AHU cleaning for kitchens and businesses in Hartwell
Our AHU cleaning covers sites in Hartwell and the rest of Buckinghamshire, 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. If you have odours coming through the supply air and plant that needs cleaning after a refit, we can put it right.
Somewhere as small as Hartwell, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Duct Doctor has been trading since 2009, as 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.

What happens on the day
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to Hartwell and turn up when the site is quiet.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site
- Mention any parking or loading restrictions
Ask for a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.

- Drain trays holding standing water
- Plant that has been serviced but not cleaned
- Rooms that smell stuffy when the system runs
- Dust-coated heating and cooling coils
If you manage a school such as Stone Church of England Combined School, ventilation cleaning is best booked for the holidays.

Why act early in Hartwell
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. If the system at a site near Hartwell fails, there may be nowhere nearby to move to.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

Other services in Hartwell
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
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.
How we price AHU cleaning
The price is fixed before any work begins. It takes into account:
- Where the site is and how we reach it
- Whether it’s a one-off visit or part of a schedule
- How easy every part is to reach
- The times the site is available
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before we start.
Asking for a quote
Before you ask for a quote, gather:
- When the site is open and when it’s quiet
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or email photos.
