Oh where to start... I bought a self install ductless mini split system from these greedy imbeciles through a retailer in September of 2015. All was just fine, no issues with installation or function with heat pump or air conditioning until May 2018. No cooling and it showed an error code. I also have, what I now realize, is a pretty useless warranty from Friedrich as well as a secondary one with a company that Friedrich pitches inside the package containing the instructions. I contacted my secondary warranty company's customer service and they had no HVAC companies that were "Authorized Service Repair" on their list that was near me. So after explaining what appliance I was talking about, they eventually called me back with a local company willing the service the junk. Tech found a leak in the line set where it connects to the outdoor unit, cost $291, not covered by warranty. I called Friedrich customer service and the incompetence festival began. Told them what the tech found and was told that was such a shame, but our tech support will help you, please hold. Get to tech support and I explained what was going on. As soon as I mentioned my model number I got a long pause and he mentioned that I have a unit that they don't sell anymore and it was known to have line set issues (leaks). He said he needed to have the HVAC company call him to discuss the diagnosis. After that happened, the HVAC company called me back and said that nothing is covered and I would be on the hook for the total amount. I was not amused. I called Friedrich back and got back to tech support, after a lot of complaining (by me), I gave him my model number and finally got him to agree to send out a new line set. YEA!, I WON! No, I just got more pain and suffering. After the line set arrived at the HVAC company, scheduled an appointment for them to install it. Eight days later they show up and within minutes realize the line set is the wrong size. Say what? Yep, not going to work. Friedrich doesn't even know their own products or parts. So, not fixed and even more angry now. I call Friedrich and firmly but respectfully, let them know my feelings. I get the standard, awwww and please hold. Talk to the next apathetic drone that now wants my sales receipt and HVAC invoices emailed to her. Did that yesterday (6/27/18) within an hour of talking to her. Next email from her said that she needed my HVAC company to call and talk to tech support. UH HUH Well, they did that today. I then received another email from her wanting ME to confirm the identity of the HVAC tech that talked to their tech support. Now I am on here letting all of you product researchers know just how much this company could care less about backing up their products even knowing it was a piece of crap. DO NOT TAKE MY TERRIBLE EXPERIENCE AS THE ONLY ONE. DO SOME SEARCHES ON OTHER PEOPLE THAT GOT SUCKERED BY FRIEDRICH, THERE ARE A LOT OF OTHERS JUST LIKE ME.
