is heat pump worth it
A heat pump can be weighed when a furnace or central air conditioner needs replacing. ENERGY STAR: “In most zones, an ASHP can be installed as a drop-in replacement when either a central air conditioner or a furnace needs replacement.” Its undated page, read in 2026, adds: “heat pumps serve double duty by also providing cooling in the summer months”.

Match the heat pump to the equipment you have
ENERGY STAR's product page puts the ducted case this way: “For some, it may be helpful to think of a ducted ASHP as a central air conditioner that also works in reverse to provide whole-house space heating in winter.” For a home without ducts, the same page adds that “you can still install a heat pump to heat and cool a portion of your house”.

What is a heat pump?
ENERGY STAR's air-source heat pump page compares a ducted unit with central air conditioning run in reverse: “For some, it may be helpful to think of a ducted ASHP as a central air conditioner that also works in reverse to provide whole-house space heating in winter.” (Undated ENERGY STAR product page, read 2026-11-09, US.)

What are the disadvantages of a heat pump?
The ENERGY STAR page carries no list of drawbacks; it names conditions to plan for. On sizing: “A system that is either too large or too small for its intended space will struggle to meet your home comfort needs.” On cold winters: “If you live in a climate where winter temperatures regularly dip below freezing, talk to your contractor to choose an ENERGY STAR unit suited to your particular home.” (Undated ENERGY STAR product page, read 2026-11-09, US.)

Plan for sizing and the coldest weeks
For colder regions, ENERGY STAR's page records that “Climate ASHP technology has improved significantly over the past several years, and many ASHP systems are capable of delivering heating capacity and efficiency at low outdoor temperatures.” It also lists this step: “Your HVAC contractor can help determine what size system is right for your home.” (Undated ENERGY STAR product page, read 2026-11-09, US.)

Before requesting work, write down what the home has now: the furnace or boiler, any central air conditioner, whether ducts reach the rooms you want heated and cooled, and how cold the coldest weeks get. Ask each contractor to state the proposed system size in the written scope and how the home will be heated on the coldest days. Compare those written answers side by side, not the equipment name alone.
