Review Date: 10/06/2013 | Author: Sakena P., Jamaica, NY

Comments: Time management was excellent from receiving a quick response of my inquiry to coming out and fixing my unit. The team was professional, respectful of my time and went a step further to provide valuable advice on keeping a well maintained unit.

Comments: Our newly bought townhouse in Flushing did not generate hot water although the boiler was working. I found J&J Mechanical Services through Home Advisor and asked them to check the option of adding a water heater. They quickly identified the problem: the cold water bypassed the boiler. They fixed our problem and suggested that all we need was to give the boiler a clean up. We are very happy with their service. They are honest, capable and very friendly. I highly recommend J&J Mechanical Services.

Comments: The guys were fantastic, they stayed late, beyond what I imagine is the end of their normal work day and worked outdoors on top of the building in dark and rain to fix my AC! Thanks so much :)

Comments: They did just enough work to get me taken care of and didn't charge me more than what was reasonable.

Review Date: 02/26/2013 | Author: Miriam R., Brooklyn, NY

Comments: These guys are great - I called them in the morning and within two and a half hours the repair person arrived and within 45 minutes the problem was resolved. The necessary part was replaced in my boiler, he repaired a leaking valve without my prompting and he was very professional throughout the visit. My boiler is back up and running again - I will definitely use them for future jobs.

Review Date: 01/01/2011 | Author: John J., Brooklyn, NY

Comments: J&J Mechanical Services, Inc. provided a service provider by the name of Sam. He was there the same afternoon I called to check out the problem. He then provided a temporary repair as he had to order the part. He was back at 5:00 PM the following day and completed the work. I was very, very satisfied with his work and would recommend anyone to use this heating and plumbing service provider. I could not be more happy. John Johnson

Review Date: 09/29/2010 | Author: a Neighbor, Brooklyn, NY

Comments: Sam came to check and clean my 2 hot air furnaces and hot water heater. He checked them out, cleaned them where necessary and declared them in good shape, charging me one-half of his phone estimate because he wasn't here that long. I thought that evidenced honesty and integrity--qualities in short supply these days among contractors.

Review Date: 09/22/2010 | Author: a Neighbor, East Elmhurst, NY

Comments: They arrived on time for the initial estimate, and for the subsequent flushing and cleaning of the heating system. They walked the 3 floors to make sure heat was coming in on ALL the vents. They are courteous and professional. I recommend their services.

Comments: Very pleased with this Service. Sam was excellent - extremely professional, polite and helpful. We have a 23 year old split level A/C system so this was not the easiest of jobs! However, Sam did his best to improve the cooling of the unit and it is now working very well! I strongly recommend J &J!
