Common Furnace Repairs and How We Fix Them
Every home is a little different, but most furnace issues fall into a few familiar patterns. Whether your system isn’t heating at all, blowing cold air, or making strange noises, our technicians have likely seen it before and know exactly how to fix it. We work on all types of heating equipment, from gas and electric furnaces to oil and dual-fuel models.
No Heat from Furnace 
If you’re getting no heat at all, it usually means something’s keeping your furnace from firing up — like a bad ignitor, tripped limit switch, or faulty thermostat. Sometimes, it’s as simple as a dirty flame sensor that shuts things down for safety. We’ll check everything from the control board to the gas line, find the root of the problem, and get your heating equipment running safely again so your house doesn’t stay cold for long.
Furnace Blowing Cold Air
When your furnace turns on but the air coming out never warms up, that’s a sign something’s off with ignition or airflow. It could be the burners not lighting, or the system overheating and shutting down to protect itself. A clogged filter or blocked duct is often to blame. We’ll inspect your vents, perform any needed air duct cleaning, and make sure air is moving freely through the system before resetting everything for consistent, steady heat.
Furnace Turning On and Off
A furnace that starts, stops, and starts again every few minutes is working harder than it should. That’s usually caused by restricted airflow, a dirty sensor, or a thermostat issue. It’s not just annoying — it can shorten the life of your furnace. We’ll clean and calibrate everything, making sure your heating equipment runs like it’s supposed to without wasting energy or wearing itself out.
Strange Furnace Noises
If you hear banging, rattling, or squealing, don’t ignore it — furnaces aren’t supposed to sound like that. Those strange noises can point to loose parts, a worn belt, or a blower motor on its way out. We’ll track down what’s making the noise, secure or replace any damaged parts, and make sure everything runs quietly and smoothly again.
Furnace Heating Unevenly
Some rooms roasting while others stay cold? That’s usually a sign of airflow problems — blocked vents, leaky ducts, or unbalanced pressure in your system. We’ll check for buildup or obstructions and recommend air duct cleaning if needed. Once we clear things up and rebalance your heating equipment, warm air will reach every corner of your house evenly again.
Bad Furnace Smells
If you catch a burning or musty smell when your furnace kicks on, it could be dust buildup, a clogged filter, or poor ventilation. A faint gas smell needs immediate attention. We’ll inspect, clean, and test your furnace to make sure it’s safe to run and not spreading dirty air through your home. You’ll have clean heat and peace of mind knowing it’s all working properly.
Weak Airflow from Air Vents
If the air coming from your vents feels weak, your furnace might be fine, but your ducts or blower aren’t doing their part. Dust buildup, a sluggish fan motor, or a blocked return vent can all cause it. We’ll inspect the system, perform air duct cleaning if needed, and fix any airflow issues so your furnace can move warm air freely through your home, even on the coldest nights.

Knowing When to Replace Your Furnace vs. Repair It
There are times when repairing your furnace just isn’t the best option. If the system is more than 15 years old, needs frequent service calls, or still leaves your house feeling unevenly heated, our technicians may recommend a new furnace. A furnace replacement can improve your home’s comfort, lower energy use, and even boost air quality by reducing dust and contaminants that build up in older units. Our professional team will walk you through your options, explain what fits your home and budget, and handle the full furnace installation from start to finish. When it’s time to replace your furnace, you’ll have clear answers, honest guidance, and a warm home you can depend on again.
Keep Furnace Problems from Coming Back with Regular Maintenance
A furnace repair might get your heat back on today, but regular maintenance is what keeps it running strong all winter. Over time, dust, debris, and normal wear can cause parts to fail or your system to work harder than it should. Routine furnace tune-ups from a professional technician help prevent those issues, improving energy efficiency, comfort, and even your indoor air quality. With the right furnace maintenance routine, your furnace can last for many years without surprise breakdowns.
Our team performs full inspections and furnace maintenance services designed to catch small problems before they turn into big ones. We recommend scheduling service once a year in the fall to keep your system safe, reliable, and ready when you need it most. During a maintenance visit, we clean components, check gas and electrical connections, test the heat exchanger, and confirm your airflow is balanced throughout the house. You’ll have peace of mind knowing your furnace is ready for another season.

Frequently Asked Questions About Furnace Repairs
How do I know if the problem is the furnace or the thermostat?
If your system isn’t responding, start by checking that the thermostat has power, is set to “heat,” and the temperature is above the current room level. If the furnace still doesn’t start, the issue is likely within the unit itself — possibly a failed control board or wiring issue. Our technicians use the latest tools to test both and pinpoint the problem quickly, giving homeowners clear solutions every time.
What is the risk of a cracked heat exchanger?
A cracked heat exchanger is serious because it can leak carbon monoxide into your space. It also lowers system efficiency and can create soot buildup or even mold from condensation leaks. If you suspect a crack—from issues like strange smells or rust—shut your system off and call our office right away. Replacing this part is essential for safety and proper furnace operation.
Why is my pilot light not staying lit?
If your pilot light keeps going out, it’s usually due to a bad thermocouple, poor gas flow, or buildup inside the burner assembly. Our team cleans the pilot and verifies proper gas pressure before relighting it safely.
What should I check if my furnace is not turning on?
First, make sure the power switch near the furnace is on, the breaker hasn’t tripped, and your air filter isn’t clogged. A dirty filter can restrict airflow and cause the system to shut down. If everything checks out, it’s time for a technician to inspect internal components. You can always call our office—or reach us by phone after hours—for fast service when your furnace won’t start.
How much does a furnace repair cost?
Furnace repair costs depend on what’s wrong and how involved the fix is. Simple repairs like replacing a flame sensor or ignitor usually run between $150 and $300+. Larger issues like blower motor replacements can cost anywhere from $700 to $1,000 or more. A good rule of thumb is the $5,000 rule: multiply the repair cost by the furnace’s age, and if that number is over 5,000, it’s usually smarter to start thinking about replacement instead.
