Air duct cleaning cost: what are you paying for?

Air duct cleaning prices: indications for homes and commercial buildings

There is no official price list. What does exist are price indications from quote platforms and cleaning companies in the Netherlands. They vary by source, but together they paint a clear picture: residential work has a fairly fixed price range, commercial work does not.

Please note: these are amounts published by third parties. They say nothing about what a specific company will charge you, and they assume a normal level of contamination. For the difference between a standard home system and a heat recovery system, see our page on MVHR duct cleaning.

What determines the duct cleaning price in a commercial building?

For commercial jobs, hardly anyone works with a fixed price. One cleaning company lists the building type, the number and length of the ducts, the degree of contamination and accessibility as the main price factors. In practice, a few technical points come on top of that.

What the steps of a professional job look like is explained in the duct cleaning method. Once you know those steps, you are in a much better position to judge a quote.

Why commercial duct cleaning is almost always a tailored job

An office, care facility or commercial kitchen usually has an air handling unit, main ducts, branches and dozens of valves. Two buildings with the same floor area can have completely different ductwork. That is why a serious provider starts with an inspection, often with a camera and sometimes with swab samples, assessed against EN 15780 and against the requirements of the insurer.

In the hospitality sector the burden of proof is added to this. According to KHN (Royal Dutch Hospitality Association), a clean duct must be demonstrable through reporting, photos and a certificate. Whoever pays for the job is therefore paying not only for the cleaning but also for the documentation. More about grease in kitchen ducts can be found under kitchen extract duct cleaning.

• Before: inspection, inventory and a written scope of work.
• During: sealing, negative pressure, cleaning.
• After: measurement, photos and a report.

When you request quotes, ask each provider to split the price into these three phases. That makes it immediately visible whether one quote is cheaper because it simply leaves out the inspection or the report.

Which costs stay hidden when you let the ducts get dirty?

Not cleaning looks free, but it rarely is. The costs shift towards energy, comfort and risk. A few examples backed by sources:

• Less air: in a laboratory study of an MVHR unit (Energies, 2025), heavily contaminated filters delivered 37% less supply air. Power consumption fell slightly, so the main effect is under-ventilation.
• More resistance: Milieu Centraal (Dutch public information centre) points out that dirty filters create more resistance, so the fan motor has to work harder.
• Productivity: according to the World Green Building Council, better indoor air quality can raise productivity by 8 to 11%.
• Fire risk in kitchens: according to Rabobank and KHN, grease in extract ducts is highly flammable. Fire insurers demand regular maintenance.
• Legal duty: Article 6.2 of the Working Conditions Decree (Arbobesluit) requires sufficient uncontaminated air and installations that are always ready for use.

Not all of these items can be expressed in euros, but they do belong in your assessment. How often cleaning makes sense is covered in the guide on how often to clean air ducts.

Outsourcing or your own equipment: when does a machine pay off?

For a single home or one small building, outsourcing is almost always the logical choice. Your own equipment becomes interesting when you clean often, clean a lot or work at several locations. Think of a facilities team responsible for several buildings, an installer with maintenance contracts or a cleaning company that wants to add the service. For that last group there is a separate page with installers who clean ductwork.

If you are torn between the two routes, also read about in house or outsourced duct cleaning. That page explains what you are allowed and able to do yourself and what is better left to a specialist.

Fictional example: ventilation duct cleaning cost versus owning equipment

This is a fictional worked example. The quantities are made up to show the calculation, the price per unit comes from the range published by Deep Clean Services (€150 to €350 per unit for smaller commercial buildings) and we leave the machine price open: price on request.

Suppose a facility services company manages buildings with a combined 20 units and wants them cleaned every year.

The rule of thumb: payback period in years = M divided by (annual outsourcing cost minus your own annual cost). If your own costs are, for example, €1,500 a year and outsourcing costs €3,000 to €7,000, you save €1,500 to €5,500 a year. Divide your quoted price M by that amount and you know after how many years the machine pays for itself in this example.

Complete the sum with your own quantities and a real quote. If you clean twice a year, both annual amounts roughly double, the difference grows and the payback period becomes shorter.

Which equipment suits your ducts and budget?

The choice of machine depends on diameter, length and bends. The duct cleaning kit from Lamers offers four routes:

Many metres and larger ducts point to the Electric duct brushing machine. Short, small ducts and a smaller budget point rather to drill driven duct cleaner. For ducts that a brush cannot get through, the air nozzle duct cleaning is the intended tool. If you want to know whether PD2 duct cleaner suits your situation, ask for the specifications.

How to compare duct cleaning quotes fairly

Quotes often differ widely because providers include different things. Put them side by side using this checklist:

1. Was an inspection carried out beforehand, and was it done with a camera or only visually?
2. Which ducts and units are included, including the air handling unit and the valves?
3. Will the ducts be sealed and put under negative pressure with filtration?
4. Which method will be used: brush, compressed air or wet cleaning?
5. Will there be a measurement afterwards, and is a report with photos included?
6. Are fitting access hatches and disposing of the debris included?

Want to make the same comparison for buying a machine? Then send in the diameters, duct lengths, number of bends and your intended frequency when you duct cleaning advice. Lamers can then advise on the right machine and send a tailored price.
