About our AHU cleaning in Milford

If the units serving a building in Milford 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. If you are dealing with air handling units never cleaned inside and debris and leaves in the fresh air intake, we can put it right, from internal panels, supply and extract fans and drain trays onwards.

Visits to a place like Milford are fitted around opening hours. The method doesn’t change: inspect first, clean, then record what was done.

Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

When to call us in Milford

An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.

Any of these means the system needs a check-up:

  • Blocked condensate drains and slimy trays
  • Debris and leaves in the fresh air intake
  • Fan sections that haven’t been cleaned in years
  • Filters that are clogged or overdue

Wherever a school like Milford School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Questions to ask before you book

  • If they look at the system before pricing
  • Whether the whole system is included, or only the parts that are easy to reach
  • What paperwork you get at the end
  • What hours they’ll be on site

Our hiring checklist

For landlords and multi-site operators

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.

We also work for facilities teams across offices, schools and healthcare across Surrey. Larger estates can be phased building by building around the people who use them.

What happens if it’s left?

A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. It’s easy to lose track of when the work was last done on a quieter site.

Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.

  • A written report with pictures after each visit

Milford buildings and their air

Going by the FSA’s register, there are about 3 hospitals, care homes and childcare premises serving food in Milford and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 1 mile east of Milford is Milford Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Milford is about 33 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.

Healthcare buildings such as Milford Hospital, about 1 mile east, depend on their ventilation; if you manage a surgery, clinic or care home near Milford, yours matters too. Workplaces around Milford (Surrey) station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.

What affects the quote in Milford

There’s no set price list, because no two systems are the same. The quote depends on:

  • The condition we find in the survey
  • When the work can happen, such as evenings, overnight or weekends
  • Any permits to work or inductions
  • Whether several sites go on one quote

You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form, and we’ll explain what it covers.

Asking for a quote

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

  • When the site is open and when it’s quiet
  • The roof, plant room or outside wall the system runs to
  • The paperwork from the last visit, if you have it
  • Wide pictures of the system and the area around it

Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.

How the visit works

There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes one overnight shift for many single units, with bigger plant phased. Your opening hours decide when we come to Milford, not ours.

  1. We survey the unit from photos or on site and agree what’s included.
  2. The unit is shut down with your site team and the area protected.
  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. We close up the unit and send the certificate and before and after pictures.

Getting ready for the visit

  • Make sure someone can let us in and lock up afterwards
  • Tell us the best time to work, such as after service or at a weekend
  • Make sure equipment near the work can be switched off and left to cool

Ask for a quote

Part by part

Internal casing and panels

Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.

Drain trays

A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.

What your team can do, and what needs us

If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.

Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
