Neukom Marzolo AG — Gewerbestrasse 13, 8197 Rafz, Switzerland

This time I was completely satisfied: all the room thermostats were fully open, yet the flow measurements were at zero and the floors were cold. A pump had failed—an emergency at this time of year, on a Friday before a weekend. The heating project manager, the lead technician, came, saw, and conquered! From the first phone call to the repair, it took less than six hours.

Unfortunately, I cannot recommend this company. Their work ethic left much to be desired. Agreements were not honored. For five years, I have been dealing with the same problem – water remains in the toilet bowl and doesn't drain. This problem occurs regularly, and a solution has yet to be found. What was particularly disappointing was that the managing director did not respond to any attempts to contact them, neither by phone nor email. Overall, a very unprofessional impression.

Replacing the heat pump in a single-family home – a truly successful project From the initial problem analysis to commissioning, the entire project ran smoothly and to our complete satisfaction. The project manager impressed us with his excellent support, transparent communication, and professional expertise. The contracted specialists also worked efficiently, meticulously, and always respectfully – both amongst themselves and with us as the customers. From the customer's perspective, this project was executed perfectly in every respect. Many thanks to everyone involved!

We replaced the old gas heating system in an eight-family residential building with a heat pump with a nominal thermal output of 44.4 kW. It draws its energy from the ground via four 250 m long boreholes. The scheduling and collaboration with the client worked perfectly from planning to completion. All tradespeople involved were friendly and courteous in every respect. All services and documents required by the contract, as well as the administrative work with the Canton of Zurich for the subsidy fees, were provided. I highly recommend Neukom Marzolo AG for this or similar projects!

We had our central electric storage heating system replaced with an air-to-water heat pump. Beforehand, I obtained seven quotes from heating contractors, including both large companies and local businesses. Samuel Kuhn and his company impressed us on all levels, while the other companies were very noncommittal. The planning and consultation with Mr. Kuhn were very structured and easy to understand. The administrative effort amounted to just a few signatures. Personal requests were accommodated without any problems. What was agreed upon was carried out reliably. The product is tailor-made for our needs. Mr. Kuhn clearly explained what made sense and what would save us money. The first quarterly bill, received throughout the winter, confirms this. The on-site technicians were also very friendly and courteous, and enthusiastically answered any questions that arose. We chose Neukom in advance because a foundation of trust was quickly established and because everything we wanted was simple and achievable, rather than difficult and expensive. This approach has proven successful, and we are simply satisfied customers. Thank you!

Highly recommended company! The challenging project of replacing our decentralized electric storage heating system (without a heat distribution system) with an air-to-water heat pump was perfectly planned and executed with great expertise. Everything went smoothly from start to finish in a consistently friendly atmosphere. The system has proven itself very well so far.
