Kook & Son Inc

We’ve used Kook and Son exclusively over close to 15 years in multiple residences because of their professionalism, promptness and the quality of their work. The technicians are also trained in current equipment (tankless water heaters, high efficiency furnaces, etc)

In our most recent engagement our tankless hot water heater developed a leak overnight. I called Kook around 9 am and they were able to get someone there that morning even though the techs were already at another job (great in and of itself!). The technician then worked with the manufacturer to troubleshoot and determined that the unit needed to be replaced and was under warranty.

This is where Kook really shined: the manufacturer needed to review pictures of the unit, where the leak was, etc. before approving the claim and allowing us to get a replacement unit so there was no way to schedule an appointment with Kook since we didn’t know specifically when we’d get that info from the manufacturer. Kook worked with us over the two days it took getting the manufacturer the info they needed and made technicians available the minute I was emailed the return authorization. They arrived within a couple of hours with the replacement unit (again, without a previously made appointment), replaced the defective unit and had hot water up and running again in a few hours. Howard Kook, the owner, also called me personally several times to let me know they were on the case, working with their staffing to ensure someone would be available when needed, etc. since he understood that being without hot water, even briefly, is a big problem and he didn’t want us to worry that we weren’t being attended to in the background even as we waited for the return authorization to take the next step.

We have and continue to give Kook and Son our highest recommendation.

Howard and his team did a great job installing a full split ductless AC system in my 5th floor condo building in downtown Jersey City.

Three air handlers and one exterior wall mount units, Mitsubishi hyper heat and AC system.

They are a diamond dealer as well.

I am quite particular about analyzing cost and doing my due diligence. Spent a lot of time asking questions and Howard was able to be patient and addressed them all.

It was a complicated install, but Howard and his team took their time to plan out precisely where the units would go.

Regardless of the challenges encountered; they were able to work through all of them.

This was an expensive job, but totally worth it..

Props to Howard and his team getting the install done properly.

We bought an old home and Kook & Son have been here to help from the start. Howard kindly visited our property personally to put together a proposal for the HVAC. Askash, the plumber was great. He was both knowledgeable and patient fixing and explaining about our radiator heating. I have to also mention Diane who is the executive assistant. She is so professional and efficient on getting the help I need. I'm so happy I found this company!

I am very disappointed in this company. Obviously I am not the only one since they only received 2.8 stars out of 5. Barely over 50%. I had two appointments with them and they cancelled both times. The appointments were 5 days apart. They certainly had time to fit me in. The excuses were that there is a heatwave and therefore a lot of people want their AC fixed (DUH, why do they think I was calling?) and secondly they said it was the hours I keep at my office and these hours were not convenient for them. So basically it was my fault. I told the fool I was speaking with to forget it and called someone else. Within 50 minutes a very reliable and intelligent man from Ideal Climate HVAC was at my office fixing the problem. I now have a new AC man who I will refer all my patients to. Very poor business Kook and Son.

Unprofessional. Don't waste your time.

I called several times over the course of a few weeks to no avail. Finally, I got through to the owner who made up various excuses for not getting back to me. He then came on location and assessed the job - HVAC installation. He was rather arrogant but nonetheless promised to give me a quote for the job and, of course, he never did. I followed up three times and was ghosted.

Total waste of time and energy. Why work with people like that?

Kook & Son installed a new AC/heat pump system into a home that is way over 100 years old. At all times everyone from Kook was professional, courteous and thorough. They completed the substantial amount of install work in consecutive days, without interruption. Even prior to our purchase decision, Howard Kook gave us extensive advice and presented solutions that were realistic, reasonable and without apparent bias. The installers, Pierre and Manny, listened to me, addressed my concerns, and came up with solutions that worked for all parties involved. I feel that Kook & Son did the project right.

My go to plumber in Jersey City. Prompt and professional.

After making a service appointment a week in advance and taking a day off from work I had the pleasure via Kook and Son of being stood up. After waiting till noon I called to check on the arrival time only to be told same amazing Emercency had happen and the entire company was needed to help make repairs. After rushing to check local and national news to maybe hear of a heat issue in a childrens hospital or maybe the White house there was nothing, then I checked to see if my money was still green. How unprofessional can you be to not atleast call and inform me of the EMERCENCY call that crippled the company and blew me off. . It will be a cold day in hell before I give these people any of my money thanks for nothing.

Other reviews here have noted that they charge a little bit more compared to other plumbers/HVAC companies. The thing is, it's totally worth it. These guys know what they're doing and they won't cut corners. You get what you pay for.

*Update after having our AC units worked on again. Our system had a leak in it, and the work to fix things just wasn't as good as when I originally have these guys a 5 star review. Things were misdiagnosed. The work this time around just wasn't worth the premium they were charging. Downgrade to 3 stars.

