AHU cleaning in New Alresford
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote before any cleaning starts. Common call-outs are for plant that has been serviced but not cleaned and dust-coated heating and cooling coils, on dampers and louvres, supply and extract fans and filter sections.
Smaller buildings around New Alresford often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Light use slows the build-up but doesn’t stop it.
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before work begins.

Fixed quotes for AHU cleaning in New Alresford
The quote reflects the site in front of us. We consider:
- When the work can happen, such as evenings, overnight or weekends
- How many systems or sites are involved
- The size of the system
- Whether we need access equipment or extra panels
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, phone us on 0345 646 2711 or send us an email for straight advice and a fixed quote.

What else we do in New Alresford
Common problems we fix in New Alresford
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Clients normally contact us when they notice one of these:
- Plant that needs cleaning after a refit
- Dirty filters cutting the airflow
- Dust built up on fan impellers
- Stale or musty smells from the ventilation
Classrooms and halls at schools such as Sun Hill Junior School are easiest to work in when pupils are away.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.

How the visit works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Your opening hours decide when we come to New Alresford, not ours.
- 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.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site

When something else is needed
We’d rather tell you now than book work that will not help, so here are the limits:
- Airflow problems caused by the system’s design
- Dirty ducts beyond the unit itself
- Building management system faults
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.

- Heating and cooling coils
- Dampers and louvres
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Your questions about AHU cleaning in New Alresford
Do you cover smaller places like New Alresford?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you clean school ventilation in New Alresford in the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 5 schools, colleges and universities with registered kitchens within about a mile and a half of New Alresford. Booking early in the term gives the best choice of holiday dates.
Can you clean the AHU out of hours?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
How often should an air handling unit be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What is TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Is a quote from photos possible?
Yes, where the photos show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
