Air handling unit cleaning in Lordington, West Sussex
Cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces for commercial sites in Lordington and across West Sussex. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Units that have only ever had filter changes
- Dirty fans and fan housings
- Drain trays holding standing water
Between visits
Once we’ve finished, these simple steps help:
- Keep the certificate and photo report with the plant records
- Book the next check in line with the report
- Keep inspection doors on the unit in good order
- Clear leaves and litter away from the intake
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
About our AHU cleaning in Lordington
If the units serving a building in Lordington have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. We’re often asked to deal with condensate trays that won’t empty and plant that needs cleaning after a refit, across drain trays, internal panels and heating and cooling coils.
In a village or hamlet like Lordington, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
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.

What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
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. That’s our job.
Signs you need AHU cleaning in Lordington
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. 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:
- Odours coming through the supply air
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Condensate trays that will not empty
School buildings such as Bourne Community College are usually done in the holidays, so classrooms are not disturbed.
Questions to ask before you book
- How they set the interval to the next visit
- Whether a written report and pictures are included
- Exactly which parts of the system are covered
- Whether the quote shows VAT
Lordington buildings and their air
Lordington’s nearest hospital, Havant War Memorial Hospital, is about 4.7 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Lordington is about 55 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.

Why it’s worth doing now in Lordington
Stuffy rooms and stale smells in a building in Lordington can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. With notice, the visit to Lordington can be fitted around your bookings and events.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
What you get with us
- Full insurance on every job
- One contact for all your sites in London and the South East
- Each visit written up, with photos
- In business since 2009
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
FAQs for Lordington
Is Lordington within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Lordington included. Photos of the system and directions to the site help us plan the visit.
Can you come to Lordington after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
How long will the unit be out of action?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we’ll confirm the time when we quote.
Do you look at the system first?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Which accreditations do you hold?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with pictures.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Lordington.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- 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.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Find the previous report, if there is one
- Allow time for equipment near the work to be turned off and cool down
- Mention any locked doors, roof access or ceiling voids
