Heating season in Cut Off and the rest of South Lafourche is short, and that is exactly what makes it risky. A system that sat unused from March through November has had eight or nine months for a capacitor to weaken, a heat strip to corrode, or a rodent to chew through low voltage wire. Nobody finds out until the first cold front pushes through and the thermostat calls for heat that never arrives. Martin’s A/C and Electric has been working on heating equipment along the bayou since 1967, and we still get most of our December calls from homes that ran fine the previous winter.
Why Heating Systems Fail Along the Bayou
Most homes we service run a heat pump with electric backup rather than a gas furnace, so heating problems here rarely look like the ones described in national troubleshooting guides. A heat pump has to reverse its refrigerant flow to make heat, which means a fault in the reversing valve, the defrost board, or the outdoor coil shows up only when you need warmth. Add salt-laden air that pits contactors and disconnects, plus humidity that keeps attic air handlers damp, and you get a system that passes a summer cooling check and still cannot hold 70 degrees in January.
The other pattern we see constantly is leaking or undersized duct. If your ductwork has been patched over the years, warm air is heating your attic before it ever reaches the bedrooms. That is a duct design problem rather than a furnace problem, and new equipment will not fix it.
Heating Repairs We Handle Most Often
- Heat pumps that blow cool air, run constantly, or never leave defrost mode.
- Electric heat strips and sequencers that stopped energizing.
- Gas furnace ignition faults, flame sensors, and rollout switches.
- Blower motors, capacitors, and failed control boards.
- Thermostats wired or programmed incorrectly during a previous repair.
- Outdoor units iced over or flooded after a hard freeze.
We quote the repair before we start it. If a part is common on South Louisiana equipment, it is already on the truck, which is how most heating calls finish in a single visit.
Signs to Call Before the First Cold Night
Heating problems announce themselves early if you know what to listen for. Call us if the system takes more than a few minutes to put out warm air, if you hear grinding or a metallic scrape when the blower starts, if you smell burning past the first ten minutes of runtime, if breakers trip when the backup heat engages, or if one room never catches up to the rest of the house. A burning smell that keeps coming back is worth shutting the system off over, because it usually means a heat strip or a wire connection is running hotter than it should. Musty air when the heat kicks on points at the air handler or the filter, which ties back to indoor air quality more than to the heat itself.
When Repair Stops Making Sense
We do not push replacement on equipment that still has life in it. A ten year old heat pump with a failed capacitor is worth repairing. The same unit with a leaking coil, a tired compressor, and climbing power bills usually is not, and we will put the numbers in front of you instead of asking you to take our word for it. When replacement is the right call, we size the new system with a load calculation rather than matching whatever was there before, because oversized equipment short cycles and leaves the house humid. Plenty of customers pair a heating replacement with an air conditioning upgrade, since it is the same equipment doing both jobs.
