Common Heat Pump & Heating Issues in Central Florida
Because Florida systems run in cooling mode 95% of the year, heating components sit idle for months. When cold weather hits, dormant parts and safety switches get tested for the first time.
The "Burning Smell" on First Turn-On (And Why Pre-Testing Matters)
When electric heat strips sit unused for 8 to 10 months, household dust, hair, and pet dander settle directly onto the heating coils. Turning on heat for the first cold night instantly incinerates that dust, producing a strong burning odor that often sets off home smoke detectors.
The Proactive Fix: Run your heat for 10–15 minutes on a mild autumn afternoon with windows cracked open. This cleanly burns off debris ahead of time so your family isn't dealing with smoke alarms in the middle of a freezing night. If the burning smell persists longer than 20 minutes, shut the system off immediately and call for an inspection.
Heat Pump Blowing Cool / Luke-Warm Air
The Cause: In Florida, this almost always points to a stuck reversing valve (preventing the refrigerant from reversing into heating cycle), low refrigerant charge, or an open limit switch on the heat strip kit.
Outdoor Condenser Encased in Ice
The Cause: Frost is normal on outdoor heat pump coils during cold weather, but the unit should melt it via an automatic defrost cycle. If the defrost board or sensor fails, ice encases the coils and starves the system of heat.
Auxiliary / Emergency Heat Stuck On
The Cause: Electric heat strips pull massive amounts of electricity (up to 10kW–20kW). If an electrical heat sequencer welds shut or the heat pump fails, your system runs on expensive auxiliary heat 24/7.
Heater Trips Breaker or Won't Ignite
The Cause: Auxiliary heat pulls the highest electrical load in your entire home. Corroded lugs, sagging nichrome wire coils touching metal casing, or bad thermal fuses will instantly trip main breakers.
Heat Pump vs. Auxiliary Heat Strips: How Your System Heats
Unlike northern homes with gas furnaces, Central Florida homes rely on a dual-stage electric climate system. Understanding the difference between primary heat pump operation and backup heat strips saves you hundreds in energy bills.
The Thermodynamic Heat Pump Cycle
High Efficiency • Low Electricity Consumption
A heat pump doesn't "create" heat with fire or red-hot metal coils—it reverses the air conditioning cycle. A specialized component called a 4-way reversing valve flips the direction of the refrigerant. The outside condenser extracts latent thermal heat from the outdoor Florida air and pumps it inside through your ductwork.
-
✓
Extreme Efficiency (COP 3.0+): Delivers 3x more heat energy than the electricity it consumes.
-
✓
Gentle Air Temperature: Delivers supply air around 88°F–95°F, keeping your home warm without scorching dryness.
-
✓
Reversing Valve Solenoid: Controlled by a 24-volt electrical coil that switches between heating and cooling seasons.
Electric Auxiliary Heat Strips
Instant High Heat • Heavy Power Draw
Inside your indoor air handler sits a bank of coiled nichrome resistance wire (similar to giant toaster elements), typically rated at 5kW, 8kW, or 10kW. When outdoor temperatures plunge into the 30s or your heat pump enters its defrost cycle, electrical sequencers turn on these elements to provide rapid emergency heat.
-
✓
High Electrical Amperage: Draws up to 20 to 45 amps—often causing winter power bills to surge if stuck on.
-
✓
Thermal High-Limit Safeties: Built-in thermal cutoffs prevent the element bank from overheating the air handler.
-
✓
Time-Delay Sequencers: Stagger the elements so multiple 5kW banks don't spike your main electrical panel at once.
Frequently Asked Questions About Heating & Heat Pumps
Straight answers to common questions about Florida heating systems, heat pump defrost cycles, and electric strip safety.
This is the most common call we receive during Florida's first cold snap. Because heat strips sit dormant through spring, summer, and fall, household dust and pet dander settle directly on the metal heating coils. When the heat kicks on, that dust immediately incinerates, causing a sharp burning odor that can trigger smoke alarms. It usually clears after 15 to 20 minutes. If the smell persists longer or is accompanied by electrical arcing sounds, shut off the breaker and call us immediately.
It is rarely smoke—it is almost always steam from the automatic defrost cycle. When outdoor temperatures drop below 40°F, moisture in the air freezes on the condenser coils. The heat pump's control board periodically reverses into cooling mode for 2 to 10 minutes to melt this frost, turning off the outdoor fan so heat builds rapidly. As the frost melts off the hot coil, warm steam rises from the top of the unit.
You should only switch to Emergency Heat if your outdoor heat pump has completely failed (e.g., locked compressor motor, broken fan, or encased in thick ice) while you wait for a technician. Emergency Heat bypasses the outdoor compressor entirely and forces your high-voltage electric heat strips to run 100% of the time, which can rapidly increase your TECO or Duke Energy electric bill.
Unlike gas furnaces that blast 120°F–130°F air, heat pumps deliver steady, energy-efficient heat around 88°F to 95°F. Because your skin is around 98.6°F, air blowing at 90°F can feel slightly cool to the touch even while it effectively heats the room to 72°F. However, if your supply vents are blowing room-temperature or cold air below 80°F, your reversing valve or heat strip sequencers require diagnostic testing.
The 4-way reversing valve is the mechanical brain of a heat pump. Controlled by a 24-volt solenoid coil, it physically redirects refrigerant flow to alternate between air conditioning and heating. Because it remains in cooling mode nearly all year in Florida, internal slide pistons can stick or solenoid coils can burn out, leaving the system locked in cooling mode even when your thermostat is calling for heat.
Yes. We never charge a diagnostic fee when repairs are performed. A technician inspects the reversing valve, checks sequencer amp draws, tests thermal limit switches, and provides an upfront, flat-rate quote before any repair work begins.
