The problem turned out to be much more serious than initially expected, and resolving it required several visits by Mazgan's technicians. Although the repair process was more involved than anyone had anticipated, the company continued working on the problem until it was fully resolved. Throughout the process, the technicians proved themselves to be responsible professionals who worked hard to solve the problem. Mazgan arranged for the necessary parts to be supplied by Navien. In several cases, obtaining those parts at no cost required Mazgan to negotiate with Navien on my behalf. The company was also very accommodating regarding the overall cost of the repairs. In the end, Mazgan proved to be a reliable company that stands behind its work and can be trusted to see a difficult project through to completion.

Then Mark said it would cost $3000 to get up and running with new wall unit install. When I complained, they said they would work with me. (I expected $2K to finish). When a used unit arrived on site for replacement, he instead sent a bill for $5500 to install, trying to weasel $8000 out of me to change out a simple wall unit 7' high on a wall. He then knocked it down to $4300. Still ridiculously HIGH!!! They add in line items like $500 crane fee for their lazy asses to lift the 15 lbs unit in the air. They originally tried to charge $225/lbs of R410A freon. I could go on and on. In the end they left me hanging but thank God they did. I called another company that charged me $2600 total to install a brand new unit ($700), with 11 lbs @ only $95/lbs of freon fee and none of their predatory fees- just an hourly rate. Mazgan is so unscrupulous. I hate vendors like this. STEER CLEAR. I cannot express this enough.

When I called to make the appointment yesterday, the lady who answered the phone told me that they could show up today. What really surprised me was that the first hour cost $350, and a subsequent hours cost only $300 an hour. When the two guys showed up at 9:30 AM, I told them that I was interested in a check of the coolant levels in both of our yards. I followed the guys downstairs to open up one of our two units, and it took both of them just over 20 minutes to open up a side panel while using a 7 inch straight drill bit. Based on that pretty unimpressive performance, I told them not to check the coils on the second unit, but rather told them that again I wanted the coolant levels checked. One of the guys told me that he refused to put the coolant in, that was required, because he did not physically inspect the coils of the second unit. He lobbied for the two of them to open the second unit. I asked them to leave. If you're gonna charge $350 an hour, you need to be pretty amazing at what you do. I paid $390 for 2 guys to clean one set of coils and put in a filter that I provided; no 'Freon.' They were anything but helpful and I won't use Iceberg again.

He and the customer support team at least partially restored my perspective of the NYC's AC repair service industry. We will definitely go back to them for any HVAC issues in future. Highly recommended.

My experience with the team from Panda HVAC was the most positive experience I have ever had with any contractor. This included my interaction with Tanya in the corperate office, who was instrumental in setting up all of my appointments. She was always pleasant and patient when explaining all charges. When the 1st team arrived (Imam and Thomas) my 1st thought was, "Oh no! How is it possible these guys are going to be able to handle such a big job of replacing my furnace and AC unit." They looked so young! Well, after their 1st day, I was completely impressed with both Iman and Thomas' professionalism and their level of expertise. Imam had scheduled vacation time during this project and he was replaced by Nazar a few days after. Nazar was equally skilled and I felt reassured that I was in good hands. There were a few unexpected challenges along the way but both Nazar and Thomas met them with great solutions. I was impressed with how neat their work was. They both went above and beyond every step of the way. They were both excellent trouble shooters! Even though this was a costly poject, I am so thankful that I chose Panda HVAC. They did an amazing job! They were pleasant to work with and I never had to worry that they were taking short cuts or incapable of handling the task at hand.

I was desperate to get my through the wall AC unit installed, as I this was the third unit I had tried to order from Home Depot (long sad story) and it was in the high 80s. I woke up early and planned to be available all morning, just to find out the installer I had scheduled made a mistake and wasn't available. Fortunately, Ayrat was. I was able to schedule with Climate Helpp last minute, they were very responsive and flexible, and gave me a very fair price. Ayrat was on time, checked with me to see if everything looked good to me and asked if I wanted anything adjusted. He waited to make sure the AC was working properly, then cleaned up the area and removed the old unit. I hope I get a chance to work with him again soon, although I also hope I don't need to!

I specified the model number, BTUs, and the fact that it was an upper window installation. I had the person on the phone double check to make sure they do actually repair large units installed in upper windows. The person on the phone assured me they do. I was told I could have an appointment 8-11am today with Jorge, and got a text confirming that. I texted back requesting that Jorge call me in advance if he thinks my window AC unlikely to be repairable. I got no response so I assumed the text chain was unmonitored. I rearranged my day, got up before 8am, and waited. At 11:15am, no one had come, so I called. The person on the phone was very apologetic and said someone would call me back immediately to let me know when the tech would arrive. I rearranged appointments for the afternoon. No call. I rearranged more of my appointments for the afternoon. I called again at 1:30pm: same apology and promise. No call. I rearranged more of my appointments for the afternoon. I called again at 3pm: same apology, same promise. In desperation, I told them I was about to write a bad Yelp review. That's clearly the ONLY thing that made them bother to respond to me because, finally, at 3:15pm, Brenda texted me on the same text chain (so the text WAS monitored after all): "I am sorry for window AC we usually replace them do not perform repair." What??? They had confirmed that they DO perform such repairs. And even if the phone person had been mistaken, they KNEW they had made an appointment with me 8-11am. But no one had bothered to contact me to tell me anything! They knew I was calling again and again begging for a response. No one WOULD have contacted me had I not finally told them I was about to write a review. They are obviously totally unprofessional and don't care how much disruption and waste of time they cause their clients.

Immediately after the service, my 4-year-old PTAC started making noise and the thermostat stopped working properly. I called them back, and they sent a tech who insisted nothing was wrong--clearly to avoid holding the first tech accountable. I then hired another company, who found a leak and confirmed the unit was losing freon. When I confronted YuHan, she claimed it was "impossible" their first technician caused the problem and that their company "never makes mistakes." That's hard to believe when they couldn't even clean a filter. She asked me to send pictures and receipts, but it's pointless--she'll just deny responsibility no matter the evidence. She basically said I am lying. I attached a picture, this was AFTER the "cleaning". You can see the line thats leaking. The rep went as far as saying I am taking pictures of a third unit they never serviced, as if I am trying to scam them for a machine that wasn't working. Its ridiculous There are far better companies out there, and I can recommend a few. My advice: stay far away from these guys.
