    Great Service in a Timely Manner

    The staff at installing my two AC unit was on time and provided great service in a timely manner. The staff was a pleasure to work with and provided the necessary information required for the homeowner. Would recommend this company.

    Minimized Appearance of New Installation

    The installation of the gas pipe was accomplished in a creative manner by running the pipe inside the ceiling rather than below. This minimized the appearance of an unsightly pipe. The electrician demonstrated the knowledge and ability concerning the electrical components and placements of the Transfer Box.

    Warranty Covered Our Repair

    My Carrier furnace stopped working in October and needed a part. Rob, the technician from Clarkstown, investigated my problem, looked into the unit’s warranty, and the repaired was covered. There were no surprises; they were honest and thorough. The technician was knowledgeable and very pleasant to deal with. I would recommend Clarkstown in a second.

    Completed the Work 1 Week Ahead of Schedule

    I have already mentioned [Clarkstown] to my family and friends. The team that came to my house was amazing, they were on time and although having to work in my hot attic with heavy machinery there was no mess. The work was done 1 week ahead of schedule.

    Excellent Service from Professional Technicians

    Our experience with both the service technician who first visited us, Ricky, and the two technicians who installed our new heating system were very knowledgeable and professional. Thank you for the excellent service!

    Michael Schmidt

    Polite and Patient Crew

    Clarkstown Heating and Air sent three workers to replace my boiler. The workers arrived on time, were neat, cleaned up after themselves, and very polite. The worker who installed the thermostats was patient explaining how to set the thermostats. They finished ahead of time assuring that we would have heat overnight. I would definitely recommend them to anyone seeking a New Boiler, New Water Heater, or Air Conditioning System.

    Competitive Pricing and Great Installation Crew

    Clarkstown Heating & Air Conditioning replaced our aging boiler and hot water heater. Salesman was very knowledgeable and presented a couple options that would work for our home. Quote arrived in a day and was very competitive in price with other companies. Installation crew was extremely professional, very courteous and attention to detail was superb. I personally called the owner TJ, to let him know of the great job his team did from start-to-finish.

    Each of the technicians that have come to my home have been very courteous and friendly. Have even trusted them enough to be able to leave them unattended as well.

    Taking Pride in Their Company

    Had new A/C unit put in and very satisfied with the results. Had an opportunity to speak with Mr. Pastore, who is president of Clarkstown. This man takes pride in his company and stands behind his word. My highest praise to the technician, Tom, whose meticulous attention to detail and professionalism shows he is an asset to this company.

    Great Service, Even In Older Homes

    Our house is brick and stucco, built in 1900, and Clarkstown offered a system that seemed best for us. Three of techs showed up on time, finished the job, explained in depth how to operate the system, and left in the same day. They were polite, clean, efficient, on time and exceeded our expectations. Nothing is better than working with professionals! We are 100% satisfied with the product and the service.

    John M. | Ridgewood, NJ

    A Terrific Job from Initial Contact to Install

    Owners Dedicated to Making Customers Happy

    Several years ago they installed a new boiler and hot water heater. And since the installation there have been several issues that they’ve had to come back for but every time they came they were prompt and addressed all of my complaints beyond my satisfaction. It was always very important to the owners to make me, the customer, very happy. I would highly recommend their service. I’ve also used them to replace my central air conditioner unit and was very satisfied with the product and service.

    Phil M. | New City, NY

    Best Equipment & Workmanship, for the Least Cost

    The clean up was so good. We couldn’t even tell the crews were here and the work was done! We interviewed 3 other companies and ended up getting the best equipment, best workmanship, for the least cost. I was waiting for something to go wrong, but it never did.

    Mike Amodeo

    No Signs of a Major Installation

    Clarkstown Heating & A/C replaced our old AC system. The salesman was knowledgeable and answered as many questions as I could think of. The installation crew also came exactly when they said, worked through the day, and when I came home from work, they were gone. The house showed no signs of a major installation and the system was working, quietly cooling the house.

    Herb P. | Suffern, NY

    Smooth Transition in a Boiler Emergency

    You have made this large investment [Carrier Boiler] a smooth transition and kept your word every step of the way. Your sales representative really know the product and made me feel assured that I am in capable hands. The installers took the time to explain the installation process, including workings of the boiler, troubleshooting and maintenance. Thank you again!

    Marco Feldi | Rockland County

    From Our Planning Meeting, To Final Install, We Were Impressed!

    It was a pleasure working with your company. From our first planning meeting with TJ, to final installation of our new system, we were impressed. Your crew did a clean and professional job. They were able to answer any questions we had and your price was fair. Looking forward to a long relationship with you folks. Thanks again!

    Allan & Sheila Kerner

    Took the Time to Explain Everything

    I had my furnace and A/C units replaced. The installer, Clayton, arrived on time with his assistant. He took the time to explain everything to me, then they proceeded to disconnect the old units and connect the new ones. They laid out drop cloths so that they could keep everything clean, and when they were done they cleaned up and took everything with them. Overall, they did an excellent job.

    Frank Z. | Ramsey, NJ

    Knowledgeable With Attention to Detail

    The two employees that installed the unit, in my opinion, did an outstanding job. They were knowledgeable, neat and showed an attention to detail. They are a credit to your company.

    Bill Walsh

    No Mess Left Behind!

    Once the job started it was quick. The work men did not leave a mess behind, in fact if not for the generator itself, we couldn’t tell they had been on the property.

    Ross Barnes

    Prompt, Clean, and Customer Oriented

    I have never had workers in my home who were as talented as your men. They said they would be here at a certain time & they were. Their cleanliness at the job was unbelievable. Extremely customer oriented & for that I am appreciative.

    Jack & Wilma Zupko

    Prompt Response & Service

    My husband and I appreciate your prompt response and service whether or not it’s an emergency. When we had the 8’ baseboard extended in our sun room, Pat called to tell us he was on his way and arrived on time. Thank you for a positive professional experiences.

    Kathleen Waggoner
