How we handle AHU cleaning in Butt's Green
We clean air handling units for buildings in Butt's Green and across Essex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you have plant that has been serviced but not cleaned and condensate trays that won’t empty, we can put it right.
In a village or hamlet like Butt's Green, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Butt's Green buildings and their air
At about 31 miles from central London, Butt's Green sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site.

Hospitals such as Baddow Hospital (about 1.8 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Butt's Green are no different.

How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. The timing of a visit to Butt's Green is set by you, and the travel is our side of the planning.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use

Advice
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. Systems in rural buildings are often out of sight and out of mind.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Signs you need AHU cleaning in Butt's Green
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
Common reasons sites call us include:
- Filters that are clogged or overdue
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
- Blocked condensate drains and slimy trays
If you manage a school such as The Sandon School, ventilation cleaning is best booked for the holidays.
Before booking anyone
- Proof of insurance
- Proof of accreditation you can verify
- Whether the work can be done while the site is closed
- Whether a written report and photos are included
Different parts, different methods
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Drain trays
A tray that doesn’t drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Report stiff or damaged access doors
- Store the TR19 paperwork where auditors can find it
- Change filters on schedule and log each change
- Make sure condensate is draining away
We recommend when the unit should next be inspected or cleaned, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. What we look at:
- The number of sites or systems
- Site rules, permits and inductions
- The size of the system
- How easy every part is to reach
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.
Asking for a quote
To help us quote quickly, please include:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- When the site is open and when it’s quiet
- Problems your staff have spotted
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Questions from Butt's Green
Do you cover smaller places like Butt's Green?
Yes, we work in villages as well as towns, and Butt's Green is covered. Photos of the system and directions to the site help us plan the visit.
Do you work overnight in Butt's Green?
Yes, out-of-hours work is a big part of what we do. The work in Butt's Green can fit around your hours. Just call 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where needed.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
Are you insured?
Yes. Full insurance covers our work, and we have been trading since 2009.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
Does the AHU have to be shut down for cleaning?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
When something else is needed
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Ductwork downstream of the unit, which is a separate clean
- Controls and BMS settings that run the unit
- A system that is undersized for the building
If in doubt, ring 0345 646 2711 or send us an email and we will say what we think before booking.
Parts of the system we cover
- Supply and extract fans
- Heating and cooling coils
