Smell Gas? Put Safety First
Gas smells like rotten eggs. If you smell it, stop reading and act.
- Get everyone out, pets too.
- Do not flip switches or use a lighter.
- Do not use your phone inside.
- Call the gas company or 911 from outside.
- Wait for the all-clear before you go back in.
A gas leak is not a do-it-yourself job. Once it is safe, you can look for furnace help.
Watch for Carbon Monoxide
Carbon monoxide (CO) is a gas you cannot smell. A damaged furnace can make it. Headaches, dizziness and nausea are warning signs. Go outside and call 911 if you feel sick. Test your CO alarms each season.
Quick Checks Before You Ask for Help
These checks take a few minutes. Some fix the problem. All of them give a provider useful clues.
Start With the Thermostat
Set it to heat. Set the temperature a few degrees above the room. Put in fresh batteries if it has them.
Check Power and Water
Most furnaces have a switch that looks like a light switch. Make sure it is on. Look at the breaker panel too. In a basement, look for water near the unit. After spring flooding or a sump pump failure, do not touch standing water near the furnace. Ask a provider for help.
Swap a Dirty Filter
The filter is a paper screen that catches dust. When it clogs, air cannot flow. The furnace may overheat and shut itself off.
Clear the Outside Vents
Deep frost and heavy snow can block the vent pipes outside. Gently clear snow away. Do not poke anything inside the pipes.
Still no heat? Stop trying fixes and ask for help.
Signs Your Furnace Needs Repair
Some signs mean act today. Others mean plan a visit soon.
Act Fast
- A burning smell that does not fade
- A yellow or flickering burner flame (it should be steady and blue)
- A CO alarm that sounds
- Soot around the unit
Turn the furnace off and get help.
Plan a Visit Soon
- Weak heat or cold rooms
- Bangs, squeals or rattles
- Short cycling, which means it starts and stops again and again
- Higher heating bills with no change in habits
What Happens During a Repair Visit
A provider starts by asking what you saw and heard. Then they check the thermostat, filter, ignition, flame, blower and vents. They also test safety controls.
Next, they explain the problem in plain words. You should get a written quote before work begins. You say yes or no. Nothing starts until you agree.
Common Furnace Repairs
Igniter and Pilot Trouble
The igniter is the part that lights the gas. It wears out with age. A weak one can leave you with no flame.
Dirty Flame Sensor
This small rod tells the furnace the flame is on. When it gets dirty, the furnace shuts down. A cleaning often solves it.
Blower and Motor Problems
The blower pushes warm air through your home. A worn motor or fan can make noise or move little air.
Control Board and Wiring
The control board is the furnace's brain. A bad board or loose wire can cause odd starts and stops.
Cracked Heat Exchanger
The heat exchanger keeps burner gases apart from your home air. A crack is a safety issue. It often points toward replacement.
Repair or Replace Your Furnace?
Many furnaces last about 15 to 20 years. Older frame houses and bungalows may also have tired ductwork, so ask about that too.
Think about replacement if:
- The unit is near or past 15 years old.
- Repairs keep coming back.
- A repair costs close to half of a new unit.
- The heat exchanger is cracked.
If you search for furnace replacement near me, ask each provider to explain both paths. Ask for the repair price and the replacement price side by side. Know your options, then decide.
Get Your Photos and Notes Ready
A little prep makes any estimate clearer.
- Take photos of the unit, the label with the model number, and any error light.
- Write down the noises, smells and the date trouble began.
- Note the last filter change and service date.
- Keep old bills and warranty papers in one folder.
Photos and notes save time. They also help you compare quotes fairly.
Questions to Ask the Provider
- Is the provider licensed for work in this state?
- What is the written price, and what does it include?
- Is there a warranty on parts and labor?
- What are my options besides this one?
- How long will the work take?
- Will the old part be shown to me?
Ask, then decide. A good provider is glad to answer.
Insurance and Your Records
Some policies may cover sudden damage. Many do not cover wear and age. Check your policy. Providers can often help document damage for a claim. Keep your photos, notes and quotes together.

FAQ
Residential Furnace Repair FAQ
Why is my furnace running but blowing cold air?
It could be a dirty filter, a flame sensor that needs cleaning, or an igniter problem. Check the thermostat and filter first. If the air stays cold, ask a local provider to take a look.
How much does furnace repair cost?
Many repairs fall between about $100 and $1,500, depending on the part. Big jobs like a heat exchanger cost more. Prices vary, so ask for a written quote.
Should I repair or replace an old furnace?
If the furnace is over 15 years old and repairs are frequent, replacement may make sense. Ask providers for both prices, then compare them side by side.
