Furnace Repair & Installation FAQ for Jacksonville Homeowners

How often should Jacksonville homeowners get furnace repair & installation?
Given Jacksonville's hot, humid summers averaging 90°f with afternoon thunderstorms, most homeowners benefit from furnace repair & installation at least once a year. Year-round roof algae removal from heat and humidity often makes spring or fall the optimal time to schedule service.
What home types in Jacksonville most need furnace repair & installation?
CBS concrete block and stucco homes throughout Duval County and Ranch homes in suburban St. Johns County are the most common home types in Jacksonville and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
Why is my furnace not heating?
Common causes: dirty air filter, failed igniter or flame sensor, tripped limit switch, thermostat issue, gas supply problem, or failed inducer motor. A technician will diagnose the specific fault.
Is a cracked heat exchanger dangerous?
Yes. A cracked heat exchanger can allow combustion gases including carbon monoxide to enter living spaces. It's a serious safety hazard that requires immediate furnace repair or replacement.
How long do furnaces last?
Gas furnaces last 15–20 years with regular maintenance. Oil furnaces last 20–25 years. Electric furnaces last 20–30 years. Plan for replacement when repair costs approach half the replacement cost.
What is AFUE and why does it matter?
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel to heat. A 96% AFUE furnace wastes only 4 cents of every dollar of fuel. Older furnaces may be 60–70% efficient, so upgrades reduce heating costs significantly.
