AHU cleaning in Roffey, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers internal panels, heating and cooling coils and filter sections, and people most often call us about air handling units never cleaned inside and intake sections clogged with outdoor debris.
In a smaller place like Roffey, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
FAQs for Roffey
Can you work in Roffey outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Roffey can fit around your hours. Tell us your opening hours when you ask for a quote.
Can you get to a site in Roffey?
Yes. Villages and rural sites across the South East are part of our work, Roffey included. The journey is planned ahead, so a few details about the route help.
Can you quote from pictures?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
What happens to the waste?
We take it away when we go. While we work, it’s kept contained to keep the area clean.
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.
Are you insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How do you protect the area?
Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. Before we leave, we tidy up and clean down.
How much does AHU cleaning cost in Roffey?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll usually reply within one working day.
Do you need AHU cleaning in Roffey?
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Units needing a clean before a new tenant or handover
- Debris and leaves in the fresh air intake
- Air handling units with blocked filters
If you manage shops or offices close to Littlehaven station, a TR19® Air inspection shows whether the ductwork needs cleaning.

What we do, step by step

The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Tell us about any gates, ladders or locked plant areas at your site near Roffey when you book.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Mention any sign-in, permit or induction we need
- Name a contact who can let us in at the agreed time
- Have your last certificate or report to hand

For landlords and multi-site operators
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.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
