Issler GmbH

Great team, very good customer service, good internal organization

Mr. Rieger has already been with us a few times, we were very satisfied with his services.
We would be very happy if Mr. Rieger would continue to be available to us.

We intended to replace our old oil heating system with a Solvis solar system with Luna evacuated tube collectors and gas burner and quickly received an on-site appointment from Mr. Brunner. The offer also came very quickly. After we had decided in favor of Issler, we were able to apply for the subsidy together with Mr. Brunner. The offer was valid until the funding approval. On 02.11.2020, after Mr. Burkart went through everything with us again on site due to Mr. Brunner's inability to attend, the order was placed and execution began on 23.11.2020. Already on 26.11. the heating went back into operation. Mr. Mehlin and Mr. Werner with a trainee carried out the work very cleanly and conscientiously. After only 5 days everything was ready. Mr. Brunner was present on the construction site once a day.
We were very satisfied with the friendliness and the execution and can recommend Issler with a clear conscience.

The heating change was fast, clean, competent and not overpriced. The employees are friendly and work precisely. Issler also took over the coordination for chimney sweep and electrician and the application for government grants at BAFA. The Solvis heating system is easy to retrofit or add solar and photovoltaic at any time. During construction we were supplied with heat and hot water by separate heating generators. Many thanks to all.

It's just fun to work with you, the whole package just fits.
Looking forward to more projects together.

We purchased a Solvis heating system from Issler. From the consultation, to support, to the installation, everything went great. It was important that the planned system meets our current and future needs. Planned time frames were adhered to and the old system including peripherals was disposed of.

The work lasted a week and the mechanics present worked very cleanly and were also available for questions. The comprehensive briefing on the new equipment was very pleasant. Our wishes regarding the settings were always implemented and explained. Even for subsequent questions, they still had an open ear.

It was particularly pleasant that we did not have to worry about anything. All service providers such as electricians, energy suppliers and insulators were coordinated and commissioned by Issler.

On a positive note, enough time was always scheduled for discussions and all concerns could be clarified without time pressure.

The whole thing happened two months ago and we are still satisfied. Based on this experience, I can only recommend Issler in the area of heating construction.

Excellent execution by Mr. Obermonteur Mehlin with the help of his very motivated and precise working trainee.
Appreciative and friendly way of dealing with the trainee, very polite and careful behavior with us as customers. Tip-top in terms of punctuality and cleanliness, as well as expertise, advice and support from the entire Issler team.
We did not have to do without hot water and heating during the installation: Issler provided us with a mobile hot water system and fan heater to tide us over.
Advice and help in applying for state subsidies was part of the excellently organized overall package. Wellness package for wellness heating, showering and living!
Thank you!!!

Excellent, transparent advice, planning and timely installation. Pleasant cooperation during the week-long work.

Our old heater suddenly went out in October. A solution had to be found quickly, as we were approaching the cold season. Since we have been customers of Issler for many years, we asked them about it. We were very satisfied with the quick feedback on planning, offer and implementation. Mr. Brunner, our contact person, was a great help in the decisions and also with other questions. The nice team of fitters installed everything competently and left the "construction site" totally clean. Keep it up!

We were very satisfied with the planning and execution of the heating installation, well organized, timely and expeditiously implemented. The installers were very concerned about cleanliness during their work to minimize the impact on daily life in the house. The advice on the various funding options (BaFa, etc.) was also very good, everything worked as planned. Many thanks again to Mr. Burkart, Mr. Brunner and the installation team of Issler.

Dedicated staff, reliable.good advice,

The invoice is repeatedly issued as a total amount, i.e. the individual services, in particular the hourly rate for the fitter and the individual costs of the numerous spare parts, are initially NOT comprehensible. Provided then - on explicit desire - nevertheless a listing of the individual invoice positions took place, one must determine if necessary that one for simple sanitary work a "proud" mechanic hourly rate (inclusive VAT) of nearly 90, - € !!!!! set and initially for the individual parts the multiple of the competition (Bauhaus prices; inclusive VAT) amounted to. The Issler range was from > 320 % to > 540 % of these comparison prices !!!! After written intervention about these horrendous prices, the amounts were generously reduced to > 210 % to > 360 % of the competition. Such a "billing practice" I have not experienced in the past 30 years from any other craft business. In my opinion, this is out of the question.

As always super personal, authentic care!

Very nice team

The replacement of an oil heating system with a gas heating system in 2019 was highly professional from the initial consultation through to planning and implementation. All employees involved showed a high level of personal commitment and showed no signs of fatigue, even though the project dragged on much longer than foreseeable due to external circumstances (gas supplier, Grenzach municipality).
A big thank you to the entire team!

We have replaced our old oil heating with a gas heating Solvis Ben (Brunswick). We chose the all-round carefree package (disposal of the old system, applications from the chimney sweep, gas works, ED, BAFA, etc.), and our consultant, Mr. Brunner, did a great job. Also the installation of the new system under the direction of Mr. Mehlin
has worked very well. In any case, we were completely satisfied from the consultation to the implementation.

Your service staff is competent, very friendly and enjoyable!
It has never happened to me that I was asked over the phone if you could come a little earlier than the time
could come a little earlier than planned. Mostly you sit as a customer and wait for the craftsmen, who then come much later.
come much later. This is very annoying and time-consuming! It can happen that the craftsman is also
craftsman is overloaded, but an orientation phone would be and is then very useful!
As you note, I am a "fan "of your company and will certainly recommend you.

With our order from the Issler company, we ordered the all-round carefree package. From clarifications with the chimney sweep, to energy consultants to building authority clarifications, everything was taken over by Mr. Brunner. We were extremely satisfied with the advice, as well as with the explanations on display models at your site in Grenzach. The commissioning and handover of the heating system by Mr. Mehlin was also very exemplary.
Very young, committed team - keep it up!

Great team! Great performance! Thanks for the good service!
