New Orleans sits in USDA Hardiness Zone 9a, and the winters here are genuinely mild by national standards. Average low temperatures in December hover around 48 degrees Fahrenheit, January lows average about 46 degrees, and February lows run near 50 degrees. For most of the country, those are cool autumn temperatures. But for New Orleans residents accustomed to summer heat and humidity, a night in the mid-40s feels biting, and the city’s famously high relative humidity makes it feel even colder than the thermometer reads. A 45-degree night with 80% humidity feels closer to 35 degrees to the human body.
The real challenge for heating systems in the New Orleans area is not sustained cold, it is sudden cold. A system that has been sitting idle since March can be called on with almost no warning when a cold front pushes down from the north. The first cold spell of the season is also the most likely time for a heating failure, because components that have been dormant for six to eight months can fail under the sudden demand.
Compounding this is the Gulf Coast climate itself. High relative humidity, salt air in neighborhoods close to Lake Pontchartrain and the Mississippi River Gulf Outlet, and the long stretches of high-heat, high-humidity operation that the cooling season demands all place stress on HVAC components year-round. Capacitors, contactors, coils, and refrigerant connections all age faster in this environment than they would in a drier, more temperate climate.
This is why annual heating maintenance before winter, rather than a call for emergency repair during the first cold night, is the smartest investment a New Orleans homeowner can make. But when the system fails, Big Easy Air Conditioning is ready to respond.
Heat pumps are by far the most common heating system in New Orleans and throughout southeast Louisiana. Because they operate on the same refrigeration cycle as central air conditioning, heat pumps are ideal for a climate where cooling far outnumbers heating hours. A well-sized heat pump handles both summer cooling and winter heating in one unit, avoiding the need for a separate furnace. In mild winters like New Orleans typically experiences, heat pumps operate at very high efficiency, often delivering two to three units of heat energy for every unit of electrical energy consumed.
When a heat pump stops heating, the cause is almost always one of the following:
The reversing valve is the component that switches refrigerant flow direction, allowing the system to operate in cooling mode in summer and heating mode in winter. When the reversing valve fails, the system can get stuck in cooling mode, continuing to push cold air even when the thermostat is set to heat. Reversing valve failure is one of the more involved heat pump repairs, requiring a trained technician with refrigerant handling certification. Replacement typically costs $400 to $950 including parts and labor.
A heat pump that is low on refrigerant cannot effectively transfer heat. In cooling mode, this results in warm air from the vents. In heating mode, you get inadequate warmth even when the system is running. Low refrigerant always indicates a leak somewhere in the system. Simply adding refrigerant without finding and sealing the leak is a temporary fix that will fail again. A proper repair includes leak detection, leak sealing or component replacement, and recharging to the manufacturer’s specified pressure.
Capacitors provide the electrical start-up burst that gets the compressor and fan motors running. Contactors are the electrical switches that energize the compressor and condenser fan. Both components wear out over time, especially in the high-heat environment inside an outdoor unit during a New Orleans summer. A failed capacitor often causes the system to hum but fail to start, or to start and quickly trip the breaker. Capacitor replacement is one of the less expensive heat pump repairs, typically $150 to $350.
In cold, humid conditions common to New Orleans winters, frost can accumulate on the outdoor coil. This is normal, and heat pumps are designed to run periodic defrost cycles to clear the ice. If the defrost board or defrost thermostat fails, the system cannot clear the ice, and the coil becomes encased in a block of ice that prevents heat transfer entirely. A technician can diagnose defrost system failures and replace the relevant components.
Before assuming the heat pump itself has failed, always verify thermostat settings and function. A thermostat set to Cool instead of Heat, a thermostat with dead batteries, or a failed thermostat communication board can all prevent the system from heating even when the heat pump itself is in perfect condition. Thermostat replacement is typically $150 to $400 depending on the unit.
While heat pumps dominate the New Orleans market, gas furnaces are installed in some homes, particularly those with existing gas service from Entergy New Orleans or Centerpoint Energy, older homes that were originally built with central gas heat, and homes with dual-fuel systems that pair a heat pump with a gas furnace backup. Gas furnaces are highly effective when temperatures drop below the efficient operating range of a heat pump, which is roughly below 30 to 35 degrees Fahrenheit.
Common gas furnace repairs in the New Orleans area include:
Modern gas furnaces use an electronic igniter rather than a standing pilot light. The igniter heats to extreme temperatures to light the burners. Over time, igniters become brittle and crack. A failed igniter means the burners cannot light, so the furnace runs the blower but delivers no heat. Igniter replacement is typically $150 to $350 and is among the most common furnace repairs.
