I've been reading here for a while, but this is my first thread
I recently had a Trane 2.5 ton split system (R410a) installed and now I am concerned I will have problems down the road due to mistakes the installer made.
Problems started about 1 month after the unit was installed. While near the air handler, I noticed oil on the insulation surrounding the low pressure line. I called the installer, and we found a joint the installer brazed had cracked on the bottom and was leaking. I would say we lost several ounces of oil, based on how much we cleaned up using paper towels.
The installer then used the compressor to pump the refrigerant back into the storage tank in the outside unit. He then rebrazed the failed joint near the air handler. After I inspected his connection, I caught up with him outside and he said he was ready to turn the unit back on. I asked if he was going to pump down the system and he said he didn't need to because he purged a bunch of refrigerant (I know this is not legal). He then added 2 lbs of R410a and declared the job complete.
1) How much oil do you think I have left? Is this going to cause premature compressor failure?
2) Unless it's inside the unit, I don't think I have a dryer inline with the refrigerant. Is this an issue?
3) What would you do in this scenaro?
Thanks in advanced for your help. I'm trying to determine if I should be worried.... Also, FYI this job was done by one of the major south Florida HVAC companies, not a small fly-by-night operation. I'm a little suprised, especially with the refridgerant purge.
