If you’re experiencing cool air blowing from your furnace in Seattle, WA, it can be a frustrating and uncomfortable situation. At All Climate Heating & Air Conditioning, we understand the importance of a properly functioning furnace, especially during the colder months. In this article, we’ll explore some of the common reasons why your furnace may be blowing out cool air and what you can do to resolve the issue.

Thermostat Settings

One of the most common reasons for a furnace blowing out cool air is incorrect thermostat settings. Make sure your thermostat is set to “heat” mode and that the desired temperature is higher than the current room temperature. If your thermostat is set to “cool” or “fan” mode, your furnace will not produce warm air.

Dirty Air Filter

A dirty or clogged air filter can restrict airflow and cause your furnace to overheat, leading to cool air being blown out. It’s essential to replace your air filter regularly, typically every 1-3 months, depending on usage and environmental factors. A clean air filter not only ensures proper airflow but also improves indoor air quality and the overall efficiency of your heating system.

Pilot Light Issues

If you have an older furnace with a standing pilot light, a malfunctioning or extinguished pilot light can prevent your furnace from producing warm air. Check to see if the pilot light is lit. If it’s out, follow the manufacturer’s instructions to relight it safely. If you’re unsure or uncomfortable doing this, contact a professional heating service technician for assistance.

Malfunctioning Flame Sensor

A flame sensor is a safety device that ensures proper ignition and monitors the presence of a flame in your furnace. If the flame sensor is dirty or malfunctioning, it may not detect the flame, causing the furnace to shut down prematurely and blow out cool air. A professional furnace repair technician can clean or replace the flame sensor to restore proper function.

Insufficient Gas Supply

If your furnace is not receiving enough gas, it may not be able to produce adequate heat. This can be due to a closed gas valve, a malfunctioning gas regulator, or a leak in the gas line. If you suspect a gas-related issue, it’s crucial to contact a licensed professional immediately to address the problem and ensure your safety.

Overheating Furnace

An overheating furnace can cause the system to shut down as a safety precaution, resulting in cool air being blown out. Overheating can be caused by various factors, such as:

• Dirty air filters
• Blocked vents or registers
• Malfunctioning blower motor
• Restricted airflow due to closed dampers or collapsed ductwork

Regular maintenance and inspections can help prevent overheating issues and ensure your furnace operates efficiently and safely.
