So you don’t have any air conditioning and you walk outside and you see ice all over your air conditioner. You’ve got a freezing up problem. Stay tuned and we’ll talk about that for a few minutes to tell you what to do. Home Care & Maintenance: Air Conditioner Freeze Up with Dan Jape So many times when you don’t have air conditioning, you’ll go outside and you’ll see ice on your outdoor unit, and you think you’ve found the problem.
You’ll turn it off, some of the ice will melt and you’ll try to turn it back on. You think you’ve fixed the problem.
Well, the real problem starts inside on your indoor coil. This coil will be a solid block of ice and this area that you see here will be completely encrusted with ice, oftentimes an iceberg, sometimes two or three feet high.
And until that ice is melted you can’t get any air through the cooling coil. So the big mistake when you have a frozen unit is you turn it off and you turn it back on in an hour and it just starts icing up again. What you have to do when an air conditioner ices up is it has to thaw.
Generally overnight, four, five, six or seven hours because the volume of ice is such that it will just take a long time to thaw. You have to be very careful to during this thawing process because that ice will melt into water come down and cascade down on the furnace, many times burning out components in the furnace.
Now and air conditioner should never ice. If you ever see any ice on the outdoor unit or on the big line there’s a malfunction. There’s a problem. Many times people will let it thaw, they’ll turn it back on they’ll get cooling for a short time and then they think the problem’s fixed itself.
They’ll actually call our company, set up a service appointment, the ice will thaw, they’ll cancel that appointment and then the next day they’re back on the line frantically. An air conditioner should never have ice on the line, the big line, or any other lines or any of the tubes. If you ever see ice you have to call for help. There’s a couple reasons why an air conditioner can ice.
One of the most common ones is a dirty furnace filter. If you don’t have enough air across this coil it will start to ice. But the most common problem we see is a lack of freon and when the freon drops in the unit the surface temperature drops so cool that the water the spleen removed from the air freezes this surface.
When this surface gets blocked with ice then that ice starts building up, building up the which works very much like the ice maker in a refrigerator.
So icing is always a problem that if you don’t have a dirty filter you need to call your heating and air contractor tell them what the problem is and turn the unit off.
One of the biggest issues that we have with frozen units is people call for help and they think that if they leave the air conditioner running they’re gonna have cooling while they’re waiting for us to get there. That’s not true. If you can’t get air across the cooling coil you’re not going to have any cooling.
As a matter of fact you can burn up your air conditioner to leave it running with ice on it. So you need to call your contractor and regardless of how uncomfortable you are turn it off. And you need to wait at least four or five hours to have them come out. Because if they get there and there’s any ice left on this coil there’s not a thing they can do technician’s usually gonna charge you a service call turn around and leave and tell you he’ll be back the next day. Many, many times people say they turned it off and they don’t and they’re very unhappy because we can tell.
And remember until that ice is all gone you’ve got a problem. If you like our articles, please leave a comment below. And for a new home care article every week subscribe to our website website.
