AHU cleaning for sites in Chilbolton

Why it’s worth doing now in Chilbolton

Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Rural sites cannot always move to another kitchen or room when something fails.

Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

Why book with us

  • Accredited under CHAS and SafeContractor, with ISO 9001
  • Work around your opening hours, with 24/7 emergency cover
  • Photo reports with every job
  • Survey first, then a fixed quote

About our AHU cleaning in Chilbolton

If the units serving a building in Chilbolton have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. We’re often asked to deal with dirty coils holding back the airflow and odours coming through the supply air, across supply and extract fans, dampers and louvres and internal panels.

Somewhere as small as Chilbolton, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When to call us in Chilbolton

Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.

Clients normally contact us after spotting something like this:

  • Air handling units with blocked filters
  • Fan sections that haven’t been cleaned in years
  • Debris and leaves in the fresh air intake
  • Dust-coated heating and cooling coils

Hospitals such as Andover War Memorial Hospital (about 5 miles north-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Chilbolton are no different.

Questions to ask before booking

  • How VAT is shown on the quote
  • Proof of insurance
  • Proof of accreditation you can verify
  • Whether a written report and photos are included

Questions to ask before booking

What we do, step by step

Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Chilbolton before we set off.

  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.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Find the previous report, if there is one
  • Let us know how we reach the system, including roofs, risers and plant rooms

What a clean will not put right

A few issues sit outside what this work can do:

  • Faulty motors, drives or bearings
  • Controls and BMS settings that run the unit
  • Ductwork downstream of the unit, which is a separate clean

If you’re not sure, just ring 0345 646 2711, or send details by email and we will give you a straight answer before you book.

Parts of the system we cover

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

What the work involves, part by part

Internal casing and panels

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

Filters

Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.

Fixed quotes for AHU cleaning in Chilbolton

We don’t publish a price list, because no two systems are the same. The quote depends on:

  • Parking and loading at the site
  • The condition we find in the survey
  • Whether it’s a one-off visit or part of a schedule
  • How many systems or sites are involved

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

What to send for a quote

Before you ask for a quote, gather:

  • When the site is open and when it’s quiet
  • How we’d reach plant on a roof or in a plant room
  • Close-ups of filters, grilles, hatches or access panels
  • The paperwork from the last visit, if you have it

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
