Common Signs Your Furnace Needs Repair
Furnace problems in cold weather are more than an inconvenience. Watch for these common warning signs and call PECO Heating & Cooling when you notice them. Many furnace problems involve gas, electrical, or combustion parts, so we don’t recommend DIY repairs beyond the simple checks below.
No Heat or Cold Air from the Vents
If your furnace is blowing cold air or no heat at all, start with two simple checks. First, make sure the thermostat fan is set to “auto” instead of “on.” When the fan is set to “on,” the blower runs constantly and pushes room-temperature air through the vents between heating cycles. Next, check the air filter. A clogged filter restricts airflow, which can cause the furnace to overheat and shut off its burners while the blower keeps running. If neither check solves the problem, a dirty flame sensor or an ignition problem may be the cause. Call us to schedule a furnace repair visit.
Banging, Squealing, or Rattling Noises
Loud banging when your furnace starts is often caused by delayed ignition or dirty burners. When ignition is delayed, gas builds up in the combustion chamber and lights all at once. Over time, this can damage the furnace and crack the heat exchanger, which can allow carbon monoxide into your home. Squealing usually points to worn blower motor bearings, an old fan belt, or restricted airflow from a clogged filter. Rattling can mean loose panels or parts. Light popping as the ductwork warms up and cools down is usually normal. If you hear banging or new, loud noises, call us right away. Regular heater maintenance with a PECO Comfort Club maintenance plan helps catch these problems early.Short Cycling or Frequent Shut-Offs
If your furnace turns on and off frequently without warming your home, it is short cycling. Common causes include a clogged air filter, a dirty flame sensor, an overheating furnace, a thermostat problem, or a system that isn’t sized correctly for the home. Short cycling puts extra wear on furnace parts, wastes energy, and leaves rooms uncomfortable. A PECO technician can find the cause and recommend the right fix, whether that’s a simple furnace repair or an honest conversation about replacement.Uneven Heat or Rising Heating Bills
When some rooms stay cold while others feel warm, or your heating bills keep climbing without a change in how you use your system, your furnace may not be running the way it should. Possible causes include a dirty filter, a weak blower motor, blocked or leaking ductwork, thermostat problems, or worn parts that make the furnace work harder. A furnace repair visit can find the cause and fix it, and routine heater maintenance helps keep your system running evenly and efficiently all season.Burning, Smoky, or Gas Odors
A faint burning-dust smell when you first turn on your furnace is common. It comes from dust that settled on the furnace over the summer and usually fades once the system has run for a while. A burning plastic or rubber smell can mean an overheating blower motor or a wiring problem, which can be a fire risk. A smoky smell can point to poor combustion or a blocked vent pipe, which can push exhaust and carbon monoxide into your home. In either case, turn off the furnace and call us right away. If you smell gas, leave your home right away and call your gas company or 911 from outside. Once the area is safe, call us and we’ll handle the repair.24/7 Emergency Furnace Repair in Clemson & Upstate SC
