So we moved into this new home the start of November and the system would make a whining noise that could be heard everywhere in the house for about an hour before the defrost cycle would start. They decided this was because instead of 16 pounds of refrigerant they had 14 pounds in the system. They added more refrigerant and since that I now get this noise for about an hour before the defrost cycle kicks in:

Can anyone with a carrier infinity greenspeed tell me if they get this same kind of noise? I asked the installer, but he told me 'that's the inverter tech'. I can't believe that this is a normal noise, even my neighbour has told me he finds it annoying, you can only imagine how l feel about listening to it inside.
He also set the lockout for electric set at 18F, does that seem high? It was -15C yesterday and it took $11 in electric and $6 of heat pump to heat my house for the day. (the house is a total of about 2400sq feet).
Any help or input would be greatly appreciated.
Thank You,
Paul
