Heating Systems We Repair

Most Northshore homes heat with either a gas furnace or a heat pump, and many newer homes use a dual-fuel setup that combines both. We repair them all:

  • Gas furnaces: ignition, flame sensor, gas valve, blower, and heat exchanger problems. See our dedicated furnace repair page for details.
  • Heat pumps: refrigerant leaks, reversing valves, defrost controls, capacitors, and compressors
  • Electric furnaces and air handlers: heat strips, sequencers, relays, and blower motors
  • Dual-fuel systems: controls that switch between heat pump and gas backup
  • Ductless mini-splits in heating mode, through our mini-split repair service
  • Geothermal heat pumps and the loop and pump components that support them
  • Thermostats and the wiring that tells your system when to run

Signs Your Heater Needs Repair

Small problems get bigger the longer they run. Call for service if you notice any of these:

  • The system won’t turn on, or it starts and shuts off without heating
  • Weak or uneven heat, with some rooms warm and others cold
  • Cool or lukewarm air from the vents when the thermostat calls for heat
  • Banging, squealing, grinding, or rattling from the furnace, air handler, or outdoor unit
  • An outdoor heat pump unit that stays coated in ice
  • The “aux” or “emergency heat” light staying on in mild weather
  • A burning smell that lingers past the first few minutes of the season
  • Energy bills that spike even though your usage hasn’t changed

If you smell gas or your carbon monoxide alarm sounds, leave the home right away and call for help from outside.

Common Heat Pump Problems on the Northshore

Heat pumps are popular here because they cool all summer and heat efficiently through our mild winters. Because they run year-round, they also see more wear than a furnace that only works a few weeks a year. These are the issues we repair most often:

  • Low refrigerant from a leak, which cuts heating output and strains the compressor
  • Stuck reversing valves that leave the system blowing cool air in heat mode
  • Failed defrost controls that let ice build up on the outdoor coil
  • Bad capacitors and contactors, a common failure after a long, hot summer
  • Auxiliary heat problems that cause high bills or weak heat during a freeze


A heat pump that is struggling will often lean on its backup electric heat, which quietly drives up your power bill. Catching the problem early protects both your comfort and your wallet.

What to Expect During Your Heater Repair Visit

Our process is built so you always know what is happening and what it will cost:

  1. Fast scheduling. Call (985) 200-5442 or book online. Same-day and emergency appointments are available.
  2. A full-system diagnosis. Your technician checks the thermostat, wiring, airflow, and filter, then tests the components specific to your system: burners, ignition, and heat exchanger on a furnace, or refrigerant charge, reversing valve, and defrost controls on a heat pump.
  3. A clear explanation. We show you what we found in plain language, without pressure.
  4. Upfront pricing. You approve the price before any work begins.
  5. The repair. We use quality parts and carry common components on our trucks, so most repairs are done in one visit.
  6. Testing and safety checks. We run your system through a full heating cycle and confirm every safety control works.
  7. A walkthrough. We review the work and share tips to keep your heater running well.


Every repair is backed by our satisfaction guarantee, and we are a phone call away if anything comes up later.

How Northshore Winters Affect Your Heater

Heating season here is short, but it is not gentle every year. Cold fronts in December and January can drop mornings into the 30s, and an occasional hard freeze sends every heater in St. Tammany and Tangipahoa Parish running at full output at once. That is when weak systems fail and repair schedules fill up.

Furnaces face a different problem than heat pumps. A gas furnace may sit idle for eight months while humidity and dust build up on its flame sensor, burners, and wiring, so it fails on the first cold night. A heat pump works hard all summer, so worn capacitors, low refrigerant, and tired motors often show up the moment it switches to heat.

A fall heater tune-up catches most of these issues before the first cold front, when scheduling is easier and the fix is usually smaller.

Repair or Replace? Honest Advice

Most heating problems can be repaired. If your system is in good shape and the repair cost is reasonable, fixing it is usually the right call, and we will never push a new system when a repair will serve you well.

Replacement starts to make sense when a furnace is 15 or more years old, a heat pump is past 10 to 12 years and needs a major part like a compressor, or you are paying for repairs every season. In that case, we will walk you through your heating replacement and new heating installation options, along with flexible financing, so you can decide with clear information.

Heater Repair in Northshore, LA FAQs​

It depends on your system and what failed. Common fixes like an igniter, flame sensor, capacitor, or thermostat are on the lower end. Larger repairs like a blower motor, control board, reversing valve, or refrigerant leak cost more. Your Southern Air technician diagnoses the problem first and gives you an upfront price before any work starts, and our No Surprise Guarantee means the quote is what you pay.
Yes. We repair gas furnaces, electric furnaces, heat pumps, dual-fuel systems, ductless mini-splits, and geothermal heat pumps across all major brands. Our technicians also repair the thermostats, wiring, and ductwork that keep those systems running.
A few things cause this. Your heat pump may be in a normal defrost cycle, which only lasts a few minutes. If it continues, the cause is often low refrigerant, a stuck reversing valve, a failed defrost control, or a thermostat set to the wrong mode. If the air stays cool for more than 15 minutes, call us for a diagnosis.
When a heat pump can’t keep up, it leans on auxiliary electric heat strips, which use far more power. Some reliance on backup heat is normal during a hard freeze. If the “aux” or “emergency heat” light stays on during milder weather, your heat pump likely needs repair.
Yes. Southern Air provides emergency heating repair across the Northshore, and our phones have 24/7 live answering. If your heat goes out during a cold snap or freeze, call (985) 200-5442 and a real person will help get a technician on the way.
