Reviews of local pros in Hewitt, New Jersey

Quick service, great price, honest advice. Steve was an informative straight-shooter. He repaired a mini split in no time at all. Would use them again in a heartbeat.

Fixed my heating quickly and fairly priced. Was honest and up front about what i need and dont need fixed

Had an incredible experience using J+S Heating.
Lost heat on a Friday night with -4 degrees temps.
Spoke with owners directly and made an appointment for the following morning.
Steve was excellent.
He was able to troubleshoot & evaluate the system.
Steve was able to get the system running again temporarily until repair parts could be procured Monday.
J+S was was quick to respond, professional and overall a pleasure to work with.

I highly recommend J+S Heating & Cooling.

J&S has been at my house a few times for different hvac repsirs. Always Quick professional service. I would highly recommend.

I have had j&s come and service our heating and air-conditioning. I could not be happier with their services. They truly are a full service, honest, reliable, knowledgeable and professional. company. I highly recommend them

Steve was great. Very informative, knowledgeable and timely.
I had an excellent experience with J&S heating and colling. Steve was extremely professional from start to finish - on time, neat, and a great communicator. What really stood out was his honesty and transparency about my situation. He took the time to educate me on how to recognize when expensive refrigerant or other repairs aren't actually needed, which is something I truly appreciated after being burned by other companies in the past.

It’s clear that Steve values long-term relationships and word of mouth to promote his business because he leads with honesty above all else. That kind of integrity is rare, and it gives me confidence to continue working with J&S in the future.

A special shout-out to Jenn in the office, she was incredibly accommodating with my billing needs and made the process smooth and stress-free. I would recommend them for anyone looking for professional, trustworthy HVAC services!

Very knowledgeable and polite.Steve is very helpful and you can ask any question and helpful.
They respond to our request fast.they save us cause the 1st company that came to us is not good. This J and S company is dependable and my whole family is very much contented with their job.

J&S Heating was very attentive, professional and proficient in the yearly maintenance of my boiler. I will absolutely use them in the future and highly recommend their service.

They were very prompt with our emergency situation. They got us up and running with heat quickly. They were very nice and did a great job. I'd recommend their service.

This company was a god send when I first called them for help and I have used them ever since. They took the time to truly diagnose and fix my furnace issues and ever since it has been smooth sailing. Highly recommend them for any HVAC work you may need

Thank you for a great professional experience. Quick reliable and professional. Steve knows his business and took the time to explain the work prior to getting started. Would absolutely recommend them and have them come back if we needed any future HVAC related work

Very disappointing experience

Steve came to repair my heat pump and spent a long time assembling and disassembling a perfectly working thermostat. He said he would order a new thermostat and install it for an extra charge “to troubleshoot.” He left without identifying the actual problem but still charged me $150.

I called another HVAC company the same day — they located and fixed the issue in just 10 minutes for half the price.

Unfortunately, this experience showed a lack of competence and professionalism. I strongly recommend looking elsewhere for HVAC service and not relying on those perfect 5-star reviews.

I had a very positive experience with J&S and they are an extremely good company to deal with. Tech team is highly knowledgeable. Back office was great at communicating and keeping us informed of every step. They operate with a lot of integrity and transparency which is rare these days in this field. Highly recommended and will definitely give you guys a call for future heating cooling issues! Thank you

Jennifer & Steve (J&S) are very professional, knowledgeable, and friendly. They checked and inspected our home heating system very accurately and quickly. They also educated us how to control and troubleshoot our heating system in the future. We are very satisfied with their thorough services and highly recommend them.

J&S Heating and Cooling company. Save the day. On October 12, 2025, I arrived back from vacation and my heating system was malfunctioning. On 10/13/25, I called J&S and they came out the same day and fixed my heating system. With the change of seasons it’s important before the winter season kicks in that my heating system was working properly. Last year we installed a battery operated nest that was not responding to my app
J&S located the problem right away and switched us to a traditional Honeywell thermostat
And just like that we have heat again.
Thanks
