I hope someone can help with this. Two weeks ago I purchased a Goodman 2.5 ton split system heat pump. A couple of days ago the temperature dropped to about 20 degrees and the unit was running constantly and never getting up to the desired temperature on the thermostat. I checked outside and the outside unit was froze solid like a block of ice, inside and out. Obviously the defrost cycle was not working properly. I called the serviceman and he told me to put it on emergency heat until he could check it out. The next day the sun melted all the ice on the unit and I switched it back on. It worked perfectly, it defrosted correctly, etc. The serviceman checked the freon levels and said they were fine. He said it could be the control board, but he wasn't sure. It works fine now, wouldn't it not work at all if the board was bad? He is stumped and so am I. I am worried that this will happen again when the temperature drops. What does anyone suggest? Please I need help here.

Another time that heatpumps will freeze up is when there is high humidity outside at near freezing temps. Seperate comment: on heat pumps I would recommend that you have your service man install a heater on the commpessor oiltank. The oil gets thick when it is cold and evertime the compressor starts it is slugging that cold oil. Hard on the compressor.

I hate heatpumps! Noisy, cold drafts, run all the time.

Is there any chance the unit is sitting where there's a drip from the roof or a gutter? I had problems with one that kept getting water init, then freezing on cold nights.
Not sure how that caused it to fail, but the problem seems to be solved by fixing the drip.
