Maurice provided air conditioner and heating maintenance and identified potential problems which were corrected. He was prompt and professional!“

“Needed to replace hot water heater, AC, furnace & lower air duct due to sewerage backup & flooding. Ron did a stellar job installing all HVAC & water heater; he built new lower duct from sheet metal to accommodate space allotment in furnace area of utility room. Every aspect of install was spot on. First time I have gotten a rave review from a city inspector. Highly recommend Ron of Alexander Plumbing.“

“Quick response, very knowledgeable and honest. I called yesterday (on a Saturday) with a problem and within an hour, Steven, our technician, arrived. He assessed the problem, explaining everything along the way. I believe their pricing is fair and they provide different options, when they possibly can. Highly recommend!!!“

“Great Service provider... very knowledgeable and is there when you need him. I strongly recommend signing his package monthly programs he offers. He will preseve the life of your existing hvac system.“

“Princeton fuel is one of a very few honest HVAC companies left in our area. They have been around since the 1930s and are very reliable.“

“Bart and his partner had accommodated the small task of replacing my leaking faucet in less than 24 hrs of request. It was a small task but they gave the time, expertise and even did an extra one in my bathroom when I inquired about an issue (I laughed on how I lived with it when all that needed to be done was to tighten something). This alone shows that they value every customer, no matter how small the job might be.
I very much appreciated the fast response, straight forward, fair pricing -- no nickel and diming customers. Will use them again for my plumbing needs.“

“An amazing company! They installed two systems in my house about two years ago. The team was professional, and the installation was clean. I needed service today, and although we were just 2-3 weeks out of warranty, the team came and checked the system at no charge to us. Thank you, Scott! I appreciate a company that values long-term relationships with their customers. It did not go unnoticed.“

“Eric and his team did a great job for us on a recent HVAC replacement. We got great advice throughout the project as it wasn't a cut and dry type of job. The installation team was clean, courteous, and efficient. It is clear that they know there stuff and communication was great; before, during and after the project. We have since used them for some other properties as well and they continue to deliver. Highly recommend.“

“Scott responded quickly to our air conditioner problem and had it fixed all in the same day. He worked hard to get it done and was the consummate professional throughout.“

“I want to give a huge shout out to John and Payless Plumbing! If anyone is looking for a plumber, please give them a call. John is a great person who saved my family from having an unexpected expense right before Christmas. Earlier this morning my downstairs bathroom toilet wouldn't stop running, so I shut the valve. My husband is very handy and can usually can fix almost anything, so tonight after dinner he went to look at it and noticed that the valve was leaking. He shut the water to the house and went to Home Depot to get the parts he needed to fix it, but as soon as we turned the water back on the valve blew and water was everywhere! I immediately went on to Hazlet Moms and searched for an emergency plumber. The first person I called was a local person who was very well recommended. He gave me a very good estimate over the phone, but said he couldn't come until tomorrow. Since that would leave us without water, I told him that I would call him back, and he literally hung up! My next call was to Payless Plumbing. John spoke to my husband, who explained what he had done to try to fix the problem. John asked him to send over pictures, and right away he told him that he had the wrong part. He then literally sent him a link to the correct part from Lowes ($11) and told him exactly what he needed to do to fix it and to call him back if he needed to! After a quick trip to Lowe's, my husband was able to fix the leak! John and Payless Plumbing went above and beyond. It is obvious that they are extremely honest and trustworthy. If you ever need a plumber, please call John and Payless Plumbing!“

“Rare to find, professional, genuine experts who know their trade, love working in the family business ❤️ more importantly care for the customer's needs. I had a bloody good experience with AC & Heating Experts Princeton doing right by me and aircon. I feel better now. ✌“

“Outstanding Experience – Highly Recommend!

Our neighborhood recently had some re-piping done by Aqua (our water provider), which required follow-up visits to replace individual water meters. As a result, many of us ended up working with this plumber—and every single neighbor I spoke to had a great experience, including us!

From start to finish, the communication was excellent. I got a voicemail about scheduling, and when I called back, they responded right away. I then received a text confirming the appointment, and on the day of the visit, I got a reminder along with a photo of one of the technicians so I’d know who to expect. That extra touch made me feel really comfortable.

