Most Livingston Parish and Baton Rouge homes are well-suited to a high-efficiency heat pump — our winters simply aren't cold enough, often enough, to justify the premium cost of a high-BTU gas furnace for most families. That said, every home is different; we size with Manual J, not with a guess, and we'll walk you through real operating cost math before you spend a penny.
Why upgrade your heating system
Your furnace is 15+ years old
Old 80% AFUE furnaces waste 20 cents of every heating dollar. Modern 95%+ condensing furnaces pay back the upgrade in under six years for most Baton Rouge homes.
You have R-22 or an old heat pump
R-22 heat pumps are at end-of-life — the refrigerant is scarce and expensive. Upgrading to R-410A or R-32 cuts your winter bill and qualifies you for rebates.
Your home has cold spots
Undersized ductwork or wrong-capacity equipment causes uneven heating. New installations include airflow balancing.
Loud operation
Old single-stage furnaces run at full blast until they shut off. Modern two-stage and variable-speed systems run quietly for long cycles — better comfort, better humidity control.
Poor indoor air quality
A new high-MERV filter cabinet or whole-home dehumidifier can transform how your house feels, especially in Louisiana's spring-pollen and summer-humidity months.
You want lower bills and predictable comfort
Modern variable-speed heat pumps cost roughly half what a gas furnace costs to operate per BTU in our climate — and they handle cooling too.
