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

Quick Answer

If your furnace is blowing cold air in Colliers, check that it’s set to HEAT, the fan is on AUTO, and your filter isn’t clogged. If those look good, it may be a failing ignitor, blocked drain line, or airflow problem—especially common in Colliers basements where moisture and temperature swings affect older ductwork. Honest Fix Heating, Cooling & Plumbing can help you get the heat back quickly and safely.

When the Heat Goes Cold in Colliers

When cold air starts pouring from your vents on a freezing Colliers morning, it’s never at a good time. Whether you’re up on Pursel Hill or near Hogan’s Run, a furnace blowing cold air can throw your whole home off balance.

I’m Alex Largent, owner of Honest Fix Heating, Cooling & Plumbing. I’ve spent more than 20 years serving homes across the Upper Ohio Valley, and I’ve seen just about every way a furnace can lose heat—from rusted flame sensors to collapsed duct joints.

Below, I’ll show you what to check before calling a technician—and when it’s time to bring in a pro.

A Local Story: Cold Air on Pursel Hill Road

A homeowner on Pursel Hill Road called last winter because their furnace kept shutting off mid-cycle, leaving the house cold. The issue turned out to be a clogged condensate drain. Moisture had built up in the line, triggering a safety switch. We flushed the drain, cleaned the flame sensor, and tested the system—it ran perfectly after that.

No parts needed. Just honest work done right.

What to Check Before You Call

1. Thermostat Settings
   Double-check that it’s set to HEAT and the fan is on AUTO. If it’s set to ON, the fan will run constantly—even when the furnace isn’t heating.
2. Air Filter Condition
   If your filter looks dark or dusty, change it. Blocked airflow can cause overheating, making the system shut down its burners for safety.
3. Circuit Breakers and Switches
   Check your electrical panel for any tripped breakers labeled Furnace or HVAC. Also, make sure the furnace’s service switch (usually near the unit) is on.

If your furnace still won’t heat after these steps, the problem likely involves sensors, gas flow, or electronics—things that require professional tools.

7 Common Causes of a Furnace Blowing Cold Air

1. Dirty or Rusted Flame Sensor
   Colliers basements tend to hold moisture, which can rust sensors and cause false readings. If the sensor can’t detect flame, it shuts down the burners for safety.
2. Faulty Ignitor
   If your ignitor is cracked or weak, it can’t light the gas. This is one of the most common causes of no-heat calls during cold snaps.
3. Blocked Drain or Condensate Line
   If your furnace can’t drain properly, the safety switch will stop ignition. Moisture problems are common in low-lying Colliers basements.
4. Overheating from Blocked Airflow
   A dirty filter or closed vent can cause the furnace to overheat and shut down its burners. It’ll keep blowing cool air until it resets.
5. Faulty Limit Switch or Control Board
   These electrical components regulate blower timing and burner operation. When they fail, the furnace might run the fan without heat.
6. Leaky or Uninsulated Ducts
   Warm air can escape through unsealed ducts in crawlspaces or uninsulated basements—common in older homes off Eldersville Road.
7. Undersized or Aging Furnace
   If your system runs constantly without heating the house, it might be undersized or simply past its prime.
