We were impressed by the results of LSTS — it was a clean and precise installation. There was no mess, no unnecessary machinery that would add extra costs. What you see in the drawings and documents is exactly what you get in the final result. Moreover, it's a year-round solution, and it can be executed both in winter and summer. The warranty period passed smoothly. The team performed excellently, checking both in winter and summer. We got great results with heating, ventilation, and lighting. The lighting is well thought out, and everything from lamps to windows is great. Very good result overall.
