Here’s a table summarizing the key differences between investing in a wall-mounted heat pump and an air conditioner:  Feature  Wall-Mounted Heat Pump  Air Conditioner  Functionality  Provides both cooling and heating year-round.  Only provides cooling, no heating capability.  Energy Efficiency  Highly efficient for both heating and cooling.  Efficient for cooling but requires separate heating system.  Cost  Higher initial cost, but savings over time with dual use.  Lower upfront cost, but higher overall cost if paired with a heater.    Environmental Impact  Lower greenhouse gas emissions; uses electricity efficiently.  Neutral; limited to cooling without heating benefits.  Space Efficiency  Consolidates heating and cooling...

Here’s a table comparing wall-mounted heat pumps and baseboard heaters for a 1,200 sq. ft. home:  Feature  Wall-Mounted Heat Pump  Baseboard Heaters  Energy Efficiency (COP)  2–4 (2–4 units of heat per 1 unit of electricity).  1 (1 unit of heat per 1 unit of electricity).  Heating Functionality  Provides efficient, even heating.  Provides direct heating with limited circulation.  Cooling Capability  Yes, also provides cooling in summer.  No, requires a separate cooling system.  Installation Cost  $3,500–$7,500  $1,000–$2,500    Annual Operating Cost  $400–$700 (electricity $0.13/kWh).  $1,200–$2,000 (electricity $0.13/kWh).  10-Year Operating Cost  ~$6,500  ~$16,000  Total 10-Year Cost  ~$12,000 (installation + operation).  ~$17,750 (installation +...
