Showed up fast and was very clear with what the issues were and how much the repairs would cost. Ordered all the parts and had it fixed the next morning.

Our central air conditioning installation was especially challenging. Duckyâ s had to be installed in 5 locations. Cutting walls apart then repairing them. Neil was there every day working on it. He and his crew cleaned and vacumed after each days work. I would recommend them for any central air conditioning installation

NJM Mechanical just completed the project of replacing my gas fired boiler. From the first meeting with Neil, while I was still soliciting quotes, I felt he was different than others. He was not in hurry to sell me something. He took his time to assess the situation and provide his quote. He also came across as a very honest individual; an observation I experienced first hand by the time he completed the installation of the new boiler, based on how he kept me updated throughout the project. He clearly has an extensive knowledge of the heating systems. He took his time to make sure the work was completed properly and spent two days on a job that was scheduled for one day. Although the delay was due to faulty parts, not once did he complain. He was graceful throughout and kept me updated of every development. He was thorough and his attention to detail was unparalleled; and he left the work site sparkling clean at the end of his work. Cleaner than he found it. Extremely pleased with Neil and NJM mechanical; I highly recommend him.

Expert service for a job of great difficulty. Old pipes and NJM had to work in very cramped conditions. Neil and his staff worked tirelessly until the job was done. Great service and value and couldnâ t be happier with the finished product.