They arrived on time, were incredibly polite and respectful, and took great care while working in our home. I work from home and they were very quiet throughout the whole visit. We have a cat, and they were super careful to keep doors shut so she didn’t sneak out or get into the basement while they worked. They didn’t move anything unnecessarily and checked in before shutting off the water to make sure I had what I needed.

They were professional, friendly, and clearly take pride in their work. I offered them drinks and use of the bathroom, and while they declined, they did so with kindness and professionalism. The entire interaction was smooth and pleasant.

Several neighbors were so impressed they asked for a business card so they could call them for future work—and honestly, same here. We worked with them for plumbing, but we’ll absolutely be calling them again for HVAC and other services in the future.

Highly recommend!“

“Fantastic service, and smooth replacement of our ancient water heater. Very friendly and they know what they’re doing!“

“Noah was great at helping us troubleshoot a water heater issue over the weekend. He came out the next day and helped resolve the issue.“

“The people who work here are amazing. I'm a new home owner and very new to DIY home projects but they took 10 minutes to walk me through what I needed to do for an issue I was having.

A part I bought didn't fit, they refunded and helped me find the right one. Just all around very helpful.

Absolutely going to these guys next time I need help with a plumbing project.“

“Our water heater broke and flooded the basement on early Sunday morning. Called them and Luciano was on emergency duty. He calmly walked me through what to do, and suggested a good local company for mitigating and drying up the flood (which should ideally be done asap to prevent mold), and scheduled a replacement for Monday. Later in Sunday afternoon, with the mitigation people already at work, the broken heater was leaking some more. It was time to call Luciano again and this time he offered to come and just replace the heater ---on a Sunday afternoon! He was so nice and helpful, and was willing to take hours off his Sunday to do so. Normally they don't do new installations on Sundays. Very pleased with Luciano's going above and beyond, and being so helpful.“

“Robert and his assistant, Josh, arrived on time and quickly took care of the plumbing issues I had. When I remembered an additional issue with a second sink, they fixed that too. Great customer service at a reasonable price.“

“I’m a happy Client.
Six Hvac did the entire heating and air conditioning system in my house, gave me an excellent price and excellent service, I love how they work. I joined the club membership that they have and for only $44 a month they change my air filters and humidifier pads, do safety inspections, check for gas and refrigerant leaks, clean the entire system avoiding deterioration, in that club they also include parts and repairs, they have 24/7 service, if you have an emergency they do everything possible to help you. The owner is a very honest person and always willing to help the client. I highly recommend Six Hvac, we have been their clients for many years and our ventilation system is excellent thanks to them. 5⭐️“

“AJ and team replaced our 18 year old HVAC system on short notice when it gave out during the record cold winter ‘26. George, Chase, and Connor knew exactly what they were doing and completed the job quickly, cleanly, and explained the new system to us. Absolute pleasure to work with!“

“These folks are amazing and this evening was the second time I've gone to them. Scheduled maintenance, then needed it sooner due to a bit of an emergency with an adjacent unit. Robert arrived within an hour of calling me back, and everything was handled professionally, calmly and quickly. Highly recommended!“

“John came out for the yearly contract and HVAC servicing, he was professional, super thorough, informative and we shared some laughs. Highly recommend!“

“Brian responded very quickly and had our furnace fixed within an hour and the furnace back on. Highly recommend this company and their wonderful techs“

“As a NJ License Real estate Agent I've been doing business with Manny for 10+ years I've never had a complaint. He's very professional and friendly as well. Keep up the good works Manny!!!“

“Very happy with my choice of Cleworth Comfort for a new HVAC System. I got quotes from four companies.

Cleworth Comfort had the most detailed proposal outlining all equipment choices with competitive pricing.
Also, happy that Ernie took the time to meet me in person and let me know about his family history in the business.

Installation was quick and professional. Cleworth Comfort also sent in the rebate information for me which saved me additional time. Very happy one month in with my decision to go with Cleworth Comfort“

“Frank & Mike are Genuine Professionals; they installed new kitchen Faucets for me, which only took 20 minutes. They come on time, did a perfect job, and were reasonably priced; I was so overjoyed and appreciated with this ABAT Plumbing.“
