AHU cleaning across Titmore Green

Questions from Titmore Green

Can ventilation in schools around Titmore Green be cleaned out of term?

Yes, and it’s the easiest time to do it. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Titmore Green. Tell us your holiday dates and we will book the visit for when the site is empty.

Can you get to a site in Titmore Green?

Yes, Titmore Green is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.

Can you clean the ducts connected to the AHU?

Yes. We clean supply and extract ductwork to TR19® Air as well. It’s often worth doing both at once, and we can survey both on the same visit.

How much notice do you need?

For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.

Do you offer emergency callouts?

Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.

Can you set up regular visits?

Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.

Do you look at the system first?

Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

How often do AHUs need cleaning?

Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.

AHU cleaning for kitchens and businesses in Titmore Green

We clean air handling units for buildings in Titmore Green and across Hertfordshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We’re often asked to deal with filters that are clogged or overdue and blocked condensate drains and slimy trays, on heating and cooling coils, drain trays and supply and extract fans.

Work in a small place like Titmore Green starts with agreeing access and timings.

Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Part by part

Rooftop and plant room units

Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey so the quote reflects it.

Internal casing and panels

We open each section through its doors and close them securely when we’re done before the unit is handed back.

Why act early in Titmore Green

Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. Equipment tucked in a roof space or outbuilding near Titmore Green rarely gets looked at unless someone books it.

Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.

Why us?

  • Out-of-hours work and a 24/7 emergency line
  • Fully insured
  • Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
  • Fixed quotes from a survey or pictures

In-house cleaning or a specialist?

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 they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.

What AHU cleaning looks like in Titmore Green

There are about 5 schools, colleges and universities and about 7 hospitals, care homes and childcare premises on the FSA’s food hygiene register in Titmore Green and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Lister Hospital is the nearest hospital, about 1.1 miles east of Titmore Green. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. About 30 miles out from central London, Titmore Green is part of the South East area we work across. The visit is fixed around your opening hours, not ours.

For schools like Wymondley Junior Mixed and Infant School, the holidays are the usual time to inspect and clean ventilation.

How we price AHU cleaning

The survey tells us what the work involves. We look at:

  • How many systems or sites are involved
  • One-off work versus a regular cycle
  • When the work can happen, such as evenings, overnight or weekends
  • The size of the system

What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

Helping us quote

What to send for a quote:

  • Any previous report or certificate
  • How we’d reach plant on a roof or in a plant room
  • The times we could work without disrupting the site
  • Detail shots of panels, filters and grilles

To get a fixed quote, call us on 0345 646 2711 or use the quote form with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.

Multi-site and managed buildings

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.

From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

When to call us in Titmore Green

Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.

Common reasons sites call us are:

  • Condensate trays that will not empty
  • Dirty coils holding back the airflow
  • Units needing a clean before a new tenant or handover
  • Air handling units with blocked filters

Healthcare buildings such as Lister Hospital, about 1.1 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Titmore Green, yours matters too.

Questions to ask before booking

The process

At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Titmore Green run smoothly.

  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. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

How to prepare

  • Mention any sign-in, permit or induction we need
  • Make sure someone can let us in and lock up afterwards
  • Mention any parking or loading restrictions

Getting a quote

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
