Inverter Technology is an advanced feature in modern heat pumps, air conditioners, and HVAC systems. It refers to the use of a variable-speed compressor, which allows the system to adjust its output continuously to meet the heating or cooling demands of a space. This is in contrast to traditional “on/off” systems, which have fixed-speed compressors that operate at maximum capacity or turn off entirely.  Key Differences Between Inverter and On/Off Systems  Feature  Inverter System  On/Off System  Operation  Continuously adjusts compressor speed to match demand.  Operates at full capacity or shuts off completely.  Energy Efficiency  More efficient due to variable-speed operation. ...

Basic Definitions  - SEER: Measures cooling efficiency over an entire season.  - HSPF: Measures heating efficiency over an entire season.  - COP: Measures instantaneous efficiency in heating or cooling.  ---  What are the key differences between the three?  - SEER:    - Focus: Cooling only.    - Units: Seasonal ratio of cooling (BTU) to energy used (watt-hours).    - Applies to: Air conditioners and heat pumps in cooling mode.  - HSPF:    - Focus: Heating only.    - Units: Seasonal ratio of heating (BTU) to energy used (watt-hours).    - Applies to: Heat pumps in heating mode.  - COP:   ...
