AHU cleaning in Blendworth, done properly
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you have dirty fans and fan housings and plant that has been serviced but not cleaned, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

When to call us in Blendworth
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
What we’re most often called out for:
- Dirty fans and fan housings
- Blocked condensate drains and slimy trays
- Rooms that smell stuffy when the system runs
- Plant that has been serviced but not cleaned

What to look for in a quote
- Exactly which parts of the system are covered
- Which accreditations they hold, and whether you can check them
- What paperwork you get at the end
- When they can work, and whether that is outside your opening hours

Multi-site and managed buildings
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.

The process
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes one overnight shift for many single units, with bigger plant phased. If the van will struggle with a lane or gateway near Blendworth, let us know and we’ll plan around it.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
Getting a quote
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 photos, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
Blendworth: your questions answered
Do you work overnight in Blendworth?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
Is Blendworth within the area you cover?
Yes, we work in villages as well as towns, and Blendworth is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
What happens to the waste?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
- Keep the certificate and photo report with the plant records
- Keep the area around the fresh air intake clear
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Fixed quotes for AHU cleaning in Blendworth
The price is fixed before any work begins. It takes into account:
- How easy every part is to reach
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- The condition we find in the survey
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What we need to know
When you contact us, it’s useful to have:
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
- The postcode and the type of business
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Why act early in Blendworth
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that doesn’t feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. Planning a trip to Blendworth ahead is easier for everyone than a rushed one.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
