When winter temperatures drop in Oklahoma City, your furnace becomes one of the most important systems in your home. But what happens when it stops working properly?
At Hill & Co., we know that understanding common furnace issues can help you catch small problems before they turn into costly repairs. In this guide, we’ll walk you through some of the most frequent furnace repair problems, their symptoms and what you can do to keep your home warm and comfortable all season long.
Symptoms: No heat, no fan noise, no response when adjusting the thermostat
Possible Causes:
Solution: First, check the thermostat settings and replace the batteries if needed. Next, ensure the breaker hasn’t tripped. If these don’t resolve the issue, the ignition system may need professional repair.
Symptoms: Furnace runs, but airflow is weak or nonexistent
Possible Causes:
Solution: Change your furnace filter regularly to prevent clogs. If airflow remains weak, it may be due to a faulty blower motor or leaky ducts, which require professional inspection and repair.
Symptoms: Furnace runs but only blows cool or lukewarm air
Possible Causes:
Solution: If you have a gas furnace, check that the pilot light is on. If the flame sensor is dirty, it may need cleaning or replacement. An overheating furnace often results from a dirty filter or airflow issues — try replacing the filter before calling a professional.
Symptoms: Furnace starts and stops frequently, struggling to maintain the desired temperature
Possible Causes:
Solution: Change the air filter and check the thermostat settings. If the issue persists, it may be due to an incorrectly sized furnace, which requires a professional assessment.
Symptoms: Banging, rattling, squealing or whistling noises
Possible Causes:
Solution: If you hear banging or rattling, turn off the furnace and check for loose panels. High-pitched squealing often indicates a worn-out blower belt, while persistent loud noises may signal a failing blower motor or burner issue. These problems require prompt professional attention.
Symptoms: Burning, musty or gas-like odors when the furnace runs
Possible Causes:
Solution: If you smell gas, turn off your furnace immediately, leave your home and call your gas company. A burning smell often indicates dust buildup or a clogged filter, which can be resolved by replacing the filter.
Symptoms: Sudden or unexplained increase in heating costs
Possible Causes:
Solution: Routine maintenance, including filter changes and duct inspections, can help improve efficiency. If your furnace is more than 15 years old, upgrading to a more efficient model could save you money in the long run.