Fantastic experience with Kook & Son! Howard Kook visited my place personally to assess a broken water heater and within half an hour his crew showed up with a replacement and installed it. Anthony and Akash were a crack team, expertly re-piping the system to accommodate the new water heater, circulator, and mixing valve.
Equally important to me though, as a single mom with a 7th grade son, having total strangers inside my apartment often makes me a little nervous- especially total male strangers. The two plumbers Mr. Kook sent, Akash and Anthony, were both dreams! I instantly felt that I was in good hands and, moreover, I felt safe.
This may mean nothing to some reading this review, but I've had other encounters with men technicians who would make offhand remarks, let a hand stray, etc... all of which I would deflect. As some readers may relate to, this is not fun.
Having Anthony and Akash on the job, however, was fun. Anthony was easy-going, relaxed, personable, put me at ease, and was very funny. Akash was a perfect sidekick, the classic steady mellow dude. What a terrific team!
PS. And they didn't make or leave a mess!

Howard and his team really offered us a white-glove experience in a challenging time. While they were not the cheapest quote we received to repair our water heater, they seemed the most experienced, knowledgeable and professional of the bunch. The team was on time, clean and professional while my wife and I had to work from home during the replacement.

When it was about time to replace a pair of water booster pumps in our 12-unit condominium building I selected Kook & Son among three different vendors I had invited to provide a quote for the contemplated work because I thought that Kook's offer was not necessarily the cheapest but the best value for what we expected. The installation turned out to exceed my expectations both in terms of quality of labor and improvement to our building. Howard, the owner, was involved along the way and I appreciated that he took time to address my initial questions and concerns on the phone and also via email throughout the process. I picked Kook & Son then also for the installation of a natural gas line to feed our barbecue grills on our roof deck. That work was completed equally well. I would pick Kook & Son again for all other plumbing or gas work in our building.

Highly recommend! In June 2021, I needed to replace my combi tankless water heater in a somewhat ‘tough to reach’ location in my home. Kook and Son provided a quote and had the most knowledge and care in assessing the situation for me, so they felt trustworthy from the start. They weren’t my least expensive quote but quality/trust that it would get done right the first time was most important. I had found out about this company through a friend who is a real estate agent in Hoboken - so again, this recommendation helped build trust early on. Howard was also very helpful and accommodating as I got the town permits for the project. The communication throughout the project was top notch. The team who replaced my unit were friendly and professional. Overall, very happy with my experience and would refer them without hesitation to a friend.

Kook & Sons were prompt, efficient, and the repairs are solid. While a little expensive, I'm willing to pay it for quality work. The plumber was also good about explaining the issue and showing me the problem, which is important to me when choosing a plumber.

Excellent service and quality work. Rushed out in the midst of the heat wave to fix my broken HVAC system after another company failed to deliver.

Tried to scam me for $700 for a/c capacitor, should be renamed to Crook & Sons

I have worked with Kook and Sons for about 5 years now. They are a cut above the rest. Howard and his crew did a superb job of diagnosing the cause of a leak in my second floor bathroom. Other plumbers were never able to diagnose the problem which was identified correctly by Howard as being caused by a faulty floor pan, which was installed by another plumber 10 years earlier, to fix the problem necessitated a complete shower renovation with a new floor pan.

The guys came did the demo work neatly and even saved some of the old tiles to repair another area in the Bathroom. My new shower looks fantastic and no more leaks, for the first time in years!

Howard is a true gentleman who knows his craft, his people are excellent, his pricing is reasonable, and the workmanship is great.

I have since called on Kook and Sons for many more projects from sink repairs, to heating malfunctions. Kook and Son's should be your first call every time.

I have been living in Jersey City for 24 years and I have used many other plumbers before Kook and Son, to say Howard's company is one of the best plumbing contractors in Jersey City is exemplified by the fact that they have been in business for decades, they are professional, and prompt, and once they have fixed a problem it stays fixed.

Plumbing may not be glamorous but when you have no heat, or leaking pipes you come to appreciate the value that Kook and Son's brings.

I have used this company several times over the years. I agree with the other reviewer about their services being pricey, but they respond quickly and do their work correctly, using good materials. Once, I had to call them to re-do a job my neighborhood handyman (read: inexpensive) did poorly. You pay for you get.

Kook and Sons charge WAY too much for basic plumbing. I previously bought into their service agreement which tbh is just not worth it. They send out two guys in two trucks to do the job one guy can simply do, and they charge you double. I also had both guys leave while on the job to purchase basic supplies all plumbers should have on their truck, time in which I had to pay for. I have to acknowledge the workers themselves were very nice people, but I cannot accept businesses that price gouge.

Had to get inch and a half blk pipe removed (about 4ft in length). Old pipe had to be cut in half and 2 new pieces with a union had to be installed.i supplied those pieces. A tee and an elbow had to be replaced. Job took under 1 hr and was charged $895. I paid it but WILL NEVER use look and son again

I am very dissatisfied with this service. I am a manager for a Dr's Office and had called this company for services. My first experience I left a message and nobody got back to me. Second time I called again and left a message, I received a response within 48 hours and booked an appointment. The plumber did not show up on the appointment date. He came the following week without notice. The issue was the toilet was not flushing, he changed the flusher free of charge which did not need to be changed. He then left and didn't come back. The toilet then overflowed the following day. I called again and made another appointment being nothing was resolved. Nobody showed up for the appointment so I called to see what happened they explained they were delayed and could be here an hour after my call. I had explained when making the appointment that we see patients in the office and the time frame was from 9-2 for the plumber to come, nobody called to say they were running late. Very inconsiderate of peoples time and no communication what so ever. I would not recommend this company to anybody.
