The heat-pump compressor is starting far more often than a healthy unit should.

Inrush, oil return and wear with little useful output.
Check the anti-short-cycle timer, thermostat deadband, refrigerant charge and sizing.
How Energy Agent prices a finding
Estimate the energy wasted on starts, and remember the wear is the bigger bill.
Enter positive numbers to see an estimate.
Each start costs roughly a couple of minutes of full-load energy before the unit is doing useful work. Extra starts above a sane rate, times that penalty, times the unit size and the affected hours. Energy Agent counts the starts from status trends.
Screening estimate. Energy Agent measures the real fault hours and load from your trends and prices them at your tariff.
Screening-level estimates; confirm with measurement and verification before capital commitment.
Electric resistance / auxiliary heat runs while it is warm enough for the compressor to carry the load.
The outdoor coil is defrosting far more than it should.
The unit says heating but the supply air is colder than return (or the opposite in cooling).
On a heat-pump (non-heat-recovery) VRF system, some indoor units call for heating while others call for cooling.
Send twelve months of interval data and a BAS trend export. Energy Agent returns a ranked list of what is wasting money, what each item is worth per year at your tariff, and what to do about it.
