Best in New York NY

I called this business and left a message with their service on Sunday, it is now Wednesday afternoon and they have not even called me back.  So I  would not recommend them.
* Update due to the owner's reply below, perhaps his voice mail message should have stated that he was on vacation.  I am writing a review based on my experience, as is my right.

Love them they saved us so much money all others said we needed a new water unit they fixed it! We have been using them ever since!

Came right away, fixed the clogged drain, reasonably priced.  I would highly recommend Darwin and his helper.

Mike came over on short notice to fix a leak underneath my kitchen sink.  He followed up with me about my time slot and gave me an update when he was running late. Friendly and provided an excellent job and explained what was causing the leak. Affordable and well worth the price I paid! Job was done and he also cleaned up after himself, which is a major plus!

Picked Adam off his reviews on yelp and his quick turnaround. My fiancé and I just moved into our home and HVAC stopped working. Called Adam and he responded right away. He showed up 3 times in 4 days and was responsive each time. Unfortunately the sellers never disclosed the HVAC  system has a huge leak so it will need to be replaced. Adam however worked with us and found a solution to get through to next spring, which is a huge help.

His partner company was also responsive, helpful and great to work with. Will be using them going forward for and future issues/maintenance. Highly recommend.

He's very responsive, a life saver when the kitchen sink was clogged. Very reasonably priced, get the job done.

I cannot recommend Justin and JCA Mechanical enough. He was so knowledgable and calm in the face of my late-night plumming emergency panic. He was efficient and got the job done in no time. We asked him to (what seemed like the impossible to me) fix a 35 year old toilet and he handled it like it was nothing. He was also safe, respectful, and reliable in the times of COVID here in NYC. I recommend his services to all my loved ones and will be directly calling only him from now on for any plumbing fixes.

I had a problem with my boiler towards the end of last winter. It was freezing outside and we were cold. The boiler wouldn't start. I cleaned it, vacuumed the combustion chamber, did a couple blowdowns. The water was crystal clear. It would run for a little while and then shut down again, in the middle of the night for example. When we woke up the house was as cold as an Ice Age cave. I called this plumber, he came with his son and they replaced a couple of gadgets without looking at it too much. Just like that the problem went away. Did not ask me for appointment fee, the price was very reasonable. He told me that part of my heating system was done by someone who was not a professional. I have both steam and hot water heat for different parts of the house, the hot water heat part having been added much later and the job was not quite done the right way. The plumber recommended a solution and did the job quickly and for a reasonable price. He explained what had to be done and I could tell he knew what he was talking about, even though I'm not a plumber. Everything is looking good so far and I'm ready for the next winter.

Reasonably priced and do a great job. They have done plumbing work for us for years and put in a water heater. Jim even helped my 92 year old grandfather when he stuck on the side of the road.

I called this plumber to service our furnace for the winter from an internet reference and was glad I did. Not only did the technician routinely service our gas boiler, but found a pet that needed replacement and then thoroughly cleaned the unit. As a resultt, our heating system works like a charm.

My neighbor -- who is a tough grader of service providers -- recommended Ajax to me to help with a water pressure problem in our shower.  I called Adam and he suggested checking the shower head before paying us a visit.  That took care of the issue.  So, without even coming to  the house he fixed the problem for me, no charge.  How's that for fantastic service!  Adam was also super responsive.  I couldn't recommend anyone more highly.

I called Zatos plumbing for the local law 152 gas inspection. They were quick to respond they did it on the same day and had it filed the following day. Highly recommend them.

Skilled professional with great communication and responsiveness. Actually did more work than necessary, replacing old parts to make sure the job was done right without any extra charge. You can see he cares a lot and takes pride in his work! EXCELLENT!!!!!!

They wouldn't give me a quote on the phone after my sink pipe exploded. They only gave it after they finished and they charged me almost a thousand dollars for 2 hours of work. I was happy with the 1st time I called them but now they are really expensive and the guy took forever to finish the job. Next time I'll call a local plumber.

I called in because the boiler stopped working on one of the coldest nights of the season.   Sylvester and Joe D are excellent at what they do.  Both techs showed up rather quickly.  Sylvester diagnosed the problem and Joe D did a great job with installing a new part for the ignitor/spark function of the boiler.  He was clean and efficient.   He put all his efforts in yet he completed his job effortlessly.  As a customer for over 30 years (had an oil burner now it's gas),  we have experienced our ups and downs with the company,  however, when it comes to boiler service they do not disappoint.

Thanks for having talented people on board.
