We had a 13 year old gas fireplace insert system and it was starting to have multiple problems and issues, so we asked SUNDANCE Energy Services Inc. to go ahead and install a new one for us, with a bit of an upgrade. They were very nice people, and they did a good job for us. They have been doing annual service on the old unit, so they knew what we needed. I recommended them to my daughter who bought two systems from them herself. They are a good company, and I highly recommend them! They are a very professional company!
