Keep the assessment safeDo not open equipment, touch wiring or refrigerant lines, change controls, or attempt a swap to investigate. Use records you already have and ask a professional to assess the proposed system. This is planning guidance, not a diagnosis or repair procedure.
An air-source heat pump provides heating as well as cooling, changing the choice from cooling-only replacement to whether you also want heating. That function difference does not show that your outdoor unit can be swapped alone or that existing equipment is compatible. DOE describes the combined function; ENERGY STAR does too.
More context for this decision
Details that can change the next step
Use the source examples within their stated limits.
How does a heat-pump proposal change the intended function compared with cooling-only central replacement?
Cooling only or heating and cooling?
Choose the intended function: central cooling only, or cooling plus some or all heating. The sources do not decide what suits your home or whether its existing heat source should stay, change, or serve another role.
ENERGY STAR gives one conditional example: with a relatively new gas or oil furnace and older central AC, a homeowner may consider a heat pump alongside the furnace. This does not establish compatibility or tell you to keep or remove equipment.
Compare proposals by scope
Keep the intended function and scope clear
Move from information to action
Before comparing proposals
Compare proposals by scope
Ask for comparable written proposals that state:
Cooling only or heating and cooling; equipment to remain or change; and the intended role of the existing heat source.
The sizing basis for this home; how airflow will be checked against manufacturer specifications; and how ducts will be evaluated.
How will the proposed system's refrigerant charge be checked?
These are comparison prompts, not universal requirements. ENERGY STAR's installation guidance supports asking about home-based sizing, manufacturer airflow specifications, refrigerant-charge checks, and duct evaluation. The sources do not resolve this home's equipment match, controls, electrical scope, or design.
