After remotely diagnosing a problem in my system they contacted me (using a non-descript phone number and without proper introduction which sketched me out at first) and proposed a date for a technician to come and fix the problem. Tim did his job while I was working and fixed everything quickly and explained what was wrong. Thanks Tim!

Not sure if Cowboys or Pirates is the best description for this company. You'll have two choices with Vaanster: be poor or be cold. Untrustworthy thieves is the PC way of describing them.

Scammers
Scammers. They found a malfunction in the heating system that made the system consume tons of heating when was set to cooling. However, somehow they find excuses to reject the compensation requests.

I wish I could put 0 stars
I'm putting 1 star only because I cannot put 0.
This company is the definition of unprofessional: to take your money, they are always on time but if you have a simple question or worse, a problem, they always say "it's not us, it's our partner". I'm sorry but I don't care, I pay to YOU so I expect you to answer my questions. They have removed their Google reveiws because they were so bad.
I don't think enyone deserves to lose their job but I sincerely hope they go bankrupt because this is not a company, this is a scam.

Dear Victoria,
We regret that you're having this experience. Vaanster supplies sustainable heating and cooling to your home. The distribution of this heating/cooling within your home depends on the functionality of the indoor system within your home, which is owned by the property owner (landlord or home owner).
When the issue lies within this indoor system, it is indeed beyond our control, as we are a supplier of energy and not an installer, and you have to seek assistance from a service technician.
Our customer support team will contact you in order to help you allocate the right external party to get this solved.
Best regards,
Team Vaanster

I can only agree with what has been said from other reviews. I would like to add that even their website is a disaster. The "I forgot my password" function does not work. So logging in is impossible if you forget your password. I've clicked it 3 times to send me my password and the website says everytime the email has been sent but I never receive it. And no, it's not in the spam or junk folder.

I would like to thanks Vaanster support personals for their amazing service. I do live in Zaandam and recently I had a mal-function in the district heating system "warmtemeter fault". when I called the support, they took direct actions and send and engineer to check and fix the problem.
Again, thanks a lot.

How nice to hear! Thanks for this review.
Vaanster uses a poor repair company
Vaanster uses a repair company called Breman, the Breman phone staff are rude, do not call back after multiple requests, are unable to say when they will be able to call back and just say "I don't know" to every question. When they did turn up they failed to repair my heating which broke in the same way last year, the issue causes the system to use many gigajoules of (expensive) energy when the heating is turned off.
I am stuck on the phone again with promises of a phone call that doesn't happen.
