Reviews and Ratings for Heating and Air Conditioning Services

I’ve been a customer of J&J for years. They have not lost the value of customer service, being on time and professional. They’ve always explained all options and helped me make the best decisions. This company is managed how I wish all others would be.

J&J Mechanical replaced my entire furnace and AC systems with brand new efficient models. The owner John was very responsive in providing an on-site evaluation and follow-up quote. He clearly explained all of the different options/pricing and did so in a straightforward way. I felt extremely comfortable using J&J Mechanical for this project especially with their competitive pricing and positive planning experience. The team showed up early, worked diligently throughout the entire day and only departed when the work was finished later that night. They were polite, knowledgeable and hardworking and left my house as clean as before they arrived. Finally, John continued to follow-up afterwards to ensure everything was functioning properly. I highly recommend J&J Mechanical for any HVAC needs as a result of my experience.

Phenomenal service all around. Immediate response, out for service the next day. Tech answered all my questions and offered advice in several areas. Only fixed what was needed and did not push additional work. Would hire again. A+.

I highly recommend J&J Mechanical. John was great to work with. We were having issues with our AC and needed it replaced. We called J&J and John came out to give us an estimate, He was on time & professional. He answered all of our questions and got the quote to us in less then a day. The weekend came and my husband had a few questions and John was more then happy to answer them even though it was a Sunday! He made the whole process stress free. The day came to install our new AC and we even received a text to say our technician was on their way. Chris, Evan and Simon did the install. They were professional and did wonderful work. They put out tarps and left NO mess. My shrubs weren’t even damaged outside and I didn’t have to cleanup after them inside either. Chris was the best! He answered all of our questions and explained what he was installing, why our old unit was failing etc. The quality of his workmanship is top notch. The guys worked efficiently and by the afternoon we had the new AC installed and a cool house. I am very happy with J&J and I highly recommend them!

Evan was very knowledgeable and responsive to my needs and questions. Very glad I found a hometown service I can rely on in the future. I am confident in calling J&J back in the future, and even now with any follow-up questions on the visit just completed, which is a major plus.

The most professional and honest company. I highly recommend them to everyone.

Overdue review here. I have been using J&J since moving to New Jersey in July 2022. They have serviced my HVAC and furnace and recently installed a whole house generator. Every time they are professional, on time and do great work. Their communication is top notch. I have a service contract with them and will continue to work with them for all my heating, cooling and generator needs.

Went thru heaven and hell to make sure we had hot water as soon as possible.

J&J always provides excellent service. Techs are very courteous and do super clean work, recommend them for anything HVAC related.

Excellent service and great technicians and office staff, will not use any other company for my heating, cooling, or plumbing needs.

Stayed with company after initial installation of up and downstair units. Consistent good follow-up and service at a reasonable price. Friedly staff. Highly recommend.

Great price, amazing service, delightful customer service and top notch products. If you don’t use at least get a quote from J&J you are doing yourself a disservice!

They did a great and very efficient job!

I love J&J! Professional, friendly, responsive and knowledgeable!! Top notch. Highly recommend. 👍

Always does a phenomenal job!

Excellent service.

Amazing and trustworthy place to use, quick with response time and reasonably priced as well! Highly recommend John and his team for all your HVAC needs!!

We have been customers of J&J Mechanical for years. Every job ever done by them has been done by professional and knowledgeable technicians. Evan came for a service call. Along with being knowledgeable and professional, he explained every aspect of the problem with clarity.

Our AC will be serviced and a new furnace installed in a timely fashion.

Along with the quality work that is always done, we know we can trust this business for their integrity. Thank you for your service.

John and Hunter arrived on-time. They were extremely professional and took their time checking the A/C unit to ensure nothing was missed. Everything was fixed quickly, and I was cooling down in my house by afternoon. I’ll be using J&J in the future, for all my HVAC needs.

Great company came out on a weekend.

An amazing company to work with! Met with multiple employees and the owner John as well due to unforeseen issues. Everyone was professional, compassionate, and honest. My gut told me to go with J&J and I’m so glad I did! Highly recommend.

J&J has replaced our furnace and AC unit. When calling, they were able to schedule us by the best day and diagnose issues on the spot. They explain everything to you and present different options as well. They were able to return and replace the units within 2 days of the initial service calls. When we needed our furnace replaced they dropped of space heaters and then window units for our AC which is great considering we have small children and infants. They are nice, respectful, courteous, and professional.

