"I’d definitely recommend this gentleman to anyone looking for a good, reliable plumber. He did some plumbing work at my house and ran into a few problems that needed some thinking outside the box. He was able to come up with solutions instead of just telling me it couldn’t be done. He showed up when he said he would, did a great job, and made sure everything was working properly before he left. I’d 100% recommend him and will definitely be calling him again whenever I need plumbing work done."

"We had a Burnham boiler that developed a crack (apparently they are notorious for doing so). It was spewing water all over our basement every time it turned on. Mike came over promptly and assessed the situation, giving us several options. We could have gone with a less expensive boiler, but chose a higher efficiency one as well as a new hot water tank (since ours was about 14 years old) and new connections. The installation took all day and into the evening with Mike and his partner working virtually non-stop. He also vacuumed up five gallons of water from our basement. We felt Mike was very professional as well as pleasant and honest to deal with. The new furnace has been in for a few days and is very quiet. He has estimated a savings of about $900 a year in oil costs with the new system.

"I could not be more pleased with this company or this service. I found them here on AL and with a rebate, it was a great deal. When I called, the woman who answered was extremely polite and helpful and took the time to go over the entire audit process with me (she wasn't rushed as some receptionists are). They sent an email to confirm the date and time.
When the team arrived, they were on time and each of them introduced themselves by name to me before coming into my house. They were all very polite and courteous. The leader (I can't remember his name) gave me an overview of the process and explained things as they went. Basically, they simulate high winds around the house and then monitor for where leaks are. My house is relatively new and has no basement, so it was already pretty efficient, but there were some major leaks by the front door and attic door, which they sealed on the spot. They also showed me that I could hold my hand over any electrical socket, even ones on interior walls, and feel the "wind"--which means air was leaking out those! So I plugged them all with those little socket protectors. The guys also took me into the attic and showed me some leaks, and fixed them--and fixed the attic door by adding a little latch to help it stay closed. All in all, they reduced the amount of air getting into my house by 500 (I forget the units). It was clear they didn't just make up this number--they showed me the number after the first test and then after the second test (when they had treated the problem areas).
I also got a few free CFLs and LEDs, and bought 3 more LEDs since they were at a great price. They left some rebates with me, although all my appliances are new so I didn't need anything. 
When they left, they each said goodbye and were very professional until the end. They were respectful in my home and asked before opening any closets or doors, etc. I felt very safe with them here, which is not always the case when people are in your home working. I think the price is a fantastic one, especially with the AL rebate that was on when I scheduled. I feel I got my money's worth. My husband and I had tried to plug some leaks ourselves, but we didn't really know what we were doing and we had no way to measure if we were really helping anything. This audit gave me hard numbers to look at and I was impressed that they did the fixes on-site (included in the price--for instance, they plugged a whole around my front door frame by installing a clear plastic barrier). It was a great deal and a great experience. Highly recommend!
Bonus--when we resell this house in a few years, I will definitely list that we got a professional energy audit performed on it and that it's very efficient. Definitely a selling point!

"Because the first tech was not truthful and initially spoke in a condescending  manner to me I wanted to write Petro Corp. I was informed by someone at Petro that the field supv and the supv who initially denied my request for a third Petro tech who NEVER send my complaints to upper management The two different Petro front line supv, in my experiences ,clearly demonstrated ANTI-customer behavior If I had not been an aggressive customer I would not have gotten the third Petro opinion even though I pay the for a service contract I feel that if I am paying for services that Petro needs to deliver service without the mess that Petro put me through. Upper management needs to have a way for customers to contact them (I also went online and could not get that info) I am amazes that no one I spoke with at PETRO knew who their CEO was One woman gave me a bogus telephone number I feel that with Petro's consumption of the Propane companies had made them so large that they must feel that they have NO ACCOUNTABILITY to their customers. They need to improve their record-keeping...they claimed that they did not have certain records about my boiler that they installed. I feel that was a smoke-screen to relieve themselves of responsibility for my boiler And their customer service field supv need to be retrained or removed. No customer should have to go through what I have had to deal with since March 2016 Lastly,  documents that the first tech gave me to sign was checked as though he was dealing with the exterior oil tank, which was NOT the case. He also knocked over our telephone pole that we installed as a protective barrier..there is no way that he did not know what he did because I pointed out the fact that he needed to be careful backing out. Yet, he drove off without informing us. He obviously has a serious credibility problem because he was the same tech would saud we need a new boiler"
