Lena J.Lena J. ★★★★★ I have a 99 year old home that has never had central AC before. The staff at Thomas Hoffmann took the time to walk me through what would be needed and where it would go when they provided me with a bid. I ended up going with them for the AC install as well as replacing my broken furnace. Danielle in the office was very responsive to all of my phone calls and answering all of my questions and very easy to schedule with. The staff who came out for the install could not have been more courteous and professional, the arrived when they were supposed to, they sent messages when they were on their way, and the completed all necessary work promptly. They then patiently walked me through pairing the new smart thermostat they installed and showed me how to use the app. They tested all of the systems and equipment before leaving and it has been working beautifully every since.
