"My experience with Roto Rooter was first rate. I posted my problem on HomeAdvisor and they contacted me promptly and gave me a couple options - repair or replacement of my water heater. I chose to replace it and Jim was able to locate a good replacement for me and get me scheduled the next day. The Plumbers arrived promptly and had my water heater replaced in about an hour. Even cleaned up well. Thanks Roto-Rooter."

"Very prompt to respond, show up, submit quote and finish job. They also installed a new water heater. Very friendly and professional. Saved us money by using existing switches! Wonderful to work with and would definitely hire again and tell neighbors and friends to."

"First, this company has handled all of my heating needs/problems since 1986 when they replaced a 58 year old gravity furnace with a high efficiency forced air system. I was not always pleased with this first furnace, but the company techs always gave me good service and advice. I needed to replace this furnace due to a flooded basement that left the unit under water for 6 hours and it was 23 years old. I looked to Home Energy Center (HEC) because of the good service they had provided over the years, but it was their job to lose - I had some questions about the old furnace. I called to make an appointment for an estimate and Kevin came out on the date and time of my choosing (at that time as late as 7pm and Sat. available). Kevin knew about my old furnace and told me they had stopped installing that model a few years after my purchase - they had found something better (I believe mine was an early high efficiency model -92%), I was impressed that he didn't try to sidestep any of my criticisms and presented me with what I thought was a good heating plant. Kevin said it's normally a 2 week wait for the installation but they had a cancellation the following Monday (4 days) and if I opted for that date they would deduct $250. He already had my business so I thought this was a nice gesture. That Monday the 2 installers came at 7am sharp and got right on the job. They said it would take about 8 hours so when I came home at 330pm I was surprised to find they had finished up and left They did leave all the manuals and instructions for operation. HEC provides what they call a "happiness check" where a company rep makes a return visit to check out and familiarize the homeowner with the system. I called Joyce and set up this appointment for a week later and Steve arrived at the appointed time. He had a checklist of items to go through with me and answered all my questions. He again covered all the warranty information and said I would receive materials in the mail to apply for an energy rebate and the Federal Energy Tax Credit (2010 exp). I did get these documents as promised along with excellent instructions in dealing with them (thanks Joyce). Granted I have only had this furnace for 2 months but so far I have no complaints and the house is warm. I would certainly use HEC again and will for future service/maintenance calls."

"We recently built a new home and Bedwell Builders did the plumbing, heating, A/C and electrical. Great group of guys to work with and their work was exceptional! Would highly recommend them to anyone."
