If your furnace is blowing cold air, it’s a clear sign that something’s amiss. Let’s delve into the common reasons behind this issue, potential causes, troubleshooting tips, and the crucial role of maintenance and repair. Understanding these facets can help ensure your furnace remains a steadfast ally against the cold.

Common Reasons Why Your Furnace is Blowing Cold Air
Several factors could be behind your furnace’s unexpected cold drafts. Here are some of the most common culprits:- Thermostat Settings: Sometimes, the solution is as simple as checking your thermostat. Ensure it’s set to “heat” and not accidentally on “cool” or “fan” mode.
- Overheating: Furnaces have built-in safety features that shut off the burners when overheating is detected, potentially leading to cold air being circulated.
- Dirty Filters: Clogged air filters restrict airflow, causing the furnace to overheat and, as a precaution, blow cold air.
- Pilot Light or Ignition Problems: For gas furnaces, a malfunctioning pilot light or ignition system can prevent the furnace from generating heat.
- Fuel Supply Issues: Insufficient gas or oil supply can hinder your furnace’s ability to produce warm air.
No Heat? Check Out These Potential Causes
When there’s no heat at all, consider these potential causes:- Ductwork Leaks: Compromised ducts can leak warm air before it reaches your living spaces, resulting in cold air output.
- Faulty Flame Sensor: A dirty or faulty flame sensor might shut off the gas valve, preventing the furnace from heating the air.
- Thermostat Malfunctions: A malfunctioning thermostat can fail to communicate properly with the furnace, leading to inadequate heating.
Furnace Troubleshooting Tips for Furnace Blowing Cold Air
Some furnace issues like a furnace blowing cold air, can be resolved on your own. Others need professional repair. When professional repair isn’t enough, replacement may be the best option. Before calling a professional, try these troubleshooting tips:- Check and adjust your thermostat settings.
- Replace or clean your furnace’s air filter.
- Ensure all vents and registers are open and unobstructed.
- Reset your furnace by turning it off, waiting a minute, and turning it back on.
- Inspect the pilot light or ignition system (for gas furnaces).

- I just wanted to thank Jake & Colby of Cornel's Plumbing, Heating & Air Conditioning. They did such an amazing job for us today. Completely … view more replaced our water heater in just 2 hours. They were very polite, knowledgeable and just plain good guys. 5 stars for sure.
- Cornell Plumbing and Heating ANSWERED THE CALL! Our furnace crapped out in the winter, it was 20+ years old so we knew it was coming but put it off until … view more it died. We were freezing for less than a day before Cornell quickly responded to our request for an inspection to see if the furnace was fixable. The inspector was very thorough and helped us understand all of the issues with our dead furnace and quickly got us connected to Randy who came over in a matter of minutes to walk through the options. Randy was very very knowledgeable and so friendly. I never felt pressured when talking to him, he was very practical and honest about what would be the best bang for our buck, while ensuring we had a solid heater for decades to come. We were on the fence about installing central AC (our house was built in 1890) but the summers in Portland have gotten so tumultuous that every year for the past four years, we've shopped around for AC quotes but just couldn't afford to commit. Randy built a great package for us that added AC to our furnace for a price that was very reasonable, so, we did it! We have a two year old and a baby on the way and we are very very thankful to know we have cool summers ahead of us and warm winters to enjoy in the comfort of our home. It's been night and day with the new furnace compared to what we were working with before. I never knew how warm our home COULD have been, until we got our new furnace installed. Oddly enough, our neighbors furnace also died like a week later and he saw we had Cornell over and asked about our experience. We were very quick to highly recommend Cornell, and my neighbor also got a new furnace from them! Needless to say, it was a smooth, quick and satisfying experience, you know, as satisfying as it can be to have to suddenly invest in heating and cooling, which can be many tens of thousands of dollars... but with the right folks, and the right system, the experience can be a sort of blessing in disguise - which it was for us!
- Jake was super helpful getting us a new water heater installed today after our very old one went out over the holidays. He was timely and tried a few other … view more solutions before we decided to fully replace it.Jake was Super kind and made sure he fully explained both the issues and the functionality of the new unit in ways that made sense to us and helped us feel confident in not only him but also Cornel’s as a whole. We will definitely keep using them for our heating and AC. Thanks Jake!
