What are common furnace problems in Pooler GA?

Common furnace problems include no heat (thermostat or ignitor failure), short cycling (dirty filter or faulty limit switch), strange noises (blower motor issues), weak airflow (clogged filter or blower problems), and yellow pilot light (ventilation problem requiring immediate service).

How much does furnace repair cost in Pooler GA?

Furnace repair costs $200-900. Thermostat replacement costs $150-400. Ignitor replacement costs $150-300. Blower motor repair costs $300-600. Heat exchanger replacement costs $600-900. Most repairs take 1-3 hours.

Why does my furnace keep turning on and off?

Furnace short cycling is usually caused by dirty air filters, faulty limit switches, or thermostat problems. Dirty filters block airflow causing overheating. Limit switches shut system down when temperature gets too high. Cost to fix: $75-400.

Furnace Repair: Common Problems & Costs

What causes furnace problems in Pooler GA and typical repair costs.

Most common furnace problems: no heat (thermostat/ignitor, $150-400), short cycling (filter/limit switch, $75-400), strange noises (blower motor, $300-600). Average repair time: 1-3 hours.

No Heat

When furnace runs but produces no warm air, or doesn't turn on at all.

Common Causes

Thermostat problems: Wrong setting, dead batteries, or faulty wiring
Failed ignitor: Won't light gas (most common on systems 5+ years old)
Flame sensor dirty: Safety feature shuts down burner incorrectly
Gas valve failure: No gas reaches burner even when ignitor works

Repair Costs

Thermostat replacement	$150-400
Ignitor replacement	$150-300
Flame sensor cleaning	$75-200
Gas valve replacement	$300-500

Short Cycling

Furnace turns on for 2-3 minutes then shuts off, repeats constantly.

Common Causes

Dirty air filter: Blocks airflow causing overheating protection to trigger
Faulty limit switch: Shuts system down prematurely
Oversized furnace: Heats space too quickly (requires replacement)
Thermostat location: Too close to heat source giving false readings

Repair Costs

Filter replacement	$20-75
Limit switch replacement	$150-300
Thermostat relocation	$200-400

Strange Noises

Grinding, squealing, or banging sounds from furnace.

Noise Types & Causes

Grinding: Blower motor bearings worn out
Squealing: Belt slipping or blower motor issue
Banging: Delayed ignition causing gas buildup (safety concern)
Rattling: Loose panels or ductwork

Repair Costs

Blower motor repair	$300-600
Belt replacement	$100-200
Panel/ductwork securing	$75-150

Weak Airflow

Little to no air coming from vents even when furnace is running.

Common Causes

Clogged filter: Most common cause, easiest fix
Blower motor failure: Motor runs but fan doesn't spin properly
Ductwork leaks: Air escaping before reaching vents
Blocked registers: Furniture or debris blocking vents

Repair Costs

Filter replacement	$20-75
Blower motor replacement	$300-600
Duct sealing	$200-500

Yellow Pilot Light (Safety Issue)

Pilot light should be blue. Yellow or orange flame indicates incomplete combustion and possible carbon monoxide risk. Turn off furnace and call for immediate service. Cost to fix: $200-500.

Pooler GA Climate Factors

Pooler's mild winters mean furnaces cycle less frequently than northern climates. This can cause:

First-use failures: Systems sit idle for months, dust and corrosion accumulate
Heat pump preference: Many Pooler homes use heat pumps instead of furnaces
Humidity concerns: High moisture can cause rust in unused components
