Charlie and his team are the ultimate professionals in their field. They should be the benchmark for other companies. They inspected our unit, explained all the work that needed to be done, answered any questions we had, arrived on time, followed through with the work without any hiccups and were so personable. Thank you so much for your top notch services. We will be referring CNS to anyone and everyone!

I was impressed by their professionalism, cordiality and punctuality. They are miles ahead of any other pluming/heating company I've contracted in the past.

well, as Jamie and Charlie both know, I am not usually at a loss for words but the service and outcome and pleasure of dealing with them leaves me at a loss - a picture may be worth a thousand words but a picture of Shirley my new Weil-McLain boiler would not tell the story - CNS was the lowest quote I got - some were more than twice as high all trying to sell me a way too oversized boiler comparable to the one I had or slightly smaller but still too big - I am sitting here toasty and warm - responded immediately on very short notice - like 15 minutes - impressed me with their knowledge and sensitivity = my neighbor tried to dissuade me from using them saying they were underestimating my boiler size or didn't know how to calculate it - boy, am I happy to say that he was totally wrong but Charlie inspired confidence and trust in me - we had a few glitches along the way but none was their fault and they resolved promptly once the supply house that had provided the defective circuit board was open the next day - they installed a temporary thermostat since there was a problem with the old thermostat connection - they were attentive and responsive to my particular concerns and besides Charlie has great green eyes and a great head of hair as my mother would say - patient etc., etc. = enough said

The crew came in, no mess no fuss, did a fantastic job and moved on. My family and I are very satisfied.

If your home has any problems with the heating and cooling system, call CNS. Over the last two years, the heating and cooling system in my parent's home required some minor maintenance. Just recently, one of the central A/C units had to be replaced. But whether the job was big or small, CNS was always there for us. When you call for service, Jamie or Linda will take care of you. Each time I call, they are both very accommodating, professional, and courteous. They are always upfront about fees and scheduling appointments. I appreciate that they are very responsive to customer needs and they always keep me posted. The service techs are always prompt and professional. They always inform us on what the problem is, how it can be fixed, and what solutions are available to us. Whenever there is a home repair needed, half the battle is finding the right people to do the job, do it right, and at a fair price. But I have total peace of mind knowing who to call and trust any time our boiler or A/C system needs service. Special thanks to Jamie, Linda in the office and the service techs (Charlie, Steve) that have come to our home.

It's early in the relationship but they get high marks. Trustworthy, punctual, respectful of our time and property. And, they seem to take a longterm approach to the relationship, giving alternative solutions to an issue, with benefits and drawbacks of each.

CNS replaced 2 old furnaces and 2 AC units. Charlie was knowledgeable and explained everything. He provided options and suggestions. The staff is polite and responsible. Work was done neatly, on time and on budget. I priced 3 vendors and selected CNS based on price and knowledge.

Great experience working with CNS. We had our boiler replaced and Spacepak HVAC installed throughout the house. Charlie came to the house a couple of times to answer my questions and go through the whole process. The team got the job completed on time and were able to work independently while I was traveling. The installation actually went better than expected as they managed to avoid boxing any of the duct work which we originally throught would be needed. Jamie was great to work, responsive and patient in answering my various questions. CNS were also very competitive relative to other quotes I received. Overall, very positive experience and highly recommended.

CNS is great! We had several heating and cooling issues throughout a renovation and after, and they were always very responsive, on time, and courteous. The owner and all of the staff always made sure to explain everything to us and are always able to help and answer questions anytime they come up. We will continue to use CNS for all of our heating/cooling needs and highly recommend them! Thanks CNS!

CNS Heating & Cooling are the BEST – I can’t sing the praises enough! My AC died two weeks into summer, and I received an extensive/expensive quote from my usual maintenance company. A friend in Westchester County recommended that I call CNS, who has been his company for years and I’m so glad he did. Jamie (in the office) is professional, knowledgeable, and compassionate – although it was peak season and they were obviously busy, she scheduled an appointment quickly. Charlie was thorough and experienced - he clearly knows what he is talking about. He reviewed the system, gave estimates for the remaining life of different components, and then provided an extremely reasonable quote for the work that was needed right away. Extent/expense were less than my original quote, needless to say – no trying to gouge me for work that didn’t need to be done. The job was completed quickly and efficiently, without inconvenience or mess. Having relocated around the country ten times in the past thirty years, I value home contractors whom I can trust to give me professional advice and a fair price. I am so grateful to CNS Heating & Cooling, because they provide both. They are an honest, reliable, trustworthy family business with heart!

