Post closing repairs

[Alyssa Robbins]

Hello,

I bought a house in November of 2018. When we initially looked at the house the air conditioning unit was not in working order. So, we put in the contract that it needed to be repaired or replaced and needed to be in working order at the time of closing. Well, we are in Missouri and in November they said they had put in a brand new unit, and it was blowing cool air during the final walk through. 

Now it is July and very hot, our air conditioner is not keeping up and will not even keep our house at 76 degrees without struggling. We had someone come look and when they replaced the unit the sellers did not match our coil inside with the unit outside so our unit is pushing half a ton more air than the coil can handle. I feel like part of the sellers repair or replace was to do it right? The person we had come look at it said not only did they not match the coils but they also didn’t clean out the lines which is standard for putting on a new unit or a new to the home unit. What do you guys think? Is the seller responsible for this since the did it improperly?? The unit is not actually new by the way according to the serial number people have not been able to sell it new since 2006.
