The people at Gelok replaced the natural gas boiler in our recently purchased 1990s house, installed a heat pump, made a Perilex connection in the kitchen, installed solar panels, and converted the ventilation system to humidity-controlled mechanical ventilation. We chose Gelok because we like to support local businesses and the previous homeowner already had a maintenance subscription with Gelok. The site survey for the quote yielded smart solutions, such as running pipes indoors through an existing duct. The quote was detailed, and questions regarding it were answered well. Unfortunately, there was a significant delay between the order and the execution, but that seems to be the case across the industry. We were delighted with the execution. Pleasant people working in our home, and the work is done neatly: dust is vacuumed up and mess is taken away. And the end result is impressive. Sleek, neat, and professional. They also quickly helped us think through and resolved a suspected malfunction. So, we can be brief about our experience: top-notch!
