Here’s what you need to know.
Because winters in Acadiana are mild, many heating systems sit unused for months. When the temperature suddenly drops, problems show up fast.
Common causes include:
•Tripped breakers or blown fuses
•Dirty or clogged air filters
•Thermostat settings still set for cooling
•Worn ignition components
💡 Tip: Test your heater before the first cold front hits to avoid no-heat emergencies.
This is one of the most common winter calls we get — and often one of the least serious.
What’s usually happening:
Dust has settled on heat exchangers or burners
The smell burns off within the first 10–30 minutes
When it’s a problem:
Strong electrical smells
Persistent burning odors
Smoke or visible sparks
If the smell doesn’t go away quickly, turn the system off and call a professional.
Many Acadiana homes rely on heat pumps, which work differently than gas or electric furnaces. Common winter heat pump issues include
•System stuck in cooling mode
•Defrost cycle confusion (steam from outdoor unit)
•Weak airflow or lukewarm air
Because heat pumps pull warmth from outdoor air, cold, damp Louisiana mornings can expose performance issues quickly.
Winter systems here don’t run long, which can cause:
•Short cycling (system turns on and off rapidly)
•Cold spots in certain rooms
•Poor airflow
These issues are often tied to:
•Dirty filters
•Improper thermostat placement
•Ductwork problems
•Oversized systems common in older Acadiana homes
Many homeowners are surprised when their energy bills spike during cold months.
Common reasons include:
•Running emergency heat unknowingly
•Dirty filters restricting airflow
•Aging or inefficient systems
•Poor insulation common in older Louisiana homes
A winter tune-up can often lower heating costs immediately.
If your heater is making strange noises, producing odors, or not keeping your home comfortable, don’t wait.
