Signs it’s time to call us include:
- Plant that has been serviced but not cleaned
- Dust-coated heating and cooling coils
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers

AHU cleaning in Sidlow, done properly
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 dirty filters cutting the airflow and coils clogged with dust and debris, we can put it right, from heating and cooling coils, filter sections and supply and extract fans onwards.
Work in a small place like Sidlow starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Sidlow: your questions answered
Do you do school ventilation cleaning in Sidlow in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 3 schools, colleges and universities with registered kitchens within about a mile and a half of Sidlow. Send us your term dates when you call 0345 646 2711 or use the quote form, and we’ll fit the work in.
Can the work in Sidlow be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Sidlow can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you offer maintenance contracts?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Is there a report after cleaning?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What happens to the waste?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and we will suggest an interval after the first clean.
Can you look after several sites?
Yes. Send the list of sites and the work at each and we’ll quote them together.
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Sidlow knowing what to expect.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Clear loose items from the work area
- Let us know about parking and loading
Ask for a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

AHU cleaning around Sidlow

What the work involves, part by part
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
What happens if it’s left?
Stuffy rooms and stale smells in a building in Sidlow can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Rural sites cannot always move to another kitchen or room when something fails.
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.

Fixed quotes for AHU cleaning in Sidlow
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- The scale of the work
- Whether several sites go on one quote
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before work begins.
What to send for a quote
When you call or email, it’s useful to have:
- A few general shots of the system
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.
Managing agents and facilities teams in Sidlow
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
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.
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Watch for drips or damp patches near the plant
- Do not ignore odours coming through the grilles
- Keep filter changes on time and recorded
- Don’t store bins or materials near the intake
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
