About our AHU cleaning in Jacobs Well
Where a building in Jacobs Well has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. We’re often asked to deal with units that have only ever had filter changes and fan sections that haven’t been cleaned in years, on dampers and louvres, internal panels and supply and extract fans.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Between visits
To keep the system working properly between visits:
- Book the next check in line with the report
- Keep the area around the fresh air intake clear
- Note any water around the unit or leaks below it
- Keep the certificate and photo report with the plant records
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

How the job changes from site to site
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
FAQs for Jacobs Well
Can you come to Jacobs Well after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Jacobs Well needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Is Jacobs Well within the area you cover?
Yes, Jacobs Well is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before work begins, and waste is contained as we go. At the end, the area is cleaned down.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
How much notice do you need?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How long will the unit be out of action?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, so give us a ring on 0345 646 2711 or drop us a line to talk it through.
Fixed quotes for AHU cleaning in Jacobs Well

When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before work begins.

Why it’s worth doing now in Jacobs Well
Leave an AHU uncleaned and the dirt doesn’t stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. It’s simpler to plan the work at Jacobs Well now than to arrange it in a hurry later.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
What we are called out for in Jacobs Well
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Signs it’s time to call us include:
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
- Coils clogged with dust and debris
- Units that have only ever had filter changes
Healthcare ventilation, from large hospitals like St. Luke’s Hospital (about 2.2 miles south) to small clinics, depends on clean filters, coils and ducts.

How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes one overnight shift for many single units, with bigger plant phased. Seeing the system in photos first means the trip to Jacobs Well can be planned properly.
- We survey the unit from pictures or on site and agree what’s included.
- 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.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload

Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.
