AHU cleaning in Paslow Wood Common, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers filter sections, internal panels and dampers and louvres, and common reasons people get in touch are air handling units never cleaned inside and plant that needs cleaning after a refit.
In a village or hamlet like Paslow Wood Common, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Mechanical faults with motors, belts or bearings
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.
Where we work
- Filter sections

What affects the cost of AHU cleaning
The quote reflects the site in front of us. We consider:
- Site rules, permits and inductions
- Whether several sites go on one quote
- Travel, parking and unloading
- The scale of the work
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before work begins.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

What else we do in Paslow Wood Common
How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. The timing of a visit to Paslow Wood Common is set by you, and the travel is our side of the planning.
- We survey the unit from pictures or on site and agree what’s included.
- 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.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Why it’s worth doing now in Paslow Wood Common
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. It’s simpler to plan the work at Paslow Wood Common now than to arrange it in a hurry later.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.
