Why Your Furnace is Blowing Cold Air and What to Do
When your furnace runs but fails to produce heat, it's a frustrating and uncomfortable problem, especially during a Kansas winter. The good news is that some causes are simple fixes you can handle yourself, while others require professional help. This guide will walk you through troubleshooting steps and explain when to call for expert furnace repair in the Basehor area.
Quick Answer: Common Causes & Solutions
- Thermostat Issue: Check if it's set to "Heat" and "Auto" (not "On").
- Dirty Air Filter: Replace if clogged (most common DIY fix).
- Pilot Light Out: Relight following manufacturer instructions.
- Flame Sensor Dirty: Requires professional cleaning.
- Gas Valve Problem: Needs immediate professional repair.
- Ignition Failure: Call an HVAC technician right away.
For immediate assistance, contact Mr. Breeze Heating and Cooling for fast, reliable furnace repair.
First Steps: Simple DIY Furnace Checks
Before you find HVAC repair services near Basehor, KS, performing a few simple checks can often resolve the issue and save you a service call.
- Thermostat Settings: Ensure your thermostat is set to "Heat" and the fan is on "Auto," not "On." The "On" setting makes the fan run constantly, circulating unheated air between heating cycles. Also, replace the batteries if your thermostat uses them, as low power can disrupt communication with the furnace.
- Clogged Air Filter: A dirty filter is a top cause of furnace issues. It restricts airflow, which can cause the furnace to overheat and shut down its burners. Inspect your filter; if it's clogged with dust and debris, replace it. We recommend changing filters every 1-3 months. For more details, see our guide on More info about furnace maintenance.
- Tripped Circuit Breaker: Your furnace has a dedicated circuit breaker. If it has tripped, it will cut power to the unit. Find your electrical panel and locate the breaker for your furnace or HVAC system. Flip it fully to the "Off" position, then back to "On."
- Pilot Light Status: Older furnaces use a small, continuous flame called a pilot light to ignite the burners. If it has gone out, the furnace cannot produce heat. Instructions for safely relighting it are usually printed on the furnace unit. Follow them carefully.
Understanding the Problem
A furnace blowing cold air means there's an interruption in its heating cycle. Normally, your thermostat signals for heat, which activates an igniter or pilot light. A gas valve opens, the burners ignite, and the flames heat a component called the heat exchanger. The blower fan then pushes air over the hot exchanger and distributes warm air through your vents. If the heating part of this sequence fails—due to a faulty igniter, gas supply issue, or a dirty sensor—but the blower fan still runs, you will feel cold air.
Common Causes for a Furnace Running but Blowing Cold Air
If the simple DIY checks covered earlier haven't restored your heat, the problem likely lies with an internal component. These issues are more complex and often require professional expertise to diagnose and repair safely.
Complex Issues That Require You to Find HVAC Repair Services near Basehor, KS
Attempting to fix these problems yourself can be dangerous and may lead to further damage. It's best to call a trained technician if you suspect one of the following issues:
- Faulty Flame Sensor: This crucial safety device confirms that the gas burners have ignited. If the sensor is dirty or has failed, it will shut off the gas supply to prevent a hazardous gas buildup. The furnace will attempt to light a few times before stopping the heating process, but the fan may continue to run.
- Malfunctioning Gas Valve: The gas valve controls the fuel flow to the burners. If it's stuck closed or not receiving the correct electrical signal, the burners won't get the gas they need to ignite. Due to the dangers of working with gas lines, this repair should only be handled by a licensed professional.
- Clogged Condensate Drain Line: High-efficiency furnaces produce condensation that must drain away. If the drain line gets clogged with debris, a safety switch will shut down the furnace to prevent water damage. The blower may still operate, but the heating cycle will be disabled.
- Ignition System Failure: Modern furnaces use a hot surface igniter or an intermittent pilot to light the burners. These components can crack, wear out, or fail due to electrical issues. Without a working ignition system, the furnace cannot create heat.
- Blower Motor or Limit Switch Issues: A faulty limit switch can cause the blower to run continuously even when the burners aren't on. While the motor itself is running (which is why you feel air), a problem with its controls or the motor itself can prevent the heating cycle from operating correctly.
These complex issues require the trained eye and specialized tools of an HVAC technician. For reliable solutions, you can find More info about furnace repair on our dedicated page.

Signs You Need an Emergency Repair
Some furnace issues demand immediate action. If you experience any of the following, it's time to find HVAC repair services near Basehor, KS right away.
- Smell of Gas or Rotten Eggs: This indicates a potential gas leak. Evacuate your home immediately without using any electronics or light switches. Once safely outside, call your gas company, then call us for emergency service.
