About our AHU cleaning in Combe
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. If you are dealing with coils clogged with dust and debris and plant that needs cleaning after a refit, we can help, from heating and cooling coils, drain trays and filter sections onwards.
Work in a small place like Combe starts with agreeing access and timings.
Duct Doctor has 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.

Yes. Combe is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.

Aftercare tips
Once we have finished, these simple steps help:
- Watch for drips or damp patches near the plant
- Check the drain tray is emptying during routine visits
- Book the next check in line with the report
- Flag stale or damp smells in the supply air
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Common problems we fix in Combe
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 one of these:
- Odours coming through the supply air
- Fan sections that haven’t been cleaned in years
- Debris and leaves in the fresh air intake
- Dirty coils holding back the airflow
School buildings such as Combe CofE Primary School are usually done in the holidays, so classrooms are not disturbed.

What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
For landlords and multi-site operators
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
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 can quote for the whole system.

- How many systems or sites are involved
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.

- The site address and the type of premises
- Detail shots of panels, filters and grilles
- Your opening hours and when the area is out of use
- Wide pictures of the system and the area around it
Getting a quote does not take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
What we do, step by step
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a village or hamlet like Combe, tell us about narrow lanes, gates and parking when you book.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.

- Allow time for equipment near the work to be turned off and cool down
- Mention any parking or loading restrictions
