Gas Heating and Furnace Service
Overpriced and incompetent. JN Service has worked on my house 5+ times in the last month, totaling nearly $10k, and every visit created a new problem that cost more to fix. Most recently, they came for a small leak and left after cutting/breaking multiple pipes, leaving my entire home with no running water?despite assuring me I?d have at least cold water. They then returned only with an expensive full-home repipe quote, refusing to even quote a local repair. I?ve since had three other plumbing companies inspect everything; all agreed that JN?s technical decisions were poor, their repipe quote was severely overpriced, and their quote structure (initially with almost no detail) was concerning at best, predatory at worst. I will never use JN Service again and strongly recommend others avoid them.

I recently had trouble with my thermostat on my HVAC. Despite it being a very warm summer JN services was able to fit me in on the same day and stayed for as long as it took to get my HVAC running. Their staff is very friendly and knowledgeable. They kept me informed the entire time. I would highly recommend them.

We’re very happy with Junior & his team’s HVAC work. We had some issues with our HVAC system. He showed up on time, worked with us on the cost and schedule and got the job done timely. We found his crew to be very professional and helpful. Definitely recommend him for any plumbing and HVAC work.
