I have a 11 year old, 2.5 ton trane package unit at my home. the tech added refrig 3 weeks ago because the unit was freezing up. coils still freezing up. air coming through vents only getting down to 70f. tech came back last friday. trane said there must be something (trash) in lines. tech evacuated system, purged lines and recharged. air from vent only gets down to 74f now. compressor seems to be working fine. i just thawed coils with water. they were frozen completely.


After the tech added refrigerant, did the coil freeze up after he left, or was it a day or more before it started freezing again and are you running the unit on high cool? You either have a leak, which would usually take some time to leak out enough ... Air Conditioners

I have an intertherm AC unit (model E2EB-015HA) and the inside unit is leaking and damaging my floor. We discovered this last summer and assumed it was a combination of condensation from the unit and freezing up. As it did freeze up and we caught it rather late. I did a good cleaning, filter replacment, and checked the line running out of the water-pan and it was not clogged and water was flowing well. I fixed some floor damage in my hallway and kept a close eye on the unit. This summer it has s

My daughter has a Bryant AC Model number 563AN048-A where the outside coils are freezing up. The repairman has been out twice and has cleaned the coils on the inside and outside units and has checked the coolant levels that he says are ok. Currently, if they remove the cold air return filter, air circulation is increased slightly and in doing so, the outside coil is not freezing. Can't run the system without a filter as the internal coil will clog. Any suggestions would be appreciated. Assoc


Hi, this is a 4 ton unit, Bryant are top of the line, I believe so as I have worked on them for so many years. They were Day & night, just a name change is all. Here is what sounds like your problem is, or is your problem. Did the tech check the ... Air Conditioners

Have a coleman mach unit that never cools correctly. If you run on low with thermostat halfway down it will keep running. If you run it on high, it acts like the coil is freezing up and barely blows air. I assume it is low on charge. Is there no way to add a charge? We have had our rv only 2 years and they replaced the unit once already.


It may also be an obstruction in the ducting. When the forced air is restricted somewhere, it will freeze the coils, and compressor shuts down, until frost is gone, then starts back up and will repeat that all day. I'm thinking that the restriction d ... Dometic Rooftop RV Air Conditioner

My American Std/Trane heat pump model#WCX036A100BB keeps freezing up at the internal coils & compressor tubes. I had someone out the other day, who topped it off with R22. It wasn't that low, according to him. I have cleaned both the inner coils and the external. It is a package unit, so essentially both are external. But I am referring to the coils that the return air goes through (same compartment as the blower fan). It still blows cold, then freezes after a couple hours of running. Chec

The coil in my byrant furance is freezeing up , my ac has been running for hours and i noticed that the house was not cooling down. when i checked the furance i noticed ice on the outside of the coil above the furance. my outside unit is running ok.


It sounds like your evaporator coil is freezing. This happens when you do not have enough air flowing through the evaporator to keep the humidity in the air from freezing on the evaporator. Turn off the A/C to let the evaporator coil thaw. Check your ... Air Conditioners

Central air unit problem.......It starts out blowing cold then will only blow room temp air after some time. I don't see anything freezing up..Filter is clear. The unit outside is not clogged up. The copper line running in is getting very hot..


Check your outside unit to see if fan is running. If it is running check to see if air is blowing out if not you have a bad capacitor. Some times if a capacitor shorts out the fan will run backwards and the line will get very hot same as if the fan i ... Air Conditioners

I have a Goodman home A/C unit and the copper line coming into the house freezes up. The unit continues to run with no cold air. I was told it is either dirty or low on Freon. Are they correct? If it is low on Freon is this something that I can do myself. Thanks.


HelloIf you have ice on bigger copper line and no cooling then the unit is low in freon.As far as cleaning it,you should clean the outside condenser in the spring.Use some simple green and a hose to clean the coils,this will make it ... Air Conditioners

I have a Goodman condensing unit that freezes up occasionally during low ambient weather (20 F). Model # ssz160361ac with matching new air handler. I have adjusted the defrost time from 90 to 30min. This I thought took care of it but it happen again when the temp dropped really low. When watching, it will go into defrost and clear the coil. But this last time the coil did not clear when I woke up this morning and the system was calling for heat but not running the heatpump.


It is not freezing up because of the temperature, but because of ice being formed in inside. Either by a blocked condensation duct, or snow due to previous storm. ... Goodman Air Conditioners

I have a Bryant 561c central air unit. I replaced the capacitor, which was obviously bad. I also replaced the circuit control board with the relay insode, since one of the transistors was blackened.

The refrigerant line in the wall of my guest bathroom running from the Lennox A/c condensor outside makes a loud buzzing noise when it is running. The supervisor of installation of the original installation company examined the unit thoroughly outside and up in the crawl space where the line runs and says the loud, irritating noise is normal. He claims that his unit makes the same noise in his house and that I am hearing the normal noise of the outside unit running inside the house. He explained


It may just be a loud condensor, otherwise, it could be a vibration from the unit housing and the noise carries. You could always replace the relay and see if it helps any. Also check unit pressure with pressure guage to make sure it is not over pump ... Air Conditioners

With unit set to air conditioning, the controller board will not turn on the blower motor and the cooling coil freezes up. McNutt tells me the controller board is kaput and they want $550 for it. In the meantime they have jumpered over the controller so the blower runs constantly. Was hoping someone might be able to tell me where to get it for less.

My house is 1308sq foot living. My outside unit is about 4yrs old, the air handler is about 3yrs old. It cools decent but when I have family over (appx 10 people or more) the a/c keeps running and never cools down. Is there anything I should be doing like cleaning the coils every so often in the handler? Or clean out the lines where the water drains? I change the filter usually monthly..


Yes, change the filter every month or so, more if you have pets. Spend the extra dollars and get filters you cannot see through! If you can see through it it is worthless to start with. You should see if it gets dirty and needs changing. You may have ... Goodman CLQ36AR49 Air Conditioner

Could my coils be freezing up, and what do I need to do to resolve this problem?
