Diamond Air Conditioning And Heating LLC

My A/C mini split stop working and give E1 code on the screen. I filed a claim through my Choice home warranty company. Diamond Air Conditioning and Heating LLC was assigned. Dean came on Jan 19, 2026 and start run diagnostics. He said that unit has Freon leak and he will need to open the outside unit to find leak. So he told me that usually compressor is leaking and to fix that it will cost around $3k, because warranty will not cover or my other option to replace unit for $2.5K. Also he told me that Choice Home Warranty will not cover any of those expenses. I end up paying $75.00 fee and let technician go, because I was not ready spending this much money for 4 years old unit that I paid with installation $1900.00. I spoke to Choice Home Warranty and explained situation and they said that they will find another company to check my A/C. Tech from Sears came and found that outside main module (brain) did not communicate with inside unit and that cause E1 code. He got approved by Choice Home Warranty company to replace that unit and cover the labor. When tech from Sears came back to replace that module in outside unit he found snake inside that module that cause this communication error code. Now my A/C is back and working. See photo evidence. So, I would not trust Diamond Air Conditioning and Heating LLC after that experience.

Avoid this company at all costs! I had an absolutely terrible experience with Diamond Air Conditioning And Heating LLC (4642 W Colonial Dr, Orlando, FL). On August 11, 2025, I called them because my AC in Clermont stopped cooling. Their technician claimed it was a leak in the evaporator coil (which was under manufacturer warranty) and charged me $1,300 in labor to replace it. The coil was swapped on August 15th, and the AC worked for just a few hours before breaking down again. When I called back, they only showed up on August 17th, and suddenly the story changed—the problem was now supposedly with the refrigerant lines under my house, requiring an even more expensive fix. This means their initial diagnosis was either flat-out wrong or deliberately incomplete. I was left with a non-functional AC and a $1,300 bill for nothing. To make matters worse, after I asked for a refund, they stopped answering my calls completely. The technicians then abandoned me by telling me to “call my home warranty,” left the AC unit unsealed, and didn’t even cover up the holes they dug while checking for leaks (Pictures attached). Extremely unprofessional, dishonest, and careless. I feel ripped off and taken advantage of. Save yourself the headache and money—stay far away from Diamond Air Conditioning And Heating LLC.

I ordered a unit from the company back in the third of October. ETA was 6-8 weeks from the manufacturer. Here we are in January and no unit. I’m ok that delays occur. The reason for the poor review is that I have called this company at least bi-weekly since mid December to get an update on the status of the unit. Ashley, the receptionist is an absolute joy. I am confident that all messages have been relayed. Her manager…..well I wouldn’t know because he has yet to return any of my calls to give me an idea of where we are with this unit. I live in Canada. I understand that delays occur so timed my visit to my Florida home for 10 weeks after expected delivery. I flew down here and this gentleman is still not taking my calls despite message after message. The service has been disappointing to say the very least but I’m 10 weeks in on a specialty order. Too late to start anew.
