AHU Cleaning in Sun Rising
AHU cleaning in Sun Rising from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Dust built up on fan impellers
- Plant that needs cleaning after a refit
- Air handling units with blocked filters
How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
How we handle AHU cleaning in Sun Rising
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers supply and extract fans, internal panels and dampers and louvres, and people most often call us about air handling units never cleaned inside and blocked condensate drains and slimy trays.
For a building in or near Sun Rising, access is agreed in advance and the visit is planned around the journey.
A written report with photos follows each visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How we price AHU cleaning
Some jobs are bigger than they look, and some smaller. The main factors:
- Parking and loading at the site
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
- Site rules, permits and inductions
We do not list prices on the website, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or drop us a line, and we’ll talk you through it.
What we need to know
When you contact us, these details help:
- Problems your staff have spotted
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
Leave it or put it right?
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Our emergency line runs 24/7, but a planned visit to Sun Rising is calmer for everyone.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call us on 0345 646 2711, or email photos for straight advice and a fixed quote.

What AHU cleaning cannot fix
Before you book, it helps to know what’s not included:
- Airflow problems caused by the system’s design
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.
What we work on in Sun Rising
- Supply and extract fans
- Internal panels
- Drain trays
- Heating and cooling coils
- Filter sections
- Dampers and louvres
Between visits
Aftercare is simple, and it helps at the next visit:
- Keep the area around the fresh air intake clear
- Note any water around the unit or leaks below it
- Book the next check in line with the report
- Make sure condensate is draining away
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.

What is TR19?

Can you quote from photos?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If pictures aren’t enough, we’ll survey first.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Managing agents and facilities teams in Sun Rising
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
What we do, step by step
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, clear away and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Sun Rising are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after photos.
