On 11/6/2025 Danielle Sands had this to say:
D&M did an amazing job upgrading our furnace in our old farmhouse. Other companies shyed away from repairs and never followed through with estimates to replace it. We are very happy after they installed our new furnace today. Their technicians were professional and courteous. Highly recommend!
