Common Warning Signs You Need Furnace Repair
Recognizing early performance degradation prevents minor electrical or airflow faults from turning into catastrophic compressor burnout. If you observe any of the following symptoms in your Cumming residence, schedule service immediately:
Furnace Blowing Cold Air
Usually caused by a failed electronic ignitor, dirty flame sensor rod causing safety lockout, or a tripped high-limit switch from a clogged air filter.
Furnace Clicks Repeatedly but Won't Ignite
Indicates a weak hot surface ignitor, faulty gas supply valve, defective flame rectification circuit, or blocked pressure switch port.
Yellow or Flickering Burner Flames
Gas burners should burn a crisp, steady blue. Yellow or lazy flickering flames indicate incomplete combustion and potential carbon monoxide production.
Loud Banging or Booming on Startup
Delayed ignition caused by dirty burner ports allowing gas to build up in the combustion chamber before violently igniting.
Frequent Short-Cycling
The furnace shuts down after 2 to 3 minutes because of an overheating heat exchanger, restricted return airflow, or a malfunctioning thermostat.
Continuous Blower Motor Running
The indoor fan runs non-stop due to a stuck limit switch relay, manual thermostat fan setting, or control board failure.
Our Step-by-Step Furnace Repair Workflow
Combustion & Electrical Safety Triage
We inspect gas line pressure, test flame sensor microamps, verify draft inducer draft pressure, and test high-limit safety switches.
Heat Exchanger Inspection & CO Testing
We perform video scope inspections of the heat exchanger to verify zero cracks or rust pinholes and test ambient carbon monoxide levels.
Precision OEM Component Repair
We replace failed ignitors, clean burner orifices, calibrate gas manifold pressures to manufacturer specs, and replace worn blower motors.
Operational Run & Temperature Rise Test
We verify burner ignition sequence, measure supply air temperature rise against the unit data plate, and test thermostat shut-off.
