AHU cleaning for kitchens and businesses in Kelvedon
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers internal panels, supply and extract fans and filter sections, and common reasons people get in touch are blocked condensate drains and slimy trays and stale or musty smells from the ventilation.
In a smaller place like Kelvedon, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
When to call us in Kelvedon
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Keep an eye out for these warning signs:
- Dust built up on fan impellers
- Air handling units due a clean after building work
- Plant that has been serviced but not cleaned
- Dirty filters cutting the airflow
For schools like Kelvedon St Mary's Church of England Primary Academy, the holidays are the usual time to inspect and clean ventilation.
Questions to ask before you book
- Proof of accreditation you can verify
- Whether inaccessible sections are listed on the report
- How they set the interval to the next visit
- Exactly which parts of the system are covered
What affects the quote in Kelvedon
There’s no set price list, because sites vary so much. What we look at:
- How many systems or sites are involved
- Any permits to work or inductions
- The scale of the work
- Working hours and out-of-hours timing
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
Helping us quote
When you contact us, these details help:
- Problems your staff have spotted
- Detail shots of panels, filters and grilles
- Wide photos of the system and the area around it
- Your opening hours and when the area is out of use
For AHU cleaning in Kelvedon, call 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We normally send a fixed quote within one working day.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Clear leaves and litter away from the intake
- Store the TR19 paperwork where auditors can find it
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Why deal with it now?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. A site near Kelvedon that has to close at short notice is hard to cover for.
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

What happens on the day
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. For a place like Kelvedon, we load the van from the survey notes so the work can be done in one visit where possible.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Clear loose items from the work area
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
Getting a quote
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
