Fix Steps:
1
Check all indoor unit filters are clean - clean or replace immediately
2
Verify outdoor unit coils are clean and unobstructed
3
Ensure all windows and doors in conditioned spaces remain closed
4
Check refrigerant pressure levels - low refrigerant increases power consumption
5
Verify compressor staging is working properly
6
Check if all indoor units are actually needed - turn off unused units
7
Inspect for refrigerant leaks using leak detector
8
Verify system is not oversized for space (causes inefficient cycling)
9
Check temperature setpoints - each degree lower increases consumption 6-8%
10
Review operating schedule - implement zone control and scheduling