I called when my heat would not turn on for this fall season and was accomodated with a quick afternoon appointment. Charlie inspected the unit and explained that it was 20 years old and could be fixed but he would recommend a new gas furnace which is high efficiency so cost savings would offset new unit costs. I went for the new 96% efficient unit and it works great. We agreed on an installation date and it was installed within that day. Area was left clean and all waste was removed. Pleasure to deal with this family business and they are my HVAC vendor for sure

Very helpful and knowledgeable service. We use CNS for heating and cooling and have had an extremely favorable experience so far. They recently replaced our entire air conditioning system and we were very satisfied with all aspects of the process.

I am converting from oil to gas and had two companies to give us their estimates. The price of CNS' offer was lower, and the equipment efficiency was higher than in the proposal of the other company. But this is not about the price only. The quality of care and attention you get with CNS is the highest I ever met. The customer is treated as a part of the family, really! The installation was done in a very timely manner and efficiently. People who work for Charlie and Jamie are high great specialists too. I am very happy with them and would highly recommend them to anyone!

When our 66 year old gas boiler gave up just before Halloween we scurried around trying to get prices and find the right people to get us a new one. Luckily a neighbor recommended Charlie Robinson/CNS, who gave us our third bid, which was comparable to one of the others. But Charlie was very specific and persuasive about why the Navien was the right choice for us, and we quickly settled on him. He came to the house when he said he would and did a great job, both removing the old boiler and water heater, and installing the new Navien, and in making sure everything was tested and worked properly. They also did a very good job cleaning up, and were nice people to have around. We would recommend them to anyone without qualification.

We had a great experience with CNS. We recently moved into an older home without central air conditioning. I did a lot of research as our house has radiators and I suspected this would not be an easy job. I got several estimates ranging in price and design, some of them I'd have to sell a kidney to finance they were so ridiculous. From the minute Charlie walked in it was clear he was the most knowledgeable. CNS installed a SpacePak mini duct system that looks great but most importantly works great and at a very reasonable price. All work done very professionally and they came back a couple of times, after payment in full, to tweak the system until it was perfect. Also very happy with the CNS's payment schedule, a payment due at various stages of the installation which I thought was very fair & forthright. Good company, good people. Couldn't be happier with our new central air system! Seymour

Last week in 97 degree heat, our Air Conditioning broke down! We have a newborn baby so it was clearly an emergency. I called CNS, they arrived within a couple of hours and repaired our condenser. We have an older system that needs to be upgraded, but CNS repaired it and got us AC until we are able to get that done. They came quickly, the office staff was beyond helpful & friendly during my hysteria and they repaired our AC at a fair price. Very Grateful to CNS!

Charles is the consummate professional. He arrived when he said he would, and installed our central air conditioning unit. I had done lots of research and he priced the unit fairly and installed it expertly. I have and will continue to recommend CNS to anyone who needs heating and cooling work done.

Working with CNS over the past 15 years has allowed me to rest assured that we will always have heat or air conditioning when needed. Even the time I called on New Years Eve someone showed up and we slept nice and warm. They have installed both A/C and heat as well as water heaters. We had forced hot air and they converted it to air handlers with humidifiers. Nice. I think the boss's name is Charlie he's the one that came here.

I called in a few companies for estimates on replacing my heating system. I chose CNS because Charlie was by far the most knowledgeable guy I had in here. The installation went well, on time, neatly done and at a good price. I now have a Navien boiler that hangs on my basement wall, takes up very little space and provides hot water on demand. All that and they got me a rebate from Con Ed. I am very happy with my new heating system and most impressed with CNS. Thanks guys, great job!

This company is top notch...from initial contact with Jamie to estimate and planning with Charlie to actual install the service was timely and professional. We couldn't be happier. In fact we are planning to use CNS for all our heating and cooling needs in the future. Thank you CNS. You are the BEST!

