- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
- Dirty coils holding back the airflow
Keeping the system healthy
To keep the system working properly between visits:
- Keep filter changes on time and recorded
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
- Make sure the unit’s access doors open easily
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
AHU cleaning in Blindley Heath, done properly
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. If you’re dealing with plant that has been serviced but not cleaned and dust built up on fan impellers, we can help, from drain trays, internal panels and heating and cooling coils onwards.
Somewhere as small as Blindley Heath, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
How it works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Blindley Heath.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms
Getting a quote
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Signs you need AHU cleaning in Blindley Heath
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Most sites get in touch after spotting something like this:
- Plant that needs cleaning after a refit
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
- Dust-coated heating and cooling coils
An inspection comes first for any ventilation job around Blindley Heath, so the cleaning matches what’s there.

Your questions about AHU cleaning in Blindley Heath
Is Blindley Heath in your area for AHU cleaning?
Yes. We work across London and the South East, and Blindley Heath is part of that. Get in touch with the details and we will arrange a survey.
Can you get to a site in Blindley Heath?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
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’re fully insured.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
