Crockenhill AHU cleaning
AHU cleaning for Crockenhill, from a team that has been trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- Air handling units with blocked filters
- Units that have only ever had filter changes
- Plant that needs cleaning after a refit
How we handle AHU cleaning in Crockenhill
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. Typical jobs include fan sections that haven’t been cleaned in years and plant that needs cleaning after a refit, on internal panels, drain trays and filter sections.
In a village or hamlet like Crockenhill, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Fixed quotes for AHU cleaning in Crockenhill
A fixed price needs a few facts first. We look at:
- One-off work versus a regular cycle
- Where the site is and how we reach it
- How big the system is
- What state the system is in
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before we start.
Asking for a quote
We can often survey from pictures. The most useful are:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Can you clean school ventilation in Crockenhill during the holidays?

Do you work in Crockenhill?

How often do AHUs need cleaning?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
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.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
How the job changes from site to site
Drain trays
Drain trays can rust and leak over time. We record their condition with photos so repairs can be planned.
Internal casing and panels
We open each section through its doors and close them securely when we are done before the unit is handed back.

How it works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, clear away and hand over the paperwork. The visit itself takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Crockenhill knowing what to expect.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- 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
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work

Common problems we fix in Crockenhill
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers
- Coils clogged with dust and debris
- Drain trays holding standing water
School buildings such as Crockenhill Primary School are typically done in the holidays, so classrooms are not disturbed.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
- Keep inspection doors on the unit in good order
- Note any water around the unit or leaks below it
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