CNS replaced our old inefficient air conditioning system with a new high efficiency system. They gave me a professional proposal, emailed me links to all the equipment info/brochure and they were very helpful and patient in walking me through my options. I was also able to get a 600$ Con Edison rebate and they did the rebate application for me too. From start to finish they were very helpful and professional and the AC system works great! Highly recommended company, will use them again!

I leave reviews in those rare cases when I am extremely satisfied with the services provided. Yes, I'm a picky and demanding customer, for I expect the best for my money, ergo, CNS comes highly recommended. They are professional, informative, quick in reply, honest, giving me an estimate for the work that needed to be done without additional costs, as many add later on. My Grandparents required the new cooling system installed in their home. Summer in full blast and we decided on a Ductless Air Conditioning with Heat. From the first contact, CNS showed me their commitment to my satisfaction as a customer. Charlie and the crew know their job, they were on time, units were installed neatly and are working now for several weeks (almost 24/7) perfectly, plus Charlie was kind enough to show my Grandparents how to use it properly too. Full service! I will use them again and defo recommend to family and friends.

Charlie and his team are the ultimate professionals in their field. They should be the benchmark for other companies. They inspected our unit, explained all the work that needed to be done, answered any questions we had, arrived on time, followed through with the work without any hiccups and were so personable.

The crew came in as scheduled, started handling their business, completed the work on time and moved on to the next. My family and I are glad we came across Charlie and his crew!

Excellent service quick and efficient nice Company to deal with!

We had to replace a very old leaking boiler, furnace and an inefficient hot water system. After 4 estimates we chose CNS Heating& Cooling to do the work. Charlie explained everything to us in layman’s terms, gave us options and suggested what would work best for us. The new installation was done efficiently and most importantly when promised. The guys prepped and cleaned up beautifully. We could not be happier with the work done. Thank you Charlie, Jamie, Linda and the entire CNS crew!

Anthony was recently here for my annual AC unit service and was very professional and courteous as he is every time he comes to my house!

CNS replaced 2 old furnaces and 2 AC units. Charlie was knowledgeable and explained everything. He provided options and suggestions. The staff is polite and responsible. Work was done neatly, on time and on budget. I priced 3 vendors and selected CNS based on price and knowledge.

I have used CNS on three occasions (heating, AC, and hot water heater). Everyone I have dealt with (Charlie, Anthony and Jamie) is knowledgeable, timely, honest and reliable. The first time I dealt with CNS was when I lost heat on the Saturday night of a long New Year’s weekend. Every company I called said no one was available until Tuesday. CNS was the only company willing to come to my home and the head of company, Charlie, came himself. On another occasion, when my water heater wasn’t working, Charlie walked me through the possible solutions over the phone before sending a technician to avoid me paying for a service call. I recommend CNS to everyone!!

I felt the whole crew was professional and worked very quickly. Most importantly, they were honest and suggested that I not replace some of my equipment which other A/C companies were urging me to do. I highly recommend CNS. John

CNS is great! We had several heating and cooling issues throughout a renovation and after, and they were always very responsive, on time, and courteous.

We will continue to use CNS for all of our heating/cooling needs and highly recommend them! Thanks CNS!

We have been using CNS Heating and Cooling for all of our heat and air conditioning needs for about 15 years. They are always polite and kind. They always provide us with units that work well, require little service and last. Whenever I have had difficulty with my units they have come with little wait time and resolved the issues with little trouble or cost. Most of the trouble has been from power outages or damage from storm debris. I have even been given help determining what to use in vacation homes outside their service area. I do not know what I would do without CNS Heating and Cooling to keep me and my family comfortable in all weather.

I am an architect and I deal with contractors all the time. From my experience, Charlie, Jamie and their crews are the best ones I've worked with so far. I would definitely work with them again. I especially appreciate that Charlie introduced us to the high efficiency combi boiler, which is reluctant to be adopted by some big traditional home companies (instead, they would sell you a new machine with old technology and make the cost 3x for you). CNS people are also very knowledgeable and charming. Overall, impeccable work, high efficient, helpful and cheerful customer service, and wonderful people.

