"Your technicians were very professional and extremely kind." Everything is working perfectly again
"By this email I would like to express my content about your technician’s intervention today at my house. He made a very good impression on me. He worked decently, with great care and order and obviously knew what he was doing. Moreover he paid attention to safety (fire extinguisher within reach) and was very kind." Today’s service – impeccable!
Thank you for your quick and effective intervention." .Repair of my heat pump.
"Since the reparation, the heating in my wife’s office works perfectly. I reported this problem earlier to the firm that installed the system, but they only replied that I had to adjust the air-valves. I tried that and even opened the entire circuit but nothing changed. We feared we would have to buy an extra heating unit, but one intervention of your technician was enough to make everything work perfectly again. The heating is now even better balanced in the other rooms as well! And our hot water problems are solved too! Thanks again for that. I forwarded your details to my neighbours who are experiencing the same problems as us and are looking for a real specialist. Thanks again!" A big thank you to your employee for the repair of my heat pump and boiler
