I've asked this previously and am attempting to get a consensus of opinions.We had a new air conditioning/heat pump system installed in our home in June 2014. In June of this year the began having problems with the internal coils freezing up and no air coming through the vents when the air conditioning was on. The original installer first said it was a problem with thefilter and recommended we change it immediately. We did but over the next month the problem became chronic. We had a 10 year parts warranty but no labor warranty beyond a year and the original installer wanted $119 for a diagnosis and then whatever cost beyond that for the repair. We chose to go to another company whose charges were lower. The second company came in and the following is their diagnosis:"Performed diagnostic on Goodman heat pump. Client had unit installed about 2 years ago. Unit had been not cooling properly lately. When arrived found refrigerant charge low. Notice large oil spot around suction line entering air handler . Pumped remaining refrigerant into outdoor unit. Pressure tested at 375 psi. Tested for leaks with soap bubbles. Found leak at field braze connection on top side of 90 degree copper elbow. Repaired leak. Purged system and pressure checked 375. Leak tested with soap bubbles. Found no other leaks at this time. Evacuated to 350 mircons. Opened valve and balance charge added additional refrigerant to proper charge level. System is cooling at this time.System pressures- 147psi/345psi, Superheat - 16F/Subcooling - 11F. Supply air- 67F/Return air - 88F. System is under manufactures warranty. Leak in line was not due to failed or defective component ."The conclusion of the second company is that the installer did not braze the joint properly when the unit was first installed which lead to the leak. To quote the technician from this company when he diagnosed the leak:I contacted the original installer who insists that there is no way to tell what caused the seal to fail or when it did and it could have been due to "vibrations" or "contaminants in the brazing". He also insists that if the leak had been present from the time of the installation, the system would have failed immediately or shown a leak during testing at the time of installation not 2 years later.We forwarded a demand letter to the original installer asking them to pay for the repair. This is their reply: "The air filter installed in the HVAC system is not designed to operate for two years without causing restriction to airflow across the indoor coil. Operating the system during the heating season with a restricted air filter will cause significantly higher operating pressures and vibration in an HVAC system utilizing R410A refrigerant. This condition could have been easily avoided if the recommended maintenance intervals were followed.I do not believe this to be a maintenance issue which the contractor has tried to turn it in to. We chose not to buy his $230/year maintenance agreement offered 3 months after the original installation and either the business owner or the office manager mentioned that every time I spoke to them when the repair was needed. I believe this is the main problem for the installer and he therefore can use maintenance as an excuse. From what I have been told whether we changed the filter or not (and I know it should be changed every six months) should not be the issue but this issue is the improper brazing. There are apparently a number of reasons how the brazing could be done improperly and I cannot say if extra pressure on the joint lead to the weakened improperly brazed joint ultimately failing or it simply failed because it was brazed improperly in the first place. But the installer is saying not changing the filter lead to extra pressure on the joint and brazing which lead to the leak; we are saying even if there was extra pressure on the joint, the brazing done properly would never have leaked because it is the strongest component in the system and should be too strong to leak just under those circumstances.We contend that the installer failed to braze the pipe properly, either pressures or vibrations resulted in a leak or the leak occurred over time simply because the brazing failed and this fI have attached 2 pictures that were taken before the repair showing the "soap bubble test" and the other side of the pipe.I am attempting to get a consensus of opinion as to whether a properly brazed joint would fail under the circumstances described by the installer in a 2 year old system. Would the joint have failed at the time of installation or could it have held for a while and then failed as the system was run? Thank you

To quote the technician from this company when he diagnosed the leak: The pipe wasn't brazed properly when it was installed. Everybody makes mistakes.I also in September contacted another HVAC expert on JustAnswer about what would have caused the leak who stated the following: "as i stated the reason for it would have been it being brazed improperly. a properly brazed joint will never leak. properly done it is stronger than the pipe and all the other components in the system. it could be due to it not being cleaned, not hot enough when they brazed it too much purge when brazing or just not enough brazing rod used".I contacted the original installer who insists that there is no way to tell what caused the seal to fail or when it did and it could have been due to "vibrations" or "contaminants in the brazing". He also insists that if the leak had been present from the time of the installation, the system would have failed immediately or shown a leak during testing at the time of installation not 2 years later. The air conditioning system is run 3-4 months out of the year, the heating around 5 months.We forwarded a demand letter to the original installer asking them to pay for the repair. This is their reply: "The air filter installed in the HVAC system is not designed to operate for two years without causing restriction to airflow across the indoor coil. Operating the system during the heating season with a restricted air filter will cause significantly higher operating pressures and vibration in an HVAC system utilizing R410A refrigerant. This condition could have been easily avoided if the recommended maintenance intervals were followed."While we do say that the filter was not changed, if I am reading the above quoted JustAnswer HVAC expert correctly with the brazing being the strongest component in the system the leak would only have occurred if the the brazing was not done properly in the first place and whatever pressures and vibrations occurred in the system would not have by themselves caused the leak.We contend that the installer failed to braze the pipe properly, either pressures or vibrations resulted in a leak or the leak occurred over time simply because the brazing failed and this failure would have happened anyway due to improper brazing. We cannot say which scenario is correct but that improper brazing at the time of installation is the root cause of the leak.We believe the original installer is trying to make this a maintenance issue which it is not.I am looking for an an opinion the verify this or not before taking our claim further. Thank you.

I have spoken with another HVAC expert who has said also the pipe might not have been cleaned properly before being soldered. This or the solder could have been contaminated and vibrations over time could have lead the pipe to leak. I am looking for a neutral opinion about this situation

Just changed out the reversing valve in a goodman heat pump.

Just changed out the reversing valve in a goodman heat pump. charged with reclaimed R-22 from the unit and adjusted to factory charge of 220 oz. The unit suction is about 30 and liquid about 150 in cooling. Again the only thing I did was change out the reversing valve. It almost acts like its low on charge.JA: Did you double-check the thermostat's settings? And what about the filters?Customer: Thermostat settings are fine and it has an EAC that's good to goJA: Do you plan on doing the work yourself?Customer: I'm an HVAC contractor, this is something I did for a customerJA: Anything else we should know to help you best?Customer: The unit as a 50ft line set, I have tried to set the superheat by adjusting the TXV.
