How we handle AHU cleaning in Hazeleigh
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers drain trays, internal panels and filter sections, and common reasons people get in touch are dust built up on fan impellers and blocked condensate drains and slimy trays.
Work in a small place like Hazeleigh starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Questions from Hazeleigh
Is Hazeleigh in your area for AHU cleaning?
Yes, Hazeleigh is covered. A fixed quote usually follows within one working day of the survey details.
Do you cover smaller places like Hazeleigh?
Yes, we work in villages as well as towns, and Hazeleigh is covered. Just mention lanes, gates or anything else about the site when you book.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Different parts, different methods
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
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.

How we price AHU cleaning
We don’t publish a price list, because no two systems are the same. What we look at:
- How many systems or sites are involved
- Parking and loading at the site
- Site requirements such as sign-in and permits
- How big the system is
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
Getting a quote does not take long. Call or email with a few details and you’ll normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
When to call us in Hazeleigh
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Signs it’s time to call us include:
- Condensate trays that won’t empty
- Air handling units due a clean after building work
- Coils clogged with dust and debris
- Air handling units with blocked filters
Baddow Hospital, about 5.6 miles west, is the nearest hospital to Hazeleigh, and healthcare sites of every size need their supply air kept clean.
What to look for in a quote
- What’s included in the scope, part by part
- Whether the work can be done while the site is closed
- Whether the quote is based on a survey or photos
- Whether inaccessible sections are listed on the report
When it’s something else
To be straight with you, some problems need a different fix:
- Dirty ducts beyond the unit itself
- Mechanical faults with motors, belts or bearings
- Ventilation that was badly designed in the first place
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think.

Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Plan the next inspection before the last report gets filed away
- Note any water around the unit or leaks below it
- File each AHU report in the maintenance log
- Flag stale or damp smells in the supply air
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. The visit itself takes one overnight shift for many single units, with bigger plant phased. For a village or hamlet like Hazeleigh, tell us about narrow lanes, gates and parking when you book.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Move anything stored near the system
Ask for a quote
The quickest way to a quote is to send pictures: 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.
