The problem with heat in Florida
Most Panhandle homes run heat pumps, which means the same equipment cools you in August and heats you in January. The heating side gets used for a few weeks a year, which creates a specific and annoying pattern.
A fault on the heat side does not announce itself in July. A failed reversing valve, a seized auxiliary heat element, a defrost control problem or a bad sequencer can sit undetected through an entire cooling season. Then the first genuine cold snap arrives, every house on the coast calls for heat on the same evening, and that is when you discover it.
Inland this matters more. Freeport and the areas north of the bay sit far enough from the Gulf’s moderating effect that cold snaps land harder and the heat side works more.
What usually fails
Reversing valves switch a heat pump between cooling and heating. When one sticks, you get cold air on a call for heat, which is alarming and looks like a much bigger problem than it is.
Auxiliary heat strips are the electric resistance elements that supplement the heat pump when it is genuinely cold. They fail quietly. The house heats slowly, the system runs constantly, and the bill climbs.
Defrost controls manage frost on the outdoor coil in cold, damp weather. A faulty control either never defrosts, so the coil ices over and capacity collapses, or defrosts constantly and wastes energy.
Capacitors and contactors fail on the heat side exactly as they do on the cool side.
Diagnosis first
The same discipline applies as on a cooling call: measurements before parts. Electrical draw, capacitor condition, refrigerant pressures, defrost operation, auxiliary heat staging and the thermostat signal end to end.
Heat pump heating complaints are particularly prone to misdiagnosis, because “blowing cold air” can mean a reversing valve, a refrigerant problem, a defrost cycle behaving normally, or simply a heat pump delivering air at a temperature that feels cool against skin while still heating the house. Those need separating properly rather than guessing.

Emergency heat
Losing heat during a cold snap is an emergency, and we treat it as one. Emergency response runs 24/7 with no after-hours surcharge for Comfort Club members on nights, weekends or holidays.
If your system is blowing cold on a call for heat, switching to emergency heat at the thermostat will usually keep the house warm until we arrive. It is expensive to run for long, but it is far better than a cold house.

Frequently asked questions
My heat pump is blowing cool air. Is it broken?
Not necessarily. Heat pumps deliver air cooler than a furnace would, and a defrost cycle briefly blows cool by design. If the house is not reaching temperature, though, it needs looking at.
Why does my system run constantly when it is cold?
Often the auxiliary heat has failed, leaving the heat pump to do everything alone. It will run continuously and still struggle.
Should I use emergency heat?
As a stopgap when the heat pump is not heating, yes. It is costly to run continuously, so it is a bridge rather than a solution.
Do I need heating service if I live on the beach?
Less urgently than inland, but a heat pump’s heating side is worth checking annually, because a fault found in autumn is cheaper than one found in January.
