Long Sutton AHU cleaning
Our technicians work in Long Sutton on AHU cleaning. Fixed quotes, work around your opening hours and photo reports as standard.
- Dirty filters cutting the airflow
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
Aftercare tips
Here’s the after-treatment advice, in brief:
- Watch for drips or damp patches near the plant
- Keep the certificate and photo report with the plant records
- Look at the condensate drain whenever the unit is serviced
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
How we handle AHU cleaning in Long Sutton
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers dampers and louvres, filter sections and heating and cooling coils, and people most often call us about leaves and litter drawn into the unit and dust-coated heating and cooling coils.
Somewhere as small as Long Sutton, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
When something else is needed
Some problems need a different service or another trade:
- Building management system faults
- Airflow problems caused by the system’s design
- Dirty ducts beyond the unit itself
Not sure which it is? You can phone us on 0345 646 2711 or drop us a line and we’ll tell you honestly.
Parts of the system we cover

How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- Whether several sites go on one quote
- The scale of the work
- The condition we find in the survey
- Travel, parking and unloading
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Helping us quote
To help us quote quickly, send us:
- Wide pictures of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- The paperwork from the last visit, if you have it
Quotes are quick. 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.
Questions from Long Sutton
Do you cover Long Sutton for AHU cleaning?
Yes, Long Sutton is within the area we cover across London and the South East. To start, call 0345 646 2711 or drop us a line with a few pictures of the system.
Do you work in villages like Long Sutton?
Yes, Long Sutton is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Can you price the work without visiting?
Yes, where the pictures show enough. If not, a site survey comes first, and the quote follows that.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, give us a ring on 0345 646 2711, or email photos and tell us about the site and its opening hours.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
How long does it take to clean an air handling unit?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, out of hours if needed.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.

When to call us in Long Sutton
Whatever surrounds a building in Long Sutton, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
Common reasons sites call us include:
- Air handling units with blocked filters
- Stale or musty smells from the ventilation
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
Wherever a school like Long Sutton Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. If you can send photos, we can arrive in Long Sutton knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Clear loose items from the work area
- Plan for cooking equipment or plant to be off before we arrive
- Mention any locked doors, roof access or ceiling voids
Ask for a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
