Common Heating Problems We Fix The Issues We See Every Winter in Northwest Florida
Reversing Valve Stuck (Heat Pumps)
What causes it: Mechanical failure, low refrigerant, electrical problems, or age. The reversing valve switches your heat pump between cooling and heating modes.
What you'll notice: Heat pump runs but blows cold air. Or it won't switch to heating mode at all.
How we fix it: Diagnose whether it's electrical or mechanical failure. Sometimes it's a simple solenoid replacement. Sometimes the valve itself failed.
Why our approach matters: Some technicians replace the entire outdoor unit. Often we can fix just the reversing valve, saving you thousands.
Defrost Control Board Failure (Heat Pumps)
What causes it: Electrical problems, age, moisture damage, or control board failure.
What you'll notice: Outdoor unit ices up completely. System won't defrost. Eventually, it quits heating effectively.
How we fix it: Test the defrost controls, verify the defrost cycle is initiating, replace failed components.
Why our approach matters: We verify it's actually the defrost board before replacing it. Sometimes it's sensors or wiring, not the board.
Bad Contactor
What causes it: Electrical arcing, corrosion, overheating. Contactors wear out from repeated cycling.
What you'll notice: Clicking sound but AC won't start. Or AC starts randomly without the thermostat calling for it.
How we fix it: Replace the contactor. Simple part, quick fix if you've got it on the truck.
Why our approach matters: We inspect the wiring connections at the contactor. Sometimes it's not the contactor—it's a loose wire causing the problem.
Failed Ignitor (Gas Furnaces)
What causes it: Age and thermal cycling. Igniters crack or fail after years of heating and cooling.
What you'll notice: Furnace tries to start but won't ignite. You hear the blower but no heat.
How we fix it: Replace the ignitor. We carry common ignitors for major brands.
Why our approach matters: We test to confirm it's the ignitor before replacing it. Sometimes it's gas supply or valve problems.
Dirty or Failed Flame Sensor (Gas Furnaces)
What causes it: Soot buildup or sensor failure. Flame sensors detect when gas is actually burning.
What you'll notice: Furnace lights briefly then shuts off. Cycles repeatedly but won't stay lit.
How we fix it: Clean the flame sensor properly or replace if failed. Usually a quick fix.
Why our approach matters: We clean sensors correctly (specific technique required) and test to verify they're reading flame properly.
Bad Gas Valve (Gas Furnaces)
What causes it: Electrical failure, stuck valve, or age.
What you'll notice: Furnace won't ignite at all. Everything else seems to work, but no gas flows.
How we fix it: Test for power to the gas valve, verify gas supply, replace valve if needed.
Why our approach matters: We verify gas supply to the home first. Sometimes "bad valve" is actually a gas supply issue from the utility company.
Emergency Heat Stuck On (Heat Pumps)
What causes it: Thermostat problems, control board failure, or incorrect settings.
What you'll notice: House gets warm but power bill skyrockets. Emergency heat uses electric resistance heating—expensive.
How we fix it: Diagnose why emergency heat is engaging. Fix thermostats, controls, or settings.
Why our approach matters: Emergency heat should only run during defrost cycles or when it's extremely cold. If it's running constantly, something's wrong—and it's costing you money.
Low Refrigerant (Heat Pumps)
What causes it: Leaks from corrosion, vibration, poor installation, or age.
What you'll notice: Heat pump runs but doesn't heat well. Takes forever to warm the house. Outdoor unit may ice up.
How we fix it: Find the leak, repair it properly, evacuate the system, recharge with correct refrigerant amount.
Why our approach matters: Just adding refrigerant without fixing the leak wastes money. Refrigerant doesn't evaporate—if you're low, you've got a leak.
Blower Motor Problems
What causes it: Worn bearings, bad capacitor, electrical issues, or dirt accumulation.
What you'll notice: No airflow from vents even though heating system runs. Weak airflow. Strange noises.
How we fix it: Replace blower motor, capacitor, or repair electrical connections. Clean blower wheel if clogged.
Why our approach matters: We test capacitors and electrical before replacing the motor. Sometimes it's an easier fix.
Thermostat Issues
What causes it: Dead batteries, incorrect settings, failed thermostat, or bad wiring.
What you'll notice: Heating won't turn on, runs constantly, or temperatures are way off from the setting.
How we fix it: Test thermostat, check wiring, verify settings, replace if needed.
Why our approach matters: We verify it's the thermostat before replacing it. Often it's batteries or settings, not a failed thermostat.
Heat Exchanger Cracks (Gas Furnaces)
What causes it: Age, overheating, poor maintenance, or manufacturing defects.
What you'll notice: Sometimes no symptoms. Sometimes strange smells, soot, or high carbon monoxide levels.
How we fix it: This is serious—cracked heat exchangers can leak carbon monoxide. Usually requires furnace replacement.
Why our approach matters: We test for carbon monoxide and inspect heat exchangers during service. Your safety comes first.
Limit Switch Problems
What causes it: Restricted airflow, dirty filters, bad switch, or furnace overheating.
What you'll notice: Furnace shuts off before house is warm. Blower runs but heat doesn't.
How we fix it: Find why the limit switch is tripping (usually airflow restriction), fix the cause, replace switch if needed.
Why our approach matters: The limit switch is a safety device. We don't just bypass it—we fix why it's tripping.

FAQ - Heating Repair Questions
Heating repair costs depend on what's wrong. Simple fixes like thermostat replacement or cleaning flame sensors might run $150-$300+. Component replacement like igniters, reversing valve solenoids, or blower motors typically costs $300-$800+. Major repairs like compressor replacement can be $1,500-$3,000+. We provide clear pricing before starting work. During diagnosis, we'll explain what's wrong and what it costs so you can decide.
Most heating repairs are completed in 1-3 hours. Simple fixes (thermostat, ignitor, flame sensor) often take under an hour. More complex repairs (reversing valve, blower motor, defrost controls) might take 2-3 hours. If we need a special part, we'll complete what we can and return when the part arrives.
Yes. Most heating repair calls get same-day service, especially during cold snaps. We understand heating emergencies can't wait. Call (850) 994-5467 for fast service.
Heat pump blowing cold air usually indicates a stuck reversing valve, low refrigerant, defrost problems, or the system is actually in cooling mode (check thermostat). We'll diagnose the exact cause and fix it.
Common causes include failed ignitor, bad gas valve, dirty flame sensor, or gas supply problems. Most of these are fixable same-day. We'll diagnose which component failed.
If your system is less than 10 years old and repair costs less than half of replacement, repair usually makes sense. If you're facing expensive repairs on a 15+ year-old system, replacement often makes more financial sense. We'll give you honest advice.
Annual maintenance is recommended. Fall tune-ups before winter prepare your system for heating season. Regular service prevents most breakdowns.
Yes. Heat pumps are ideal for Florida's climate. They provide efficient cooling most of the year and adequate heating for our mild winters. They're the most common HVAC system in Northwest Florida.
Emergency heat bypasses the heat pump and uses electric resistance heating. It's expensive but provides heat when the heat pump isn't working. Don't run emergency heat constantly—call for repair.
Outdoor unit icing is normal during defrost cycles, but constant freezing indicates defrost control problems. The system should periodically defrost itself. If it stays frozen, something's wrong.
Yes. We service heat pumps (most common), gas furnaces, electric furnaces, and dual fuel systems throughout Northwest Florida.
We're licensed electrical contractors (EC13014513). We diagnose and fix both HVAC and electrical issues—one company, complete solution.
