Question about Heating & Cooling

2 Answers

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.

If 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 better for the heat to transfer to the outside and cut your costs of running the unit down.

No you can not do freon yourself you need to be cfc certified now,which means you can not buy freon.Best to have a service person come out.

    The indoor air handler coil is the coil your service people are referring to.
    It should be inspected and cleaned periodically.
    If dirty it will cause freeze up of the inside coil.
    A clean outdoor coilis important but does not cause a freeze up.

My goodman unit is freezing up. It is frozen from the line running out of my house than if u look down into unit, the freeze continues inside

Hello, the suction line will freeze either due to low airflow such as dirty air filter, blower wheel, evaporator coil or a weak blower motor. Also, a low refrigerant charge can cause the suction line to freeze up.

I have a Goodman A/C unit model number cpke 36-1a. My problem is that the fan in the house works along with the unit fan outside, but no cold air in the house. What do I need to check? thermostat is set at...

First check the filter to see if it is not completely clogged and make sure the
coil fins behind it are not frozen solid. If it is then shut off system or switch it over to
Heat to defrost the coils if you have a heat pump, then replace the filter.
Then check the outdoor unit to see if the large copper line coming to it is cold
(this means the compressor is running and not just the fan)
Also Make sure the thermostat is in "AUTO" and "COOL"
The last thing to check is to make sure the duct work to the return has not separated or
has not been torn open by animals (cats love to do this under mobile homes).
Sounds like a ductwork problem or plugged filter from what you describe. Hope this helps.

Cant keep cool

You need to check that tour filters are new. Then check that air is coming from the vents and is at least 15 degrees cooler than room temp. If no air coil is frozen, or blower motor and run cap are not working. If frozen than turn system to off and fan switch is on until you feel air through vents.
You'll need to make sure the outside unit is runing and the larger copper line is cold like a can soda. If it's cold but is freezing up, it needs to have a charge added. If its running but not cold and the fan is not running or the compressor isn't running it could have a blown capacitor. If its not running at all check. the circuit breakers and reset them. And a good idea to keep the outside unit washed with water,and that it is clear of weeds and stuff.

My air conditioner coils continue to freeze up. i

If the indoor coil is icing up, you are either low on freon, or the indoor coil is very dirty. This will cause it to ice even though you have replaced the filter. See if the suction line/large copper line has ice on it on the outdoor unit. If so, its low on charge or the indoor coil has plugged up and not getting enough air flow across it. Please keep me posted.

Bubbling water sound in AC. Water in the tray is cold. Unit continues to make a gurgling sound.

The gurgling sound is the liquid refrigerant going through the refrigeration copper lines , it's normal. And the water in the tray is condensation and is cold because is from the circulating air that gets cold going through the air handler(inside unit) You only has to keep the drain clean ,by pouring 1/2 cup of clorox every 3 or 4 months.

Not cooling house it stay on unless you turn the thermostat to 88 degrees

if the the outdoor unit is running and the larger of the two copper lines going into the unit from the house is not cold you are probably low on freon. if the line is iced up then you need to shut if off for 8 hrs and try again, make sure the filter is clean recheck the large copper tube again if its not cold your probably low on freon. if its not running at all outside check your breakers. there are a number of diffrent things that may be wrong and you probaly need a service company to look at it.

The copper line going from my outside unit up to the inside unit keeps freezing up. This on the outside of the house.

This sounds like you are low of refrigerant. Or you evaporator needs cleaning. Have it check out to see if you have a leak in the system

Goodman Model CK60-1C with White Rogers mercury tube thermostat

The contactor on the outside unit is sticking and must be replaced. The inside unit cycles off and the outside continues to run causing the refrigerant lines to freeze up.

Ac problems

Hello from KOOLBREEZES, this is a simle problem and easy to fix. You have 2-lines going to / from your outside unit. a SMALL COPPER -line and a LARGE COPPER line with insulations. The fat line is suppose to have moisture on it wheres it,s not insulated which tells you you have enough refrigerant gas comming back to he compressor but if its dry you,re low on freon and need a charge or the outside condenser is dirty and not getting rid of enough heat!
