Upon coming home from errands noticed outside A/C unit pipes covered in ice and found compressor totally covered in ice. Inside temps is 83*F ..Outside temp 90*F but feels like 98*F.....the expected high to be 95*F expected.... Have already called a HVAC company that have used in the past who treated us alright. No arrival time set. Will get here asap ..Home ac unit approx 19 years... Keeping fingers crossed...... drill sgt. ........... drill sgt. | ||

Sounds like the system is low on refrigerant. Hopefully it is that and not a leak. The core in the furnace tends to get pinhole leaks after time and may need to be replaced. Not cheap. Good luck.

Just went through the same situation. Turn off the AC but run the blower 24/7. That will allow the system to thaw and thereafter you can run the AC but be sure to monitor it so that when it freezes again you turn off the AC and just run the blower. We also moved our dehumidifier upstairs from the basement, ran the blower 24/7, and used portable fans while waiting for the service tech. For us the quickest a service tech could get to us was 7 days. The fix for us was simply 2lbs of R-22 and we were back in business. Good luck! | |||

I just went through the same thing. Leak in the evaporator coil, it was replaced, topped off with refrigerant (410A -- h2oys, is your system still using R22?), a valve replaced, all done two days ago, and we're good now. Your problem is low coolant stuff, freon or replacement. Need to get the leak fixed, and the system topped up, and you'll be good. ADDED: Just noticed 19 years. Might be system replacement time. הרחפת שלי מלאה בצלופחים | |||

Several things could cause it . Stopped up filter . Fan not running . Low Freon charge . | |||

Please search this forum for numerous threads on HVAC systems. My simplistic summary of the threads is: 1. Choose a great dealer 2. Do a real load calculation 3. Ensure your ducts and duct design are correct 4. Choose a reputable brand with a scroll compressor. 5. Enjoy. ------- Trying to simplify my life... | |||

If it is low on refrigerant it IS a leak. 19 years is a good run. It is possible they can replace the refrigerant but the problem will likely recur. Probably time for a new unit. Missed your update. I agree start pricing systems. | |||

I don't know I've ever seen a compressor have ice on it. The low pressure/suction line often can get ice on it or the evaporator coils can get ice on them. Are you talking about the thing in the bottom center of your outdoor unit? Jesse Sic Semper Tyrannis | |||

^^^^^^^^^^^ YUP.. That big black tall cylinder in the bottom of the outside on the ground unit..... drill sgt. | |||

I’m curious why the compressor would be covered in ice. Does low coolant cause it to boil on the pressure side and cause ice to work back to the compressor? Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well. -Epictetus | |||

The two sentences kind of contradict each other... leaks cause a system to be low. Otherwise, are you suggesting a magician stopped by and made it disappear? | |||

As refrigerant pressures drop, so do the temps. Shit goes south when refrigerant temps go under 32 degrees F. | |||

A plugged drain will cause this also. | |||

^^^ No, it will NOT. If you *think* so, please explain how a plugged drain freezes water. | |||

When you get quotes, please just compare total numbers. Some HVAC companies try to charge absurd markups on equipment, without indicating it on their quotes. They don’t really have an inventory carrying cost. TMK they almost always just order a unit in from a distributor, as needed. | |||

Vtail: We are very lucky as our system is original to our 40 year old home. Yes, it’s a 40 year old Carrier unit. Hence we still us r-22. Our service tech told me to run it til it drops as new units aren’t built to last like the old ones. Luckily over our 24 years in our home we’ve only replaced the fan and added 6lb of Freon. DrillSgt: glad to hear it was a simple fix! PSA: when our service tech added the 2lb of r22, which by the way cost $100/lb, he told me 410 is being phased out for a new refrigerant. Hence stock up now as it will go way up in price as supplies dry up. | |||

Make sure you dont have a plugged filter. Or one with too high a MERV rating. Lack of proper airflow can cause frozen coils like this. I used to have some unusual kind of metal filter that was washable and never needed replacement. It worked fine in the winter, but froze up the coils the first really hot day. Switched to regular filters and no more problems. | |||

Sorry I been away, YES ^^^ it will. Backed up water in the line will freeze all the way back to the evaporator coil. Happened to me.  | |||