Very helpful and knowledgeable service. We use CNS for heating and cooling and have had an extremely favorable experience so far. They recently replaced our entire air conditioning system and we were very satisfied with all aspects of the process.

Charlie and his crew were amazing. They are courteous and considerate. Professional and friendly. Most importantly they are organized qualified and talented professionals that troubleshoot and problem solve on the fly and do what they say in the time frame they say they will. Highly recommend. Prices competitive and fair.

My son recently purchased a house that was in need of major renovation before he and his wife could move in. Among the repairs to be made was the need to completely replace the old HVAC systems – heating, air handlers, air conditioning, etc. Because of my engineering and construction background, my son and his wife asked me to become involved in their project to help them coordinate with the many contractors that were required. The absolute best contractor I had to deal with was CNS – for many reasons. Charlie Robinson and his entire team of technicians in the field, especially Anthony, and Jamie, who runs the office, are an outstanding team of highly responsive, knowledgeable, and experienced professionals. Not matter what the issue or crisis, they always somehow made sure it got handled the right way, they were always pleasant about it, and their prices were fair. They demonstrated a unique blend of technical and customer service skills, which is very rare in today’s world of heating and cooling service providers, and more generally in the world of home improvement contractors. I strongly recommend CNS without reservation!

I am converting from oil to gas and had two companies to give us their estimates. The price of CNS' offer was lower, and the equipment efficiency was higher than in the proposal of the other company.

CNS has done great by us! We converted our boiler and furnace to an upgraded version and they did the work seemlessly! We will definitely call upon them if needed in the future.

They also did a very good job cleaning up, and were nice people to have around. We would recommend them to anyone without qualification.

CNS has come to my rescue numerous times to fix issues with my navien unit. Our Navien was installed improperly by a different company and CNS did not hesitate to help us repair issues. CNS is responsive, professional, knowledgeable and extremely courteous. I am so grateful to them for helping us with the nightmare installation we had by someone else.

We had a great experience with CNS. We recently moved into an older home without central air conditioning.

We couldn't be happier with our new AC. Charlie and his guys did a great job and even came back ( after I paid in full) to adjust something for me. Went above and beyond to make sure I was happy!

I have used CNS several times over the last year at my new home. They installed a new central air unit, fixed a heat issue & also a hot water problem. I highly recommend them for any job needing to be done. Their prices are fair, they are hard working, efficient & accommodating every time I have had a problem. I completely trust them to always do the right thing! Charlie is amazing & I couldn't be more happy with their services!!

We purchased a new gas furnace for our institution from CNS Heating and Cooling. They reviewed our needs and presented to us a replacement package that exceeded our expectations. The installation met the projected schedule and we were back in operation in record time. We wholeheartedly recommend C&N for any of your heating or cooling needs.

Service was timely and efficient. Caliber of work done was excellent! All work completed as described in contract. Removal of trash was obvious as work area was left spotless.

CNS recently installed a mini split in my house, last year CNS installed an entire central air conditioning system on the 2nd floor. Their pricing is reasonable and the work is performed in a very professional manner. They keep you informed of what is happening and they complete the work on schedule. The employees are always courteous and careful in the performance of the work and Jamie in the home office is always willing to help. I have also recommended CNS to my neighbors.

Jamie and Charlie were really great to work with. It was a pretty big job for a 4500Sqft 100 years old house, all ducts had to be installed from scratch.

Charlie and Jamie provided me with great advice for my home and budget. Even with an unavoidable scheduling change the communication was fantastic. I was guided through a rebate program which helped offset the cost of my new heating unit. I was further provided with excellent advice on maintenance of the new equipment. Since the work has been done I have made several referrals.

We had CNS install two mini-split units in a store we own. Charlie and Jamie are a good team, providing prompt contact when needed. When the units arrived, the wrong ones had been picked up from the warehouse, which required another trip to get the proper equipment. The installation went well enough, though one condensate pump turned out to be bad. Charlie replaced this at no cost to us. This is a small shop, so scheduling may require some flexibility on the customer's part, this is made up for by their reasonable pricing. We needed to hire an electrician separately, as CNS doesn't do that work. I would hire this firm again.

Charles is the consummate professional. He arrived when he said he would, and installed our central air conditioning unit. I had done lots of research and he priced the unit fairly and installed it expertly. I have and will continue to recommend CNS to anyone who needs heating and cooling work done.

