For several years, I have been a customer of OSI Comfort Specialists (OSI) for household heating. It was not until I had a problem with my Nest Thermostat that was installed by my air conditioning service company that I learned that OSI was also in the household cooling business.

Being a loyal customer of my air conditioning company, I had no intention of changing service providers. However, after learning some of the mistakes that my cooling company had made in the past few years, I decided to have OSI repair my thermostat issue.

Ironically, within a couple of weeks, I had both of my Airconditioning units fail on me. OSI had just completed installing an oil tank in my garage. I was already impressed on how meticulous their service team performed.

Without shopping price, I had OSI repair and replaced my household cooling systems. The owner of the company's father and son had taken personal attention to the project. I had several calls with Mike Levi, who helped me understand some of the challenges his team had experienced.

Being once an executive of a technology services company, I have experience with understanding the challenges of operating a successful services Company.

In the service business, a customer's requirements are the top precedence. A service company is required to provide skilled service and personnel with product expertise. Building trust and a rapport with your customers is essential for a service company's success.

I experienced from OSI the qualities that I would anticipate from a professional service company: patients, conscientious, polite, skilled, communications, and loyal.

I was a customer, in good standing, for 38 years when Mr. Levy said ""go somewhere else"" because I did not use 600 gallons a year in my little house.38 years of doing business. What a disgusting way to treat a long-standing customer. GOOD RIDDANCE.

I live in Manhasset NY. OSI is not the company it used to be. When it was run by the father, Richie Levi, it was a first rate, reliable honest organization. When the father was running the company, it completed a number of successful projects for me including A/C compressor, gas fireplace, minisplit installation, baseboard heating. They had earned my trust and reliance.

Unfortunately, it appears that the father has retired and the company is now being run by the son Michael Levi who may have a degree in the relevant trades, but has no idea of how to treat customers.

My furnace died in Spring 2023. It used the same ductwork as my A/C so I needed an new furnace unit that would accommodate the A/C coils like my old furnace did. Michael recommended a furnace unit and installed it. It was a fixed price job.

The heat worked fine. But the reinstalled A/C coils immediately started to freeze up. I had not experienced this with my old furnace. OSI sent service men twice to try to fix it. The first one blamed it on my filter claiming it was too fine a filter providing too much resistance to air flow. But it was the same filter that worked fine with my old furnace. So it didn't make a lot of sense.

Nevertheless, to test that theory, I ran the system without the filter. It still froze up. So they sent another technician who moved a cutoff sensor that was mounted in a position he thought might be mounted too near the A/C coils causing it freezing up. After that change, the A/C coils stopped freezing up even with the air filter in place. As far as I was concerned, all was good.

But then, much to my surprise, I received a $548 bill for the 2 service calls to fix the A/C coil freezing problem. It seemed to me that this problem was caused by OSI installing the sensor too close to the A/C coil. I thought this must be a mistake because the furnace job included reinstallation of he A/C unit so that it worked properly.

So I called OSI to discuss. The office said I had to speak to Michael Levi. I left a message for Michael asking that he call me. I received no call. So I called again. I was told he was on vacation. So I left a message asking that he call me when he returned. Again, no call, just continued monthly statements claiming I owed $548 for these two service calls to solve the A/C coil freeze up problem that arose after OSI did the installation.

I then emailed Michael laying out my objection to the $548 charge. Michael had an assistant Ben Gambino respond. Ben claimed the money was owed because the problem was caused by the air filter. I was astonished. This is the same air filter that worked fine with the old furnace. It is the same filter that i removed before running the system again and experiencing the freeze up that led to the second service call that solved the problem. He offered to reduce the fill by $48 to $500.

I replied that I hadn't yet heard a sensible explanation for why any money was owed. If they provide one, I would be willing to discuss it..

I received no response from Ben or Michael or OSI. Based this, it is clear to me that OSI's current management has little regard for customers or truth. Billing and defending billing at all costs is their priority number one regardless of the merits.

I would give them a zero if I could. My water heater is broken and I have CHW. I have been without one for 5 days and they they want to charge me $800 and then they say my soft water unit is in the way and want to charge me another $200 to unhook it. Then they will fuck this up and I will have to get Culligan and give them money to fix there shit.

All they had to do is send a second person here to switch it out if one person could not handle it and they refused.

I could write a lot more but these guys suck big time and are a complete rip off. As a result I will also cancel CHW.

We recently used OSI to redo our natural gas feed to our barbecue and set up an Oooni pizza oven. Mike and his team were completely professional for the entire process. The installation was top notch, the pizza oven is awesome and my barbecue is now the burning inferno the manufacturer had touted it to be! Highly Recommend them!

OSI has been servicing our heating, air conditioning , plumbing and electric for over 15 years. We are so happy with the service. They are available 24/7 and respond immediately. We recently underwent a home renovation where we would have been lost without their careful planning and guidance. Michael and his team are experts with utmost professionalism. We would highly recommend them for any or all of their services.

We've used OSI for 20 years. This week was the last straw. They serviced our a/c 3 weeks ago. It stopped working on Tuesday (94 degree day). We called and begged them to come fix it. They said they MIGHT be able to get here; they'd let us know in 2 hours. We found someone else who came right away. He said it had stopped working because the drain was clogged and gallons of water had backed up. He fixed it for as much as OSI charged for ""service."" We told him it had been serviced 3 weeks before and he laughed and said that whatever the ""service"" was, they didn't clear the drain or it would not have backed up. We told OSI and they called us liars. They said the service was 2 1/2 hours long. The guy worked here for half an hour tops and sat in his truck outside for a while, no way did he work in our home for 2 1/2 hours. Regardless, they refused to do anything for us, so we are done with them. BEWARE, OSI takes your money and does not provide the service they claim.

There are no words that can adequately convey what a top-notch company OSI Comfort Specialists is. The steadfast support they give their clients is taken from ""the old school"" method of business: the company functions at all times with honesty, reliability, professionalism and superb knowledge their field. I have used OSI Comfort Specialists for almost 40 years, and I write with certainty that there is no other company out there that can compare. They're simply THE BEST!
