The coals on the airconditioner keep freezing up with ice what should I do?
Question:
Answers:
The coils on your AC are freezing up with ice because the unit is low on Freon. This gas will slowly leak out of the system over time and as it does, the ability to cool is impacted. The result is that the gas must get colder than normal to keep the house cold, and when it does, the gas in the coils causes water in the air to freeze on the outside.
The AC will continue to work for a while, but eventually, the compressor will fail because the freon level gets too low. When this happens, the repair will be very expensive. Call your A/C repairman and have them recharge the system.
Note.unless you get a reputable repairman, the AC company is going to tell you that you need to buy a new system. I would insist that they recharge the system with freon first, and see how long it takes for the icing to begin again. Too many AC repair companies are disreputable and will try to sell you a new system when you don't need one.
The worst that can happen is that you will spend $200 on a freon charge, and later on the AC unit still needs to be repaired. In the best case however, you may delay a very expensive replacement for another couple of years.
But no matter what you decide...your existing system is low on freon and needs attention.
You are in need of freon. Get the unit serviced, or replace it (depending on which is cheaper)
I'm assuming you're talking about coils on a window air-conditioning unit. There are three things that come to mind, and we'll start with the simplest first.
1. Are the filters or screens dirty? If so, remove from the unit and rinse them thoroughly. Re-install on the unit. Also, be sure to check the condition of the coils themselves as bent fins or excessive dirt can cause this situation.
2. Are you closing the door to the room while the unit is left to run? This can cause the room temperature to drop down low enough that a "no-load" condition develops, and the coils will freeze over. Try to keep the door open if possible. If not, adjust the thermostat on the unit so that it cycles automatically at, say, 72 - 75 degrees.
3. It could be that the unit is low on freon, a condition that would indicate a leak. I'm not sure how old the unit is, but in all likelihood, if this is the case, you will need to have a qualified technician look at it.
If this is, in fact, a central air-conditioning system, the filters, coil condition, and leak still apply.
Hope this helps.
Usually this happens if you have a freon leak making your unit low on gas. You'll have to call a technician and he'll do a leak check and repair the leak and recharge the unit with freon. Hope this helps, but you need to call a professional