I did a gas boiler conversion with them. these guys know what they are doing!

It was a pleasure to have Charlie and his team work on my air conditioning problem. They would not give up; they were determined to make sure it was working properly and it has been ever since they made the repair in June. I had another company in first and all they wanted to do was replace it even though the unit was only about 6 years old. I have already given Charlie's contact information to a couple of friends. A very positive experience all around.

They went above and beyond everything they said they would do. CNS brought on more men to help replace a central air system that went in the middle of a heat wave. On time, great cost, very informative and always responsive!

After researching a number of companies to convert my home heating to natural gas, I chose CNS. They had positive reviews online and they earned another one from me. They just finished the installation yesterday. It's a rather long process because of the scope of the job, but well worth it. Their pricing was fair and exactly where it should have been. I received quotes from other companies that wanted DOUBLE what CNS charged. I would strongly recommend anyone in need of oil to gas conversion, or any heating or cooling needs for that matter, use CNS. I'm probably going to have central air done in the next year or two and will certainly be using CNS.

CNS Heating and Cooling changed us over from oil to gas heat. The work was done quickly and professionally. All of our questions were answered thoughtfully. There were no surprises. Every person in the company, from Jamie in the office to Charlie in the "field" were intelligent, capable, polite and professional. I would use them again in an instant and recommend them to all my friends.

I had a great experience with CNS. They were very quick to help in any and every way possible throughout the process. Gas conversion and central air was put in my house inside 2 weeks. I had a question about the setup after they finished the job and Charlie was at my house the next day. After the job, paperwork for all my rebates with con ed started. Jamie was able to walk me through everything to get it squared away. This seemed like a lot of work to be done, they made it a piece of cake.... I would refer CNS to anyone.

CNS is always available when we have a problem, even holidays and weekends! Thanks Charlie and Jamie!!

We have used CNS for about 10 years now. They were recommended to us by two neighbors who had been their customers when we moved into the area. All of us are still clients after all these years. Charlie rebuilt our heating and A/C system and installed a new hot water heater after ours gave out shortly after we moved in. He has worked with us to resolve other issues as well and is an expert at what he does. Jamie handles all the administrative details and is always professional and such a pleasure to work with. We have recommended CNS to several friends because Charlie and Jamie are genuinely nice people who are extremely knowledgeable, fair, and trustworthy.

I had a major emergency issue with my boiler where my house almost caught fire if I wasn't paying attention. I contacted CNS and they immediately responded and made my house a priority. It turned out that I needed my entire boiler replaced which wasn't in my immediate budget but they made a reasonable accommodation for me that I'm greatly appreciated. That's not the first time they came out to assist me and I will highly recommend them. I've had bad experiences with other companies and when I found them it was a blessing and when you find a good company you must hold on to them. I hope this helps anyone that's interested in using CNS. 5 stars hands down!!

They were punctual, clean and efficient. Charlie and Jamie were always willing to answer questions in addition to give guidance going forward. Would recommend them to anyone looking for HE Heating Units.

I have been with CNS Heating and Cooling for 10 years now and have alway been satisfied with their service and attention to detail. If you want a reliable company CNS is it. They diagnose your problem and fix it the first time. I would highly recommend them to anyone.

Working with CNS over the past 15 years has allowed me to rest assured that we will always have heat or air conditioning when needed. Even the time I called on New Years Eve someone showed up and we slept nice and warm. They have installed both A/C and heat as well as water heaters.

They gave me a professional proposal, emailed me links to all the equipment info/brochure and they were very helpful and patient in walking me through my options. I was also able to get a 600$ Con Edison rebate and they did the rebate application for me too. From start to finish they were very helpful and professional and the AC system works great! Highly recommended company, will use them again!

I called in a few companies for estimates on replacing my heating system. I chose CNS because Charlie was by far the most knowledgeable guy I had in here. The installation went well, on time, neatly done and at a good price. I now have a Navien boiler that hangs on my basement wall, takes up very little space and provides hot water on demand. All that and they got me a rebate from Con Ed. I am very happy with my new heating system and most impressed with CNS. Thanks guys, great job!
