Heston AHU cleaning
Need AHU cleaning in Heston? We survey first, give you a fixed quote and work around your opening hours, then sign off with a report and pictures.
- Plant that has been serviced but not cleaned
- Dust built up on fan impellers
- Air handling units due a clean after building work
Between visits
How long the results last depends on use and care. We suggest:
- Change filters on schedule and log each change
- Make sure condensate is draining away
- Don’t store bins or materials near the intake
- Make sure the unit’s access doors open easily
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
How we handle AHU cleaning in Heston
We clean air handling units for buildings in Heston and across Greater London, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Common call-outs are for filters that are clogged or overdue and fan sections that haven’t been cleaned in years, on filter sections, dampers and louvres and drain trays.
London buildings tend to keep their plant on the roof or below ground, so ventilation cleaning in Heston is normally planned out of hours. Loading and parking are planned with the building first.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

What staff can safely do
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Heston buildings and their air
The FSA’s food hygiene register lists about 37 schools, colleges and universities, about 44 caring premises (care homes, nurseries and hospitals) and about 15 hotels and B&Bs with registered kitchens or food service within 1.5 miles or so of the middle of Heston. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Getting kit to a London plant room normally means lifts, stairs and an agreed loading slot. About 1.2 miles south of Heston is Hounslow Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
For schools like Westbrook Primary School, the holidays are the usual time to inspect and clean ventilation.
Heston is about 2 miles south of Southall, in Greater London. Wherever you are in the TW5 postcode area, we can carry out AHU cleaning at your premises. Our Greater London coverage runs to 764 places, and Heston is one of them. London is in our area too, about 12 miles from Heston.

Local landmarks in Heston
Typical jobs here are in premises near Inwood Park, The Plough Public House and Heston Community School, among other places. Heston’s nearest station is Southall station, about 1.4 miles north. A little further out are Museum of Army Music (2.4 miles south-east) and Treaty Centre (1.3 miles south-east). Open spaces near Heston include Northala Fields and Crane Meadows.
When to call us in Heston
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
These are the problems we see most often:
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
- Fan sections that haven’t been cleaned in years
Healthcare buildings such as Hounslow Hospital, about 1.2 miles south, depend on their ventilation; if you manage a surgery, clinic or care home near Heston, yours matters too.

Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Managing agents and facilities teams in Heston
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes from a few hours for a compact unit to a day or more for a large one. We fit London jobs around the building rather than the other way round, so a visit in Heston is usually out of hours.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
Get a fixed quote
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before work begins.

What affects the cost of AHU cleaning
You will get a fixed price before we start. It takes into account:
- Working hours and out-of-hours timing
- A single visit or a regular plan
- Where the site is and how we reach it
- The condition of the system
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Problems your staff have spotted
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then phone us on 0345 646 2711, or send details by email.
FAQs for Heston
Does London parking affect a job in Heston?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Can you clean school ventilation in Heston during the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 37 schools and colleges with food registrations within roughly a mile and a half of Heston. Booking early in the term gives the best choice of holiday dates.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
What does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711, or send details by email and tell us about the site and its opening hours.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.
