At least 4 times wihin the past of couple of years, i had called A/C maintenance people to take a look at my a/c unit for not giving cool air. They all found freon level was too low. Filled the freon, tightened the valve here and there. But few weeks later, the same problem again. One a/c guy said coil was leaking and gave me an estimate of $3000 to replace it. i called other a/c guy for his opinion. He said there was nothing wrong with coil system. Coil is in my attic. i did notice, attic gets cool when i run the a/c although there is no a/c vent in attic. then i found out there was cold blow of air coming from joints around the coil system box. is it normal to get cool air blowing out from coil system? I taped all those joint openings. i also hear some hoarse/dry noise coming out of the coil in the attic that i do not hear from another coil system in the first floor (we have two a/c system, one for each floor). Eveytime a/c guys show up they fill up the freon, clean the shrubs around compressor, tightens the valves, but the problem does not go away. i wanted to put this problem here before calling a/c guy for the fifth time. what should i ask him? why they can not fix the leak which is the obvious problem? How do i find out the leak and fix it?
