A fantastic find! I was looking for a reliable company and stumbled upon this one by chance. I received a quote within the hour, and the installation date was set for the same day I accepted the quote—all within a remarkably short timeframe. The follow-up, explanations, and installation were all very professional. The team was great, arrived on time, and worked very cleanly. And all this at a very reasonable price. Thank you so much! 😁😊✨

I've been having my boiler serviced by them for several years now and I've always been very satisfied with their work and professionalism. Recently, I had a problem with my boiler and they helped me online, guiding me step by step so I could get it working again myself at home. Fast, efficient, and always friendly service.
Honestly, 10/10 — I highly recommend them!

I am extremely satisfied with the installation of my new boiler today. Everything was perfect, from the speed of execution to the explanations provided. I would especially like to thank the two workers; it's a shame I don't have their names. Their professionalism, efficiency, and kindness made this a very positive experience. A big thank you to them and to the company for such high-quality service!

I am very satisfied with Ilmachauf's service. The installation team was very professional, attentive, and helpful from start to finish.
They replaced my old gas boiler with a condensing boiler, and everything went very quickly, from the quote to the completion of the installation.

The work was meticulous and efficient, with clear and precise explanations at every step. The price is very reasonable considering the care taken and the quality of the work.
I will also add some photos to illustrate the result.

I highly recommend Ilmachauf for their reliability and professionalism!

I called on the Ilmachauf company, which I didn't know. I was very satisfied with the quick and efficient contact, the professionalism of the boss I met on site (and who answered all my questions each time), as well as the professionalism of his technicians who did a careful job (installation of a new boiler, lining of a chimney and installation of a radiator) and everything worked perfectly in one day, it was done! I thank them infinitely and I recommend this heating engineer with my eyes closed.

From start to finish, everything went perfectly.

Efficiency: The installation was carried out professionally, and everything works perfectly. They explained how it works and how to configure it.

Cleanliness: They cleaned up after the work was done, leaving no mess behind.

Communication: They listened attentively, provided clear explanations, and the follow-up was impeccable.

Price: Very reasonable for the quality of service provided.

In short, Ilmachauf is a serious, reliable, and responsive company. If you are looking for a competent heating engineer, don't hesitate! 5/5 without hesitation. 👍

Our old gas boiler being at the end of its life, we had made the decision to replace it at the end of the heating period so as not to repeat the nightmare that we had experienced twice following breakdowns in the middle of winter at minus 10 outside... It's strange, or perhaps it's Murphy's laws, but a boiler often breaks down when it really shouldn't. ..In any case, ours ;-) In short, we made the wise decision to wait until the end of winter to do the work. After the start of our hunt for potential candidates, our choice fell to the Ilmachauf company to install a Vaillant brand condensing boiler. The very correct quote was established within 48 hours, but we also later realized that the water hardness (46° f) did not really meet the requirements for Vaillant's warranty, so we opted for an installation of a SoluCalc CO2 softener also at the same time. The work took place yesterday morning, three highly professional men carried out the replacement of the boiler with chimney lining, as well as the installation of the water softener in just over 4 hours. I can therefore only confirm in my turn that this company is very serious and professional which is becoming rare these days. Thank you again to the whole team for your excellent intervention!

Broke down on New Year's Eve! I contacted Ilmachauf who took care of me directly.
And 24 hours later, my new boiler is already installed and functional.
And yes, there are still serious companies on a human scale.
Thanks again. M Devos

I called ILMACHAUF for a boiler replacement following a breakdown on a Sunday and by Wednesday everything was installed! The quote details the entire installation.

Concerned about privacy, punctual and diligent (they finished almost 3 hours early!), they were able to be professional despite many constraints (old house)
They provide all the explanations necessary for the proper use and maintenance of the boiler.
I recommend them to you +++

16:16 18 Dec 24

After 10 years of trouble and the visit of 4 heating engineers, ILMACHAUFF found and resolved the origin of the water flowing from the boiler..... all thanks to a visit with a camera. No one had thought about it. Three days after the diagnosis the chimney was retubed with the appropriate equipment. Speed, efficiency, cleanliness, top-notch administration, boss on site, very helpful team. Nothing to say but the opposite. It's decided: I'm going to visit them for the interview too. Highly recommended!!! Very sincerely, ILMACHAUFF reconciled me with the heating engineers

Efficient and serious company. Contacted on a Saturday, the replacement of our boiler took place the following Thursday in accordance with the quote provided. In addition to sound advice during the installation of the boiler, administrative follow-up (invoice and PEB certificate) is seriously ensured. Thank you so much !

We called on them to replace our boiler with a condensing boiler.

They were super responsive and offered us an appointment very quickly.

Very punctual and professional on the day of installation.
Work done neatly and in accordance with the estimate.
And above all, the follow-up for the production of documents (PEB) was done quite quickly.

We can only highly recommend this company.

The boss quickly came to estimate the work to be done. Already at that time he was attentive to needs. The quote amount was done very quickly and did not change following small adjustments that I requested. I wanted a non-Vaillant but netatmo thermostat that I had bought.... "No worries, we'll hook it up for you." There is a small valve leaking..." no worries, we will change it for you "🙂. The contact was friendly and quick. On the day of the installation, several of them came. Always attentive to needs, with sincere kindness and fast and careful work was done.
They have earned my trust and I am confident that if one day I have a problem with the boiler.... They will be there to help!

We purchased a new gas boiler and a new domestic hot water tank (both Vaillant brand) from Ilmachauf. We had a number of problems during installation (non-compliant installation upon receipt of PEB, no hot water for a few days and the alarm system cable was cut). Despite all these problems, we are very satisfied with Ilmachauf’s performance. At all times, Mr. Bentahia and his team remained calm, very responsive and keen to quickly find solutions to problems. A serious and professional company that will not let you down in the event of a problem. I highly recommend them!

Quote received very quickly after the visit of the boss of Ilmachauf who came on a Sunday and a few days later, replacement of 3 boilers in our small building and lining of the chimney. Work done in a day and a half. Very good team. Very effective. I am very satisfied.

Order placed on Tuesday, boiler replaced on Friday at 2 p.m.! The boss came with three men to do most of the work, removing the old boiler which was immediately taken away by a scrap dealer. Responsive, available, fast, professional. The staff were very polite and friendly. They took away all the trash, boxes etc. and swept everything away. All this for a reasonable price, without pushing consumption by offering useless equipment like others.
I recommend them without hesitation.

Good morning,
And here is my Vaillant ECOVIT VKK 366 floor heating installation and Boiler 200L hot water production is mounted with the replacement of 11 thermostatic valves and the chimney casing, spectacularly amazing they have the equipment 15 meters high. After an initial telephone contact explaining the work to be done, I received a first estimate, the boss came on site. Creation of the quote with a quick deadline, it's ok for the quote and the day of the work, it's perfect. On the second day of work at 2:00 p.m. they evacuated your old oil boiler and what goes with it and it's great you're warm again, we'll see you again in two years for maintenance.
