Why efficiency drops over time
Refrigerant charge drift, dirty coils and worn electrical components gradually reduce heat pump efficiency if left unchecked.
What a maintenance visit tests
Refrigerant pressures, water-side flow and temperature, and control safety functions are all part of a proper heat pump service.
Seasonal timing
Testing before peak heating demand helps catch efficiency issues before they become comfort complaints.
