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.

Thersa Casscless

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.

Ernest Muth

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

An Entire Staff with Great Work Ethic

We were very pleased with the professionalism, courtesy and work ethic of your staff from the sales personnel to the installation crew.

Allan Douglas

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

Questions Answered Thoroughly

Thank you for helping to make a difficult time more comfortable. All of your employees are professional, pleasant and responsible. I especially appreciated the thorough way all questions were answered.

Dayna Boone

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.

The Francesconis

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!

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.

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.

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.

Steve Martigneti

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.
