SOURCE: outside makes loud noise

I would take a very close look at every solder joint there is between the inside unit and the outside. If you observe oil at any point it indicates a leak at that point. That is an expensive price for what you say was done. Check your invoice for the amount of refrigerant they or he added to the system. Compare it with the amount stated on the outside unit nameplate. Check for frost on the suction (big line) by the outside unit. If there is frost your coil is frozen up. If this is the case turn the fan on and the cooling off. Allow it to run in this manor for about an hour to defrost the A coil. Then return to the cooling mode.

SOURCE: house is not cooling but it is blowing 60 degree

check to see if there is a 20 degree split between supply and return air. If its less than 20 than it might be low on charge.

SOURCE: UNIT IS ONLY 4 YEARS OLD AND IS ON ITS SECOND

what is your suction pressure? 23 degrees is to high on your superheat should be around 10-15 degrees. subcooling a little high. do you have any airflow problems like a dirty condenser or dirty squirrel cage or dirty evapartor? subcooling should be between 10-20 degrees. what is the freon you are using in the unit? what is your delta T? That is the temperature coming out of the supply and return. subtract both of them and you will arrive at your delta t and it should be around 18 to 20 degree difference.

Make sure the indoor filters are clean. The outside unit will continue to run until the indoor reaches the temperature you have selected. Dirty filters can throw the temperature out. Its common for outdoor units to freeze up when on heating mode if the ambient air temperature is below 5 degrees Celcius.. The machine should however, defrost itself. There could be a problem with one of the pipe or air sensors on the outdoor unit.

Tip

Why your unit is freezing up.


To understand why your AC or heat pump is freezing up, it helps to know how your system works.

There are 7 major parts to an AC system, 9 with a heat pump.

1 - Condenser/heat pump (The outdoor unit)
2 - Air Handler (the indoor unit unless the system is a package unit, then all is outside in one system. The air handler is usually found under the home, in an attic, or in a closet.)

In the condenser are the following major parts.

3 - Compressor
4 - Condenser coil
5 - Condenser fan
6 - (HPs only) reversing valve

In the air handler are the following major parts.

7 - Blower motor
8 - Evaporator coil
9 - (HPs only) electric heat strips

Some systems known as "dual fuel systems" use another heat source in place of the heat strips, usually a gas furnace. I will address gas furnaces in another post.

When an air conditioner is operating properly several things are taking place.

1 - The compressor is compressing or "pumping" refrigerant through the system.

2 - through changes in pressure, the refrigerant makes the evaporator coil get very cold, and the condenser coil gets very hot.

3 - The blower motor/fan circulates air across the evaporator coils, as the room temperature air (Also known as "indoor ambient") goes through the cold coil, it exits, cooled approximately 15 to 20 degrees cooler than when it entered. (In a ducted system, the blower is also the fan that circulates the air throughout the home.)

4 - The condenser fan circulates air across the condenser coils. As the outdoor air goes through the condenser coil, it removes heat from the coils that are very hot. This in turn removes heat from the refrigerant so it can run its cycle again, and through pressure changes, cool the evap coil.

5 - With a heat pump, the reversing valve reverses the flow of refrigerant in the condenser and evaporator coils.
In AC mode, the evaporator coils get cold, and the condenser coils get hot. But in heat mode, the evaporator gets very hot, and the condenser very cold.

Now, whichever coil is getting cold will freeze up if there is inadequate air flow across the coil, as the refrigerant in it is far below freezing, and there is not enough airflow to keep the humidity in the air from freezing on the coil.

Things that can cause poor airflow are,

1 - Dirty/clogged coils
2 - dirty/clogged filter (will only effect evaporator coil)
3 - Closed/blocked vents (will only effect evaporator coil)
4 - Malfunctioning or dirty fan

Low refrigerant will also cause a coil to freeze up, reduce efficiency and cause the system to run for long periods of time. Not to mention, shortening the life of the unit.

With a heat pump, in heat mode only, the condenser (outdoor) coil will routinely begin to freeze up in cold temperatures. This is due to the fact that the refrigerant is below freezing, and the cold outdoor ambient temp is not warm enough to keep the condensation in the air from freezing on the coil.

Note, a properly working AC should never freeze up.

