Question about Air Conditioners

1 Answer

My goodman heat pump has frozen up 3-4 times already this summer. It is a dual system 10 seer (i believe are the terms). Every time someone comes out they can't figure it out because the system is running fine by the time that they come. Two years ago the blower or activator was replaced (maybe the replacement part isn't so good?) The unit is 9 years old. Last year a guy charged it and about a month ago when it was checked the freon was only a little low. I'm SO tired of this issue. Any ideas?

After system has been running 10-15 minutes, the discharge air temp should be 18-22 degrees colder than the air being sucked in. If the air is more than 22 degrees colder then the problem is with air flow. Check filters, blower speed, make sure all vents are open, is indoor coil clean. If the discharge temperature is less than 18 colder, then the problem is with the refrigerant portion of the system (low charge, improper flow control of freon into coil) the key is if you have an orfice or a TXV (Thermal Expansion Valve) to control the flow of refrigerant into the coil. TXV's are known to fail with intermittant problems, however, most 10 seer systems do not use a TXV, they use and orfice which could have debris in it affecting the flow of freon. Hope this helps. When you rate my solution, please keep in mind that I am a technician that normally diagnoses equipment by checking it out in person. I do the best that I can with the information that you provide me on Fix-Ya.

Thank You,

Yes there is a way. First You need to see if the outdoor unit has a time delay on it.It would be connected to the contactor and the low voltage wires. If there is not one then there is a problem with your thermostat. If you have the thermostat manual, check to see if there is way to change from the 3 minutes to none. I hope this helps you.

I HAVE A GOODMAN MODEL CKL36-1D I'M TRYING TO FIND OUT THE SEER RATING ON THIS MODEL.CAN ANYONE HELP?


Your going to need to know the age of the unit. If its less than 5 years old, its most likely a 13 SEER. If its anything more than 5 years old, its most likely a 10 SEER. If its anything over 10 years old, its most likely an 8 or 6 SEER.

Remember, that a unit will loose an average of 1-2 SEER for every full year of operation. This is just due to age, wear and tear, and usage.



So, if its a 10 SEER unit that is 7 years old, you could say that it is about as efficient as something in the 4-6 SEER range.

Heil Heat pump model # NHP218AKC2, I need the specs to replace an old unit in the other side of my duplex


I can help you on part of your question, the system that you listed above is a 1.5 ton unit, if I had the serial number I could give you the age of the unit. If it is a late 1990 model, then it is probably a 10 SEER unit, maybe a 12 SEER, if it is older than 1994 it will be a 8 to 10 SEER, but due to new federal rules, all new heat pump or air conditioners are at least 13 SEER. If you just replace the outdoor unit and leave the coil indoors, it will be mismatched and cause the unit to be less effeciant, and some problem in adjusting the Freon levels.
Ideal is to change the outdoor unit and indoor coil.
I hope this helps, I am new to this site, so I am still trying to get to the point, and yet give you the details that you need.
Sincerely,
Paul Gibson
