Leave it or put it right?

A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. In a smaller place like Sutton Courtenay, a site that has to close is felt quickly.

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

How the visit works

Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. Your opening hours decide when we come to Sutton Courtenay, not ours.

  1. We look at the unit and the plant area during the survey.
  2. The area is protected and the unit made safe.
  3. Each section is cleaned of dust, debris and slime.
  4. We clean the coils and clear the tray and drain.
  5. The unit is closed up and handed back, with a report to follow.

How to prepare

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Tell us the best time to work, such as after service or at a weekend
  • Clear the space around the work

Advice

Common problems we fix in Sutton Courtenay

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.

Keep an eye out for these warning signs:

  • Air handling units due a clean after building work
  • Units that have only ever had filter changes
  • Air handling units with blocked filters
  • Debris and leaves in the fresh air intake

If you manage a school such as Sutton Courtenay Church of England Primary School, ventilation cleaning is best booked for the holidays.

Before you book anyone

  • What paperwork you get at the end
  • What insurance they carry
  • Exactly which parts of the system are covered
  • Which accreditations they hold, and whether you can check them

Questions from Sutton Courtenay

Do you do school ventilation cleaning in Sutton Courtenay in the summer holidays?

Yes, holiday work suits schools best. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Sutton Courtenay, it pays to plan holiday dates ahead. Send us your term dates when you call us on 0345 646 2711, or email photos, and we’ll fit the work in.

Do you cover smaller places like Sutton Courtenay?

Yes, Sutton Courtenay is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.

How much does AHU cleaning cost?

Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.

Which parts of an air handling unit do you clean?

Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.

Where does the waste go?

We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.

Which sectors do you work in?

All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.

How long does an AHU clean take?

The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, so call us on 0345 646 2711, or email photos to talk it through.

When something else is needed

AHU cleaning cannot fix everything, and we’ll tell you before any work starts. It will not put right:

  • Leaking heating or cooling coils
  • Controls and BMS settings that run the unit
  • Ductwork downstream of the unit, which is a separate clean

Not sure which it is? You can call us on 0345 646 2711, or send details by email and we’ll tell you honestly.

Parts of the system we cover

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

In-house cleaning or a specialist?

Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.

In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

What affects the cost of AHU cleaning

A fixed price needs a few facts first. We look at:

  • The condition of the system
  • A single visit or a regular plan
  • Where the site is and how we reach it
  • The number of sites or systems

We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or drop us a line, and we will explain what it covers.

Helping us quote

To help us quote quickly, please include:

  • The roof, plant room or outside wall the system runs to
  • Where the site is and what kind of site it is
  • Problems your staff have spotted
  • Your last certificate, test record or report

Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
