DJH Mechanical Services Inc.

I can’t say enough good things about DJH Mechanical Services! From the very beginning, they’ve been professional, knowledgeable, and truly committed to quality work. They installed my central air units and have been maintaining them ever since, and everything has been running flawlessly. A special shoutout to Nicholas, our technician — he is absolutely fantastic. Incredibly courteous, detail-oriented, and always willing to explain what he's doing in a way that's easy to understand. It’s rare to find a tech who combines expert-level skill with such a friendly and professional attitude. He treats your home like it’s his own, and that really sets him apart. The company itself is also a pleasure to work with — appointments are easy to schedule, they show up on time, and they do the job right

BRONX, NY - When the summer heat was brutal and my A/C gave out in my Bronx apartment, DJH Mechanical came through like absolute pros. Nick showed up fast, handled everything with skill, and made sure I was back to cool comfort in no time. You could tell he knew his stuff and genuinely cared. The whole experience— from the first call to the final fix — was smooth, reliable, and fully professional. If you need HVAC help, these guys are the real deal. DJH Mechanical earned my trust, and I’ll be calling them again without hesitation.

As a business owner, I truly value professionalism, reliability, and expertise — DJH Mechanical Services Inc. delivers all of that and more. Their team is knowledgeable, responsive, and committed to getting the job done right the first time. Excellent service from start to finish — highly recommend!"

DJH Mechanical Services is an outstanding company with highly skilled professionals who truly understand HVAC systems. Dennis, a knowledgeable mechanical engineer, goes above and beyond by taking the time to explain how our equipment works and how to use it efficiently. He is the backbone of DJH Mechanical, and his expertise inspires confidence. I highly recommend DJH Mechanical for anyone seeking reliable HVAC service.

We spent almost $ 1,900.00 (the price for a new condenser)for less than 10 days of comfort. The main problem wasn’t solved and they want to charge us again to come back to fix the same issue. It took them 10 days after our complaint to quote a price for a new system. Our friend talked to them on our behalf and they said they will come by to fix it but instead of doing that they offered to reduce the labor for the new system. They never quoted a price before working on the problem, so beware, we lost trust with the company
