We are so happy with Allegro. We moved into a newly built home. The vacuum system was improperly installed and damaged due to a renovation. We had three quotes and the other companies were either hesitant to try to fix it or could not figure out how. Nora was very understanding of our situation and did her best to help us out. She sent a senior technician to the house. He figured things out and got our system working at a fraction of the cost of the other quotes to replace the system. The customer service has been fantastic. I have no hesitation in suggesting Allegro!
