AHU cleaning for kitchens and businesses in Hadham Cross
Our AHU cleans for sites in Hadham Cross cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after pictures in a report. If you have leaves and litter drawn into the unit and dirty fans and fan housings, we can help.
Work in a small place like Hadham Cross starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What we are called out for in Hadham Cross
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
It’s time to book a visit if you see:
- Air handling units never cleaned inside
- Intake sections clogged with outdoor debris
- Dirty fans and fan housings
- Plant that needs cleaning after a refit
If you run a surgery, dental practice or care home near Hadham Cross, clean ventilation matters as much to you as to a hospital like Herts and Essex Hospital (about 4.7 miles east).
What your quote should include

Questions from Hadham Cross
Can you clean school ventilation in Hadham Cross during the holidays?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hadham Cross. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
Can you come to Hadham Cross after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Hadham Cross can fit around your hours. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Can you price the work without visiting?
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.
What we do, step by step
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. In a small place like Hadham Cross, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
- Let us know when the site is closed or quiet
Ask for a quote
Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What affects the quote in Hadham Cross
A fixed price needs a few facts first. We look at:
- Whether we need access equipment or extra panels
- When the work can happen, such as evenings, overnight or weekends
- A single visit or a regular plan
- The scale of the work
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
Helping us quote
To speed up the quote, please include:
- The roof, plant room or outside wall the system runs to
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
- Your last certificate, test record or report

For landlords and multi-site operators
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.

Leave it or put it right?
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. It’s simpler to plan the work at Hadham Cross now than to arrange it in a hurry later.
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, phone us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Stick to the filter change plan
- Keep the area around the fresh air intake clear
- Flag stale or damp smells in the supply air
- Note any water around the unit or leaks below it
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
