How we handle AHU cleaning in The Willows
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have air handling units with blocked filters and dust-coated heating and cooling coils, we can put it right.
In a village or hamlet like The Willows, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

FAQs for The Willows
Can you get to a site in The Willows?
Yes. Villages and rural sites across the South East are part of our work, The Willows included. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in The Willows?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Just call 0345 646 2711 or use the quote form with your opening times and we will plan around them.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
How long does it take to clean an air handling unit?
It takes anything from half a day for one small unit to several shifts for a plant room full of them. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in The Willows and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
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 photos, so each one has its own record.
The Willows buildings and their air
About 5.6 miles south-east of The Willows is Herts and Essex Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. We cover The Willows, about 31 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.
School buildings such as Furneux Pelham Church of England School are normally done in the holidays, so classrooms aren’t disturbed. Healthcare ventilation, from large hospitals like Herts and Essex Hospital (about 5.6 miles south-east) to small clinics, depends on clean filters, coils and ducts.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Keep inspection doors on the unit in good order
- Keep the area around the fresh air intake clear
- Report water on the plant room floor
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Honest limits
AHU cleaning can’t fix everything, and we’ll tell you before we start. It will not put right:
- Controls and BMS settings that run the unit
- Airflow problems caused by the system’s design
- Ductwork downstream of the unit, which is a separate clean
If in doubt, ring 0345 646 2711 or use the quote form and we’ll say what we think before booking.

What happens if it’s left?
A clogged coil or dirty fan makes the unit work harder for the same airflow. 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. It’s simpler to plan the work at The Willows now than to arrange it in a hurry later.

Part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Fixed quotes for AHU cleaning in The Willows
Some jobs are bigger than they look, and some smaller. The main factors:
- When the work can happen, such as evenings, overnight or weekends
- The scale of the work
- What state the system is in
- Travel, parking and unloading
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will explain what it covers.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
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, the quote is fixed before any work is booked.
