About our AHU cleaning in North Ascot
Our AHU cleaning covers sites in North Ascot and the rest of Windsor and Maidenhead, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We’re often asked to deal with units needing a clean before a new tenant or handover and leaves and litter drawn into the unit, on drain trays, filter sections and supply and extract fans.
In a smaller place like North Ascot, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Even a site near North Ascot that’s only busy part of the week needs its system checked on a schedule.
The cost depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- A system that is undersized for the building
- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings
If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think.
What the work covers
- Heating and cooling coils
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Drain trays
- Filter sections
What the work involves, part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. We protect the area below before opening them.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
What staff can safely do
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.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Your questions about AHU cleaning in North Ascot
Will you come out to North Ascot?

Can you work in North Ascot outside opening hours?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in North Ascot needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What do you need from me for a quote?

What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
How much does AHU cleaning cost in North Ascot?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote, normally ready within one working day.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too in North Ascot and across Windsor and Maidenhead. Larger estates can be phased building by building around the people who use them.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Ventilation in North Ascot buildings
Going by the FSA’s register, there are about 9 schools, colleges and universities and about 6 care, childcare and hospital premises serving food in North Ascot 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 0.5 miles south-east of North Ascot is Heatherwood Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. We cover North Ascot, about 26 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare ventilation, from large hospitals like Heatherwood Hospital (about 0.5 miles south-east) to small clinics, depends on clean filters, coils and ducts. Wherever a school like Ascot Heath Church of England Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time.

How we price AHU cleaning
The diagnosis comes before the price. The main factors are:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- Any permits to work or inductions
- Whether it’s a one-off visit or part of a schedule
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
To speed up the quote, send us:
- Any previous report or certificate
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or send details by email.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes one overnight shift for many single units, with bigger plant phased. Tell us when your site near North Ascot is quiet and the visit will be booked for then.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Mention any parking or loading restrictions
- Mention any sign-in, permit or induction we need
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
