Common Furnace Problems We Fix
Recognize one of these? We’ve seen it thousands of times and know exactly how to fix it.
Furnace Not Heating
A furnace that runs but doesn’t heat is usually caused by a faulty ignition, dirty filter, thermostat issue, or gas supply problem. Our technicians diagnose the exact cause and restore heat — usually in a single visit.
Furnace Won't Turn On
Check your thermostat batteries and breaker first. If those are fine, the issue may be a faulty control board, blower motor, or safety switch. Call us for a same-day diagnostic
Strange Furnace Noises
Banging, rattling, squealing or humming usually indicates worn belts, loose components, or motor problems. These should be addressed quickly to prevent expensive damage.
Weak Airflow
Weak airflow is often caused by a clogged filter, blocked ducts, or a failing blower motor. We’ll inspect the full system and restore proper airflow throughout your home.
Pilot Light Problems
Pilot light issues can stem from a faulty thermocouple, draft, or dirty pilot orifice. For safety, gas-related issues should always be handled by a licensed technician.
High Energy Bills
Rising bills often point to an aging furnace, dirty components, or poor maintenance. A tune-up can dramatically improve efficiency or it may be time to consider replacement.
Uneven Heating
Cold rooms usually indicate ductwork problems, zoning issues, or an undersized furnace. We’ll balance airflow and recommend the right long-term fix.
Thermostat Issues
If your thermostat is unresponsive or the temperature reading is off, it may need recalibration, new batteries, or replacement with a modern smart thermostat.
