"Robert Johnson was so helpful in discussing the h/w heater installing and the venting requirements. His price was so much better than others companies in the area. His crew for the actual install was as also great! Kevin, the crew leader, explained how everything works and the cleanup was perfect!"

"arrived on time, and repaired water heater quickly."

"I highly recommend Justin from County Line Plumbing and Heating. He recently replaced a hot water heater at a rental property I manage and did a fantastic job from start to finish. He’s prompt, reliable, and always responsive—especially during emergencies. His customer service is excellent, communication is clear, and the work is done right the first time. A true professional and someone I trust with my properties and my own home."

"I couldn't recommend Brad more. He is very professional and courteous and does fair and honest work. After being without hot water for nearly 2 weeks and getting nothing but ridiculously overpriced quotes from all of the major local companies, when they bothered to return our calls, we were beyond frustrated. Thank goodness for Brad. He offered a reasonable quote and completed the work in a very timely fashion. He was reliable and personable and also returns phone calls quickly. Brad went above and beyond and was very knowledgeable. My family appreciated his work and we would absolutely call him again without a doubt. Our sincerest thanks to you Brad!"

"I posted an urgent plumbing job on Angi and heard from a couple of pros within about an hour. Andy from AS Plumbing & Heating was the first to give me an estimated arrival time and asked for photos beforehand so he could better understand the issue. He arrived exactly when he said he would, quickly identified the problem, explained everything clearly, and completed the repair efficiently. He was friendly, professional, and kind throughout the visit. His estimate was reasonable, and he even reduced the final cost as a thoughtful gesture. I wouldn’t hesitate to recommend AS Plumbing & Heating and will definitely contact them again for future plumbing work."

"Derek was prompt with his reply, clear in his communication and clean/efficient with his work. I would recommend Derek and his team for any future plumbing needs."

"Professional, friendly. Did the job and showed photos of the resulting flushed out debris from our on-demand water heater."

"I was impressed with his knowledge and his ability to explain his thoughts to me as we were reviewing what needed to be done to install a replacement propane water heater He scheduled the project right away and came in the time frame designated, finish the work and also did extra functions that had to be done to allow the equipment to get into my basement. He followed up to make sure everything was working well and offered to come back in a day or two if I needed assistance. His billing was easy and professional. We are hoping to have him back again next year to do some HVAC work."

"Everything went wonderfully with this company.  They were very professional, listened to exactly what my problem was, and explained to me how they were going to diagnose the problem and/or solve it before doing any actual work.  Once they started, the team (three people came) worked together like a well-oiled machine.  One was in the room with diagnostics, one was at the fuse box looking for possible problems there, and the third went into the crawlspace beneath our house to look at the physical wiring.  Once the problem was found (there was a faulty wire beneath the house that had come loose from the junction box), it was fixed and tested within minutes and another full diagnostic was done to make sure there were no other possible issues.  They cleaned up after themselves very neatly.  They also replaced the light switch with a dimmer switch at no extra cost!  Well within my budget, and came in even lower than their original (FREE) estimate!  I would highly recommend this company to anyone in the Bergen County area.

"Furnace job:
Allen replaced our ancient Utica Boiler with a new and efficient Buderus., as well as updating all the supporting hardware He did a fantastic job. He came in, assessed the work, made some recommendations (such as installing individual zone pumps), issued an estimate on how long it would take him and how much it would cost. Allen came in and performed all the work he specified in the time he said for the cost he said. Very positive experience.
On the shower and toilets, again, Allen did exactly what he said he would do. We didn't get an estimate for this work so I can's say how well he did coming in on budget, but he did perform the work in the exact amount of time he said he would.
