Regular Central Air Conditioner Icing Up.
About a week and a half ago, we noticed that our central air conditioner did not seem to be working properly.
We went outside to look at the unit and there was ice forming all over the coils inside the unit and on the tube leading to the house and ice ran down into the unit inside the house.
We changed the air filter and cleaned the coils inside the unit inside of the house and vacuumed around the motor. A repairman came and said that we needed to add more refrigerant. He charged us 330.00 to add the refrigerant and said that our motor was very dirty.
Said he could clean it for 100 more but it did not need to be done any time soon. Air conditioner worked great for a week and a half and then we noticed the same problem. The house did not seem to be cooling off enough and ice was forming again. What do we do now?
