Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Make sure condensate is draining away
- File each AHU report in the maintenance log
- Keep filter changes on time and recorded
- Watch for drips or damp patches near the plant
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.
AHU cleaning in Marks Tey
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. Common call-outs are for blocked condensate drains and slimy trays and air handling units due a clean after building work, across internal panels, dampers and louvres and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Dirty ducts beyond the unit itself
- Problems with the unit’s controls or sensors
- Ventilation that was badly designed in the first place
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly.
Where we work
- Internal panels
- Supply and extract fans
- Heating and cooling coils
- Dampers and louvres
- Drain trays
- Filter sections
In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Your questions about AHU cleaning in Marks Tey
Can you do AHU cleaning in Marks Tey?
Yes, Marks Tey is covered. Get in touch with the details and we will arrange a survey.
Do you work overnight in Marks Tey?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Marks Tey needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Can you quote from photos?
Typically, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
Is there a survey before the work?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.

How the visit works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. For a village or hamlet like Marks Tey, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Clear loose items from the work area
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
How to get a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

When to call us in Marks Tey
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
What we are most often called out for:
- Air handling units with blocked filters
- Dust built up on fan impellers
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
If you run a surgery, dental practice or care home near Marks Tey, clean ventilation matters as much to you as to a hospital like Essex County Hospital (about 5.3 miles east).
What to look for in a quote
- How areas they cannot reach will be recorded
- Whether the price is fixed
- Whether the whole system is included, or only the parts that are easy to reach
- When the next visit should be, and why
Fixed quotes for AHU cleaning in Marks Tey
We quote each job individually. This is what makes a difference:
- Site requirements such as sign-in and permits
- Parking and loading at the site
- How many systems or sites are involved
- The scale of the work
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- Wide pictures of the system and the area around it
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.
