Carrier Heat Pumps in Florida — Are They Worth It?

A heat pump is an air conditioner that can reverse direction. In summer it pumps heat from inside to outside (cooling). In winter it pumps heat from outside to inside (heating). On the Treasure Coast, that's a much cheaper way to heat than electric strips.

How well a heat pump heats in Florida

Above 40°F outdoor, a heat pump produces 3–4 units of heat for every 1 unit of electricity (COP of 3–4). An electric strip produces exactly 1 unit of heat per 1 unit of electricity. So when it's 50°F outside on a January morning, a heat pump heats your house at 1/3 the cost of strips.

When the heat pump struggles

Below 40°F outdoor, capacity drops fast. Below 32°F, most residential heat pumps need help from auxiliary electric strips. On the Treasure Coast we hit those temps a handful of mornings a year. The system auto-switches — you don't do anything, but your electric bill spikes for those days.

Heat pump vs. straight AC pricing

A 3-ton Carrier heat pump runs about $500–$1,200 more installed than the equivalent straight AC. Most homeowners save that back in 2–3 winters of avoided strip heat. Almost every new install we do on the Treasure Coast is a heat pump.
