Heating Repair & Installation in South Florida
Yes, Florida gets cold — not often, but when a cold front drops Boca Raton into the 40s or Fort Lauderdale into the high 30s, a broken heating system is a real problem. AtlantFlow AC & HEAT repairs and installs every kind of heating you’ll find in South Florida homes: heat pumps, electric strip heat, gas furnaces, and mini-split heat.

Heat Pumps: The South Florida Standard
Over 80% of South Florida homes heat with a heat pump — the same outdoor unit that cools your house in July reverses in January to pull heat from outside air. At outdoor temperatures above 35°F, a heat pump is dramatically more efficient than electric strip heat or a gas furnace.
We install, repair, and maintain heat pumps from Carrier, Trane, Lennox, Goodman, Rheem, Bryant, and Daikin. Common heat pump problems we resolve:
- Blowing cold air in heat mode (reversing valve, defrost control, low charge)
- Auxiliary heat running constantly (thermostat or outdoor sensor fault)
- Ice buildup on outdoor unit (failed defrost cycle)
- System won’t switch to heat mode
- Loud compressor on startup
Electric Furnaces & Strip Heat
Most Florida air handlers have 5kW, 10kW, or 15kW electric resistance heat coils used as auxiliary or emergency heat. They’re simple and reliable but expensive to run — a bad sequencer or stuck contactor can silently cost $100s on your FPL bill. Our techs test every element, sequencer, and high-limit switch during service.
Gas Furnaces (Less Common, Still Here)
Some older homes and a small number of new luxury builds use natural gas furnaces. We service induced-draft 80% AFUE and condensing 90%+ AFUE furnaces — ignition, flame sensors, gas valves, heat exchangers, and venting. If you smell gas, leave the house and call your gas utility, then call us.
Ductless Mini-Split Heat
Popular in guest houses, additions, garage conversions, and Florida rooms. Mitsubishi, Fujitsu, Daikin, and LG mini-splits heat efficiently down into the 20s. We install new systems and repair existing ones.
Common Heating Symptoms We Diagnose
- No heat at all — thermostat, breaker, control board, or fuse
- Cool air from vents — reversing valve, low refrigerant, or thermostat set wrong
- Burning smell — dust burning off strip heat (first use of the season is normal; persistent smell is not)
- Breaker trips when heat calls — overloaded strip heat, shorted element, or weak breaker
- High bills in January — aux heat locked on, or failing heat pump
Heating Installation & Replacement
If your heat pump is 12+ years old or your furnace is 15+ years old, it’s worth getting a replacement quote. Modern inverter heat pumps heat down into the teens without strip heat, and cost 30–40% less to run than a 13-SEER system.
Every installation includes:
- Free in-home estimate
- Manual J load calculation
- Permit & inspection
- 12-year labor warranty on qualifying systems
- 0% APR financing up to $25,000
Thermostat Installation
Most Florida heating problems are actually thermostat problems. We install and configure smart thermostats — Nest, ecobee, Honeywell T-series, and Sensi — properly wired for heat pumps with O/B reversing-valve logic (a common miswire we correct on new customer calls).
Frequently Asked Questions
My heat pump is blowing cool air in heat mode. What’s wrong?
Often a stuck reversing valve, low refrigerant, or a failed defrost control. Sometimes just a thermostat set to “cool” or “emergency heat” accidentally. We diagnose same-day.
Why is my FPL bill so high in January?
Usually because the heat pump isn’t engaging and the system is running on electric strip heat (3–5x more expensive). A quick diagnostic identifies the issue.
Do you service gas furnaces?
Yes, though they are rare in South Florida. We service 80% and 90%+ AFUE units from all major brands.
How long does a heat pump last in Florida?
12–15 years is typical. Coastal homes get less; well-maintained inland systems can hit 18 years.
Can a heat pump really keep up in a Florida cold snap?
Yes. Modern inverter heat pumps heat effectively down to 17°F — well below anything South Florida sees. Older units rely on strip heat below about 35°F.

Heating Service Costs in South Florida
South Florida homes typically use heat 15-25 nights per winter — so most systems here are heat pumps with electric strip heat backup, not furnaces. That simplicity has a hidden cost: when strip heaters fail unnoticed for 8 months, the first cold snap in January reveals the problem at 3 AM. Our tune-up and repair pricing:
| Service | Typical Price |
|---|---|
| Heat pump tune-up (defrost control, reversing valve, charge) | $189 |
| Electric strip heat element replacement | $320–$680 |
| Heat pump reversing valve | $580–$1,100 |
| Defrost control board | $290–$520 |
| Heat pump auxiliary sensor | $180–$340 |
| Thermostat swap (heat/cool smart) | $220–$450 |
| Natural gas furnace tune-up (rare in FL) | $189 |
| New heat pump install (replaces AC + heat) | +$400–$1,400 over AC-only |
Fall Heating Check — 11 Point Inspection
- Cycle system into heat mode & verify reversing valve operation
- Test all strip heat elements individually (amp draw on each)
- Inspect sequencer for proper staging
- Check outdoor defrost cycle trigger
- Clean outdoor coil and inspect fan for ice damage
- Verify thermostat heat/cool calibration
- Test emergency heat mode
- Inspect indoor blower wheel and filter
- Check ductwork for leaks with smoke test (larger homes)
- Verify CO detectors are working (if gas system)
- Written report with photos + next-year forecast
Heat Pump vs Furnace — What’s Right for Your Home
For 95% of South Florida homes, a modern heat pump is the right answer — same unit cools in summer and heats in winter, at roughly 3× the efficiency of electric strip heat. The exceptions: very large homes with existing natural gas, or owners who want redundancy during hurricane-related power outages.
