I have central air...Its pushing 100 outside, And my A/C lines are full of ice.....Whats wrong???

Answer 1

Dude Steve, don't listen to the guy that said your compressor is locked. He doesn't know what he's talking about. Your lines wouldn't be frozen with a compressor malfunction. The compressor has to be working in order for your lines to freeze. In most cases what causes freezing lines are a dirty evaporator coil (the coil on the indoor unit), a dirty filter, and a low refrigerant charge. I wouldn't say it's a low refrigerant charge just yet. If it is, it usually takes a little while for your lines to start freezing. If your unit is still cooling the house, I would say that it's either the dirty coil, the dirty filter or if it did it since the day it was installed, it could actually be overcharged with refrigerant or the metering device is not operating correctly. If the charge or metering device has to be adjusted, you have to call a technician. To check the metering device, he will have to do a superheat reading. The superheat reading should be between 8-12 degrees Fahrenheit. This also has to be checked by a technician and it probably doesn't mean much to you, but at least that info will help you see if the technician is lying to you or not. I hope this information was helpful. if you have further questions, email my yahoo account.

Answer 2

Usually when the lines on the condensing unit(that big thing with a fan on the side of your house) are freezing up, you are low on charge. You need someone who knows what they are doing, and is certified to handle refrigerant to come check it out. You can't fix the problem yourself if it's low on refrigerant(freon).
Otherwise, if the outside condenser unit coils are clogged with grass clippings or weeds, turn off the air by turning up the thermostat to it's highest setting. This will stop it from running. Clean the debris from the coils. Let the lines thaw out, and give it another try. It might even cool down the house temporarly if the problem is not fixed permantly.
If you call a heating/AC contractor out to the house, it will save you money to have them come out durring the day. If you call them out at irregular times(like it's an emergency), they will charge you an obsene amount to just show up.
I know I've given you some of the same basic answers that others have, but I feel like you probably needed more complete answers. Good luck with the problem.

Answer 3

Compressor locked up, frozen or makes awful noise
Compressors are simply "pumps" with closely machined tolerances. They pump the refrigerant by means of pistons, rotary vanes or scroll technology. Like your car's engine they need a lubricant to reduce friction and reduce heat. R12 refrigerants use a mineral type oil, R134a refrigerants use either PAG or Esters. Each type of refrigerant requires that the oil mix with it. Either way you need oil (lubrication) especially since most compressors have aluminum cylinders and pistons and no rings. Two common problems will wear out or kill a compressor: excessive pressures or lack of oil. Lack of oil is the most common cause of failure. Lack of oil is caused by either:
(a) A low level of oil related to refrigerant loss over the years. As the refrigerant escapes from the system the oil is carried out with it. If your system was topped off or recharged without adding oil the result is similiar to running your car's engine without oil ..... worn cylinders and rings, but with aluminum as opposed to steel you get a melt down... quickly.
(b) Inadequate flow rate of refrigerant through the compressor, which can be related to several problems, such as running with a very low refrigerant level for a long period of time, failed expansion valve preventing refrigerant and oil to get back to the compressor. The a/c system relies on the refrigerant to "carry" the oil with it through the compressor. No refrigerant and no oil return, yet a compressor constantly running at a given RPM ..... means you are going to compressor melt down.
If the compressor is noisy (clanking or rapping or otherwise) don't run it. If you do run it you will contribute to the problem of system contamination. Have the compressor replaced and read below about de-contaminating the system.
If you are considering attempts to "loosen" up a locked compressor. Forget about it, the damage is already done (scratched pistons and bores and or wobble plate or vanes). The smartest thing to due is to dispose of the bad compressor and get a remanufactured or new unit.

Answer 4

Sounds plenty like your temperature regulator isn't turning directly to maintain freezing from occuring. As temps get cooler, your air conditioner would desire to turn on an off on it rather is very own to establish the strains do no longer freeze.

Answer 5

If your coils are dirty it could be causing this. They need to be cleaned at least once a year. You can clean them yourself with water (after the unit thaws). Or you could be low on freon.

Answer 6

You need to get that checked out. It sounds like there's a leak.

Answer 7

Your coolant is probably low. You need to contact a contractor who will refill your coolant.

Answer 8

Check your drain pipe it might be plugged, or you might need Freon

Answer 9

tthe unit is running harder than design raise the temperture
