About our AHU cleaning in Hare Street
We clean air handling units for buildings in Hare Street and across Essex, working to TR19® Air, 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 dirty coils holding back the airflow and dirty filters cutting the airflow, across internal panels, heating and cooling coils and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

When something else is needed
We won’t sell you work that does not address the problem, so here are the limits:
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
- Damaged coils beyond cleaning
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before booking.
Where we work
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Internal panels
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare across Essex. Work can be phased by floor, building or site to keep disruption down.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Look at the condensate drain whenever the unit is serviced
- Keep the area around the fresh air intake clear
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.

Common questions in Hare Street
Can you come to Hare Street after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Will you come out to Hare Street?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. We typically quote within one working day, and emergencies are covered by our 24/7 line.
What should I send you?
A short description and a few pictures plus the address and your hours. We’ll ask for anything else we need.
Do you give a certificate after the clean?
Yes. A TR19® certificate and photo report are sent after the clean, including anything we think needs attention.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
What affects the quote in Hare Street
Your quote is based on your site. We consider:
- A single visit or a regular plan
- How big the system is
- The times the site is available
- Site requirements such as sign-in and permits
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
Getting a quote doesn’t take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Somewhere like Hare Street, lanes, gates and parking are worth mentioning in advance.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards
Getting a quote
The quickest way to a quote is to send photos: 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 we can price many jobs without a visit.

In-house cleaning or a specialist?
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, alongside our reports.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What we are called out for in Hare Street
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
It’s time to book a visit if you see:
- Drain trays holding standing water
- Plant that has been serviced but not cleaned
- Plant that needs cleaning after a refit
- Dust-coated heating and cooling coils
If you run a surgery, dental practice or care home near Hare Street, clean ventilation matters as much to you as to a hospital like St. Margaret's Hospital (about 4.6 miles north-west).
