"On Wednesday, 08/28/2024, I used the Angi app because my AC unit was not coming on and had a red light and I had suspected a compressor. Rocky HVAC came to inspect the AC unit. They told me that it had a leak and that they would fix the leak and then add freon for a total of $1,150.00, including a diagnostic fee of $75.00, which I paid same day (08/28/2024). The next day (Thursday, 08/29/2024) I called the provider and asked them to go ahead and repair the unit. They later called me and said that they had fixed it and requested payment. I paid the requested amount of 1,075.00 upon they claim of repairs, but then just a few hours later, my tenant called me that the unit was not working, and that the property was very hot. I called back Rocky HVAC on Friday, 08/30/2024 and explained to them that the unit was not working. They said that they would call me back and after waiting for several hours without getting a call back, I called again and this time they said that they will send someone back to the property. Rocky HVAC finally came the next day (Saturday, 08/31/2024) and upon looking at the unit, they told my tenant that the unit needs to be replaced. When I go to the property, my tenant relayed the information to me, so I called Rocky HVAC and asked why I was not told from the storm art that fixing a freon leak was never an option, but rather replacing the entire unit. They claimed that they had said so but it is extremely disingenuous because if they had ever mentioned that I needed a new unit, I would not have wasted time and money to fix something else. I asked them for a refund of $1,150.00, but they are instead telling me that they would rather credit me $500.00 towards a new unit."

"Brad had a lot of knowledge and explained the products very well. Brad was very prompt in all of our communications. We had a new Rheem heating/AC system installed with an air scrubber, as well as, a water heater.. It's only been a couple of days, but everything seems to be working great. We had a 21 year old system replaced. We are looking forward to some energy savings!"

"THIS COMPANY IS SCAMMING PEOPLE!!! -On 6/24/21, Farnen and Dermer installed a brand new YORK HVAC system in my home. Everything appeared to be fine, and there were no issues for 2 years. -On 8/28/23, I noticed an extremely loud buzzing coming from my outside unit, so I called them to come check on the problem. My unit was still cooling, but extremely loud. Glen A. showed up to diagnose the problem and seemed like a nice enough guy. After about an hour, he informed me that my entire indoor and outdoor unit need full replacement for a total of $10,900. (I paid $7,500 just 2 years earlier). I said, surely this was covered under warranty because the unit was only 2 years old? He then informed me that it was not because it was â struck by lightning and the warranty does not cover an act of god. -At this point in my head things were not adding up, especially since the unit was still cooling, both of my neighbors units were fine (townhouse) and he did not even check the inside unit. I told Glen I need to think about the replacement because that is a lot of money that I do not have at the time. Glen disconnected my outside unit completely before he left with the hottest week of the summer upcoming (95F-98F) and charged me $189 for the visit. -I am lucky enough to have a Fire Marshall as a good friend to ask him about the situation. This guy sees lightning strikes pretty frequently. He told me there is no way that my unit was struck by lightning based off of what I was seeing and also because it would have gotten to all of my neighbors units (townhouse). He informed me it is literally impossible. THE UNIT WAS STILL COOLING! -I decided to get a 2nd opinion from another company. The other company came out and told me that my compressor was bad and that there was no lightning strike to speak of. They also informed me that it was covered under the warranty and they could fix it. The technician said that he noticed the wiring on the outside unit was incorrect. There was a red wire crossed with a black wire. He said that is exactly why my 2 year old compressor went out. This company even put their findings in writing for me. They replaced my parts and got me up and running for 82% LESS THAN F and D! -I am not the only person this has happened to. It appears to be standard practice. You can see the attached pictures of reviews from other people in the same boat on the Better Business Bureau website. I will be submitting a complaint through BBB and demanding a full refund. This is pure predatory behavior and it is unacceptable!"
