HEAT PUMP SERVICE IN HATTIESBURG · WHY LOCALS CALL KEITH'S

Repair in one visit. Install in one day. 10-year parts warranty, 1-year labor. That standard applies whether you're in Downtown Hattiesburg, Oak Grove, or anywhere else in Hattiesburg.

Hattiesburg is our largest inland market. Winters here are noticeably colder than the Coast, so heat pump and furnace demand is much higher year-round. Student rentals near USM and William Carey drive volume for smaller repair jobs and quick turnarounds. Commercial demand from restaurants, retail near Turtle Creek Mall, and medical near Forrest General Hospital. Newer construction in Oak Grove skews standard efficient residential.

Heat Pump Service in Hattiesburg covers these ZIP codes: 39401, 39402, 39406. We service homes near The University of Southern Mississippi, William Carey University, Downtown Hattiesburg, and every neighborhood between.

HATTIESBURG HEAT PUMP SERVICE
QUESTIONS ANSWERED.

Why does my heat pump run auxiliary heat so often?

Either the outdoor coil is dirty, the defrost cycle failed, refrigerant is low, or the aux heat is set to kick in too aggressively at the thermostat. We diagnose the actual cause instead of just charging refrigerant.

Do heat pumps work in Mississippi winters?

Perfectly. Modern heat pumps maintain full capacity down to about 25°F and keep working (with auxiliary heat assist) below that. Coast winters rarely test the equipment.

How often should I service my heat pump?

Twice a year: spring cooling tune-up and fall heating tune-up. Both are covered by the Keith's Care Plan at $199.99 annually.
