My downstairs mini splits were installed Nov.6, 2021. Since the upstairs was not installed, I could not use them. My upstairs units didn't get installed until Dec. 7th. Throughout the winter, I had my downstairs (where I'm sleeping) on and my home NEVER got warm. I had it up to 84 degrees and my house still was in the 50's inside. I contacted my contractor on Mar 21, 2022 to let him know my units shut off automatically and that while the remote works, the units don't turn on. He didn't come to my house until the 3/28 . He was a no show two other times when he said he would be at my house, and I was not notified. I had to contact him. It is now June 14th. My units still do not work. I have asked for a new compressor, he said the supplier won't give provide it.On May 13th he said that he spoke with a tech for the complany and that there is one small part that needs to be ordered. He told me my units would be up and running 2.5 weeks from then. They are not. I have made mulitple attempts to get what I paid $13,000 for working and it is still NOT. I have not had heat, nor do I have air conditioning and the temps have been in the 90's. I have all the interactions with this contractor on my text messages and will be glad to forward them to whomever if need be. I just want my units working and this business transaction completed. The only time this contractor communicates with me is if I initiate contact. I want this resolved and I have no idea what else I can do.
