Goodman air handler: condenser coils freeze over

Not sure how to post a HVAC question on this site, so I am sending it to you for posting.

i have a 25 year old Goodman Air Handler in which the condenser coils freeze over and hence has low out put. I have changed the filter and cleaned the coils back and front, yet it still is freezing over. My question is if my system requires replacement. Can I just replace the air handler or do I have to replace the newer and appears to be working great large AC unit located outside along with it. The Goodmen Air handler unit is a
R24-10 serial number 890301638.

thank you
Al

Welcome to the forums.
I started a new thread for you.


Typically when the evaporator coil freezes over it's one of two problems.....
1) low air flow.
2) low on refrigeration charge.

With a 25 year old air handler..... it may be time to consider changing the entire system. 25 years is a good run on a Goodman unit. If the system appears to be in physically good condition..... have the charge checked.

Thank you for posting it to a new thread, by saying you would replace the whole system, are you saying I would need/should replace the outside AC unit too. It is only about 10 years old and appears in good shape.

Thank you again
Al

I thought everything was 25 years old. A 10 year old condenser should still be good
So this is a 10 year old condenser with a 25 year old evaporator coil ?

Do you have a preferred HVAC tech ? Check with them too.

Hello Pete sorry I am no HVAC expect. The Air handler located in the house is a Goodman, I was under the impression that the coils which form a V on the bottom are called condenser coils. Theses coils inside the air handler are freezing up. I have cleaned them, and changed the filter, yet they still freeze up.
Outside side of the house is a large 10/15 year old Bryant (Coast guard) model number 561SJ024-A compressor which sits on my deck, and comes on with the air handler.

hope this makes sense.

thanks
Al

The coils outside are called condenser coils.
The coils in the air handler is the evaporator and sometimes called an A-coil.
The V is an upside down A.

Wow great sorry for any confusion, so it’s the A coil or evaporator that is freezing up, dispirit having cleaned them and changed the filter. do you think I might have to replace both the outside unit and the air handler, or just the air handler? Do you know about how much this will run me. I am in The 31328 zip code.

thanks again Al

A leak test has to be done - you can change the air handler with the leak is in the outdoor unit and end up with the same problem.

A new air handler can be matched with an old outdoor unit provided the metering device changed so it's correct. can do it even if the old unit is pre-2006, 10 seer, but probably not worth it over complete replacement. If the unit is a 13 seer, could be more worth it.

Hi Folks

getting the you need to replace everything due to the refrigerant being used, system is over 20 years old. So
i am being told that the best budget band is a company called Amerastar, when I looked up budget bands I can find only American Standard, I am being told that they are one in the same and both are manufactured by trane. Through?....
thanks all

Hello for those that care,

after searching the Web. I decided to go with a Trane HVAC system, it a 14 eer 2 1/2 ton system and includes all items and installation for 6000$. With 10 years parts and labor backing the item. This was due to the so so reviews on the Ameristar, the 10 years parts but only 1 year labor, I just could not see the 1800$ difference.

Thank you all for your help

Reviews in hvac don’t matter at all. They don’t take into account all the various problems hvac can have and the causes of them.
Brand as a whole doesn’t matter much. For the same reasons.

I haven't heard of Ameristar. I see it's an Ingersoll Rand company. They produce Trane products as well as others.

Be sure to register your new system for the extended warranty benefits. It can be done online.
You do it...... don't expect the installer to do it.

Thank you so much yes the installer told me to make sure I do it ASAP

thank you for all your help, I was able to talk HVAC (a little) to them and at least ask intelligent questions.

Ok next hurdle, extended warranties purchased through Trane, looks like I am getting the Trane 2-ton XR14
14 SEER split system heat pump and a Trane 2-ton TEM4 air handling unit. Sooo........

1) should I consider the extended warranty that would take effect after the Registered Limited Warranty expires.

2) should I consider a service contract that the installer is trying to sell me.

I am thinking maybe to the first one, and no to the second.

what do the experts think.....

thanks
