I was promised a $100 gift card when I switched over. They are Not the cheapest supplier, but the…read more$100 over 12 months covered the difference with $50 left over. Yay me. When I tried to collect the card I was told I had to be a customer for 6 months. Wasn't mentioned up front, but no biggie. Now after 6+ months, I once again tried too get the gift card. I filled out the form and jumped through the hoops... Today I received an e-mail saying my payments were "not on time" as required for the rebate. I have Auto Pay. I have never missed a payment. My payments are Never Late. This is B.S. Find someone else... anyone else.

Think Energy uses sketchy and fraudulent practices to acquire customers for their service. A rep…read morecame to my door impersonating an Eversource employee asking to do a quick check on usage, he then told me for my trouble I would be receiving a 20% discount on my bill he just said someone would call me to confirm. I received a call with from a rep using misleading tactics to get me to agree to switch my service to Think Energy. I told him about the door rep claiming to be Eversource and how unethical this was and told him I would not be moving my service. 1 week later I received a letter in the mail from Think Energy thanking me for switching my service and stating that they had notified my old provider of the change. I not once granted permission for this and specifically said I do not want their service but they went ahead and switched it anyway. Do not use this company, and be wary of door to door representatives.

Great service - twice…read more I recently bought a home with oil heat, and being my first experience with oil heat, I know nothing about maintenance or even who to call. So I did some research, called a few companies, and picked Prendergast to do a oil burner tuneup because of their reasonable price. The guy came within a week and being a techie guy I want to know how things work so I hung around with the technician and had him explain everything he was doing. He was very courteous and informative and even gave me helpful tips on keeping it running well. A month later our hot water tank sprung a leak and it had to be replaced (~15 years old). I called a number of companies for quotes and Prendergast was the only one to ask me enough questions to give me a serious quote and two options. I ended up choosing the more expensive but much more energy efficient option. Anyhow, I found out later that the state of Massachusetts has a energy efficiency rebate program that would get me $300 back, so I emailed the link to the company and asked for their help. In a few days, I got a letter in the mail with the rebate form all filled out, and a copy of the invoice for proof of purchase. I got my rebate back today (took the state 6 weeks to process it) and just want to share the quality of the customer care I received. Tom, the company owner, was a great help all the way and always responded to phone calls and emails within a day.

Tom Prendergast and Brendan and their team are examples of experts who are knowledgeable and take…read morepride in doing truly excellent work for a fair price. Over the last 15 years, they have replaced our boiler (in the depth of winter) and then as our piping needed upkeep and improvement, they've come back reliably even when they're under great pressure. We will sorely miss them now that they've retired. They deserve a rest and I hope they can relax and enjoy retirement. Thanks Tom, Brendan, and team!!
