How can I tell if my furnace flame sensor is dirty?
A dirty flame sensor usually causes the furnace to light for a few seconds and then shut off immediately. This happens because the sensor cannot detect the flame through the soot buildup and shuts off gas for safety. You can often fix this by gently cleaning the metal rod with a fine abrasive pad to restore connectivity. This simple maintenance task can save you an expensive service call if you feel comfortable opening the cabinet door.
What causes a furnace to blow cold air even when the heat is on?
The most common cause of cold air is a thermostat set to on instead of auto which runs the fan. If the setting is correct then the problem might be a failed ignitor or a tripped high limit switch. Check your circuit breaker and the pilot light if you have an older model to ensure power is reaching units. A malfunctioning gas valve could also prevent the burners from producing heat while the blower continues to push air.
Why is my furnace leaking water on the floor around the base?
High efficiency furnaces produce condensation during the combustion process which is normally drained away through a plastic tube or pump. A leak usually indicates a clogged drain line or a broken condensate pump that needs cleaning or a quick replacement. If you have a conventional furnace a water leak might actually be coming from an attached whole house humidifier system. Check the humidifier water panel and the drain lines to identify the source of the moisture before mold grows.
How do I reset my furnace after a sudden power outage?
Most modern furnaces have a simple reset button located near the blower motor housing or on the main control board. First turn the thermostat to the off position and then flip the furnace power switch to the off setting. Wait about thirty seconds before turning the power back on and then set the thermostat to your desired heat level. If the system does not restart check your main electrical panel for a tripped breaker that needs to be reset.
Still have questions?
If you are still experiencing issues the most popular advice is to check your thermostat batteries before calling a professional technician.

Frequently Asked Questions About Furnace Repair HVAC
Why is my furnace making a loud banging noise when it starts up?
A loud banging or popping sound usually indicates delayed ignition where gas builds up before finally catching the spark. This situation is often caused by dirty burners or a faulty pilot light that needs immediate professional cleaning services. You should address this quickly because the pressure from delayed ignition can eventually crack your expensive heat exchanger components. Regular maintenance prevents this buildup and ensures that your system ignites safely and quietly every single time you need it. If you hear this sound consistently call a licensed technician to inspect the burner assembly and the gas valves.
How much does the average furnace repair cost in the United States currently?
Most homeowners spend between one hundred and five hundred dollars for common furnace repairs depending on the specific parts needed. Minor issues like a dirty flame sensor or a blown fuse are typically at the lower end of that scale. However major components like a blower motor or an inducer fan can easily cost over eight hundred dollars including labor. Always request a detailed estimate before any work begins to avoid surprise fees on your final billing statement from contractors. Emergency weekend or holiday service calls usually carry a premium rate that can double the initial diagnostic fee for homeowners.
What are the signs that my furnace heat exchanger might be cracked or leaking?
Common signs of a cracked heat exchanger include soot buildup inside the furnace or a strange chemical smell near vents. You might also notice excessive moisture on windows or a yellow flickering flame instead of a steady blue heating flame. A cracked heat exchanger is extremely dangerous because it can leak carbon monoxide into your living spaces without any warning. Ensure you have working carbon monoxide detectors on every floor of your home to catch this life threatening HVAC issue. If you suspect a crack shut down the system immediately and call for an emergency professional inspection and repair.
How often should I change my HVAC filter to prevent system overheating issues?
You should change your standard one inch pleated furnace filter every thirty to ninety days depending on your household pets. A clogged filter restricts airflow which causes the heat exchanger to overheat and triggers the limit switch to shut down. This frequent cycling wears out the blower motor and significantly increases your monthly electricity and gas consumption during the winter. Check your filter monthly and replace it if you can no longer see light passing through the fiber material easily. High efficiency filters might need more frequent changes but they provide much better indoor air quality for your entire family.
Is it better to repair an old furnace or replace it with a new one?
If your furnace is over fifteen years old and the repair cost exceeds fifty percent of a new unit replacement. Modern units offer significantly higher annual fuel utilization efficiency ratings which can save you hundreds of dollars on yearly utility. Older systems often require specialized parts that are becoming increasingly difficult and expensive for local technicians to source quickly. Consider the long term savings of a new installation versus the recurring costs of patching up an aging inefficient heater. A professional load calculation can help determine if a new smaller unit might actually heat your home more effectively.
