Air handling unit cleaning in Perry, Kent
For air handling unit cleaning in Perry, one call is all it takes: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- Dust built up on fan impellers

- Coils clogged with dust and debris
Landlords, agents and facilities managers
From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
AHU cleaning in Perry, done properly
Our AHU cleaning covers sites in Perry and the rest of Kent, 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. The work covers dampers and louvres, heating and cooling coils and supply and extract fans, and common reasons people get in touch are coils clogged with dust and debris and intake sections clogged with outdoor debris.
In a village or hamlet like Perry, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Ventilation in Perry buildings
About 5.6 miles west of Perry is St Martins Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. About 59 miles out from central London, Perry is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
If you run a surgery, dental practice or care home near Perry, clean ventilation matters as much to you as to a hospital like St Martins Hospital (about 5.6 miles west).

How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. If the van will struggle with a lane or gateway near Perry, let us know and we’ll plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Tell us the best time to work, such as after service or at a weekend
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Different parts, different methods
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
When something else is needed
Not every problem is solved by AHU cleaning, and we will tell you before any work starts. It won’t put right:
- Ductwork downstream of the unit, which is a separate clean
- Leaking heating or cooling coils
- Ventilation that was badly designed in the first place
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we will give you a straight answer before booking.

Why it’s worth doing now in Perry
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A fault that closes a site in a village like Perry affects everyone who depends on it.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
Why choose Duct Doctor in Perry
- Ventilation hygiene specialists since 2009
- Fully insured
- Fixed quotes, usually within one working day
- CHAS and SafeContractor accredited, with ISO 9001
Common problems we fix in Perry
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Clients typically contact us when they notice one of these:
- Stale or musty smells from the ventilation
- Units that have only ever had filter changes
- Debris and leaves in the fresh air intake
- Dust built up on fan impellers
Wherever a school like Preston Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- If they look at the system before pricing
- Whether VAT is included
- What happens if part of the system cannot be accessed
- Proof of accreditation you can verify
How we price AHU cleaning
Before we fix a price, we need to know a few things. We check:
- Travel, parking and unloading
- The times the site is available
- Any permits to work or inductions
- What state the system is in
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711, or email photos, and we’ll talk you through it.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- A few general shots of the system
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Perry questions
Do you cover smaller places like Perry?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Is Perry in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Perry included. You can call us on 0345 646 2711 or send us an email and let us know what needs doing.
Do you need to switch the unit off?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
What’s included in an AHU clean?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
