"Duane was great. He came out and figured out the problem with my heating system (noisy and shaking). He fixed the issue for a very reasonable fee and explained his other products and services without being the least bit pushy. Would recommend their services."

"When I first wrote the below review in the Spring of 2017, I had not yet actually hired Extreme Plumbing. Here is what I wrote about them then: A gentleman did come out to give me an estimate on a major plumbing issue I'm having and to consult with me on upgrading the rest of my duplex. Let me just say, that of ALL the contractors, repair people, etc. that I have consulted with, few have delivered on their promise--no, the expectation--to get back to me with an estimate IN WRITING. Within a couple of days, I received a professional estimate via email. It's a small thing, but it speaks volumes to me about how this company handles business. They take it seriously. I've had folks come out and they're telling me all the work that needs doing and I'm the one taking all the notes! Then I never hear from them again! That's not a consultation. Extreme plumbing was different. He was professional and friendly. He spent time walking through with me and seemed to genuinely care about helping me. When I told him the water bill was high and we noticed a small drip in the tub in the vacant unit, he shut if off. Small things, I know, but he didn't make me feel like I was putting him out by asking for a bid. I even tried to offer him my credit card to take a small fee for his time and he would not accept it. He was happy to do what it took to try to get my business. Ultimately, I will use Extreme Plumbing once I've vacated the house later this spring. To Extreme Plumbing: Please keep treating your business and your customers in this manner and with this amount of follow-up, honesty and integrity. When word gets around, as I'm sure it will, you will dominate the Philadelphia plumbing game. Fast forward to November 2017 and my first opportunity to use Extreme Plumbing's services. Tenant was complaining of not having any heat. Wayne, the owner, was immediately responsive. He went out to the house and serviced the boiler and charged an extremely reasonable price which I thought was well worth the convenience of saving me the headache of going out to the house. He's honest, he's good, he's licensed, he's professional and he's a great guy. From now going forward I will also be calling him for referrals of other reputable contractors for non-plumbing and heating related odd jobs too!"

"After receiving news from the contractor sent out by our home warranty that our boiler was officially irreparable, we started doing some research for repair companies and found New Energy Solutions. Without any heat during freezing temperatures, Erik made sure to send his foreman (Buddy) out to take a look and get us an estimate that same afternoon. We were impressed with the willingness to walk us through the installation process and the cordiality of both Erik and Buddy. The work was done efficiently and they even stayed for a while to ensure that every aspect of the new system was running properly and to walk us through the various aspects of the new boiler. I would highly recommend New Energy Solutions to anyone looking for a friendly, local, and reasonably-priced HVAC business. A great experience from start to finish."

"Sergii was able to fit us in his schedule in the midst of a severe heat wave. He and his team worked expeditiously and were able at install a new air conditioning system as well as align the existing furnace with the new system the same day. The air conditioning system is working fabulously well and I have no complaints. Will definitely recommend him for the services he provides in the HVAC world."

"Great company. I had my AC fixed. Their staff, from April who handles admin, to Wayne who diagnosed our machine and found the leak for the cost of the initial visit whereas other companies wanting to charge us a $1000 to do that. To Thomas, who did a professional job, making sure I was informed of the process, answering any questions I had, and taking care of any concerns. He was professional and very personable. I can't say how much they cost compared to other contractors but right off the bat they saved me $1000 which puts them far ahead of the crowd in my book. Even if it was a bit of a premium, its a premium I am happy to pay for good craftsmanship and piece of mind."

"They were polite, and friendly. They installed an all new heating and airconditioning system, ran ductwork for our basement and installed a new hot water heater. They were here for 2 days, and they did a great job. We will be calling them to look at some electrical work we need fixed."

"Pat gave me a great deal on a high performance boiler as a replacement for my 20 plus year old boiler. He installed the boiler and an indirect water heating system in the summer and he had to follow up in the fall to make sure the heater worked correctly. He did that and was very responsive to my questions while at my home and over the phone later. Pat was very professional and knowledgeable and I would use him him again and recommend him to others. Bottom line - Pat did what he said he would do!"