The heat exchanger is the metal component that separates combustion gases from the air your family breathes. A cracked heat exchanger allows carbon monoxide and other combustion byproducts to enter the living space, which is a serious safety hazard. Signs include a yellow or flickering burner flame instead of a steady blue flame, soot accumulation, a metallic or burning smell when heat runs, and in severe cases, symptoms of carbon monoxide exposure such as headaches and dizziness. Any suspected heat exchanger crack requires immediate shutdown and professional inspection.
The blower motor circulates heated air through the ductwork. A failing blower motor may run slowly, make grinding or squealing noises, or stop functioning altogether. Blower motor replacement costs $300 to $600 depending on the motor size and accessibility.
The gas valve controls fuel flow to the burners. A faulty gas valve may fail to open (no heat) or fail to close properly (a safety hazard). Gas valve replacement typically costs $200 to $600 and must be performed by a licensed technician.
The flame sensor confirms that the burners have successfully ignited. If the sensor becomes coated with residue, it cannot detect the flame and shuts the furnace down as a safety measure. Cleaning or replacing a flame sensor is typically a quick, inexpensive repair in the $80 to $200 range.
A severely clogged air filter restricts airflow to the point where a furnace overheats and shuts down on a thermal limit switch. This is one of the most common causes of a no-heat call and one of the most avoidable. Replacing the filter may restore normal operation, but if the furnace has been overheating repeatedly, the thermal limit switch itself may need to be reset or replaced.
Regardless of system type, heating problems in New Orleans homes tend to cluster around a handful of recurring issues. Understanding what these look and feel like helps you communicate clearly with a technician and understand the diagnosis.
Check the thermostat mode (set to Heat, not Cool), the thermostat temperature setpoint (must be above current room temperature), the circuit breakers for both the air handler and outdoor unit, and the filter. If all of those check out, the problem is a component failure requiring professional diagnosis.
Short cycling means the system turns on briefly and shuts off before completing a full heating cycle. Common causes include an oversized system (produces too much heat too fast), a clogged filter causing overheating, a failing thermostat, low refrigerant charge on a heat pump, or a tripped limit switch. Short cycling not only fails to heat the home effectively but stresses the compressor and reduces equipment life.
The system runs but the home never reaches the set temperature. In New Orleans, this is often the first sign of a heat pump problem, because mild winters mask declining efficiency. By the time a really cold front arrives, the low refrigerant charge, failing capacitor, or partially stuck reversing valve that has been causing gradual efficiency loss becomes obvious.
Grinding indicates worn bearings in a blower motor or fan motor. Squealing is usually a belt (in older systems) or a motor bearing starting to fail. Banging or clanking suggests a loose component inside the air handler or outdoor unit. Clicking that repeats without the system starting often indicates a failing contactor or relay. None of these sounds are normal, and all warrant a service call before the problem escalates.
Replace batteries first. If the thermostat still does not respond, check whether the system works when operated from a backup thermostat or a temporary bypass. A failed thermostat is a relatively inexpensive fix but it can mimic a wide range of system failures.
A heating system that repeatedly trips the circuit breaker is drawing more amperage than it should, which signals a failing motor, a compressor starting to seize, a short in the wiring, or a severe restriction in airflow. Resetting the breaker once and monitoring is fine. If it trips again, do not reset it again, call for service. Repeatedly resetting a breaker can damage the electrical panel and risks a fire.
New Orleans cold fronts do not announce themselves courteously. A 70-degree afternoon in December can be followed by a 38-degree morning, and if your heating system has not been tested since last winter, that overnight cold snap becomes an emergency. Big Easy Air Conditioning provides emergency heating repair throughout the greater New Orleans area, including Metairie, Kenner, Gretna, Chalmette, Slidell, the Northshore, Mandeville, Madisonville, and Hammond.

| Control board replacement | $400 to $900 |
Emergency or after-hours service carries an additional diagnostic fee on top of parts and labor. Most diagnostic visits include a full system evaluation so you understand not just the immediate failure but the overall condition of your heating system.
Every homeowner eventually faces the repair-versus-replace decision. Here are the factors that consistently point toward replacement over repair:
Heat pumps have an average lifespan of 15 to 20 years in moderate climates. New Orleans systems often reach the lower end of that range due to the extended cooling seasons and corrosive humidity. A heat pump over 12 years old that needs a major component repair is a strong candidate for replacement, because other components are also near the end of their useful life.
If the repair cost exceeds 30% of the price of a comparable new system, replacement is generally the better investment. A new heat pump delivers higher efficiency (HSPF2 and SEER2 ratings have improved significantly in recent years), comes with a manufacturer’s warranty, and will not need another major repair in the near term.
