Furnace Not Working? Here Are The Reasons Why

When your furnace quits on a cold Alabama morning, it always feels like bad timing. You wake up with the furnace not working, the house feels colder than it should, and you start wondering what went wrong. Around Huntsville, it happens more often than you might think. Quick temperature swings, humidity, and dust from our red clay all take a toll on heating systems.

At Blake Brothers, we have been helping families across the Tennessee Valley stay warm since 1884. That is a long time, and it means we have seen just about every kind of furnace issue you can imagine. If your system is acting up, here are some things to check and how to know when it is time to call in our team.

Why Is My Furnace Not Working?

Sometimes it is something simple. Other times, it takes a professional to find the real problem. A few of the usual suspects include:

• A clogged or dirty air filter blocking airflow
• A thermostat set wrong or with dead batteries
• A tripped breaker or blown fuse
• Ignition or pilot light problems
• A bad blower motor or worn fan belt
• Safety switches that keep the furnace from overheating

If you have already checked the basics and the furnace still will not kick on, give us a call. We can run a full diagnostic and get your heat back on quickly.

Common Furnace Problems in North Alabama Homes

After 140 years in business, we see patterns. These are the issues our technicians find most often in homes around Huntsville, Decatur, Madison, and Athens:

• Dirty filters: Our air gets dusty fast here, especially during dry months. Filters clog quicker than most homeowners expect.
• Pilot light out: Older gas furnaces can have pilot lights that flicker or go out completely.
• No heat from vents: Usually duct leaks, ignition issues, or a worn blower motor.
• Thermostat trouble: Loose wires, old units, or bad sensors can throw off temperature readings.
• Condensate drain blockage: Common in high-efficiency units, especially in humid weather.
• Ignition failure: Electronic igniters fail more often when the system has not been serviced in a while.

How Huntsville Weather Affects Furnace Performance

Winters in North Alabama are unpredictable. One week it is mild, the next we are scraping frost off the windshield. That back-and-forth is tough on heating equipment. Frequent cycling wears down motors and burners faster than in places where temperatures stay steady.

Humidity is another factor. Our mix of damp air and dust can lead to corrosion inside the unit and clog filters sooner than you might think. If your furnace has not been cleaned since last season, there is a good chance it is struggling against buildup right now.

DIY Furnace Repair Checks Before Calling a Technician

A few quick checks can save you a service call:

• Make sure the thermostat is set to “heat” and the batteries work.
• Check your circuit breaker and the on/off switch near the furnace.
• Replace the air filter if it looks gray or dusty.
• Make sure your vents are open and not blocked by furniture.
• If you have a gas furnace, make sure the gas valve is on.

If you have tried all of this and the furnace still will not start, that is when it is time for a professional.

• Clean burners, blower parts, and heat exchangers

• Replace filters
• Test airflow and carbon monoxide levels
