Different system roles
Air conditioners provide cooling. Heat pumps can provide both heating and cooling, depending on system design and climate.
Comparable efficiency ratings
Efficiency metrics vary by equipment type. Check which metric each contractor provides rather than treating unlike ratings as interchangeable.
Included components
A heat pump proposal may involve backup heat, controls, and integration with existing equipment. Confirm exactly what is included.
Installation and incentives
Ask about electrical scope, thermostat requirements, commissioning, and any claimed rebates or incentives. Verify eligibility independently.
Decision context
Existing equipment, local climate, home load, utility pricing and contractor design matter. A written estimate alone cannot determine suitability.