Two or more significant repairs in a single season is a strong signal that the system is in general decline. You may spend more in cumulative repairs over the next two years than a replacement would cost today.
A heating system that is losing efficiency works harder and longer to deliver the same amount of heat. If your Entergy New Orleans bills have been climbing without a corresponding increase in usage, declining system efficiency may be the culprit.
Systems manufactured before 2010 may use R-22 refrigerant, which is no longer produced in the United States. If your heat pump uses R-22 and develops a refrigerant leak, repair costs are extremely high due to R-22 scarcity. Replacement with a modern R-410A or R-32 system is almost always the correct economic decision.
Do not wait for a complete breakdown to call for service. These warning signs indicate a developing problem that will worsen, and addressing it now costs less than an emergency call during a cold snap:
When you call Big Easy Air Conditioning for a heating repair, a licensed technician arrives with a fully stocked service vehicle carrying the most common replacement parts for heat pumps, furnaces, and ductless systems. The technician begins with a full system diagnostic, checking electrical components, refrigerant pressure, thermostat calibration, airflow, and combustion safety (for gas furnaces) before identifying the root cause of the failure.
You receive a clear explanation of what failed, what caused it, and what the repair entails before any work begins. If the repair makes financial sense relative to the system’s age and condition, the technician completes it on the spot whenever parts are available. If the diagnosis suggests replacement is the better option, you receive an honest assessment with no pressure.
We service all major heat pump and furnace brands including Carrier, Trane, Lennox, Rheem, York, Goodman, American Standard, Mitsubishi, Daikin, and Fujitsu.

Heating repair in New Orleans typically ranges from $150 to $950 depending on the component and system type. Minor repairs like capacitors, igniters, or flame sensors run $80 to $350. Blower motors cost $300 to $600. Reversing valves on heat pumps are $400 to $950. Emergency after-hours service carries an additional diagnostic fee on top of parts and labor.
The most common reasons a heat pump stops heating include a failed reversing valve, low refrigerant charge, a bad capacitor or contactor, a frozen outdoor coil that is not completing its defrost cycle, or a faulty thermostat. Because New Orleans heat pumps often sit idle for 6 to 8 months between uses, component failures discovered during the first cold spell of the season are common.
Signs include a yellow or flickering flame instead of steady blue, a burning or sulfur smell when heat runs, soot buildup inside the furnace cabinet, and symptoms like headaches or dizziness in family members when the heat is on. A cracked heat exchanger is a carbon monoxide risk and requires immediate system shutdown and professional inspection.
Common issues include heat pumps stuck in cooling mode due to a failed reversing valve, short cycling from clogged filters or oversized systems, no heat due to tripped breakers or bad thermostats, strange noises from failing motors or bearings, and insufficient heat from low refrigerant or blocked airflow. Most problems surface during the first cold snap after months of system inactivity.
If the repair costs more than 30% of the price of a comparable new system and the unit is over 10 to 12 years old, replacement is usually the better investment. Repeated breakdowns in a single season, rising utility bills, or an R-22 refrigerant system with a refrigerant leak all strongly favor replacement over repair.
Yes. High humidity accelerates corrosion on coils and electrical contacts, salt air near the lake and river can corrode outdoor unit fins, and long periods of disuse during the warm months cause capacitors and contactors to fail prematurely. The extended cooling season in New Orleans also adds runtime hours that age the compressor faster than in colder climates where heating and cooling hours are more balanced.
Yes. Most modern heat pumps extract heat from outdoor air down to about 25 to 30 degrees Fahrenheit before efficiency drops significantly. Since New Orleans rarely drops below freezing, heat pumps work well as the sole heating source here. The outdoor coil will frost over in cold, humid conditions, and the system runs automatic defrost cycles to clear the ice. If defrost cycles are not working, the outdoor coil can ice over completely, requiring a service call.
The reversing valve is the component that allows a heat pump to switch between heating and cooling mode by reversing refrigerant flow direction. When it fails, the system gets stuck in one mode, most often cooling mode, delivering cold air even when set to heat. Reversing valve replacement is one of the more costly heat pump repairs at $400 to $950 including parts and labor.
Most repairs take 1 to 3 hours. Quick fixes like capacitor or thermostat replacement take under an hour. More involved work like reversing valve replacement, blower motor replacement, or refrigerant leak detection and recharge takes 2 to 4 hours. If a part needs to be ordered, completion depends on parts availability, typically same-day or next-day for common components.
Check that the thermostat is set to Heat mode and set above room temperature, verify the circuit breakers for the air handler and outdoor unit have not tripped, and replace the air filter if it has not been changed recently. A clogged filter is one of the top causes of heating system shutdowns. If these steps do not restore heat, call a licensed technician.
