AHU cleaning in South Leigh, done properly
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. If you have air handling units due a clean after building work and dust built up on fan impellers, we can put it right.
In a village or hamlet like South Leigh, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, as 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.

South Leigh questions
Will you come out to South Leigh?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in South Leigh?
Yes, out-of-hours work is a big part of what we do. It means the site in South Leigh keeps running as normal. Your opening times are the first thing we ask for.
Do you need to switch the unit off?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Can you quote from pictures?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. If photos are not enough, we will survey first.
Is there a survey before the work?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Managing agents and facilities teams in South Leigh
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

What else we do in South Leigh
Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Our emergency line runs 24/7, but a planned visit to South Leigh is calmer for everyone.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.

Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Keep an eye out for any of the following:
- Stale or musty smells from the ventilation
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Fan sections that haven’t been cleaned in years
