My heat pump frosted up this winter and the service tech said that it was due to low refrigerant. He added 6 lbs of refrigerant.
Quick History: My heat pump was installed 7 or 8 months ago. The installer came back the day after installation to check for proper refrigerant level and topped it off.
So my question is why did he have to add so much? Do I have a leak?
Is there a way to check or monitor for Low Refrigerant using my carrier infinity control (SYSTXCCUIZ01) so I can alert the service tech and make sure my heat pump is running optimally? Or is there some other way for me to check?
Under heat pump status on the infinity control, there is a read-out called suct. press: in PSIG. Is this something useful?
