They got the water flowing again, but could not fix the cause of the problem at that point. I now have hired them to finish the job. Very knowledgeable about wells and water systems."

Both times, they were able to schedule me right away, which I really appreciated. The team was professional, efficient, and made sure everything was done correctly. Their customer service was great from start to finish, and they made the whole process smooth and stress-free. I highly recommend them for any plumbing needs!"

"Dakota came out a couple of weeks ago and checked out my electrical panel and quoted me the cost of a few projects. Today he came and installed three new outside outlets. I was impressed with his knowledge on the first visit and very impressed with his skills and the quality of his work today. He is a very approachable young man and was able to answer all of my questions. This is a 45 year old home and he gave me confidence that the electrical system is up to standards. I have used Hart for plumbing and electrical for almost a decade in my previous home, and started using them for hvac as soon as they expanded into that business.

"My elderly mother is partially blind and disabled. On November 1, 2021 her washing machine broke leaking water in her home. In desperation she called rotor rooter. Roto rooter came out, stopped the leak, and put dryers in and left. They returned a few days later to remove the dryers. The technician quoted my mother a cost of about $3000.00. My mother signed a contract but could not see what she was signing. After Roto rooter Reno removed the dryers they sent a bill to my mother for $9000.00. The contract she signed stated Roto rooter would remove walls, roofing, insulation, baseboard, tile etc. Roto rooter didn’t do any of those things. Roto rooter is price gauging and took advantage of an elderly disabled woman. Roto rooter technicians were in the home no more than 3 hours total. First my mother did not have capacity to enter into a contract as she couldn’t see what she was signing. 2 Roto rooters technicians told her the cost would be about $3000.00. 3 Roto rooter did not do the work in the contract. I believe Roto rooter is commuting elder abuse and fraud."

"In 2020 Eco Electric installed a Whole House Fan in our home. It has worked well for us and helps cool our home in the summer. Recently it stopped working. I called Eco and they sent Kyle out to diagnose our problem. Kyle was able to quickly isolate the problem to wiring in a recently installed smoke detector. He was able to fix the matter and get us back up and running. I do recommend Eco."