A heat pump is equipped with defrost controls to prevent ice buildup.
Some are controlled by timers, some by temp.

When a HP is going into defrost mode, the condenser fan shuts down, the reversing valve reverses the flow of refrigerant and the once cold condenser coil now gets very hot, defrosting the coil. (Many people have said this process sounds like the unit is coming apart, or about to explode and are frightened by the "smoke" which is really just steam from melting ice that comes off the unit.)

During defrost mode, the secondary or "auxiliary" heat comes on to ensure that you are still getting warm air from the vents. (Again, this can be electric heat strips or a dual fuel system)

If you are experiencing cold air from the vents during defrost, that means your auxiliary heat is malfunctioning.

The auxiliary heat is used for three purposes.

1 - during defrost mode to maintain warm airflow (automatic)
2 - when the HP cannot maintain the set temp due to extreme outdoor temps. It comes on when the indoor temp drops several degrees below the set temp on the thermostat (automatic)
3 - For emergency heat source when the HP is not working. (Manual)

To recap....

Iced up coils?

Poor airflow
low refrigerant
Malfunctioning fan
failing defrost system


There are two things that can be done in a pinch to help de-ice frozen coils. This may get you by until the repairman can get there, or you can fix the system if you are a do-it-yourselfer.

HPs frozen outdoor coil in heat mode, not going into defrost?

Cover most of the vents, and turn the system onto cooling mode until the outdoor coil is thawed. then uncover vents and return to heat, or emergency heat. (this usually takes 15 min or less)

Frozen coils in AC mode with a heat pump?
Turn the system to heat with the thermostat on just high enough to get the system to come on. (again, usually takes 15 min or less to thaw.)

AC only, with frozen evap coils? (this can sometimes be seen frozen all the way outside to the compressor on the copper lines.)

Turn the system off, and the fan switch from "auto" to on".
This will usually defrost the coils within 1 to 2 hours.
(If your system has the furnace in line before the evap coil, turn the system to heat, and the furnace will defrost the coil within minutes.)

Coils are freezing in the room air conditioner


Hello my name is Heath it will be my pleasure to assist you. First thing to do is turn the unit off and check the filter then if the filter is okay check to see if the blower comes on when you put the fan switch on the thermostat from auto to on. If the blower isn't coming on then there could be a problem with the blower motor. If the motor is running then turn the system to cool and turn the setting down to where the air should be on. Then check the outside unit and be sure the outside unit is running if the outside unit is not running go to the house panel box and check the breaker to see if any of them are tripped or off. If there off turn them on and check the outside unit again. If all is running and you get no air flow through the vents then the coil could be frozen. If the unit is frozen turn the thermostat to off and leave the indoor blower on by leaving the fan switch in the on position for a couple hours till it thaws. If the unit froze up then there could be a problem with the a/c system most likely low on refrigerant as a result of a leak. I would have it leak tested and repaired if this is the case.

Air conditioner blows cold air, but will not cool a 1300 sq. ft. home past 75. Coils do not appear frozen and drain tube is clear.


If you have serviced the air conditioner such as cleaning the condenser coil, changing the filter, cleaning the evaporator coil and checking the refrigerant, you have done about all you can do. Most air conditioners can cool up to a 30 degree differential. If its 100 outside most units will be able to maintain approx. 70 degrees. It also depends on how tight the home construction is as well. Find out if you have ample enough insulation in the attic. This always makes a good difference. Also, is there insulation in the walls and how tight are the windows? In the middle of summer all depending what the weather is like, most air cond's are running at their peak. If you have not cleaned the outdoor condenser coil with a hose and a sprayer, you might do so. Turn the power to the unit off first. Also, have the refrigerant checked. Hope this helps.

