Buyer beware! I can…read morenow understand why this company has numerous 5-star reviews. Initially, I had given it a 1-star rating (if I could give zero, I would). However, I was advised to remove my initial review or our project would not be completed. On Father's Day morning, we called this company for an emergency due to issues with our boilers. Initially, we were impressed by their prompt response and diagnostic services. However, working with David and his company turned out to be the worst experience we could have had. David promised us a new HVAC system (water heater and heat pump) within a day or two. This has now turned into three weeks. The communication between us and David was terrible, and he even threatened us. To make matters worse, he left our family in the middle of a heatwave, with a newborn baby! David has said vile things to my family because we asked questions about the work that was supposed to be completed and complained that the service we paid for was not complete. He was angry that we filed a complaint with the financial institution we worked with to get the work done he removed the breaker from the heat pump system and told us that "our children will suffer tonight" ( heat wave in affect and it's over 100 degrees in the home ). His words were so disturbing that they are not allowed anywhere near our property. They also damaged and left a hole in our ceiling. After stating that someone would come to fix it, just like they usually do, no one came, and they didn't even bother to follow up. We had to pay someone else to come and fix it. We took out a loan for a specific system and he promised us that system, yet installed a cheaper lesser system with equally bad customer service. Once the job was reluctantly "finished," our heat pump didn't work, and we had to call in and pay other companies to not only evaluate the work this company did but also fix it. We later found out that the work they did could have resulted in a fire if we had kept the unit running. Not only are they dishonest and take advantage of emergency situations, but they also do horrible work.

In which i knew I had to find a technician to come and advised what was the reason for it. Leor was able to give me an appointment right away and once here he was able to address all the concerns I had. If it wasn't for his expertise I would have never known my kids and I were breathing filty air since I had no filter in the AC unit in which caused the Coal area to be full of dirt. I would recommend his business to anyone looking for a reliable, educated and knowledgeable Tech. Now and days everyone is just trying to look where to take more money from and here it wasnt the case! 100% highly recommend anyone looking to get a great well job done!

My experience with NSJR has been simply great…read more I had a leaky hot water coil in my boiler and Sam came out to take a look at the issue. I opted to install a water heater and he detailed exactly how the process would go. At some point I changed my mind about what model I wanted and just before work started I was concerned about how a tube would be routed, but he resolved both concerns and price did not change. Day of install went exactly as planned. Unit worked perfectly and was able to use the hot water halfway through the job. Job site was left as clean as the work itself. See pictures below. 10/10 experience.

Simone personally visited my Manhattan Co-Op apartment and offered the perfect solution for a new HVAC split-duct system. I find him and his entire staff very knowledgeable, professional and ready to help. The administrative staff helmed by Rosette Lauro is the best.

If you have any HVAC needs, do not hesitate to call Arnica. They will take very good care of you !!

About a month ago I had a leaky bathtub faucet. The leak which started as a drip ended up in a…read moresteady stream of water. I didn't have a plumber on hand so I turned to yelp for assistance. I contacted a couple of them. One plumber came out looked at it and didn't know where to shut the water off at. He then never came back. I contacted Maximo and immediately got a response as well as quick quote. Guillermo came ready with everything (even the replacement hardware), looked at it and began the work. He kept me informed every step of the way about what they were doing. They came at 2 and finished about 5ish. We had previously agreed about a price. Yet I gave him a bit more because he also changed my bathroom sink faucet which the handle was broken.. the next day when I had a small issue, he came back quickly and fixed it. All in all, I probably would use him again.
