I had my A/C check up today and I got numbers from the tech.
Even though he said, I don't have a problem, I am cursious what the numbers mean. My unit is getting old and I kind of want to know if that will be good idea to replace my system before break-down. Since the quote I got from the A/C tech was more than I was gussing, I wish to use this system for at least another year. Mine is 14 years Goodman Model 4100 4ton.
Return air F: 78
Delivered F: 57
Outside Air : 87
Discharge: 240
Compressor Amp/rated 17/21
Condensor Amp/rated 19/1.3
Any help is appreciated.
It's 14 years old. Its about that time to think about replacing. The unit might run another 5 years or 5 days. Nobody can tell. Hell, you really can't tell on a new one anymore. You can either bite the bullet and install a new one now or later. It's up to you. You might install a new one and the compressor die in a year also, chances are slim, but always possible.
If it is 14 years old and still giving good service, I'd start budgeting to replace it, but I wouldn't be worried about doing it tomorrow. Start saving and preparing today and it just might run until you have the money to replace it in the bank. I have a Goodman heatpump installed in 1991 and a air conditioner with a furnace installed in 1992 and both are running right now, but one can only guess at how much longer they are going to run.
I'm not a pro, but when I had my unit checked, I was told that my compressor was amping high (and it actually went bad shortly thereafter). I believe he said that the compressor amperage should be 2/3 of the maximum under most circumstances. Is this right? If so, then it sounds like his compressor is drawing a lot of power, likely due to old age? He did say that it didn't mean the compressor was going to die soon necessary.
not to scare you, because it may be written down wrong, but it appears your condenser fan motor might be slightly over amping, maybe weak capacitor or failing bearings, did he mention this? , and yes I do know there should be a period between the 1 and 9
yunrowlett, You have to understand, those that do this type of work hear this all the time, "Oh, I plan to replace it next year" , and it seems like few do. Given the age of the system you would be wise to do as you said, and replace it before you have a failure, and you just have to grab the first available company and equipment, because you are tired of sitting in a hot house. I think if you talk to a knowledgable technician about the equipment currently being offered, you will be pleasantly suprised about the features and efficiencies available. Start looking, and commit to a time frame. Good luck.
that's not how the nameplate works
you may be confusing the min/max circuit ampacity
oh, ya on a normal residential system, the controls are fed from the x-former in the airhandler
the nameplate will list
compressor amp draw
condenser motor amp draw
min. circuit ampacity
max. circuit ampacity
voltage
phase
hertz
and a few other tid bits
but there is no listing on the nameplate for the sum of the added compressor and condenser amps!

I know I just may not be familiar with the product, but what is a Goodman 4100?
Training is important!
Practical Training is a must!
