Because it does both jobs. A straight-cool air conditioner needs separate heating equipment, whereas a heat pump reverses its refrigerant cycle to heat — one system, one install, one thing to maintain. In East Central Florida, where heating demand is real but limited to cold fronts, that is the efficient arrangement, and it also improves humidity control.

One of two things, both expensive. Undersized, it struggles to maintain comfort and calls on auxiliary electric strip heat to cover the gap. Oversized, it short-cycles and never runs long enough to control humidity properly. Strip heat is the costly way to warm a building, so a sizing error tends to arrive as a winter energy bill rather than as an obvious fault.

Yes, and it is one of the more common installations we do. The conversion involves new outdoor and indoor equipment, refrigerant line work, electrical verification, auxiliary heat configuration, and a thermostat that understands heat pump operation — a standard thermostat cannot control the reversing valve. It is a full installation rather than a swap.

Yes, as backup, but the goal is for it to stay mostly idle. Auxiliary strips cover the coldest mornings when the heat pump alone cannot keep pace. Correctly sized equipment with properly staged aux heat means the strips engage rarely; badly configured, they engage constantly and you pay for resistance heat you did not need.

It should. Salt air accelerates corrosion on condenser coils and cabinets, so properties near the Atlantic in Ormond Beach, Daytona Beach Shores, Ponce Inlet, and Flagler Beach benefit from coastal-resistant equipment. It is a specification decision at install time that affects how long the system lasts.

Only if the equipment was the cause. New equipment behind restricted or leaking ductwork delivers the same uneven temperatures it always did, which is why we verify airflow and duct performance as part of installation rather than after complaints. Where distribution is the real problem, ductwork correction or zoning is the fix.
