We had a new air conditioning/heat pump system installed in

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 the filter 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 seal the joint properly when the unit was first installed which lead to the leak. I contacted the 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 solder". He also insists that if the leak had been present from the time of the installation, the system would have failed immediately not 2 years later. The air conditioning system is run 3-4 months out of the year .Is there any way with the system being used 3-4 months under normal conditions that this leak could happen spontaneously without the joint not being sealed properly during installation? 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.

We have a 9 year old Goodman heat pump system in our

Hi,we have a 9 year old Goodman heat pump system in our residential home 0f about 2800 sq ft and have been told that the coils are leaking and should be replaced or a complete new system put in. We live in the Southeast. The new system that he suggested is a "Ruud Inverter" heat pump system. Please help me with this: 1. What is a Ruud Inverter system? Do all Ruud systems have this as part of current technology or is it something you install extra to a system? 2. If we get a new system put in what kind of very efficient and reliable system is recommended. Brand name suggestions are appreciated. 3. What kind of reasonable cost might we expect for purchase and installation of a better system. 4. Any other thoughts appreciated. Thanks much.

I have a goodman heat pump. The fan motor in the condenser

I have a goodman heat pump. The fan motor in the condenser unit comes on but there is am intermittent hum. When it hums, the fan motor slows. The hum only lasts about 3 seconds, then motor speeds up. Unit was checked 6 months ago and was told that fan motor was starting to go as they could see oil on the fan blades. I have a new motor to replace it, but wondering if that is the problem or is it capacitor?
