About our AHU cleaning in Ware

No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. Typical jobs include filters that are clogged or overdue and plant that has been serviced but not cleaned, on internal panels, supply and extract fans and filter sections.

Buildings in towns like Ware often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning, so you’re not paying for more than the system needs.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What a clean won’t put right

We’ll always give you a straight diagnosis, so here’s what AHU cleaning won’t do:

  • Airflow problems caused by the system’s design
  • Mechanical faults with motors, belts or bearings
  • Ductwork downstream of the unit, which is a separate clean

Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we will tell you honestly before booking.

What we work on in Ware

  • Filter sections
  • Drain trays
  • Internal panels
  • Dampers and louvres
  • Heating and cooling coils
  • Supply and extract fans

How the job changes from site to site

Fans and fan sections

The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.

Heating and cooling coils

A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.

Common questions in Ware

Do you work at weekends in Ware?

Yes, out-of-hours work is a big part of what we do. That way a site in Ware does not have to lose a day’s trading. When you ring 0345 646 2711, or email photos, mention when the site is quiet.

Do you clean school ventilation in Ware in the holidays?

Yes, and it’s the easiest time to do it. The FSA’s register shows about 15 schools and colleges with food registrations within roughly a mile and a half of Ware. Just call 0345 646 2711, or email photos with your term dates and we’ll plan around them.

What’s included in an AHU clean?

Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.

Can you look after several sites?

Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Each site gets its own report and pictures.

What does AHU cleaning cost?

Every site is different, so each gets its own fixed quote. To get one, ring 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.

What types of premises do you cover?

Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.

Where does the waste go?

It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.

Can you price the work without visiting?

In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.

In-house cleaning or a specialist?

Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.

Aftercare tips

A little care between visits keeps the system in better shape. Our advice:

  • Make sure condensate is draining away
  • Diary the inspection date recommended in the report
  • Stick to the filter change plan
  • Don’t ignore odours coming through the grilles

If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.

Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.

Why act early in Ware

When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. That makes the next inspection of a building in Ware simpler. A small fault found now is a quick job; the same fault found later can close the site.

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.

Landlords, agents and facilities managers

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 send the paperwork to whoever needs it.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

AHU cleaning in Ware: local notes

Going by the FSA’s register, there are about 15 schools, colleges and universities, about 15 hospitals, care homes and childcare premises and about 4 hotels, B&Bs and guest houses serving food within 1.5 miles or so of the middle of Ware. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 2.8 miles south-west of Ware is Hertford County Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. We cover Ware, about 22 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible.

If you run an office near Ware station, its supply ductwork can gather dust for years before anyone looks inside. Healthcare buildings such as Hertford County Hospital, about 2.8 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Ware, yours matters too. Wherever a school like Christ Church CofE (VA) Primary School and Nursery has ducted ventilation, a half-term visit keeps the work out of lesson time.

The process

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes from a few hours for a compact unit to a day or more for a large one. The more we can see of the system beforehand, the smoother the visit to Ware will be.

  1. First the unit is surveyed, from photos or a visit, and the scope agreed.
  2. We arrange the shutdown with your staff and sheet the area.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. We clean out the drain tray and make sure it drains.
  5. You get a TR19® certificate and a photo report.

Preparing for the visit

  • Clear the space around the work
  • Mention any parking or loading restrictions
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
