What Our Customers Say
"We had a new gas-fired boiler installed and we couldn’t be happier with the service. All the staff is very knowledgeable, more than willing to answer your questions, and really help you make the right decision. Install crew was friendly and really cared to get the job done right. I appreciate them going above and beyond and walking me through all the details along the way. Highly recommended."
- Chris N.
"Arrived at my home with a water heater disaster and the gas company pinning my gas services after a decision to change the meter despite an appointment set for this week. The technician was AMAZING - found all of the issues and resolved them- including guiding me to call the gas company to have them come and unlock my gas flow. No hot water, no heat turned into a great day two with everything working! On time, talented, and caring!!!"
- Lynn H.
"My repair crew of 2 arrived on time. Both had smiles on their faces & greeted me by name—so impressive! It made my day. They went to work & had my boiler part installation completed in a reasonable amount of time. These two men are stellar employees & I hope I have the good fortune to see them again if I need service in the future."
- Di D.
"Thank you again to Riedell. I couldn’t be happier with their work. We have had everything from initial construction to new faucets from them and couldn’t be more satisfied. Clean, communicative, and efficient. They are always a pleasure to work with."
