How we handle AHU cleaning in Heart's Delight
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. We’re often asked to deal with rooms that smell stuffy when the system runs and dust-coated heating and cooling coils, on filter sections, dampers and louvres and internal panels.
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.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Your questions about AHU cleaning in Heart's Delight
Is Heart's Delight within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can ventilation in schools around Heart's Delight be cleaned out of term?
Yes, holiday work suits schools best. Around Heart's Delight, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Just give us a ring on 0345 646 2711, or send details by email with your term dates and we will plan around them.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What should I send you?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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, and that is where we come in.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building to keep disruption down.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Book the next check in line with the report
- Note any water around the unit or leaks below it
- Keep filter changes on time and recorded
- Look at the condensate drain whenever the unit is serviced
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
Part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. Access is planned during the survey so the quote reflects it.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
When to call us in Heart's Delight
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Look out for these warning signs:
- Dirty coils holding back the airflow
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
If you manage a school such as Barham Church of England Primary School, ventilation cleaning is best booked for the holidays.
Questions to ask before booking
- Whether VAT is included
- Whether the work can be done while the site is closed

- The fan and drain tray are cleaned and the drain checked.
