Say it is a frosty evening and the house keeps getting cooler. The vents are quiet. The thermostat reads one number, and the room feels like another. A furnace problem can feel big, but it often starts small and has a few clear paths forward.
Interestingaircraft Heating & Air is a referral service. We do not repair furnaces ourselves. We connect homeowners across the Pevely area with independent heating and cooling providers who inspect the system, explain what they find, and quote the work in writing. You learn whether the fix is simple, whether a larger repair makes sense, or whether it is time to talk about replacement. Ask, then decide, with no obligation to move forward.
Smell Gas? Put Safety First
Picture this moment: you walk in and catch a rotten-egg smell near the furnace. Do not flip a switch. Do not light anything. Do not look for the source.
Walk everyone outside, then contact your gas utility or emergency services from a safe spot. Furnace repair can wait. Your safety cannot.
Other Signs to Treat Seriously
Step outside and get help if you notice any of these:
- A carbon monoxide alarm that is sounding
- Headaches or dizziness that fade when you leave the house
- Soot streaks around the furnace
- A burner flame that looks yellow or flickers
The Furnace Went Quiet: What Now?
Say you come home after a long day and the house feels like a refrigerator. No hum, no warm air, nothing. Take a breath. Many furnace stops have a simple cause, and a few minutes of checking can save a lot of guessing.
Quick Checks Before You Call
Look at the Thermostat
Make sure it is set to heat and the target is above the room temperature. Fresh batteries fix more problems than people expect.
Check Power and Switches
Furnaces often have a wall switch near the unit that looks like a light switch. Someone may have bumped it. Also check the breaker.
Inspect the Filter
A clogged filter can make the furnace overheat and shut itself off. If it looks gray and fuzzy, swap it.
Check Outside Vents
After heavy snow or a hard frost, intake and exhaust pipes can get blocked. Clear them gently if you can reach them safely.
If none of that helps, stop there. Request a callback to check provider availability and describe what you saw.
Common Signs Your Furnace Needs Repair
Not every problem arrives with a total shutdown. Watch for these:
- Rooms that heat unevenly
- Banging, squealing, or rattling sounds
- Short bursts of heat that keep starting and stopping
- Energy bills creeping up with no change in habits
- A pilot light or igniter that will not stay lit
Small signs often come before a bigger failure. A visit during the first odd noise can be simpler than a visit after a full breakdown.
How a Cold Spell Unfolds, Hour by Hour
The First Few Hours
The house loses warmth slowly at first. Closing doors, using blankets, and keeping sunny curtains open buys comfort. This is a good time to run the quick checks and reach out to a provider.
The Next Day
Walls, floors, and furniture are now cold, so the house takes longer to warm back up once heat returns. Many providers can respond quickly, but availability varies, and cold snaps keep them busy.
After Several Days
Deep frost outside puts pipes at risk, especially along outside walls and in a full basement. A frozen pipe turns a heating repair into a plumbing repair. If the house keeps dropping, ask a provider about safe ways to protect pipes while you wait.
What Happens During a Repair Visit
A good visit follows a clear path. The provider listens to your story, then checks the thermostat, power, airflow, igniter, burners, and safety controls. They explain what failed and what it takes to fix it. You should hear the price and the plan before any part comes out.
Common Furnace Repairs
- Igniter or flame sensor: the furnace tries to start, then shuts off
- Blower motor or capacitor: the burners fire, but little air moves
- Control board: the furnace acts oddly or ignores the thermostat
- Inducer motor: a loud hum or a failure to begin the start cycle
- Gas valve or pilot parts: no flame, or a flame that will not hold
Repair or Replace Your Furnace?
Picture a frame house that has seen many winters, with a furnace to match. A single worn part is usually worth fixing. A cracked heat exchanger or repeated breakdowns tell a different story.
If you search for furnace replacement near me after a big repair quote, you are asking a fair question. Providers can compare the repair cost with the age of the unit, its efficiency, and its safety condition. Ask them to put both paths in writing.
Your Options Before Work Starts
You are never stuck with one answer. Typically you can:
- Fix the part and keep the furnace
- Fix it now and plan a replacement for later
- Replace the furnace if repairs no longer make sense
- Get a second opinion before you decide
Options before work means you choose with the facts in front of you.
Questions to Ask the Provider
- What exactly failed, and can you show me?
- Is this repair likely to hold, or is another part close behind?
- What is the written quote, and what could change it?
- How old is the furnace, and what does that mean for repair versus replacement?
- Are there safety issues I should know about?
Think About Heating and Cooling Together
Many providers handle both heating and cooling, so one HVAC service visit can cover a furnace check and a look at your AC. If a hot, humid summer left you scrambling for emergency AC repair, a fall tune-up of both systems is a calm way to avoid a repeat. Ask what a seasonal check includes.
What's Included
Safety Checks
Providers look at burners, venting, and controls so you know the furnace is running safely, not just running.
Clear Diagnosis
You hear what failed and why, in plain words, before any work starts.
Written Quote
Parts, labor, and options are laid out so you can compare before agreeing.
Repair Options
Fix now, fix and plan ahead, or discuss replacement. A provider can walk you through each path.

No obligationFurnace Repair Services FAQ
Why is my furnace running but not heating the house?
Common causes include a clogged filter, a thermostat set wrong, a failing blower, or a flame sensor that needs cleaning. Try the quick checks first. If the problem stays, ask a local provider to inspect it.
How do I know if I should repair or replace my furnace?
Age, repair cost, safety issues, and how often it breaks down all matter. A provider can compare both paths in a written quote so you can decide calmly.
Will homeowners insurance cover a furnace repair?
Usually not for normal wear. Some policies may cover sudden damage, so check your policy. Providers can often help document damage for a claim.
