Heater Repair in Poteau, OK: What to Check First + When to Call
When it gets cold in Poteau, your heater always seems to pick the worst time to act up. If your system is running but not warming the house (or it won’t turn on at all), this page will help you figure out what’s going on without turning it into a DIY repair project.
A lot of homeowners just want one thing: heat back on fast. If you’re in that boat, do the quick safe checks below. If it doesn’t fix it, it’s usually a real mechanical or electrical issue that needs tools and testing—and that’s where we come in.
If you need heater repair in Poteau, OK, call Clark HVAC at (918) 839-3734. We offer 24/7 service and can handle furnaces, heat pumps, and mini-splits.
Before anything: 2 safety rules
If you smell gas, shut the system off and leave the area. Don’t keep trying to restart it.
If your carbon monoxide alarm goes off, treat it as an emergency and get fresh air.
If there’s no gas smell and no CO alarm, you can run through the safe checks below.
5 quick safe checks (that won’t replace a service call)
These are the same “easy stuff” we ask about on the phone because they can save you time. They don’t involve opening panels or messing with wiring.
1) Thermostat settings
Make sure it’s set to:
HEAT
Temperature set 3–5 degrees above the current room temp
If your thermostat uses batteries, replace them.
2) Breaker and power switch
Heaters can lose power even when the thermostat looks normal. Check:
The HVAC/furnace breaker in your panel
Any nearby wall switch that controls the furnace/air handler
If it trips again right away, stop resetting it and call us.
3) Air filter
A dirty filter can cause overheating, short cycling, and safety shutdowns. If you haven’t changed it recently, swap it out and try again.
4) Vents and airflow
Make sure supply vents aren’t blocked by rugs/furniture, and return air grilles aren’t covered. Airflow problems make heaters “act broken,” even when the equipment is fine.
5) System mode (heat pump homes)
If you have a heat pump, avoid bouncing between modes (HEAT/OFF/COOL). Pick HEAT and let it run a bit.
If you did those 5 things and it’s still not heating, it’s usually time to call.
Signs you should stop troubleshooting and call a pro
If you’re seeing any of these, it’s not “basic settings” anymore:
Heater turns on then shuts off within a couple minutes (short cycling)
You hear repeated clicking/trying to start, but no heat
Heat pump runs forever but the house temperature doesn’t climb
Burning electrical smell, buzzing, or hot plastic smell
You’ve reset a breaker once already and it keeps tripping
Uneven heat (some rooms cold, others hot) that won’t improve
At that point, you’re paying in time, stress, and risk. A fast diagnostic is usually cheaper than guessing.
Common “no heat” problems we fix in Poteau
Furnace problems (gas or electric)
Some of the most common causes behind a “no heat” call are:
Ignition or flame-sensing issues
Airflow problems that trip safety limits
Weak/failed blower components
Control board problems
Thermostat or low-voltage control issues
These require testing, not guessing.
Heat pump problems
Heat pumps are great when they’re working right, but a few issues show up a lot:
Defrost problems (system gets stuck or never defrosts)
Auxiliary/backup heat not kicking in when it should
Refrigerant or airflow issues that reduce heating capacity
Outdoor unit problems (fan/motor/contactors)
“Is it normal for my heat pump to steam outside?”
Yes—sometimes.
When it’s cold and damp, the outdoor coil can frost up. Heat pumps run a defrost cycle to clear that frost, and you can see steam coming off the outdoor unit. That part can look scary, but it’s often normal.
What’s not normal:
It’s steaming constantly all day
Your system is stuck in a pattern of defrosting over and over
The house never warms up and it feels like it’s blowing lukewarm air forever
If that’s happening, call us and we’ll check airflow, sensors, defrost operation, and system performance.
Why “cranking the thermostat” can make heat pump bills worse
With many heat pump setups, jumping the thermostat way up can trigger backup/aux heat (electric strip heat) depending on the system setup. That can raise electric usage fast.
A better move is nudging the setpoint up gradually—or just call us if the heat pump can’t keep up. A heat pump that’s running nonstop and not gaining temperature usually has a real issue.

Quick FAQ (Poteau heater questions)
Why is my heater blowing cold air?
It can be normal for a brief moment at startup, but if it stays cold, it’s often airflow-related, control-related, or (for heat pumps) a performance/defrost/aux heat issue.
My heater turns on then shuts off—what does that mean?
That’s usually short cycling. Common causes include airflow restriction, safety limit trips, sensors, or control problems.
How fast can you get to Poteau?
If it’s a no-heat situation, call and we’ll give you the quickest availability. We offer 24/7 service for emergencies.
Should I keep resetting the breaker?
No. If it trips once and comes right back, stop resetting it. Repeated trips usually mean an electrical fault, failing motor, or a short that needs testing.
