We purchased a house about 2 years ago and which the previous owner replaced the air conditioner / furnace with a new system. The problem is that sometimes the condenser wants to start, or runs for about ½ or 1 second and stops and keeps going ON and OFF but never runs. Or sometimes the condenser will run and cool the house for about 15 to 30 minutes and stops cooling (although the condenser keeps running). We called an independent AC repairman, he immediately “found the problem” and told us that the new AC was not properly installed. He indicated that there was excessive high pressure of the refrigerant in the copper lines due to a plug in the system. He said he would never have installed this unit at this house and did not want to get involved trying to fix a problem cause by the installer of the new AC unit. He indicated that the old AC system used R22 refrigerant and the new Trane XR12 AC unit uses R410 refrigerant, and should have never been installed because any trace of the old R22 refrigerant left in the unit is not compatible with the R410 refrigerant and will cause the oil in the refrigerant to “harden” and cause the line to plug up and stop the AC from operating properly.
We then called the AC Company that installed the new AC, they have been to the house twice, the first repairman did not find the problem (we told him about the incompatibility of the R22 and the R410, and he said that he has never heard of this problem). The second repairman that came out and verified the very high pressure in the system and indicated that R22 and R410 refrigerants are not compatible and will cause the system to plug up and stop functioning properly, he indicated that the system needed to be “flushed out’ and that the “dryer” in the system needed to be replaced with a new one. I indicated they should be responsible for both labor and materials since the unit was not properly installed. He said they would call me back the next day (this was about 1 week ago); at this point I do not believe they are going to call back.
My question to an Air Conditioner Contractor: Do you guarantee your work and equipment for 5 years? And would you come back to fix the incompatible R22 and R410 refrigerant problem on a unit installed 4 years ago. Also, would you still come back even when there has been a change in home ownership? And yes we have the original contact for the unit in our hand and it indicates a 5 year warrantee.
