AHU cleaning in Hambledon
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. Typical jobs include dirty coils holding back the airflow and rooms that smell stuffy when the system runs, across drain trays, internal panels and filter sections.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.

How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Signs you need AHU cleaning in Hambledon
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
If you notice any of these, it’s worth a diagnosis:
- Dust built up on fan impellers
- Dust-coated heating and cooling coils
- Filters that are clogged or overdue
- Plant that has been serviced but not cleaned
Classrooms and halls at schools such as Hambledon Primary School are easiest to work in when pupils are away.
What your quote should include
- What’s included in the scope, part by part
- Which accreditations they hold, and whether you can check them
- Whether a survey comes first
- How areas they cannot reach will be recorded
What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. It’s simpler to plan the work at Hambledon now than to arrange it in a hurry later.
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 go through it with you.

What we do, step by step

- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.

How to get a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before we start.
Advice
What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Between visits
So the system stays in good health:
- Do not ignore odours coming through the grilles
- Do not store bins or materials near the intake
- Report stiff or damaged access doors
- Diary the inspection date recommended in the report
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Fixed quotes for AHU cleaning in Hambledon
Your quote is based on your site. We consider:
- Parking and loading at the site
- Whether several sites go on one quote
- A single visit or a regular plan
- How easy every part is to reach
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.
What to send for a quote
What to send for a quote:
- A few general shots of the system
- The times we could work without disrupting the site
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
