Furnace Blowing Cold Air in New Cumberland, WV? 7 Common Causes and What to Do Next

Quick Answer

If your furnace is blowing cold air in New Cumberland, check the thermostat (HEAT, AUTO) and air filter first. If it’s still not warming up, the cause might be a dirty sensor, blocked vent, or weak ignition—especially common in hillside homes where airflow and pressure fluctuate. Honest Fix Heating, Cooling & Plumbing can diagnose the issue and get your home warm again fast.

When the Heat Goes Cold in New Cumberland

Few things feel worse than waking up to a cold home on a New Cumberland morning. Whether you live near River Avenue or up on Ridge, the chill from your vents can make a long day even longer.

I’m Alex Largent, owner of Honest Fix Heating, Cooling & Plumbing. For more than 20 years, I’ve helped homeowners across the Upper Ohio Valley solve furnace problems with clear answers and reliable repairs. Some issues are as simple as a switch or filter; others take professional testing.

Here’s how to tell which one you’re dealing with—and when to call for help.

A Local Story: A Chilly Night on Ridge Avenue

Earlier this year, a couple on Ridge Avenue called because their furnace was running constantly but never produced heat. The burners would light for a few seconds, then shut down. The culprit? A clogged flue vent on the uphill side of their home. Moist air and leaves had blocked the exhaust, tripping the safety switch. After clearing the vent and checking the pressure switch, their system ran perfectly again.

They were relieved—and surprised it wasn’t an expensive fix.

What to Check First

1. Thermostat Settings
   Confirm your thermostat is on HEAT and your fan is on AUTO. The ON setting makes the blower run continuously, even between heating cycles.
2. Replace the Filter
   A dirty filter can block airflow, overheat the system, and shut off the burners. Change it and give your furnace a few minutes to reset.
3. Power and Breakers
   If your blower runs but you get no heat, check your breaker box. Reset any tripped circuits labeled Furnace or HVAC. If it trips again, call a pro—don’t force it.

If none of these fix the issue, you may be dealing with something mechanical, electrical, or gas-related that requires a technician.

7 Common Reasons a Furnace Blows Cold Air

1. Dirty Flame Sensor
   When soot or corrosion builds up, the sensor can’t verify the flame. The system shuts the burners off for safety. Cleaning it requires tools and disassembly.
2. Weak Ignitor
   If the ignitor can’t get hot enough to light the burners, your furnace will blow cold air. This is one of the most common winter repairs in New Cumberland.
3. Blocked Exhaust or Intake Vent
   Hillside homes often face wind-blown debris or ice blocking vent pipes, tripping the furnace’s safety system. Clearing the vents usually fixes it.
4. Overheating from Restricted Airflow
   Closed vents or dirty filters can cause the system to overheat and shut off burners. You’ll get cool air until it cools down and resets.
5. Pressure Switch Malfunction
   The pressure switch detects safe venting. In hilly areas, changing air pressure can cause false readings that stop the furnace from firing.
6. Faulty Control Board or Limit Switch
   If these parts fail, they can cut power to the burners or make the fan blow air without heat.
7. Aging or Undersized Furnace
   If your furnace can’t keep up or cycles endlessly, it may be undersized for your home—or simply near the end of its lifespan.
