About our AHU cleaning in Gillingham

Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. Typical jobs include dust-coated heating and cooling coils and drain trays holding standing water, across supply and extract fans, drain trays and heating and cooling coils.

Larger buildings in Gillingham can have several air handling units serving different floors. Filters, coils, drain trays and fans all need cleaning, and standing water in a drain tray is a common finding.

Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What happens if it’s left?

Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, especially where there’s been moisture. Waiting rarely makes the work in Gillingham smaller.

What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before we start.

Honest limits

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

  • Building management system faults
  • The supply and extract ducts, quoted separately
  • Ventilation that was badly designed in the first place

If you are not sure, just ring 0345 646 2711 or email us and we will give you a straight answer.

Where we work

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

What affects the cost of AHU cleaning

A fixed price needs a few facts first. We check:

  • How easy every part is to reach
  • Working hours and out-of-hours timing
  • The scale of the work
  • What state the system is in

One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.

Helping us quote

When you call or email, it’s useful to have:

  • A few general shots of the system
  • Close-ups of filters, grilles, hatches or access panels
  • Where the site is and what kind of site it is
  • Anything you’ve noticed, such as smells, noise, drips or poor airflow

Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711 or drop us a line.

FAQs for Gillingham

Can a school’s ventilation in Gillingham be done out of term time?

Yes, out-of-term visits are normal for schools. Around Gillingham, the Food Standards Agency lists about 17 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Can you do AHU cleaning in Gillingham?

Yes, we work in Gillingham and the places around it. Get in touch with the details and we will arrange a survey.

How far ahead should we book?

The more notice, the better, especially for out-of-hours work. We usually quote within one working day, and emergencies are covered by our 24/7 line.

What about areas you can’t get to?

Anything we can’t reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.

What do you need from me for a quote?

Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call 0345 646 2711 or use the quote form.

Do you survey before quoting?

Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.

Do you have a 24/7 line?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

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.

Part by part

Fans and fan sections

The fan section is cleaned with the unit switched off and isolated in agreement with the site.

Internal casing and panels

The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.

What we do, step by step

We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes one overnight shift for many single units, with bigger plant phased. Where a site in Gillingham has more than one system, we can take them one at a time to keep the rest running.

  1. We look at the unit and the plant area during the survey.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  4. Coils and trays are cleaned and the condensate drain cleared.
  5. We close every panel, hand the unit back and send the report and certificate.

Before we arrive

  • Clear the space around the work
  • Tell us the best time to work, such as after service or at a weekend
  • Plan for cooking equipment or plant to be off before we arrive

Related advice

Do you need AHU cleaning in Gillingham?

Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.

Keep an eye out for these warning signs:

  • Intake sections clogged with outdoor debris
  • Air handling units due a clean after building work
  • Stale or musty smells from the ventilation
  • Dirty coils holding back the airflow

Classrooms and halls at schools such as Featherby Junior School are easiest to work in when pupils are away.

Before booking anyone

  • What hours they’ll be on site
  • When the next visit should be, and why
  • If they look at the system before pricing
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor

How to choose an extract cleaning contractor

Aftercare tips

Good habits slow the build-up between visits. Our tips:

  • Flag stale or damp smells in the supply air
  • Change filters on schedule and log each change
  • Book the next check in line with the report
  • Do not store bins or materials near the intake

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.

Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
