    Everything was done in an efficient and timely manner

    5.0 James O. Monroe Township, NJ

    Outstanding service. We came home from a weekend away to a pool of water from a broken water heater. We were having trouble getting it replace due to a holiday and some other issues. The owners called me after hours and had their installers at my home the next morning with a replacement. They also offered to help me with flood remediation. The guys who installed it were awesome, fixing what needed to be fixed and cleaned up the mess left from the old heater. All for a truly reasonable price. Highly recommend all of them.

    5.0 Tom L. Tinton Falls, NJ

    Very easy to discuss all the issues with Dawn. She was extremely friendly and understanding and patient with all the questions we had prior to scheduling the installation.

    5.0 Manoj S. Parsippany, NJ

    What I liked that prompted the 5* rating. (a) Prompt and direct response. To the original proposal, as well as any subsequent communication/messaging. (b) Direct, consistent and "suspiciously" low pricing. The price quoted was less than 50% of my regular HVAC company. To be fair my regular company is one of the most expensive. GSWH quote was barely higher than the heater's price on Supply House. Had it not been for rating here, I would have avoided this company on that suspicion. Especially since it was a Text-only quote. No contract write-ups with details. Now I can say they seem to have achieved this competitive pricing through focus (water heaters only), volume and efficient operations. Kudos to GSWH for making this possible. (c) My purchase qualified for utility company rebate. I was not aware, neither was this mentioned during sales pitch. But along with Township paper work, GSWH sent me information about where/how to apply for it. That's a bonus (d) I spent additional money on extra work identified during install. But it all looked logical to me and could not have been part of the original quote. (valve replacement, etc.). (e) Chris and Roger worked efficiently and very respectfully. My job had some challenges (non standard sizing of the original unit's pipes, older unit wont drain easily, etc.). I suspect they spent more time than typical for these situations. But there was no complaint or ask for any adjustments. Of course not everything was smooth. But nothing to take away from overall good project and hence 5 star rating. Rough bumps on the execution were: (a) GSWH filled in City form and mailed me. After that, it was my responsibility to see it through with the city. My previous (expensive) HVAC contractor handled all those directly. I chalk it to remaining operationally efficient and focused. I had not trouble working through city process. (b) There was air left in the boiler side plumbing. This caused my boiler to stop functioning on the night of the install. There was hot water (because of the storage tank) but the heat was lost. I contacted GSWH at 9 PM, and they sent Chris and Roger back the next day. That day they did a thorough (once-bitten-twice-shy like) job of removing air from the system. They insisted and exchanged the expansion tank on that system too. I agree it was truly required. The system worked smoothly since. (d) Chris indicated that I may need an expansion tank on my heater per city code. Since my old one did not have it, I said may-be not. I wish he had insisted with confidence. Because city inspector did insist on it. So I had to call them to do that part later. At a higher fee of course. (e) The aesthetics could be better? I am no plumber, so I don't know what is better plumbing functionally. But arrangement of pipes and the expansion tank could be more compact? It definitely looks tidy. But looks less efficient use of space. (f) The call on the night of the install, for reporting problem with air in the system, was responded by a less polite person than my generation is used to. But nothing to take away from effectively scheduling and addressing it.

    5.0 Jason T. Belleville, NJ

    This was by far the friendliest group I interacted with. They were nice from beginning to finish, didn't try to upsell me constantly and showed up exactly when they said they would show up. I would highly recommend.

    5.0 Brandy D. Montclair, NJ

    A massive thanks to Carmine and his son for installing a new water heater on Christmas Eve (and on a Sunday to boot). His prices were nearly half what another company had wanted to charge us the night before, and the other company did not even look at the water heater. Carmine and his son were incredibly responsive, professional, and fast. We will definitely use their services again. We are super grateful that he answered the phone at 8 p.m. on a Saturday night and was here by 9:00 a.m. Sunday morning.

    this is how a job is supposed to be done.

    4.0 Thiru S. Edison, NJ

    office personnel were a little curt while answering follow up questions. the field/installing staff were very courteous and professional

    5.0 Gary J. Monroe, NJ

    They beat everyone's price showed up on time put down drop cloths to protect rugs and did good work and completed the work on time.

    4.0 Daniel R. Morganville, NJ

    Totally satsified except for a couple of up charges which I did not expect but was told about prior to the work getting done. In addition to water heater being replaced was told that my hot and cold water valves needed to be replaced along with my chimney vent which I was told, would not pass code even though it did 4 years ago when the town inspector looked at it. Added another $400 to the bill but overall still reasonable - Dan (Marlboro)
