How the job changes from site to site
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
AHU cleaning in Dogmersfield
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. If you have stale or musty smells from the ventilation and drain trays holding standing water, we can put it right, from filter sections, dampers and louvres and internal panels onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Good records are part of the job. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Keeping the system healthy
To keep the system working properly between visits:
- Don’t ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
What a clean will not put right
AHU cleaning cannot fix everything, and we’d rather say so up front. It does not solve:
- Faulty motors, drives or bearings
- Damaged coils beyond cleaning
- Building management system faults
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly before you book.

Questions from Dogmersfield
Do you work overnight in Dogmersfield?
Yes. We work evenings, overnight and at weekends. It means the site in Dogmersfield keeps running as normal. Your opening times are the first thing we ask for.
Is AHU cleaning available in Dogmersfield?
Yes. Our area runs across London and the South East, Dogmersfield included. Get in touch with the details and we’ll arrange a survey.
Are you fully insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
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.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
When to call us in Dogmersfield
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
It’s time to book a visit if you see:
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
If you manage a school such as Dogmersfield Church of England Primary School, ventilation cleaning is best booked for the holidays.
Before you book anyone
- When they can work, and whether that’s outside your opening hours
- If they look at the system before pricing
- Whether the figure could change on the day
- Which accreditations they hold, and whether you can check them
What affects the quote in Dogmersfield
The diagnosis comes before the price. We look at:
- The condition we find in the survey
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
- Where the site is and how we reach it
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.
Asking for a quote
To help us quote quickly, send us:
- Any previous report or certificate
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
- A few general shots of the system
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

On site, it takes from a few hours for a compact unit to a day or more for a large one. If you can send pictures, we can arrive in Dogmersfield knowing what to expect.
- 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.
- We close up the unit and send the certificate and before and after photos.

- Mention any sign-in, permit or induction we need
