False advertising, dont use
Just boiggt a new house. Their website advertised free estimates. Then when they came to my house they charge me $200 because they "looked at my furnace for 5 minutes" Clearly they dont offer free estimates but falsely advertise that they do. Dont use this company.

The technician, Anthony Hanratty, did an excellent job of diagnosing my heating problem and fixing it. He adjusted the boiler temperature and allowed the heating system to bring the room temperature to a level that matched the thermostat setting, which had been the original problem. His approach was very professional and he explained his procedure in a step by step manner that was clear and easy to understand. Thanks Anthony for a job well done.

Avoid at all costs!! Clarkstown was recently acquired by some Long Island company and their prices are now 6-8x what other companies are charging. I was quoted $2400 for 1-2 hrs of work. Anyway I called another local company and they got it done in 1.5 hours for $325+ $80 in parts. Below is a link to a Reddit post I made about the estimate corroborating how outrageous it was. https://www.reddit.com/r/hvacadvice/s/HnoQGXvVFn
Very professional for over charge and unprofessional with service even after paying $1000 plus job not done I have to call someone else to finish the job
I had a problem with my heating unit. The technician came and told me it was a Honewell Zone valve which was not working. He replaced the zone valve and spent in total 45 minutes to fix the issue. The valve costs $57 on Amazon and I was charged $719 including tax. It was a total rip off. Clarkstown Heating has replaced 3 of my Air condition Units, Heating boiler and the water heater. I have been a loyal customer of their business and I get ripped off. I will never use them again. I just realized they are under new management. I don't trust them and will never use them.
Highly overpriced. We immediately got quotes and comparable companies were half of what Clarkstown quoted us. They used to be good before the merger with Universe.
We were quoted more than 2x vs other companies for a boiler transformer replacement. Also charged $160 for a 5 minute visit as a “dispatch fee”. Very disappointing especially since we have used Clarkstown for our HVAC issues in the past.
Buyer beware, outrageous price gouging
We had used these guys in the past and we found their employees to be knowledgeable and their prices to be competitive. This week our boiler stopped working and we had one of their techs come out and take a look, turns out we needed to replace a thermocouple and a release valve. Their guy proceeded to give us a quote that almost made me spit out my coffee, the tech quoted us almost $2,200 dollars! Neither of those jobs are particularly difficult enough to warrant that outrageous a price. We ended up calling someone else and they ended up doing both jobs for $350 and were in and out in just over and hour. This company has turned to price gouging to try and take advantage of customers who are in a bad spot during the winter time, stay away from them.

Called for an emergency service, proceeded to charge flat fee of $700 to replace a "dead" smart thermostat with a digital programmable one with work done well within half an hour.
I’ve used this company before, few years ago, that’s why I called them. I needed a relay switch for furnace. The part cost $350 the tech, who was very nice, was here 1/2 hour, the bill came to 1,700. They told my sone, who was there to meet the tech, they’ll cut the price to $1,200 if we purchase the $500 maintenance package. When I called to get an itemized bill they told me they don’t do that it’s a flat rate!!
Clarkstown recently installed a new boiler for my Church at our parsonage. I was very impressed with the quality of the installation. The technicians solder joints were perfect, the piping polished and the routing for zones laid out well for ergonomics and maintenance. All of my expectations were met.
Overpriced and not reasonable. We had parts under warranty and got charged over $1k for a little over an hour of labor. We had to keep calling the office to follow up on scheduling the service, first they had to check if the parts were available, another call they couldn't reach their service department to see when they're available and they would call back, which they did not.
Of note, the tech himself, Brian, was amazing, polite, and nice. I would recommend him if he ever worked outside of this company. He tried to call and see if they could lower the price for a maintenance membership fee and when he called the office he received a flat out no. The office didn't even try to look into it or anything, it was just NO.
Overall, this Clarkstown/Universe is not here to work with customers, they are just here to get the money. They could not give a detailed receipt of what is done, they basically work out of a flat fee or whatever they want to charge.
I normally don’t write reviews, but I felt this one needed to be shared.
About five years ago, I had a central A/C system and a mini split installed in my home. The installation went smoothly, and everything worked great at first.
The following summer, however, my A/C started blowing warm air. I scheduled a service call, which cost $180. The technician tested the system and found it was 4 pounds low on refrigerant—even though the system was only a year old and should have had 8 pounds total. They added dye to check for a leak and returned a week later but found nothing. I was charged again to add the missing refrigerant. After some discussion, the company did the right thing and offered a discount, which I appreciated at the time.
Fast forward to today, my mini split (now five years old) still works fine, but I noticed mold growing in the fan—something I’ve since learned is common. I called to schedule a cleaning, and was told I’d first need to pay $180 for someone to come out and “assess” the cleaning needs. Then, I’d have to schedule another appointment for the actual cleaning, which starts at $399 per unit. They also informed me the $180 assessment fee would not be applied to the cleaning service.
All I wanted was for someone to come out and clean the unit—I’m not having any performance issues, just concerned about the mold. Unfortunately, the process and pricing felt like more of a cash grab than customer care. It’s disappointing to see how differently the company treats customers after the initial install is complete.
I used clarkstown heating As I installed a new heat and air conditioner in January 2025 Dead of winter Life saver especially when my heating sustem failed But the air conditioner was not properly installed The technician David came to make sure the air conditioner was installed properly David determined that it was not properly installed no cool air Fortunately David being an honest person requested assistance and made sure my brand new air conditioner was working properly Ask for David for good attitude attention and competent reliable service Ask for David The owners of this company need to know what happened Thanks George
Big thanks to TJ Pastore, owner of Clarkstown Heating and Air Conditioning for being a gentleman and for willing to listen to the customer and for making things right. Also thanks ton the fantastic crew who showed up to replace my condenser coil. Sometimes things don't go smoothly and it's good to know this owner takes pride in his company and customers.
This company has done a lot of work for me over the years. They are efficient and quick to respond. Pedro, their technician, does a great job and I would welcome him back. We recommend Clarkstown for all your home needs.
Had a new air conditioning system recently installed. Technicians were very professional, neat and clean. Arrived on time and finished on time. Everything was explained to me. Beautiful installation and great job. Have been using them for 28 years and would never even consider going somewhere else. Thanks for a terrific job!