Scott was very professional and explained everything he did. Always a great experience.

Excellent service. Friendly technicians. Highly recommend.

Oil to gas conversion. Installation was awesome! Technicians were extremely professional and courteous. The quality of the install was impeccable!

I was so happy I used J&J. The Service Rep was very knowledgeable and easy to work with. I would never use anyone else for now on.

J&J Mechanical is always on time, has very reasonable prices, and polite honest employees. They also donate to the local schools. I would highly recommend them!

Great company to work with!

Always a great experience for my wife and I. They have excellent costumer service! We have used them for both replacing our AC unit and furnace now. They were very timely, and came to get our new furnace installed within 12 hours of it breaking overnight. We won’t use anyone else!

Every time I call, I get great customer service. Greatly appreciate all the help and service. Love this company and recommend them to everyone.

I can’t recommend John and his team more. We ran into a ton of unforeseen issues due to poor planning from our contractor and John rearranged his schedule for us multiple times in his busiest season. Don’t know what we would have done without John’s patience and expertise. Will definitely use again in the future!

The technicians were on time, clean, professional and explained everything they were going to do to complete the project.

John and his guys were a real pleasure to work with. They replaced my entire HVAC equipment (furnace, hot water heater, a/c unit, humidifier). The job was done within a couple of days and although there were a few things that required return visits, the guys came back and resolved the issues quickly and with great attitudes. Shout out to Nicole as well, she was great to work with too. I would highly recommend J&J to anyone looking to upgrade their HVAC system.

J&J is professional, responsive, and reliable. I would never choose anyone else!

Hunter came out to repair and service our oil heater. He did a fantastic job! Highly recommended!!

Put in a service call at 10:00am, 10:15 appointment scheduled, 1:00pm technician arrived, 1:30pm issue resolved. Enough said. Thanks John for exceptional customer service!

Update: The same happened again. Called John at 12:0pm, Hunter came at 1:20pm and heat was up and running by 2:30pm. Best in business.

The gentleman was very polite and professional. Informed me of what the stats were and what’s good and bad. Highly recommend!

I can’t speak highly enough of my experience with J&J, from John going out of his way to coordinate an appointment while he was away on vacation, to how great Hunter and Evan were when they came out to help us out with our oil furnace. They bent over backwards to sort out the problem and were more than patient in explaining things to first-time home owners. Highly recommended.

Best HVAC company out there. Great customer service, knowledgeable, and professional. We will continue to use them.

My furnace started making a rattling noise right before a cold snap was about to hit. I called J&J Mechanical to see if I could schedule a service visit. Nicole is very nice and got me scheduled for first thing the next morning. Evan did the service for my furnace. He was professional and identified/fixed the problem quickly. I have a maintenance agreement with J&J so I have used them for tune ups in the past. This was my first service visit and I was extremely satisfied. Thank you Evan and J&J Mechanical!

Very pleased. J & J was very responsive. Hunter the mechanic was great. Very knowledgeable, respectful and kind. I highly recommend this company.

Nicole had me set up with in 1 hr. Evan was quick and knowledgeable. We were able to fix the problem with in the hour without being gouged with price. Thank you

Just had J&J Mechanical here for our winter maintenance on our heating system – they call when they’re on their way, always on time, respectful of our home, clean up when finished and have always done a great job! You won’t be disappointed if you use J&J Mechanical!!

Tankless water heater service was second to none. Evan and Mike were clean and thorough.

The J&J Mechanical technicians were very professional and thorough. We’ve been using J&J Mechanical for several years for our furnace and air conditioning maintenance and have always had a very good experience.

Absolutely love the quality customer service and the staff that work at J&J. It’s refreshing to have a company show up when they say they will, everyone is friendly and professional. I will always recommend this company to my neighbors.

I don’t let anyone else touch my mechanicals. J&J have been terrific. I have used them for 14 years and won’t use anyone else. They are the only ones I trust and recommend.

J & J Came out to replace my split unit and had it done in a day. They were very professional competitively priced, very nice, and considerate of my home. highly recommend them. And my HVAC company now…

They did a great and very efficient job!

Always there when u need them. Professional, courteous staff.
