A common question is: Is it normal for heat pump noise when air source heat pump is defrosted?
If your air source heat pump makes a loud noise in cold weather, it may just be entering or exiting the defrost cycle - this is normal for winter conditions.
In cold climates, the defrost cycle of an air source heat pump reverses the system to melt the frost. This can cause:
1. Valve shifting sound
2. Fan pause or rotation
3. Compressor restart
These changes can cause the air source heat pump to make noise temporarily, not malfunction.
