JustEm Posted February 8, 2014 Share Posted February 8, 2014 Ugh! If its not one thing its something else. Out exterior unit is frozen over. I noticed this not too long ago. This is a new system (we replaced it in August.) Called our HVAC guy and left message. Anyone know what I should do while I wait for him to call back? I assume turning the heat off is a good idea since it can't really work if its frozen over. Anyone have experience with this? Quote Link to comment Share on other sites More sharing options...
regentrude Posted February 8, 2014 Share Posted February 8, 2014 I assume you are currently heating and not cooling? (I don't know in which climate you live). If heating: Do you have the heat pump as the sole source of heating, or do you have a backup furnace as well? If you have a furnace: switch over to "emergency heat" and run the furnace instead of the heat pump. The pump will thaw out when it gets warmer, or you can thaw it. Running it when it is frozen up can damage the blades, so you should switch it off. Quote Link to comment Share on other sites More sharing options...
JustEm Posted February 8, 2014 Author Share Posted February 8, 2014 thank you! I can't believe I didn't even think of that. Silly me. Its not our sole source so we're good for now. Quote Link to comment Share on other sites More sharing options...
Pawz4me Posted February 8, 2014 Share Posted February 8, 2014 Typically a frozen over heat pump means a coolant leak. The coolant used to be freon, but they've switched to something more environmentally friendly that I can't remember the name of. The trick is finding the source of the leak. Sometimes it's easy, and sometimes it takes multiple trips by a technician to figure it out. Yours should still be under warranty, so there shouldn't be any cost to you. But I hope the technician can find the leak quickly. Quote Link to comment Share on other sites More sharing options...
Tammyla Posted February 8, 2014 Share Posted February 8, 2014 My parents had theirs freeze up. The pipe needed to be moved; I think it was installed wrong, it kept freezing in the summer with the AC on. I hope you get it working soon.

regentrude Posted February 8, 2014 Share Posted February 8, 2014 Typically a frozen over heat pump means a coolant leak. yes- if it is freezing up in the summer when you are running the AC. In winter, freezing rain or even high humidity with subfreezing temps will freeze up the outdoor unit even if there is no leak. Happened to us three times this winter already ;-) After all, the thing is outside. Quote Link to comment Share on other sites More sharing options...
Pawz4me Posted February 8, 2014 Share Posted February 8, 2014 We've had a heat pump freeze up in winter due to a coolant lmeak Quote Link to comment Share on other sites More sharing options...
