Question about Heating & Cooling

1 Answer

A/C does not blow cold air. It has frosting built on the pipe that connects to the a/c unit outside. There is some water built up where the filter sits. I turnd off the a/c for a full day, the frost melted, filter is very clean, and nothing on the inside seems abnormal. I started the a/c again after 1-day but the frost started to built up again and no cold air was blowing. (it blew cold for a few minutes only). I don't know what the problem can be. Please let me know if you have any ideas to make it function correctly again. Thank you, Shelly

    Thank you for your answer. I have an appointment with a technician to come and take a look at it. Hopefully he can tell me how did the AC ran low in freon since it is only 3 years old and it has always been kept clean.

    Thank you again for your honest efforet and help. It is greatly appreciated.

Most likely you are low on freon. Your air conditioner uses a coil that gets cold when the freon passes through it to produce your cooling. The temperature of the freon inside the coil is directly controlled by the pressure of the freon. When the system is low on freon, it causes the coil to become to cold and then instead of sweating it freezes. You will need an a/c technician to reslove the problem for you as the task requires tools and equipment that you most likely don't have.

Thank you,

Which is cold water connection on the boiler

Incoming cold water usually connects to nipple marked with C, and/or the nipple that feeds into water filter (if unit has built in filter)
If unit has shut-off valve, then shut off is located on cold line.
If unit is operable, then turn on hot water and see which pipe gets hot ... and then cold is other pipe.
read your product manual.
Search your brand and model on internet to locate product manual.
Otherwise re-post question and include brand and model number so product manual can be located and information can seen first-hand.

Blow air running compressor not running

Your air compressor is dead or the refrigerant has leaked out. Wait!!! Don't give up yet. This very same situation happened to me. I had air blowing(not cold at all) but the outside A/C compressor was not running. Check your inside unit which is either in a closet or in your attic. There is a water pan underneath it. If it is full of water, it has activated a floating shut-off switch that is wired directly to your outside Compressor. You must remove the water. the best way is with a large wet-dry vac. Then make sure the drainage pipe is properly connected and is not clogged. You can probably fix that by sucking out the drain pipe with your vacuum. Once the water is gone, your floating shut-off switch will re- activate your Air Conditioner. Kind of like the floating ball in your toilet. You may sweat a lot, but you will save yourself a service call and some big bucks. Good Luck!!!

I have a Lennex heat pump unit which was installed in 2008. Our area (Savannah, GA) has experienced some abnormal cold temps lately. Yesterday, I noticed the outside of the unit had frost on the unit. ...

Heat pumps are the same as an A/C unit only it works in reverse. Instead of blowing cold air inside and hot air outside it blows hot air inside and cold air outside. The heat being blown inside is extracted form the cold air outside. Its called Latent heat Latin for hidden. Believe it or not even though its 20 degrees outside there is still heat in the air. Example if you want to drop the temperature of a freezer from 20 to 10 degrees you have to remove heat .I know your getting unusal weather and that is the problem. Heat pumps can only work no lower then around 20 degrees outside.Heat pumps are never used above the freeze line. With your unusal temperatures thats basically where you are now. Ride it out. When your temps rise a little your be fine. Im in Chicago.

Leaking air conditioner unit

I suppose that the water is coming from the unit where the blower motor is. Condensation is created by the evaporator coil while its running and is suppose to drain into a pan under it and through a pipe to the outside. This pipe could be stopped up. The easiest way to fix that is to blow air through the pipe from the outside. It probably comes out close to the outside unit. It could be that your inside filter is dirty causing reduced air flow and making the evaporator freeze too. Change the filter. That may help. There are other steps that you could take if these don't help. Contact me by email if you need to. Cant run over there because I'm in Missouri but may be able to help in a chat room.
