Duct cleaning equipment: hire or buy?

Hiring or buying a duct cleaning machine: the short answer

The choice mainly depends on how often you clean ducts. A facilities team that does one building every few years will have a machine sitting on the shelf most of the time. A cleaning contractor that visits the same series of clients every year, often linked to the annual inspection, uses it week in, week out.

• Hiring suits a one off assignment, a trial or a job with a duct size you normally never come across.
• Buying suits recurring work, a steady client base and your own standard for quality and reporting.

That annual rhythm is common practice, not law. There is no statutory cleaning frequency for air ducts in the Netherlands. However, under article 6.2 of the Working Conditions Decree (Arbobesluit) ventilation installations must always be in working order, and insurers in hospitality ask for an annual inspection of the extract duct.

Comparison table: duct cleaning machine hire versus buying

If you decide to buy, the considerations per component are covered on the page about buying a duct cleaning kit.

Availability: the client will not wait for a hired machine

When you hire, you plan around someone else's diary. If an urgent job comes in, for example an office with complaints about dust coming out of the grilles, you want to be able to work that same week. With your own machine in the van, that is not even a question.

This matters even more for work tied to a fixed moment. Think of the annual inspection in a care home or a school that can only be done during the holidays. Miss that window and the job moves months down the line. If you know the duct cleaning frequency at your clients, you quickly see how many of those fixed moments there are each year.

Familiarity: why your own duct cleaner gives better results

A brushing machine feels different in every duct. How the shaft passes through a 90 degree bend, how hard you can push in a vertical duct, when to reduce the speed: you learn that by using the machine often. On the The Danduct Clean DC4 duct cleaner a solid steel shaft keeps the brush in the centre of the duct and an automatic system reverses the direction of rotation in time. That works best when you know the settings.

The choice between machines also plays a role. For small ducts and short runs you work with PD4 duct cleaner on your own power drill, with a shaft of 2.5 to 7.5 metres. If you own that combination, you know exactly which drill and which torque go with it.

With a hired machine you start from scratch every time. That costs time on the job, and time on the job is exactly what your client pays for.

Brushes under your own control: hygiene and sizing

Brushes are consumables. They wear, get dirty and lose their shape. With your own set you know where a brush comes from and which duct it was last used in. That is more than a detail: you do not want to carry dirt from a commercial kitchen into a care home.

• You choose the stiffness yourself: soft, standard or Tynex.
• You only buy the diameters you actually use, from 100 to 600 mm.
• You replace a brush when it is worn, not when the provider thinks so.

More about size and stiffness can be found under duct cleaning brushes.

Fictional example: where is the break even point between hiring and buying?

We do not quote amounts here: hire prices differ per provider and you receive the purchase price of a set on quotation. That is why you calculate the break even point with your own figures. This is how it works.

Fictional example without amounts: a cleaning contractor has fixed annual contracts with offices and schools and does one job every week. In that case the break even point is reached well within the first year. A facilities team that does one building every few years may never reach it. Do add the time that hiring costs: collecting, getting used to the machine and returning it. Those hours do not show up in the hire price, but they do show up in your planning.

Decision guide: hire a duct cleaner or buy your own?

1. Do you clean ducts more than a few times a year? Then lean towards buying.
2. Do you offer duct cleaning as a regular service alongside maintenance or inspection? Then lean towards buying.
3. Is it a one off job in a size you will never see again? Then lean towards hiring.
4. Do you want to report with your own camera and a fixed method? Then lean towards buying.
5. Not sure whether you should do the job yourself at all? Read in house or outsourced duct cleaning first.

If you want to offer duct cleaning on a structural basis, read under air duct cleaning as a service how to build that up. An overview of all machines is available under compare duct cleaning kits.
