My unit seems to have a leak and two weeks ago, a tech came in and recharged without telling where it leaks.. He simply told he wouldn't know and asked me if I want it charged. It was hot day and I had to have a cool house because of my baby. He guessed it was leaking from condensor unit because surchage cap was oily.
Since then it worked and today, my unit does not seem to work at all. Outside fan blows cool air instead of warm and I don't see any condensation on outside unit. Lucky, cold front came in.
I plan to call another tech or maybe the same tech and ask what's going on. However, I doubt if the tech from the same company will find anything and wanted to know if there is anything I need to ask them to do to find the leaks.
I also plan to replace my outside unit and got some quotes to replace. My evaporate coil is only 4 years and all techs told I should just keep them since it's relatively new. However, can the evaporate coil be leaking as well? and does a tech have a way to detect a leak?.
