    5.0 James M. Harrison, NY

    Jaime Ruggeri is an absolute pleasure to deal with and immediately sent out a wonderful technician, Anthony Maravilla, who is an expert in all types of A/C systems. Anthony's maintenance and diagnostics skills are top notch and he is extremely courteous and professional. I highly recommend CNS for their professionalism, quality of service and great pricing!!!

    we chose CNS based on Home Advisor and their high ratings. Service was punctual and friendly. Even though the technician (Anthony) wasn't used to the system, he immediately pinpointed the problem and made the repairs. They are completely honest as they didn't charge for any new "replacement parts". We will be asking them to help us install a separate ductless system in the next few months.

    0.50 Haiping S. Scarsdale, NY

    Very negative recent experience. We waited for more than 3 weeks in the hot summer days for CNS cooling and heating to fix our central AC. They tried to force us to accept their pricing without giving details of breakdowns for the parts and labors. When it turns out the parts are still under warranty, CNS started to try to charge us skyrocketed labor fees. They refused to provide any transparency in their pricing or any negotiation. In the end, we wasted more than 3 weeks and money without resolving any AC issue. We ended up finding other contractors to resolve our AC problem. The owner, Charlie, emphasized several times that he did not care about the suffering of the customers caused by them. Strongly DO NOT recommend their work and service!

    Response from Company:

    We do our best make to each and every customer happy. Haiping called us to schedule an AC service call immediately following tropical storm Isaias, however she had no power due to that storm for nearly a week. In addition, she cancelled a scheduled appointment. The wait she endured had nothing whatsoever to do with CNS. Haiping's ECM motor burned out needing replacement. It was CNS that informed her from the very beginning that her motor was under warranty & she would only be charged for labor, so there was no breakdown to give. Our prices are very competitive as proven by our many good reviews, however, Haiping was very intent on a "negotiation" We therefore promptly refunded Haiping her deposit for the motor installation and parted ways. We regret that we could not help Haiping to her satisfaction and we wish her all the best.

    Excellent company..... They installed a new central A/C system for us last week. From the first phone call until completion of the job, everything was as good as it gets. We are extremely pleased. The office staff to get the estimate, set up appointment, answer questions, etc., (mostly Jamie) were extremely fast in responding, patient, very nice and professional. After approving a good price, installation day was scheduled quickly. Our unit is in the attic, mainly through a small hatch in the closet ceiling but it was no problem for them. The whole job took just a few hours and before they left, they cleaned the work area. The unit is working perfectly and we are so happy to have air conditioning again! I would highly recommend CNS Heating & Cooling!

    5.0 Denis O. White Plains, NY

    Responsive and helpful. Found a less expensive fix for a problem.

    5.0 Lisa M. Peekskill, NY

    Charlie and his team are the ultimate professionals in their field! They should be the benchmark for other companies. They diagnosed the problem with our old furnace/ac system (we had moved into a new house with existing system) and installed a brand new system for us in no time. They were also so personable and answered any questions we had. Thank you so much for top notch service! We will be recommending CNS to anyone and everyone!

    5.0 Francisca S. Scarsdale, NY

    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

    1. Verify Trade License
      HomeAdvisor checks to see if the business carries the appropriate state-level license.

      As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
