Frequently Asked Questions
How much does gas furnace repair cost in Milwaukee?
Gas furnace repair in Milwaukee costs $100-$400 for common issues (ignitor, thermocouple, blower motor). Heat exchanger replacement costs $500-$1,500. Diagnostic fee is $75-$150, usually applied to repair.
Why is my gas furnace not heating?
Common causes: dirty filter restricting airflow, faulty ignitor or pilot light, bad thermostat, tripped safety switch, or gas supply issue. Check the filter and thermostat first — these fix 30% of no-heat calls.
Is a cracked heat exchanger dangerous?
Yes — a cracked heat exchanger can leak carbon monoxide into your home. If diagnosed, shut off the furnace immediately. Replacement costs $500-$1,500 but if the furnace is 15+ years old, full replacement is usually more cost-effective.
