I recently purchased a home in November of 2018 and noticed that they used Carrier as the furnace and air conditioner. So my naturally instinct was to research them because I've never had them. The reviews were good for the furnace but the air conditioner I couldn't find from the serial number. I had to call carrier and ask them about the model I was getting and it took him several minutes looking it up to find it and when he did his reply was this is a builders grade and that I couldn't even register it because that serial number and model really don't exist as a consumer model. So I reached out to the builder through emails and calls and told them what I was told and they really in a sense blow me off. So fast forward to about June when it was time to finally cut it on, It did not work the first day I turned it on. I was told to contact the ProHome warranty for the home. They acted like it was my fault and sent someone out two days later, by then we are baking in the house. He HVAC repairman said it was missing a part on the inside. He fixed it and it was fine, for a month. Then in July I had to call again because the air was on to hold at 74 and the thermostat stayed at 84. I called ProHome again. Then sent someone out and I had to take off work to be there to let him in. So we go in the basement and it is water on the furnace and the floor. He went outside and the pipe was cracked because he said it was not a good weld on it when it was installed. Now today, 9/11/2019 we turned the air on at 9am and the it was saying 79 in the house and throughout out the day it went up to 81. This is the third time that this air conditioner has given me problems and now the home warranty is about to expire and I will be left to foot the repairs for this air conditioner that I have complained about since I could not warranty it. It truly sad that you spend all this money and then they put *** appliances in the home.
