Question about Heating & Cooling

1 Answer

I have a Goodman AR61 and it is not cooling. I have recently had the system recharged, because I thought it may have been low. When the service guy came out he said I had plenty of charge in the unit, but he went ahead and topped it off to be safe. He told me that the unit was not circulating because of a frozen coil. Which happens because it may be dity. I told him time were a little tight how much would it be to clean it out. He said give it awhile until it melted and I could clean it myself. Well I did this and it worked for about a week. Now it is not working again. Any ideas on what it may be? If I had to guess, I would say it had something to do with a relay or pump of some sort.

    The tech had did all of that. Plus the unit had already been off for a good 8 to 9 hours in the AZ heat. I'm guessing and hoping that that was plenty of time. Is there any other ideas on what it could be. Everything runs but the compressor doesn't stay on long enough to cool the house. It staying at about 85 inside.

Coils get frozen when freon is low or a restriction on a capillary.The reason he got good readings was because the unit evaporator was iced up. He should have run the system on fan only to melt all the ice and get true readings before charging it.

    Make sure the condenser coil is cleaned at twice a year. That's the unit outside. It can be cleaned with a water hose with a pressure nozzle on it. Grass clippings and other debris will accumulate over time and make the compressor work too hard and eventually shut off until it has cooled down. Sorry for taking long to answer, I was at work until 5pm central.

Goodman AC unit recently service but don't believe the filter I am using is the issue or what the tech did actually fixed my issue. Details below.


Setting the air handler to high speed will draw more current and this will result in an increase in electricity consumption.

My ac keeps freezing up


You need to have the unit serviced . The freeze-up can be caused by blower failure while system is running or not coming on at the call for cool. Goodman has a thermal relay that bring the fan on after a short delay. Your evaporator coil may need to cleaned. You can have a low refrigerant charge. A lot of companies offer a low cost service check. We come out and do a thorough check of your system and can identify the source of your issues and sometimes freeze-ups can be caused by something as simple as a dirty air filter. I would start there first.

I have a goodman central air unit. It was not cooling had service man out the first one said the compressor. So he was sending someone out to replace the compressor. That guy said it was not the...


Calll him back out. It sounds like the air cond. is losing refrigerant rather quickly. When the refrig. leaks off, the compressor over heats and kicks off on internal overload. The first guy probably didn't see that, but the second guy caught it, but didn't check to see where the refrigerant leaked off. Call him back they should warranty the refrigerant if it is all leaked off again

It's likely low on refrigerant and freezing...turn it off, coil thaws , cools for a short time and freezes up again. Chances are the leak or leaks are at the flares where the copper connects to the unit. Need leaks repaired and systems recharged.

I have a dometic duo therm roof ac unit that is low on freon - can the system be recharged?


It is a closed system, (ends are soldered) that said, a heating and cooling guy may be able to install fill valves and re-charge for you, but make sure you get a quote ahead of time. How old is the unit? Not normal for them to need re-charge, and I've seen them work good for 15 years, if maintained properly. Has it been completely cleaned recently?

Goodman Condensor cplj48-1 Air handler Modle


It sounds undercharged (needs more refrigerant). Based on the conditions in your post and assuming the indoor humidity is within 20-70% range, your target superheat should be 10degF. Your superheat (assuming you have an R22 system) is far too high. The pressures are not indicating a restriction; therefore, I have to conclude you have a low charge. A low charge will cause a gurgling sound due to the refrigerant in the liquid line is vaporizing prior to reaching the Cap tube at the Air Handler.

I hope you find this information helpful to you moving forward. :-)

No it should not. If their is a leak and it can be reached the coil should be repairable. Replacing it will require a pro to replace it and recharge system. Not a user friendly item. Also may need a line drier and a vacuum pulled on system. You need a license to handle R22 and this may be an R 410a system which requires special gauges. But I would try to go back to the installer and or Goodman about the leak.

Goodman a/c unit


The pressure depends greatly on the ambient temperature outside. There are two methods I use for charging a system

1. Is calculating the superheat
2. Is calculating the sub cooling.

Any good service technician will use these methods.
