When I noticed that I had an issue with my central heating, this company was the only one saying honestly that it would take at least 3 weeks with the workload they had at the moment, but that they could help me by giving proper advice and the needed materials for a good price. In the end I was able to fix my central heating problem myself using their expert guidance.

I just had someone come by for a quote for a hybrid heat pump with a boiler, two air conditioners, and a bathroom. The gentleman indicated that creating quotes is a lot of work, and he especially doesn't want to write quotes that include options that might not be chosen. It shouldn't take too much time, let alone effort. Apparently, there are wheelbarrows full of money lying around, because our budget of around €30,000 isn't worth the effort of preparing a decent quote. He also told me that a heat pump isn't a good idea if you use less than 2500-3000 m³ of gas. A frankly ridiculous story/attitude.

I'm incredibly happy with the service from Haarman Installation Technology! The leak was expertly located and repaired, and the repairs to the toilet floor were neatly completed. They installed a beautiful, new, modern toilet, and everything was cleaned up neatly afterward. Kudos to the staff—they're fantastic!
