A well-functioning furnace is essential for keeping your home warm and comfortable, especially during the coldest months of the year. But like any appliance, furnaces can develop issues over timeβsome minor, others requiring immediate attention.
Ignoring early warning signs can lead to costly repairs, system failure, or even safety hazards like gas leaks or carbon monoxide exposure.
At Brecht Tech Services, we specialize in professional furnace repair and maintenance, ensuring your heating system runs efficiently and safely. This guide will help you identify:
β Common signs your furnace needs repair
β How delaying repairs can increase costs
β When to call for emergency furnace service
If your furnace isnβt heating properly, making strange noises, or driving up your energy bills, donβt waitβread on to learn when itβs time to schedule repairs.
1. Your Furnace Is Blowing Cold Air
If your furnace is running but only blowing cold or lukewarm air, itβs a clear sign of a malfunction. Common causes include:
β A malfunctioning thermostatβIncorrect settings or a faulty sensor can prevent proper heating.
β Pilot light or ignition issuesβGas furnaces need a properly working ignition system to generate heat.
β Clogged filters or ductsβRestricted airflow can cause heating issues.
π Pro Tip: Try resetting the thermostat and checking for clogged air filters before calling a technician.
2. Unusual Noises Coming from the Furnace
A well-functioning furnace should operate quietly. If you hear banging, screeching, rattling, or whining sounds, it could indicate:
β Loose or broken components β Rattling or clanking noises may signal loose internal parts.
β Blower motor failure β Squealing or screeching often means the motor belt is worn out.
β Dirty burners β Loud booming sounds when the furnace turns on can mean delayed ignition due to burner buildup.
π Pro Tip: Turn off the furnace immediately if you hear loud booming or screeching soundsβthis can indicate a dangerous gas buildup.
3. Your Energy Bills Have Skyrocketed
If your heating bill has suddenly increased without a change in usage, your furnace may be:
β Losing efficiency due to age or wear
β Working harder due to a clogged air filter or duct leaks
β Experiencing thermostat or sensor issues
π Pro Tip: Compare your heating bills to last winterβs usageβa significant spike is a sign of furnace inefficiency.
4. Frequent Cycling (Turning On and Off Repeatedly)
A properly functioning furnace follows a regular heating cycle. If your furnace constantly turns on and off, it may be due to:
β A clogged air filter β Dirty filters restrict airflow, causing overheating.
β A faulty thermostat β If the thermostat isnβt reading temperatures correctly, it may signal the furnace to shut off prematurely.
β Short cycling due to overheating β This can cause long-term damage if ignored.
π Pro Tip: Check the thermostat settings and air filter firstβif the problem persists, call a technician.
5. Your Furnace Emits a Strange Smell or Gas Odor
π¨ Gas smells require immediate attention! If you detect a strong gas smell (like rotten eggs) near your furnace:
β Turn off the furnace and gas supply immediately.
β Do NOT use electrical switches or appliancesβsparks can ignite gas leaks.
β Evacuate and call a professional immediately.
If the furnace emits a burning or musty smell, it may indicate:
β Dust buildup β Normal if the furnace hasnβt been used for a while.
β Electrical issues β Overheating components can produce a burning plastic smell.
π Pro Tip: If the smell lingers for more than a few hours, call for a professional inspection.
6. Pilot Light or Ignition Issues (Gas Furnaces Only)
β A pilot light should burn blueβif itβs yellow, this may indicate a carbon monoxide leak.
β A flickering or weak pilot light could mean a ventilation problem or gas supply issue.
β If the pilot light wonβt stay lit, the thermocouple may need replacement.
π Pro Tip: A yellow or orange flame means your furnace isnβt burning fuel properlyβthis can lead to dangerous CO emissions.
7. Youβre Constantly Adjusting the Thermostat
If some rooms feel too hot while others are too cold, your furnace may be struggling due to:
β A malfunctioning thermostat
β Blocked air ducts causing uneven heating
β A failing blower fan that isnβt distributing air properly
π Pro Tip: If you find yourself constantly adjusting the thermostat, your furnace may need repair or recalibration.
8. Your Furnace Is More Than 10β15 Years Old
β Most furnaces last 12β20 years with proper maintenance.
β If your furnace requires frequent repairs, replacing it may be more cost-effective.
β Newer furnaces are more energy-efficient, saving money on heating bills.
π Pro Tip: If your furnace is over 15 years old and struggling, a new unit may be a better long-term investment.
Why Timely Furnace Repair Saves You Money
Delaying furnace repairs can lead to:
β Higher repair costs β Small issues worsen over time.
β Increased energy bills β A struggling furnace uses more fuel to maintain temperatures.
β Sudden breakdowns β Ignoring minor problems could leave you without heat in freezing temperatures.
β Safety hazards β Gas leaks or carbon monoxide risks can endanger your home.
β Scheduling timely repairs prevents costly replacements and ensures your home stays warm and safe.
