Having problems with your Air Conditioners ?

Properly Insulated refrigerant lines of aircond are sweating outside and moisture or dew formed along the surface of foam insulation. what will be the possible root cause?


Answers :

The root cause is the temp of the lines are below the Dew Point of the surrounding ambient air. Improper charge, low load/ air flow, wrong insulation, improper superheat, are all items that can cause this condition. You may have to look further into whats going on.

I have an American Sandard 15 Sheer 4 ton unit in the attic in South Louisiana. The a/c drain line from the unit is sweating all the way to the riser vent and down the riser into my wall. It appears that the unit blows so much air through the line and it blows cold air through the p-trap which is causing the condensation. Any solutions or suggestions to stop the condensation from forming on the line? We have already put to 3/4'' clean out vents to reduce the air flow from the unit. Any help woul


First, air should not be blowing through the trap. The trap is there to isolate the air and to make sure condensate flow is proper. Start by increasing the depth of the trap. The condensate is going to be relatively cold, in the range of 58 degere ... American Standard Air Conditioners

I have a water leak that seems to be coming from my furnace unit. No water lines above unit. Seeing water dripping down inside of blower area along unit's wall. What may be causing the water?

I'm getting condensation leakage from the vents in the roof. This is on a ducted system, and it's leaking from the two vents closest to the main blower unit up in the ceiling. It's very high humidity here lately, and the leak usually starts around mid afternoon. Up in the ceiling you can see the drops of condensation forming on the under side of the main blower unit, and also all along the large insulated air ducts. I've got the thermostat set to 24deg, it's usually 30 - 34 deg outside. When I

Are walls suppose to have insulation? on a 2 story building,one side of building walls have a lot of moisture inside,and it's very humid, wall seems to swet, and it feels a little wet, can this be caused by not having insulation? or is it caused by a different reson? thanks.


It could be caused by no insulation if it's cold outside and warm and humid inside. If you have any electrical sockets on that wall you can cut the power and remove the socket cover and see if you can see any insulation. Make sure there is not water ... Air Conditioners

I have a GMP 075/3, serial #9711 816 586 installed in 1998. The control panel flat type fuse blows periodically. What is the correct fuse amp rating -- 3 or 5 possibly? What are the possible causes? The local techs don't seem to know what might be causing the failure. Usually it seems to be during start-up after an extended downtime.


I tried to run down a parts list on the net, to no avail. My suggestion would be to contact Goodman support to find out the fuse rating.\015\012There's a chance a local repair shop may have the service manuals.\015\012Here's Goodman's s ... Goodman Air Conditioners

The unit constantly freezes up. Suction is at 85, liquid is at 285, suction line temp is 52. Ambient 85, while inside is at 85-88. Only 1-2 degrees of superheat. Taking refrigerant out lowers line temp (backwards), while adding it raises line temp (backwards). Airflow is not bad but not great. Possible blocked metering device or evaporator?


Has anyone added refrigerant? If there was a blockage I would think the suction pressure would be lower. Are you sure it isn't just overcharged. If you take the ambient and add 20F that would give you a condensing temperature of 105 which gives you a ... Intertherm P3RA-030K Air Conditioner

Our Goodman inside unit has an accumulation of ice on the Larger of the two lines from the outside unit. A thermometer in the grill in the ceiling indicates that the temp at the grill is 76.4 F even with the thermostat set at 73 F.

I have a thru-wall unit that is draining out of the back and cooling just fine. My problem is the hole in which the ac goes thru. There seems to be some condensation on the bottom of the unit that drips down onto the board below(would be the window sill if I had taken it thru the window).

Model GSC130481AG, S# 0808548576 The common wire to the compressor rubbed through the wire insulation and melted a hole in the discharge line from the compressor. Upon loosing all of the refrigerant the compressor ran hot a warped the valves. I repaired the leak and replace the compressor and liquid line filter drier. Upon start up the system would take little refrigerant. The suction pressure went into a vacuum with a 115# head pressure. What is wrong here?


You have a restriction in the system. Probably in the TXV or orifice in the A/H.The burn out sent trash/fragments through the system. I would open the sytem and blow nitrogen through, then pull a deep vacuum.You may need to install a low ... Goodman Air Conditioners

Heat does not come on. Furnace light blinks 3 times, indicating faulty pressure switch. I jumped the pressure switch, which caused the ignition filament to light up. However, it quickly shut off again. No gas comes out so the blower never starts up. Have checked the lines, they appear to be clear. Furnace is only about 6 years old. Any idea what is causing this and how to fix it?

I have a Bryant split unit. After incurring some water damage that I assumed was from the overflow pan (the damage came from a poorly insulated elbow in the duct that was sweating) I opened the unit and found the condesate pan dry but the interior was completly saturated.

I have a Coleman 5T 13 Seer Heat Pump. When the unit is running there is a lot of vibration (outside unit) and I hear a tinny sound (possibly like the fan hitting something). This seems to be worse during the hottest part of the day.

I have a CAPF Goodman Coil that apparently needs cleaned due to lack of circulation. The repair company wants 1000 dollars. Is there a way to clean the coil on your own and there is warning label that references PSI. Is iit possible to clean the coil without breaking the lines? Is the PSI warning in reference to the lines or the removing of the panel?


I think you are referring to the Evaporator Coil on top of your furnace. If so, the PSI warning is due to the pressure inside the copper lines. The newer refrigerants can run over 400 PSI with the unit running. This coil can easily be cleaned by you ... Air Conditioners
