About our AHU cleaning in Almshouse Green
We clean air handling units for buildings in Almshouse Green and across Essex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include filters that are clogged or overdue and plant that has been serviced but not cleaned, on drain trays, internal panels and supply and extract fans.
Work in a small place like Almshouse Green starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any permits to work or inductions
- Where the site is and how we reach it
- The condition we find in the survey
- Working hours and out-of-hours timing
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before we start.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- Your opening hours and when the area is out of use
Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Store the TR19 paperwork where auditors can find it
- Keep filter changes on time and recorded
- Report water on the plant room floor
- Keep the area around the fresh air intake clear
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

Advice
When to call us in Almshouse Green
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Keep an eye out for these warning signs:
- Intake sections clogged with outdoor debris
- Condensate trays that will not empty
- Air handling units with blocked filters
- Units that have only ever had filter changes
Wherever a school like Hedingham School and Sixth Form has ducted ventilation, a half-term visit keeps the work out of lesson time.
What to look for in a quote
- Whether they’re fully insured
- Whether the figure could change on the day
- How VAT is shown on the quote
- Whether inaccessible sections are listed on the report
Your questions about AHU cleaning in Almshouse Green
Do you work overnight in Almshouse Green?
Yes, out-of-hours work is a big part of what we do. The work in Almshouse Green can fit around your hours. Let us know the hours you are closed and we will book within them.
Can you get to a site in Almshouse Green?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
How far ahead should we book?
The more notice, the better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
What do you do to protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with photos where it helps.
What information do you need?
Some photos and a quick description of the system plus the address and your hours. We’ll ask for anything else we need.
Will the ventilation be off while you clean?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- Building management system faults
- Ductwork downstream of the unit, which is a separate clean
- Airflow problems caused by the system’s design
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.
What the work covers
- Dampers and louvres
- Internal panels
- Filter sections
- Drain trays
- Supply and extract fans
- Heating and cooling coils
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
