
- Report stiff or damaged access doors
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Change or clean filters on time. Once filters clog, dirt starts getting past them.

Your questions about AHU cleaning in Bridge Green
Do you cover smaller places like Bridge Green?
Yes, we work in villages as well as towns, and Bridge Green is covered. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Bridge Green after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Bridge Green needn’t be disturbed. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Do you have insurance?
Yes. Full insurance covers our work and have been trading since 2009.
Do you need AHU cleaning in Bridge Green?
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
These are the problems we see most often:
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
Around Bridge Green, as anywhere, ventilation cleaning begins with an inspection.
What your quote should include
- What insurance they carry
- Whether a survey comes first
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- If the quote is a fixed price or an estimate
What affects the cost of AHU cleaning
The survey tells us what the work involves. The main factors are:
- Parking and loading at the site
- Site requirements such as sign-in and permits
- How easy every part is to reach
- A single visit or a regular plan
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711, or email photos, and we will explain what it covers.
What we need to know
Before you ask for a quote, gather:
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Wide pictures of the system and the area around it
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What we do, step by step
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to Bridge Green.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Mention any parking or loading restrictions
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
Ask for a quote
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

For landlords and multi-site operators
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
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.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
