Based on the age of the furnace, we knew it needed replacing. Alex replaced our furnace, oil tank and added heat pumps to keep us cool in the summer. We had a couple hiccups along the way. The true quality of a provider is how they respond to those hiccups (mfg defect and intern error.) Alex was highly accountable, responded quickly and made sure our install and ongoing service was in perfect order. Plus, ABG has a secret weapon... Krista who manages all the details is amazing. They are a dynamic duo building a high quality business that goes above and beyond. Highly recommend.

Based on their web-site ad and some reviews, I talked to this company about a maintenance-cleaning…read moreof our heat pump units. I told Bill, the office coordinator, that we have three indoor units and one outdoor unit (the condenser). He said that the total would be $385, but since I'm a new customer there would be a $100 discount, making the total $285 - his words. I agreed to these terms. At no time during our conversation was a figure of $485 uttered by him, something I would not have accepted, even with the discount. And yet, the invoice that I received two days after service completion (about 2 hours' work by one technician) asked for $485 minus the $100 discount, plus a fuel surcharge of $7.50. I called to complain that this was not the agreed-upon amount, but Bill simply denied having made that offer. But I know what I heard him clearly say. Lesson learned - never accept an unwritten quote! The work done was underwhelming - acceptable, but more or less perfunctory without much oral communication about the state of the system. I would recommend anyone needing this service to shop around and get everything in writing before agreeing to the terms. I will not be a continuing customer.

Make sure to have him explain EVERYTHING about his pricing 'flat rate for the job' or else you will be accused of not asking questions (whether you did or not). Make sure to have him discuss with you anything questionable before he makes his 'executive decision' and fixes something in a way that doesn't even make sense based upon the facts then charges you for HIS fix. Make sure to resolve any questions or concerns BEFORE paying the bill. If your husband calls him to discuss the price afterward, make sure to be on the call to dispell some of the mis-truths. When I attempted to address some questions/concerns, he admitted that he should have talked to me before making the executive decision and presented a possible fix but then didn't call me back as he said he would. I can accept that some of the issues happened because I didn't ask enough questions. He initially agreed that he should have asked first but later went back and wasn't willing to accept his piece when he spoke with my husband. Just not a good experience at all!

I called Citizen Energy and the came to my home in a very short period of time, diagnosed the problem and told me I needed a new furnace. my existing furnace was less than 5 years old and should have been under warranty. They ordered a new unit and installed it, also within a very short time period. The employees were polite courteous and completed the job in a short period of time. I paid the invoice and thought everything would be fine, Hoping they would do something proactively to help with my warranty claim since only a licensed hvac tech can initiate this. Well, that was one year ago and I never received any reimbursement. A couple weeks after the furnace was installed. I had a problem that the furnace would not turn on. Despite repeated calls and voicemails left with this as well as speaking with the owner, they never returned my calls did they ever provide . I ended up calling another company to come and determine what the cause of the issue was. It turns out that there was a blown fuse on the circuit board. To continue the story this past winter after the first really cold I discovered that the propane portion of the furnace was never working. It was never as a result I was only using the heat pump and my bill high. Once again, I called energy several times and left the situation. I never received a return call and I ultimately never received any . As a result, I had to call another HVAC company to come in to determine what the problem was. They discovered that it was a simple switch that was not set correctly. However, I was charged $600 for this discovery. Had citizen energy done their job correctly. None of happened. In summary, I would tell any customers who energy buyer beware. At first, it may seem like they are very efficient and are very interested in serving you well as a .
