The Importance of Regular Furnace Maintenance

If you’re reading this, chances are you’ve experienced the frustrating situation of your furnace blowing cold air when you’re expecting cozy warmth. Don’t worry; you’re not alone! At Craig’s Services in Bountiful, UT, we understand how important a functioning furnace is during those chilly winter months. 

In this blog, we’ll help you unravel the mystery of why your furnace may be blowing cold air and what you can do to fix it.

Check Your Thermostat Settings

Before diving into more complicated issues, start with the basics. Ensure your thermostat is set to “heat” and at the desired temperature. Sometimes, a simple adjustment can solve the problem.

Check Your Air Filter

A clogged or dirty air filter can restrict airflow, causing your furnace to overheat and shut down prematurely. Check your filter and replace it if it’s dirty, as it’s a quick and cost-effective solution.

Pilot Light or Ignition Issues

Older furnaces may have a pilot light that can go out. Newer models have electronic ignitions. If your furnace isn’t igniting, it won’t produce warm air. This could be due to a faulty ignition system, and you may need professional assistance to diagnose and fix the problem.

Gas Supply

If your furnace runs on natural gas, ensure that the gas supply is on and that the pilot light or ignition system is working correctly. Gas-related issues should always be handled by a trained technician for safety reasons.

Blower Motor Problems

The blower motor is responsible for circulating warm air throughout your home. If it’s malfunctioning, your furnace may blow cold air. A technician can diagnose and repair issues with the blower motor.

Ductwork Leaks

Leaky ducts can allow cold outdoor air to mix with the warm air produced by your furnace. This can result in uneven heating and the sensation of cold air blowing from your vents. Inspecting and sealing ductwork can help resolve this issue.

Lack of Maintenance

Regular furnace maintenance is crucial to keep it running smoothly. If it’s been a while since your last maintenance check, consider scheduling one to catch any potential problems early.