It is freezing inside, and it is not cooling properly


Welcome to FixYa,
Check the Following
Is your filter clean? Look and the evaporator in the inside unit. Is it frosted up? Do you have condensation water in the pan? Go to the outside unit and feel the air coming out of the fan. Is it warm? Now feel the 2 copper pipes coming out of the unit. Is the small one warm or hot? Is the larger one cool ? Is there moisture on it?
Air conditioner runs but doesn't cool at all
If the airflow is good and the air coming out is not cold, your home air conditioning problem may be a temporary problem - your coils may have frozen. Turn the unit off for an hour to let them thaw, then try again. If cold air is now present, freezing coils were the problem; if the problem recurs soon after turning on, you may need to replace the coils. Again, call a pro. If you have ceiling vents in upstairs rooms and the air flowing from them is consistently warm, you probably have leaky or poorly insulated ductwork in your attic. See my Attic ceiling insulation page for more information on insulating ductwork that runs through attics.
Another likely home air conditioning problem if you have good airflow but no cooling is that thebreaker to the outside unit is shut off, which, depending on the installation, can either cause the air conditioning system to not run at all, or to appear to be running but not provide any cooling. If you can hear the compressor fan running outside, the breaker is on, but if the outside unit is silent the outside breaker may be off. If switching it on does not solve the problem, look for the high pressure cut outon the condenser and try resetting that.

My heat pump is frozen up today and it is 60 degrees outside and I have my heat set to 66 degrees. Is this normal?


You post is not clear as to where the freeze-up is occurring. I'm going to assume the outdoor unit is frozen up.
Heat Pumps don't generally freeze up at 60 degrees. If the ice around the unit has an uneven pattern (for example a thick spot around the center or at the very bottom) could indicate a low refrigerant charge. If the ice is even throughout, it may be one of the following:
*Sticking Contactor*.....turn the system off at your thermostat and check to make sure the unit outside shut off. If it doesn't turn off, it is likely to be the contactor.
*Failed Defrost Thermostat*.....if the defrost thermostat fails "open", the system will never go into defrost.
*Failed Defrost Control Board*......this could also prevent the system from going into defrost
*Failed Reversing Valve*........put your system in COOL mode and check to see if it will blow cold air inside approx 16 - 22 degF lower than room temperature.
*Failed/Failing Condensor Fan Motor*.......ensure the condenser fan motor is running during heat and cool modes. The condensor fan motor will not run in OFF/Satisfied Mode or in Defrost Mode.
I hope this helps. Good Luck! :-)

Outside compressor is frozen - shut the fan down. Will it defrost and be operational


Is the unit a heat pump? Did this unit freeze up during A/C mode? Only if it was due to mild weather and thermostat turned down to low., past 68 degrees. Filter could be dirty or coil dirty or low freon charge.

Why isn't my Sunbeam Window A/C blowing hard on high?


If the air doesn't seem cool enough it is necessary to use a thermometer to check the difference in temperature between the air going into the unit and the air being blown into the room. Ideally, the temperature difference should be more than 15 degrees. For example, if the temperature going into the air conditioner is 80 degrees, the temperature coming out of the unit should be at least 65 degrees or less. If the difference is 15 degrees or more there is probably no cause for concern. If the temperature difference is less than 15 degrees you should check the following:

  • Air damper

Check to make sure the air damper is closed. If it's open, it will bring in outside air and reduce the efficiency of the unit.

  • Back cover

During the winter season many people cover their air conditioners to protect the unit from the weather. In the spring or summer they will sometimes forget to remove the cover. If your unit has a cover on the outside portion of the air conditioner remove the cover first.

  • Condensing coils

The condensing coils will always be on the "warm" side of the air conditioner. That is, on the side that faces outside of the room to be cooled. Air is drawn into the back of the air conditioner on the sides through vent slots and is blown directly out through the condenser coils. If the coils get clogged with lint, dust and dirt the cooling system cannot provide the cooling necessary. To clean the coils it will be necessary to remove the entire cover of the air conditioner or pull it out of the wall to gain access to the coils. They can be cleaned by blowing compressed air at them or by using a soft bristle brush to wipe the dirt off. It is important to also clean any dirt or lint build-up in the bottom of the air conditioner so the condensate water will be picked up by the condensing fan slinger properly.

My AC unit keeps freezing up on the copper lines going into the house from the outside unit. It also freezes up on the inside lines and the air is not cooling my home down.


Operate your air conditioner with the fan in the on position. But first turn the fan on, turn the temp up or shut the cooling off. Your coil is more than likely frozen over. At night when outside temperature drops the refrigerant pressure and temperature in the system also drops. This action can cause icing of the cooling coil, with the fan in automatic everything shuts down at the end of a cooling cycle. Thus no air movement to melt ice on previous cooling cycle.
