A heat pump reverses its cycle and runs in both, which roughly doubles the annual hours on the compressor and adds the mechanical stress of reversing valve operation and defrost cycles. Compressor durability stops being a specification and starts being the whole decision — which is the argument for Climatuff® here specifically.\u003c\/p\u003e\n\n\u003ch3\u003eHow it heats\u003c\/h3\u003e\n\u003cp\u003eInstead of burning fuel, the system moves heat from outdoor air into the house. There is usable heat in 40°F air, and relocating it costs a fraction of generating it — which is how heat pumps reach efficiencies a resistance heater cannot approach.\u003c\/p\u003e\n\u003cp\u003eCapacity does fall as it gets colder, and below a certain outdoor temperature the system leans on electric heat strips. Across Florida, the Gulf Coast and most of the Southeast that threshold is rarely reached. In colder regions a heat pump is normally paired with a furnace in a dual-fuel configuration.\u003c\/p\u003e\n\n\u003ch3\u003eSizing — 1.5 to 5 ton\u003c\/h3\u003e\n\u003cp\u003eSeven capacities. Heat pumps are sized on the cooling load and then checked against the heating load, so a Manual J calculation matters more here than on a cooling-only system.
