A very satisfied customer – for years! We've been customers of GST Van Paassen for decades now, and for good reason. Our experiences have always been positive – whether it was air conditioning installation, boiler installation and maintenance, roof leak repair, or bathroom leak repair. They're easily accessible, keep their appointments, and offer helpful advice. The work is always carried out neatly and professionally. The installers work cleanly and leave everything neat and tidy. The quality is high, and the staff is knowledgeable, friendly, and reliable. In short: a professional and dedicated company that we've trusted for years. Highly recommended!

GST is a fantastic company! I called this morning with a problem, and around noon they were at my door to fix it. It wasn't an emergency at all, but they still responded quickly, a company that truly cares about its customers. Where else can you find such a company?

Last winter, we bought a complete Honeywell system with adjustable zones. To this day, it's NOT working properly. After several attempts to contact them with insufficient knowledge of the correct installation method, they've now gone completely silent. Perhaps we're complaining too much these days. This has resulted in incorrect calibration and noisy circulation pumps. Many promises, accompanied by unprofessional attitudes and communication. We hope things will work out, but that seems more and more like a delay in disappointment.
